Terminology

This document uses the following terms:

host A computer that is or will be connected to a CLARiiON® storagesystem. This computer is called either a management station or aserver, depending on how it is or will be connected to the storagesystem.

management station A host from which you manage CLARiiON storage systems. Itmust be on the same network as the storage-system managementports. A management host may also be a server.

server A host that is already or will be connected over a network to theiSCSI ports on a CLARiiON storage system. A management hostmay also be a server.

new server A server that is not already connected to or set up for a CLARiiONstorage system.

existing NIC or iSCSIHBA

The network interface card (NIC) or iSCSI host bus adapter (HBA)that is already installed in a server.

new NIC or iSCSI HBA The NIC or iSCSI HBA that was not already installed in the server.

base dual-SP system An AX4-5 series system with two storage processors (SPs) — anAX4-5 or AX4-5i storage system.

expansion dual-SPsystem

An AX4-5 series system with two storage processors (SPs) —an AX4-5 or AX4-5i storage system — with the expansion packenabler installed.

new storage system A storage system that is not connected to a server or configuredfor storage. It is just as it was shipped to you.

field-replaceable unit(FRU)

A storage-system component that you can add to your storagesystem or replace in your storage system at your site. Examplesof FRUs are disks andpower/cooling modules.

DPE-AX A disk processor enclosure that contains 1 or 2 storage processors(SPs) and 4 to 12 disks.

DAE-AX A disk-array enclosure that provides additional storage for aDPE-AX with 2 storage processors and an expansion packinstalled. Each DAE-AX supports a maximum of 12 disks.

storage processor (SP) A printed-circuit board with processors, memory modules, andcontrol logic that manages the I/O between the server and thedisk modules.

disk pool A set of disks with the same capacity and RAID type on which youcreate one or more virtual disks.

virtual disk A grouping of physical disk partitions into one span of disk storagespace. Each virtual disk you create is distributed equally acrossthe disks in the disk pool. A virtual disk looks like an individualdisk to the server’s operating system. A virtual disk is created withNavisphere® Express.

initiator A NIC or iSCSI HBA port that issues requests to send data to orreceive data from a target in the storage system.

target A storage-system SP port that accepts and responds to requestsfrom an initiator. Such a port is called an iSCSI data port.

CHAP Challenge Handshake Authentication Protocol. An optionalsecurity mechanism to control access to an iSCSI storage systemover the iSCSI data ports.

iSNS Microsoft Internet Storage Naming Service (iSNS) providesautomated discovery, management and configuration of iSCSIdevices.

An AX4-5i storage system has two SPs, so it is called a dual-SP system.


Before you start

❑ Review the support matrix on the Service & Support page of thestorage-system support website to confirm that the following aresupported:

The server hardware that will access the storage system.

The operating system version running on the server hardware.

❑ Read the release notes for your storage system, which are availableon the Service & Support page of the storage-system supportwebsite.

The url for the storage-system support website is in the Documentation andSupport document that shipped with your storage system.

For a new storage-system installation, you will need to:

❑ If you ordered a rackmount cabinet for your storage system –To review the Site Preparation Guide for the 40U-C Cabinet, whichshipped with the cabinet, to ensure that the site in which you wantto install the storage system meets the site requirements. This guideis on the resources and documentation CD that shipped with thesystem and is available on in the Technical Documentation andAdvisories section on the Powerlink website. Especially importantis confirming that your facility has appropriate electrical wiring inplace to accommodate your cabinet’s power cables. To support allof the storage system’s high-availability features, the cabinet mustreceive power from two discrete circuits.

❑ To verify that your facility has:

Electrical wiring in place to accommodate your installation’spower cables. To support all the storage system’shigh-availability features, you must receive power from at leasttwo separate circuits.

Adequate network wiring to provide each storage-systemstorage processor (SP) management port with a discrete Ethernetconnection and IP address. The storage-system managementports can connect to either a 10/100/1000 or 1-gigabit EthernetLAN. EMC recommends a 1-gigabit Ethernet LAN for bestperformance.


5

http://Powerlink.EMC.com

❑ The following network information from the person responsiblefor your network:

Static IP address for each SP in the storage system.

Subnet mask for the LAN to which you will connect thestorage-system management ports.

Default gateway for the LAN to which you will connect thestorage-system management ports.

Storage-system iSCSI network information, including staticIP address, subnet mask, and default gateway for eachstorage-system iSCSI port that you will use.

The network configuration information, including the IPaddress and network mask, for any NICs or iSCSI HBAs thatyou are installing.

Optional iSNS server information.

❑ CAT 5 or higher Ethernet network cables for storage-systemmanagement port connections (one per SP).

For any installation, you will need:

❑ A Navisphere management station with a supported Internetbrowser for running Navisphere Manager and on the same networkas the storage-system management ports. This host can also bea server. For supported host and browsers, refer to the E-Lab™Interoperability Navigator on the Powerlink website.

❑ A supported Windows host on the same subnet as thestorage-system management ports. You can use this host:

As a Navisphere management station

To initialize the storage system

To run the Navisphere Service Taskbar, which runs only ona Windows host.

As a CLARalert® monitor station, which must be a Windowshost, but cannot be a server (that is, it cannot send I/O to thestorage-system data ports).

❑ A Windows 2000, Windows Server 2003 or Windows Server 2008host that is or will be a server with iSCSI connections to the storagesystem. This server must have a supported server configuration;that is, it must have all required updates, such as hot fixes orpatches, installed.



❑ A Navisphere® management station with a supported Internetbrowser that is on the same network as the storage-systemmanagement ports. This host can also be the server. For supportedInternet browsers, see the AX4-5 release notes on the Service &Support page of the storage-system support website.

❑ A CAT 5, CAT 5e, or CAT 6 Ethernet network cable (100 metersmaximum) for each iSCSI port that will connect the storage systemthough network routers or switches to the NICs or iSCSI HBAsin the server. We recommend CAT 6 cables for best performance.These cables may already be connected for a configuration with anexisting storage system or existing server.

For cable specifications, refer to Technical Specifications on the Learnpage of the storage-system support website.

❑ For a network configuration, Ethernet network cables as neededfor the hosts. These cables may already be connected for aconfiguration with an existing storage system or existing server.

We recommend discrete networks dedicated to iSCSI traffic. In a serverwith multiple NICs or iSCSI HBAs that are connected through networkrouters or switches to the storage system, each NIC or iSCSI HBA initiatorport must be on a separate subnet.

For cable specifications, refer to Technical Specifications on the Learnpage of the storage-system support website.

❑ A method for writing data to a virtual disk on the storage systemthat will test the paths from the server to the storage system. Youcan download an I/O simulator (Iometer) from the followingwebsite: http://www.iometer.org/.

Connecting the storage-system expansion ports

IMPORTANT The expansion cables are keyed and marked orto indicate the connector.

If your storage system includes optional DAE-AXs, connect theexpansion ports between the storage processors (SPs) in the DPE-AXand the DAE-AXs as follows: (Figure 8):

The expansion port on each SP connects to the correspondingprimary port on the first DAE-AX in the loop; that is, the expansion

port on SP A, on the right, connects to the port on the linkcontrol card directly above it (LCC A), and the expansion porton SP B, on the left, connects to the port on the link control carddirectly above it (LCC B).

The DAE-AX expansion ports connect to the next primaryports in their loops.

Connecting the cabinet to a power source

If the storage system is in a rack or cabinet, connect the cabinet or rackAC power cables to the power outlets in your facility.

In general, EMC cabinets use two 240-volt AC cables. You shouldconnect power cables on either side of the cabinet to different branchcircuits. Connecting to only one branch circuit will degrade thesystem’s high availability. Some cabinet configurations may exceedthe 24A derating supported by a single pair of power sources/branchcircuits, called power distribution units (PDUs). These configurationsuse a second pair of PDUs – the upper two in your cabinet. Since eachactive PDU requires a separate power source, a fully configured cabinetuses a total of four 240V branch circuit source connections.


Powering up the storage system

1. Power up each standby power supply (SPS A and SPS B) bypressing the right side of the SPS power switch (Figure 13).

CL3781

Figure 13 On position for the SPS switch (SPS A shown)

2. If the storage system is installed in a cabinet or rack, turn on themaster switch/circuit breakers for each cabinet or rack power strip(PDU).

3. Press the power button on SP A (Figure 14).

When SP A powers up, SP B powers up automatically.

The storage system takes 8 to 10 minutes to complete its first powerup.Green activity lights flash during power on self-test (POST), and thenthe lights go off or remain steady. If you installed disk modules inDPE-AX slots 0-3, the system writes vital information to these disksduring the first powerup. This process extends the first powerup by 25to 30 minutes.

The system fault light on the front of the DPE-AX and the SPS recharge lightson the rear of the SPS commonly stay on for several minutes while the SPSunits charge fully (Figure 15).

Figure 15 DPE-AX system fault light and SPS recharge light

If any amber lights not related to the SPS recharging remain on after10 minutes, make sure the storage system is correctly cabled. Someamber lights may indicate a problem you can solve later, once yourstorage-system management software (Navisphere Express) is availableto help you troubleshoot the system.

If the power button on each SP does not remain solid/steady green,contact your authorized service provider.

If the power button on each SP remains solid/steady green, continueto the next section.


Connecting the storage-system management ports to the LAN

You manage the storage system from a Navisphere managementstation, which can be a host, a server (host connected to the storagesystem), or a Navisphere off-array management station with access tothe management ports over a specified LAN. In addition, when youfirst set up the storage system, you initialize it from a host, server, orNavisphere off-array management station connected to the same subnetas the storage-system management ports. The management ports arelocated on the rear of the chassis and labeled with a LAN symbol.

You cannot manage the storage system from the iSCSI data ports.

Cabling the storage-system management ports to the network

You need a standard CAT 5 or better Ethernet network cable for themanagement port on each storage-system SP.

On each SP connect one end of an Ethernet network cable to themanagement port on the SP and the other end to the network fromwhich you will manage the storage system (Figure 16).

Confirming hardware installation

Use Navisphere Express to check for hardware alerts before continuingthe installation process.

Starting Navisphere Express

1. Open an Internet browser, such as Internet Explorer, Netscape, orMozilla, on the management host.

2. Enter the IP address of an SP in the storage system.

This address is the one you assigned when you initialized the storagesystem.

If Navisphere Express does not open, make sure that the storagesystem is not rebooting. The power button on each SP should besolid/steady green and the other lights should be off.

3. Log in to Navisphere Express by entering the username andpassword that you specified when you initialized the storagesystem.

To view Navisphere Express in Brazilian Portuguese, French, German, Italian,Korean, Japanese, Latin American Spanish, or simplified Chinese, follow theinstructions in Adding a Navisphere Language Pack. You can create this documenton the storage-system support website by selecting Upgrade and then AddNavisphere Language Pack as the upgrade type. Once you install a languagepack, Navisphere Express automatically opens in that language.

Checking for hardware alerts with Navisphere Express

If the Navisphere Express page that opens after you log in contains anyhardware alerts, other than the email home or hot spare warnings,follow the instructions in the alert to fix the hardware problem beforecontinuing.


You will create one or more hot spares when you configure the storage systemlater in the installation process.


Initializing the storage system

After the storage system is fully powered up for the first time, use theNavisphere Storage System Initialization Utility to initialize the storagesystem. Initialization sets the network parameters for storage-systemmanagement and/or creates a management user account for the storagesystem so you can manage it over the LAN.

Before you start

To complete this procedure, you will need:

❑ The completed Administration Worksheet. This worksheet shippedwith your storage system. If you have not completed it, you shouldcomplete it now. This information includes:

A static IP address for each storage processor in the storagesystem (for example, http://123.45.6.7).

Static IP address for each SP in the storage system.

The subnet mask of the LAN to which the storage system isconnected.

The default gateway address of the LAN to which the storagesystem is connected.

❑ The storage-system serial number, which is the HW S/N numberlocated on the back of the DPE-AX (Figure 17).

Upgrading storage-system software

If you purchased the Expansion Pack, install the expansion packenabler now.

For optimal performance, the storage system should be running thelatest release of the FLARE® Operating Environment (OE). The versionnumber of this release is displayed on the storage-system supportwebsite. If the storage system is not running this version, install it now.

To display the FLARE OE version with Navisphere Express, in the navigationpane, select System and then Software.

Install the storage-system software with the software upgrade featureof Navisphere Express or the Software Assistant, which is part of theNavisphere Service Taskbar (NST). With Navisphere Express you caninstall only one software package (FLARE OE version, enabler, orlanguage pack) at a time. With the Software Assistant, you can installmultiple software packages (FLARE OE version, enabler, languagepack) at the same time; however, it requires a Windows host or serveron the same network as the storage-system management ports.

When to install a Navisphere language packA Navisphere language pack is updated only if the Navisphere userinterface (UI) changes in the FLARE OE. Typically the language pack isavailable after the English FLARE OE version is available. If you installFLARE OE with an updated Navisphere UI, then until you install thenew version of the language pack, text changes in the Navisphere UIare displayed in English and unchanged text continues to be displayedin the language, including the Navisphere Express help text. Toensure that all text changes and help changes in the Navisphere UI aredisplayed in the language, you should update the language pack assoon as the new version is available. To determine if the NavisphereUI changed in a new FLARE OE version, refer to the AX4-5 Integrated

Upgrading storage-system software with Navisphere Express

You can install only one software package (FLARE OE version, enabler,or language pack) at a time with the Navisphere Express upgradefeature.

Installing updated FLARE OE or a software enabler using Navisphere Express

! CAUTION

During the software installation procedure:

The storage system must not have any faulted or transitioningcomponents.

You can view the current state of storage-system components onthe Navipshere Express View Components page.

You must not power down or reboot the storage system, powerdown an SP, or remove any components. Doing so may put thestorage system in a state from which it cannot be restarted.

For a dual-SP system:

The software installation procedure reboots SP A, and then afterthe reboot of SP A completes, it reboots SP B. This causes anyconnected servers that are not configured for high availability(not connected to each SP) to lose access to the storage systemuntil the operation is completed.

1. If you are updating FLARE OE software, download the latestFLARE OE version from the CLARiiON® AX4-5 part of the“Downloads and Licensing” section of the Powerlink website(http://Powerlink.EMC.com) onto the host or server from whichyou will install the software.

This host or server must be on the same network as the storage-systemmanagement ports.


http://powerlink.emc.com

The FLARE OE software is in a .pbu file.

2. If you are installing an enabler:

a. Locate the enabler CD that shipped in the AX4-5 software orupgrade kit, and insert it into the CD drive on the host or serverfrom which you will install the software.

This host or server must be on the same network as the storage-systemmanagement ports.

b. Copy the enabler (.ena file) from the CD onto the host or server.

c. Remove the CD from the CD drive.

3. On the server or host with the FLARE version or enabler that youwant to install, start Navisphere Express for the storage system.

4. Wait until no storage-system components are in a transitioning statebefore continuing.

You can view the current state of storage-system components on theNavisphere Express View Components page.

5. In the navigation pane under System, click Software.

6. On the System Software page, click Upgrade Software.

Prior to installing the software on the storage system, NavisphereExpress performs a series of pre-installation checks to ensure thatthe storage system is in a ready state. If problems exist, the softwarewill ask you to fix them so it can continue the installation.

7. Either enter the path for the software .pbu or .ena file you justdownloaded or browse for it, and click Upgrade.

8. Monitor the status of the installation in the Software UpgradeStatus window.

After the installation is complete, the storage system rebootsautomatically. On a dual-SP system, one SP reboots, and when ithas finished, the other SP reboots. You cannot restart NavisphereExpress for the storage system, until the reboot is complete, whichcould take a couple minutes. When the reboot is complete, thepower button on each SP remains solid/steady green. When thestorage system reboots, you may see an error message, such as


39

Action Cancelled, in the browser. If you see an error message,close the browser, wait for the storage system to complete thereboot, and then reopen the browser and restart Navisphere Expressfor the storage system. If you do not see an error message, waituntil the reboot is complete before continuing.

Installing the Navisphere Server Utility

You must install the Navisphere Server Utility on each server connectedto the storage system. During the installation, if you do not disablethe Registration Service option (it is enabled by default), the serverutility automatically registers the server’s NICs or HBAs with thestorage system. You can also use the server utility to configure iSCSIconnections and mutual CHAP (optional), which you will do in a laterstep.

Before you start

To complete this procedure, you need the server support CD thatshipped with the storage system.

Installing the Navisphere Server Utility on a Windows server

IMPORTANT

To discover Microsoft iSCSI initiators on a Windows 64–bit operatingsystem, you must run version 6.28 or later (Windows Server 2008 hosts)or version 6.26 or later (Windows Server 2003 hosts) of the NavisphereServer Utility.

EMC recommends that you install the most recent version of theNavisphere Server Utility software that is appropriate for yourconfiguration. You can download the most recent version fromthe software download page on the Powerlink website or on thestorage-system support website. You can also install the software fromthe server support CD; however, the CD may not contain the mostrecent version for your configuration.

If you are running PowerPath 4.6 or later, you must install version 6.22.20 orlater of the Navisphere Server Utility.

Prior to version 6.22.20 of the server utility, you could not install bothapplications on the same server.

5. If you are prompted about updating information when the serverstarts, click Yes.

6. If you are prompted to reboot the server, click Yes.

You must reboot the server when the installation dialog prompts you toreboot. If the server is connected to the storage system with NICs and youdo not reboot before you run the server utility, the NIC initiators cannotlog in to the storage system.

7. When the installation is complete, click Done to exit the wizard.

8. If you installed the server utility from the CD, close the serversupport menu by selecting Main Menu and then Exit. You can nowremove the CD from the server’s CD drive.


Modifying TCP/IP registry settings

You can improve the performance of any NICs that will be usedprimarily for iSCSI traffic rather than general network traffic bychanging the network settings so that NICs immediately acknowledgeincoming TCP segments.

If you are running a version of the Navisphere Server Utility that isearlier than 6.24.1.4.0, we recommend that you manually modify theTCP/IP registry settings to improve performance; if the server is in aMicrosoft iSCSI cluster configuration, you must manually modify theTCP/IP settings for the server.

If you are running Navisphere Server Utility version 6.24.1.4.0 or later,the system prompts you to change these settings when you configurethe network parameters for your NICs (set up iSCSI connections).

! CAUTION

The following section contains information about modifying TCP/IPregistry settings. Before you modify the registry, make sure youback it up and understand how to restore the registry if a problemoccurs. For information about how to back up, restore, and edit theregistry, click the following link to the Microsoft Knowledge Base:http://support.microsoft.com/kb/256986/.

Connecting iSCSI ports in a network configuration

Use CAT5, CAT5e, or CAT 6 Ethernet network cables to connect thestorage-system iSCSI data ports to an Ethernet LAN and to connect theserver iSCSI data ports to either a 10/100 or 1-gigabit Ethernet LAN.

Before you start

To complete this procedure, you need:

❑ One Ethernet network cable per storage-system iSCSI port that youwill connect to the network. You need CAT 5 Ethernet networkcables for iSCSI connections to 10/100 LANs or CAT 6 cables foriSCSI connections to 1-gigabit LANs. These cables can be up to100 meters long.

❑ One Ethernet network cable per server iSCSI port that you willconnect to the network. You need CAT 5 Ethernet network cablesfor iSCSI connections to 10/100 LANs or CAT 6 cables for iSCSIconnections to 1-gigabit LANs. These cables can be up to 100meters long.

Connecting storage-system and server iSCSI ports to the LAN

1. For each iSCSI port on the storage system, connect one end of anEthernet network cable to the 0 iSCSI or 1 iSCSI port on the SP andthe other end to a router or switch (Figure 20).

2. For each NIC or iSCSI HBA port on the server, connect one end ofan Ethernet network cable (CAT 6 for 1-gigabit Ethernet network,CAT 5 for 10/100 LAN) to the iSCSI port on the NIC or iSCSI HBAand the other end to the network.


Configuring iSCSI initiators for a configuration without iSNS

If you are using iSNS, this section is not for you. Instead, go to sectionon configuring the iSNS client on the storage system.

Before an iSCSI initiator can send data to or receive data from thestorage system, you must configure the network parameters for theNIC or HBA iSCSI initiators to connect with the storage-system SPiSCSI targets.

Configuring NIC initiators on Windows servers to connect to the storage-system iSCSItargets without iSNS

Use the Navisphere Server Utility to configure the network parametersfor each NIC initiator that needs access to the storage system.

1. On the server, open the Navisphere Server Utility.

2. Select Configure iSCSI Connections on this server and click Next.

3. Select Configure iSCSI Connections and click Next.

4. In the iSCSI Targets and Connections window, select one ofthe following options to discover the iSCSI target ports on theconnected storage systems:

Discover iSCSI targets on this subnet - Scans the current subnetfor all connected iSCSI storage-system targets. The utility scansthe subnet in the range from 1 to 255. For example, if the currentsubnet is 10.12.77, the utility will scan the IP addresses from10.12.77.1 to 10.12.77.255.

If CHAP authentication is enabled on all target ports on a storagesystem, you cannot discover the iSCSI target ports using a subnet scan.You must discover the targets using the target portal.

Discover iSCSI targets for this target portal - Discovers targetsknown to the specified iSCSI SP data port.

5. Click Next.

6. For each target you want to log in to:

a. In the iSCSI Targets window, select the IP address of theInactive target.


67

b. Under Login Options, select Also login to peer iSCSI target forHigh Availability (recommended) if the peer iSCSI target islisted.

This option allows the utility to create a login connection tothe peer target so if the target you selected above becomesunavailable, data will continue to the peer target.

! CAUTION

If multiple NICs are on the same subnet and you leave theServer Network Adapter IP option set to Default, only oneNIC is actually used at a time. Other NICs are in standbymode. If you leave the Server Network Adapter IP option setto Default and a NIC fails, the server will use one of the otherNICs, even if they are on the same subnet, as long as thereis a network path from the storage system to the NIC that isin standby mode.

c. If you selected Also login to peer iSCSI target for HighAvailability (recommended) in the previous step, leave theServer Network Adapter IP set to Default to allow the iSCSIinitiator to automatically fail over to an available NIC in theevent of a failure.

If you are an advanced user and you want to control which networkor subnet is used, you can select a Server Network Adapter IP addressfrom the drop-down list but failover may not occur if you do not havethe appropriate failover software.

d. Click Logon to connect to the selected target.

7. Click Next.

One of the following windows is displayed:

Network Interfaces (NICs) window — This window is displayedif all of the following statements are true:

the NICs are on the same subnet as an iSCSI target connectedto this server.


the NICs appear to be used primarily for iSCSI traffic ratherthan general network traffic.

the NICs do not already have the recommended TCPsettings enabled.

This window allows you to update network settings on theselected NICs so that the NICs immediately acknowledgeincoming TCP segments.

Server registration window — This window is displayed andlists all connected storage systems if the above conditions arenot true.

8. If the Network Interfaces (NICs) window is displayed:

a. Uncheck any NICs that will be used for general network trafficand click Apply.

If a NIC is not listed and it is used primarily for iSCSI traffic, completethe remaining steps in this section and refer to the server utility’s onlinehelp for information on using the Optimize Network Interface (NICs)for iSCSI option. This option lists all the NICs on your server andallows you to manually select which NICs you want to immediatelyacknowledge incoming TCP segments for.

A confirmation dialog is displayed stating that the networksettings for your NICs have been updated but that you mustrestart your system to apply them.

b. Click OK and then Next.

9. In the server registration window, click Next to send the updatedinformation to the storage system.

A success message is displayed.

10. Click Finish to close the wizard.

Registering the server with the storage system

Run the Navisphere Server Utility on each server connected to thestorage system to register the server’s NICs or iSCSI HBAs with thestorage system.

Running the Navisphere Server Utility for Windows

You can run the Navisphere Server Utility for Windows from the server,if you installed the utility on the server, or from the server support CD,which shipped with the storage system.

Starting the Navisphere Server Utility on a Windows server

1. Run the Navisphere Server Utility by selecting Start > Programs> EMC > Navisphere > Navisphere Server Utility or Start > AllPrograms > EMC > Navisphere > Navisphere Server Utility.

2. Select your language, if prompted for it.

A text-based version of the utility is installed automatically when youinstall the utility. To start the text-based version, at a command promptenter cd C:\Program Files\EMC\Navisphere Server Utility or cdC:\Program Files (x86)\EMC\Navisphere Server Utility, then enterNaviServerUtilCLI.exe.

Starting the Navisphere Server Utility on a Windows server from the CD


2. In the server’s drive, insert the server support CD, which shippedwith the storage system or the upgrade kit (for upgrading AX4-5series or AX series systems to Navisphere Manager).

The server support menu opens. If you do not see the serversupport menu, open it:






3. From the main menu select Run Products from CD.

The RUN PRODUCTS page opens.

4. Select Navisphere Server Utility.

Registering the server using the Navisphere Server Utility on a Windows

1. In the Navisphere Server Utility dialog box, select Register thisserver to all connected storage systems.

The utility automatically scans for all connected storage systemsand lists them under Connected Storage Systems. Locate the WWNof the NIC or iSCSI HBA you just installed. The NIC or iSCSI HBAshould appear once for every SP port it is connected to.

If the utility is already running, it does not automatically perform a scan,and you must click Rescan.

2. Click Next to register the server with the storage system.

The utility sends the server’s name and IP address of the NIC oriSCSI HBA to each storage system. Once the server has storageon the storage system, the utility also sends the device name andvolume or file system information for each LUN (virtual disk) inthe storage system that the server sees.

3. Click Finish to exit the utility.

Verifying NIC or iSCSI HBA registration with Navisphere Express

1. In the navigation pane, under Manage, click Connections todisplay the Manage Connections page.

2. Verify that the SP/Port status is Active for each NIC or iSCSI HBAconnected to the storage system.

If the status is Active (unregistered), register the NIC oriSCSI HBA with the storage system by running the NavisphereServer Utility.


71

If the status is Inactive, either the physical connection betweenthe NIC or iSCSI HBA and the storage system is faulty or theserver is not powered up.


Configuring a new storage system

A new storage system is one that was not already connected to a serverwhen you started the installation procedure.

Before you start

You need the completed storage-system disk information worksheetfrom the storage-system configuration planning guide or the planningworksheets document. You can generate this guide using the Plan linkon the Install page of the storage-system support website or refer tothe appropriate planning guide on the documentation and resourcesCD, which shipped with the storage system.

Starting Navisphere Express

1. Open an Internet browser, such as Internet Explorer, Netscape, orMozilla, on the management host.

2. Enter the IP address of an SP in the storage system.


If Navisphere Express does not open, make sure that the storagesystem is not rebooting. The power button on each SP should besolid/steady green and the other lights should be off.

3. Log in to Navisphere Express by entering the username andpassword that you specified when you initialized the storagesystem.


73

To view Navisphere Express in Brazilian Portuguese, French, German, Italian,Korean, Japanese, Latin American Spanish, or simplified Chinese, follow theinstructions in Adding a Navisphere Language Pack. You can create this documenton the storage-system support website by selecting Upgrade and then AddNavisphere Language Pack as the upgrade type. Once you install a languagepack, Navisphere Express automatically opens in that language.

Configuring storage and event notification on a new storage system with NavisphereExpress

1. Locate your completed storage-system disk information worksheetso you can refer to it in the steps that follow.

2. Create one or more hot spares.

A hot spare is a single global spare disk that serves as a temporaryreplacement for any failed disk in the storage system. The storage systemautomatically reconstructs data from the failed disk onto the hot spare, sothe data is always available.

If you have both SAS and SATA disks in the storage system, we stronglyrecommend that you create a hot spare for each type of disk. A SAS diskcan be a hot spare for a SATA disk and vice versa, but using a SAS diskas a hot spare for a SATA disk will most likely degrade the disk poolperformance. Using a SATA disk as a hot spare for a SAS disk could wastedisk space since the SATA drives generally have greater storage capacity.

In the navigation pane, under Manage, click Hot Spare. For detailson creating a hot spare, use the Navisphere Express Help Center.

3. Create one or more disk pools on which to create virtual disks.


A disk pool is a set of disks, all with the same capacity and redundancy, onwhich you create one or more virtual disks. A RAID 6 disk pool usuallyhas 6 or 12 disks, but can have 4, 8, 10, 14, or 16 disks. RAID 6 disk poolsare supported only for AX4-5 series storage systems running FLARE OEversion 02.23.050.5.7xx or higher. A RAID 5 disk pool must include at leastthree disks, a RAID 3 disk pool must include five or nine disks, and a RAID1/0 disk must include at least two disks. The storage system supports amaximum of thirty disk pools.

In the navigation pane, under Manage, click Disk Pools. For detailson creating a disk pool, use the Navisphere Express Help Center.

For a dual-SP system, you should create at least two disk poolssince the software assigns each disk pool you create to an SP asfollows: disk pool 1 to SP A, disk pool 2 to SP B, disk pool 3 to SPA, and disk pool 4 to SP B. All the virtual disks you create on adisk pool are automatically assigned to the same SP as the diskpool, so if you create only one disk pool on the storage system, allvirtual disks on the storage system are assigned to SP A and all datareceived or sent goes through SP A only.

The disk modules marked 0 through 3 contain storage-system software orreserved space according to their slot assignment. Do not move any diskmarked 0 through 3 from its assigned slot. Remove it only to replace thedisk module. Part of the space on these disks is reserved or preloadedwith system data, and as a result, is not available for your data. If youcombine operating system disks in a disk pool with other disks, each of theother disks loses space for your data equal to the system data space onan operating system disk.

4. Create one or more virtual disks on each disk pool.

A virtual disk is a grouping of disk partitions into one span of disk storagespace. Each virtual disk you create is distributed equally across the disks inthe disk pool. A virtual disk looks like an individual disk to the server’soperating system. Each disk pool can have 128 virtual disks.

In the navigation pane, under Manage, click Virtual Disks. Fordetails on creating a virtual disk, use the Navisphere Express HelpCenter.

If you want to connect additional servers to the storage system, youcan create virtual disks for them now. However, you must waituntil the servers are connected and registered before you can assignthese virtual disks to them.

5. Assign one or more virtual disks to the server.

To send data to or receive data from the virtual disks, you must assignthe virtual disks to a server.

In the navigation pane, under Manage, click Virtual Disks. Fordetails on assigning a virtual disk to a server, use the NavisphereExpress Help Center.

6. Verify that the virtual disks were assigned to the server by viewingthe Manage Servers page.

In the navigation pane, under Manage, click Servers.

You should see the virtual disks you assigned to the server listed inthe Virtual Disks column of the server’s row.

7. Use the Event Notification page to configure the storage system tosend an email message when it encounters a problem.

In the navigation pane, under System, click Settings, and then clickEvent Notification. For details on configuring the storage systemto send email messages, use the Navisphere Express Help Center.

Verifying that each virtual disk is fully initialized using Navisphere Express

Although a new virtual disk is assigned to the server, the server cannotsee the new disk until it is fully initialized. The time to complete theinitialization process varies with the size of the virtual disk and otherparameters. For example, a 1 TB virtual disk in a RAID 5 disk pool of


11 disks can take about 70 minutes to initialize with no host I/O toother virtual disks in the disk pool.

To determine if any virtual disks are initializing:

1. Start Navisphere Express on the storage system with the virtualdisks.

2. In the navigation pane under Manage, click Virtual Disk.

3. In the Manage Virtual Disks screen, if the status of any virtual diskis Initializing, wait until the initialization is complete beforecontinuing.

4. If the virtual disk is connected to a server running Windows Server2003, reboot the server.

Making virtual disks visible to a Windows server

To allow the Windows server access to the virtual disks that youcreated, perform a rescan.

Verifying that PowerPath for Windows sees all paths to the virtual disks

1. On the server, configure PowerPath:

powermt config

2. On the Windows taskbar, either double-click the PowerPathAdministrator icon or right-click the icon and select PowerPathAdministrator.

3. In the results pane, verify that the path metric for each virtual diskis n/n where n is the total number of paths to the virtual disk.

Verifying your high-availability iSCSI configuration

Use the server high-availability feature in the Navisphere ServerUtility to verify the following for each server in a high-availabilityconfiguration with the storage system:

Your iSCSI configuration is highly available (for example, each NIChas at least one active path to each storage processor).

Path management software is installed and running on the server.

Starting the Navisphere Server Utility on a Windows server

1. Run the Navisphere Server Utility by selecting Start > Programs> EMC > Navisphere > Navisphere Server Utility or Start > AllPrograms > EMC > Navisphere > Navisphere Server Utility.

2. Select your language, if prompted for it.

A text-based version of the utility is installed automatically when youinstall the utility. To start the text-based version, at a command promptenter cd C:\Program Files\EMC\Navisphere Server Utility or cdC:\Program Files (x86)\EMC\Navisphere Server Utility, then enterNaviServerUtilCLI.exe.

Starting the Navisphere Server Utility on a Windows server from the CD


2. In the server’s drive, insert the server support CD, which shippedwith the storage system or the upgrade kit (for upgrading AX4-5series or AX series systems to Navisphere Manager).

The server support menu opens. If you do not see the serversupport menu, open it:






3. From the main menu select Run Products from CD.

The RUN PRODUCTS page opens.

4. Select Navisphere Server Utility.

Using the server utility to verify your high-availability configuration

1. In the Navisphere Server Utility dialog box, select Verify ServerHigh-Availability.

2. Select Valid Server Configuration only.

3. In the Select Host Type screen, select Local host and click Next.

4. In the Select Report Directory screen, select the location where thehigh availability status report should be saved. Click Next.

5. Read the summary and if it is accurate, click Next to generate thereport. If not, click Back to return to the screen where you needto correct the data.

The utility determines if the server is configured for high availabilityby verifying that the server has at least one connection path toeach storage system SP, and that PowerPath or some other failoversoftware, such as DMP, is running. It does not detect native failoversoftware, such as Windows Server 2008 native failover.

6. Review and resolve any issues reported under the Issues tab of thegenerated report before continuing with the installation process.

Preparing virtual disks to receive data

If you do not want to use a virtual disk as a raw disk or raw volume,then before Windows can send data to a virtual disk, you must:

❑ Use Navisphere Express to verify that each new virtual disk isinitialized and to write a signature to it.

❑ Either create partitions on a basic disk or create the appropriatevolumes on a dynamic disk, as described in the documentation foryour operating system version.

Saving the PowerPath configuration

Save the server’s PowerPath configuration with the followingPowerPath command: powermt save.

The powermt save command creates the powermt.customconfiguration file.


Verifying your failover configuration with PowerPath

Before you store data on virtual disks, use the procedure in this sectionto verify that:

The server can send data to and receive data from the storagesystem.

You can download an I/O simulator (Iometer) for writing data to thestorage system from the following website: http://www.iometer.org/.

PowerPath shows the paths from the server to the virtual disks thatyou expect for your configuration.

Verifying your failover configuration with PowerPath for a Windows server

1. Launch PowerPath Administrator by double-clicking thePowerPath Monitor on the Windows taskbar.

2. On the left pane (summary pane), click EMC PowerPathAdministrator.

3. Under the server, right-click Disks.

The right (details) pane lists all the virtual disks in each storagesystem connected to the server. Storage ID identifies each storagesystem. For each disk, the Path Status and the Path Metric columnsgive the status of the paths to the disk. When all n paths to a diskare working, the Path Status for the disk is optimal and the PathMetric for the disk is n/n, indicating that n of n paths are working.If only m paths are working, the path metric is m/n.

4. Verify that all n paths to the disks in the storage system areworking;‘ that is, their status is optimal and their path metric is n/n.

5. For each NIC or iSCSI HBA connected to the storage system:

a. Start writing data to a virtual disk.

b. Disconnect the cable from one NIC or iSCSI HBA connectedto the storage system.

c. After several seconds, look at the Details pane and verify thatone or more of the disks in the storage system have red slashes

http://www.iometer.org/

through them, their status is degraded, and their path metric ism/n, where n is the number of paths to the disk and m is thenumber of working paths, which is less than n. For example, ifthe server has 4 paths to a disk in the storage system and 1 pathfails when you disconnect the cable, then n=4 and m=3, so thepath metric is 3/4.

d. Reconnect the cable that you disconnected from the NIC oriSCSI HBA.

e. Right-click the PowerPath Monitor icon on the taskbar, andselect All Tasks and Restore All Devices.

f. After several seconds, look at the details pane and verify thatnone of the disks in the storage system have red slashes throughthem, their status is optimal, and their path metric is n/n.
