AX100-Series - Installing a Fibre Channel Storage System with a Switch Connection to a NetWare Server

Terminology

TerminologyThis document uses the terms new and existing to refer to storage systems, servers, and host bus adapters (HBAs) as follows:

The document also uses SP to refer to a storage processor in the storage system. An AX100SC storage system has only one SP, so it is called a single-SP storage system. An AX100 storage system has two SPs, so it is called a dual-SP storage system.

Existing HBA The host bus adapter (HBA) that is already installed in a server.

Existing server The server that is already configured for and connected to an AX-Series storage system.

Existing storage system An AX-Series storage system that is already connected to a server and configured for storage.

Host A computer that is or will be connected to an AX-Series storage system. This computer is called either a management host or a server, depending on how it is or will be connected to the storage system.

Management host A host from which you manage AX-Series storage systems. It must be on the same LAN as the storage-system management ports. A management host may also be server.

New HBA The HBA that was not already installed in the server.

New server A server that is not already connected to or set up for an AX-Series storage system.

New storage system A storage system that is not connected to a server or configured for storage. It is just as it was shipped to you.

Server A host that is already or will be connected through a switch to the Fibre channel ports on a AX-Series storage systems. A server can also be a management host.

Installing the Navisphere Server Utility

Installing the Navisphere Server UtilityRead this section for all configurations.

You must run the Navisphere Server Utility on each server connected to the storage system to register the server’s HBAs with the storage system. We recommend that you install it on each server also. If your AX-Series Server Support CD is version 1.1 or higher, you must install it if you want the server to access snapshots (copies of virtual disks) on the storage system.

Before You Start

To complete this procedure, you need the AX-Series Server Support CD that shipped with the storage system.

Install the Server Utility

1. Insert the AX-Series Server Support CD into the server’s CD drive, if it is not already inserted.

2. At a NetWare console, log in as a user with administrative privileges.

3. If DNS is functioning, verify that the IP addresses and names of your DNS servers are registered in the SYS:\ETC\RESOLV.CFG file.

If they are not registered, edit RESOLV.CFG to add the information.

4. On the NetWare server, verify that the SYS:\ETC\HOSTS contains an entry for the server itself, even if you will use DNS.

For example, if the IP address is 10.0.0.1 and the server name is server1, add 10.0.0.1 server1 to the NetWare server’s SYS:\ETC\HOSTS file. The host entry server1 identifies the host and will appear as the visible entry when you assign virtual disks to the server.


Installing the Navisphere Server Utility

5. Install the Navisphere Server Utility as follows:

a. From the NetWare client command prompt, change the directory to /NETWARE/NAVIHOST directory on the drive containing the CD.

For example:

cd D: /NETWARE/NAVIHOST

b. From the NetWare client command prompt, enter

INSTALL drive

where drive is the remote drive corresponding to the SYS volume on the NetWare server.

For example, INSTALL H: would cause the installation script to create the H:\EMC\NAVIHOST directory with all the required Navisphere Server Utility subdirectories.

6. Set the utility to restart automatically each time the server reboots:

a. On the NetWare server, enter

NWCONFIG

b. From the Installation Options menu, follow the path

NCF files options > Available NCF Files Options > Edit AUTOEXEC.NCF file

c. Add the following command to the end of the AUTOEXEC.NCF file:

LOAD SYS:\EMC\NAVIHOST\AXNAVHST UPDATE

d. Press ESC.

e. At the prompt to save the AUTOEXEC.NCF files, click Yes and press ESC twice.

f. At the prompt to exit the install process, click Yes.

7. Remove the CD from the CD drive.

Installing Additional Disks

Installing Additional DisksRead this section if you received any disks that are not already installed in the storage system.

Handling FRUs

This section describes the precautions that you must take and the general procedures you must follow when removing, installing, and storing disk drive modules or any other Field Replaceable Unit (FRU).

Power Issues and FRUsThe storage system is designed to be powered up continually and hot repairable. Front bezels should be attached and each compartment should contain a FRU or filler panel to ensure EMI compliance and proper air flow over the FRUs.

You should not remove a faulty FRU until you have a replacement available.

When you replace or install FRUs, you can inadvertently damage the sensitive electronic circuits in the equipment by simply touching them. Electrostatic charge that has accumulated on your body discharges through the circuits. If the air in the work area is very dry, running a humidifier in the work area will help decrease the risk of ESD damage. Follow the procedures below to prevent damage to the equipment.

Read and understand the following instructions:

◆ Provide enough room to work on the equipment. Clear the work site of any unnecessary materials or materials that naturally build up electrostatic charge, such as foam packaging, foam cups, cellophane wrappers, and similar items.

◆ Do not remove replacement or upgrade FRUs from their antistatic packaging until you are ready to install them.

◆ Before you service a storage system, gather together the ESD kit and all other materials you will need. Once servicing begins, avoid moving away from the work site; otherwise, you may build up an electrostatic charge.


24


◆ An ESD wristband is supplied with your storage system. To use it, attach the clip of the ESD wristband (strap) to any bare (unpainted) metal on the storage system; then put the wristband around your wrist with the metal button against your skin.

◆ Use the ESD kit when handling any FRU. If an emergency arises and the ESD kit is not available, follow the procedures in the Emergency Procedures (Without an ESD Kit) section.

Emergency Procedures (Without an ESD Kit) In an emergency when an ESD kit is not available, use the following procedures to reduce the possibility of an electrostatic discharge by ensuring that your body and the subassembly are at the same electrostatic potential.

These procedures are not a substitute for the use of an ESD kit. Follow them only in the event of an emergency.

◆ Before touching any FRU, touch a bare (unpainted) metal surface of the cabinet or storage system.

◆ Before removing any FRU from its antistatic bag, place one hand firmly on a bare metal surface of the storage system, and at the same time, pick up the FRU while it is still sealed in the antistatic bag. Once you have done this, do not move around the room or touch other furnishings, personnel, or surfaces until you have installed the FRU.

◆ When you remove a FRU from the antistatic bag, avoid touching any electronic components and circuits on it.

◆ If you must move around the room or touch other surfaces before installing a FRU, first place the FRU back in the antistatic bag. When you are ready again to install the FRU, repeat these procedures.



Add Disk Modules

CAUTION!Disk modules are extremely sensitive electronic components. Always handle a disk module gently, and observe the following guidelines:

◆ Always replace a disk module with another of the same model. Contact your sales/service representative for a list of approved disk replacements.

◆ Follow the instructions in the preceding section, Handling FRUs (page 23).

◆ Always wear a properly attached ESD wristband when removing or replacing a disk module.

◆ Place modules on a soft, antistatic surface, such as an industry-standard antistatic foam pad or the container used to ship the module. Never place a disk module directly on a hard surface.

◆ Never hit modules, stack modules, or allow them to tip over or fall.

◆ Avoid touching any exposed electronic components and circuits on the disk module.

You must remove the storage system’s front bezel to gain access to the disk modules. The bezel is required for EMI compliance when the storage system is powered up. Remove it only to replace or add a disk module.


26


Unlock and Remove the Front Bezel Follow these steps to remove the front bezel and gain access to the disk modules (Figure 7).

1. Insert the key that shipped with your storage system into the bezel lock, and turn it to release the lock.

2. Press the two latch buttons on the bezel surface toward each other to release the bezel from the cabinet.

3. Pull the bezel off the cabinet and put it on a clean, static-free surface.

If You Need to Power Down the Storage SystemFor an orderly shutdown that protects your cache data, use the storage-system power button. The storage system takes a full minute to power down after you press the power button. So after powering down the storage system, wait one minute before powering it on again. If storage-system power is turned off by the power button or by a software shutdown, you must press the power button to re-apply power. If you power down the storage system by unplugging the power cord, the storage system powers up as soon as it is reconnected to the ac power source.

What Next? Go to Connecting the Storage-System and Switch Management Ports (page 42).


Connecting ac Power to an AX100 Storage System

Connecting ac Power to an AX100 Storage SystemRead this section if you are connecting power to anAX100 (dual-SP) storage system. If you are connecting power to an AX100SC (single-SP) storage system, go to Connecting ac Power to an AX100SC Storage System (page 33).

Before You Start

To complete this procedure, you need❑ The serial cable that shipped with the UPS. This cable allows

Navisphere Express to monitor UPS status. You may also need an RJ45-DB9 adapter cable that shipped in the AX100-Series accessory box to connect the UPS serial cable to the storage system.

❑ The ac power cables appropriate to your power source. These cables shipped with the storage system.

Connect the UPS Serial Cable to the AX100 Storage System

CAUTION!Be sure to use the unique serial cable supplied with your UPS; a standard null-modem or other service serial cable may look identical, but will not work. You may need to attach an adapter cable to connect the UPS serial cable to the AX100 UPS port.

If the UPS serial cable has two DB9 connectors:

1. Locate an RJ45-DB9 adapter cable in the AX100-Series accessory box.

2. Plug the adapter cable into the UPS serial cable.

3. Plug the free end of the UPS serial cable into the serial port on the UPS (Figure 17).

4. Plug the free end of the adapter cable into the UPS connector (labeled with a +- battery icon) on SP A (Figure 17).


38


If the UPS serial cable has one DB9 and one RJ45 connector:

1. Plug one end of the UPS serial cable into the serial port on the UPS (Figure 17).

2. Plug the free end of the UPS serial cable into UPS connector (labeled with a +- battery icon) on SP A (Figure 17).

Connect ac Power to the AX100 Storage SystemAs you perform this procedure, refer to Figure 17.

CAUTION!Do not connect the power cord to an ac power source until the storage system, the UPS, and the switches are installed in the cabinet. The storage system powers up as soon as it is connected to an ac source.

1. Plug a storage-system power cord into the power connector on both power supplies in the storage system.

2. Secure each power cord with the retention bail at the connector.The retention bail prevents the power cord from pulling out of the connector and causing the storage system to power down unexpectedly.

3. Plug each storage-system power cord into an ac power source as follows:

Do not connect more than one power supply to the UPS.

a. Plug the storage-system power cord connected to the SP A power supply into the power outlet on the UPS.

b. For a 100V or 120V UPS, plug the attached UPS power cord into an ac power source.

c. For a 230V UPS, plug one end of the loose UPS power cord into the UPS power outlet and the other end into an ac power source in the cabinet (power distribution unit).

d. Plug the power cord connected to the SP B power supply into the ac power source in the cabinet (power distribution unit).

Do not connect the SP B power supply to the same power source/circuit as the UPS.

Connecting the Storage-System and Switch Management Ports

Connecting the Storage-System and Switch Management PortsRead this section if you are installing a new storage system.

You manage the storage system from a management host, which can be a server that has access to the management ports over a specified 10/100 LAN. In addition, when you first set up the storage system, you must initialize it from a host, which can be a server, connected to the same network subnet as the storage-system management ports. The management ports are located on the rear of the chassis and labeled 10/100.

You manage the switch from a host connected to the same network as the switch.

Before You Start

To complete this procedure, you need a standard CAT 5 or higher LAN cable for

❑ Each management port on each storage-system SP that you will connect to the 10/100 LAN

❑ Each switch if you want to manage the switch with the switch vendor’s management software.

Be sure you do not connect the LAN cable to the serial or UPS ports.

Cable the Storage-System and Switch Management Ports to the Network

1. For each SP, connect one end of a LAN cable to the 10/100 management port on the SP and the other end to the network from which you will manage the storage system (Figure 19).

Be sure you do not connect the LAN cable to the serial or UPS ports.



Figure 19 Storage-System LAN Connections (AX100 Shown)

2. If you want to use the switch management software, connect one end of a LAN cable to the LAN management port on each switch and the other end to the network from which you will manage the switch (Figure 20).

Connecting Switches to the Storage System and Server

Connecting Switches to the Storage System and ServerRead this section for all configurations.

Use optical cables to connect switch ports to storage-system Fibre Channel ports (labeled FE 0 and FE 1 on each SP) and to server HBA ports.

Before You StartTo complete this procedure, you need an optical cable for each SP port you will use on the storage system and each switch port you will use. For cable specifications, refer to Technical Specifications in the "Technical descriptions" section on the AX100 support website.

Handling Optical CablesOptical cables are susceptible to damage, so take the following precautions when handling them:

◆ Keep the covers on all optical cables until you are ready to insert them.

◆ Avoid tight bends. If you need to make a 90º bend, do it over 6 to 12 inches.

◆ Do not use optical cables to support weight (including their own, unsupported weight if they are long).

◆ Do not pull long runs of cable; instead, lay the cable in place or pull only a few feet at a time.

◆ Place the cables where no one can step on them or roll equipment over them.



Cable the Switch to the Storage SystemOn the customer-installable switch, use ports 0 and 4 only for SP connection and ports 1-3 and 5-7 only for HBA connections. The switch is preconfigured so that any SP connected to ports 0 or 4 communicates with any HBA connected to ports 1-3 and 5-7.

For highest availability with a multiple-HBA server

◆ Single-SP system - Connect FE 0 to port switch 0 and FE 1 to switch port 4.

◆ Dual-SP system - Connect either FE port on SP A to switch port 0 and either FE port on SP B to switch port 4.

As you perform the procedure below, refer to Figure 26.

1. Remove the protective cover from the optical connector on switch port 0 or switch port 4 and from one end of the optical cable, and plug the cable into the switch port.

2. Remove the protective covers from the FE connector on the SP and from the free end of the optical cable, and plug the cable into the FE connector.

3. For each additional FE port you want to connect to the switch, repeat steps 1 and 2.

Registering the Server with the Storage System

Registering the Server with the Storage SystemRead this section for all configurations.

You must run the Navisphere Server Utility on each server connected to the storage system to register the server’s HBAs with the storage system.

Run the Server Utility to Register the Storage System with the Server

1. At a NetWare console, log in as a user with administrative privileges.

2. From the NetWare console enter

LOAD SYS:\EMC\NAVIHOST\AXNAVHST

If the server utility does not start, the storage system may still be rebooting. When the reboot is complete, the SP Boot/Fault light on the back of each SP is off and not blinking. If the reboot is complete, try running the utility again. If the utility still does not start, you may have an early version of AX Server Utility. Try starting it by entering LOAD SYS:\EMC\NAVIHOST\NAVIHOST.

3. In the Server Utility, enter 1 to select Update Server Information.

The utility automatically scans for connected AX100-Series storage systems, and displays a list of the ones it finds.

4. In the Server Utility, enter u to register the server with each storage system the utility found.

Start Navisphere Express1. Open an Internet browser, such as Internet Explorer or Netscape,

on the server or on any host on the same LAN as the storage system.


The IP address is one you assigned when you initialized the storage system (from the Storage-Management Ports section of the planning guide).



3. Log in to Navisphere Express by entering the username and password.

The username and password are the ones that you specified when you initialized the storage system (from the Storage-Management Ports section of the planning guide).



Verify HBA Registration1. In the Navisphere Express navigation pane, under Manage, click

Connections to display the Manage Connections page.

2. Verify that the SP/Port status is Active for each HBA connected to the storage system.

• If the status is Active (unregistered), register the HBA with the storage system by running the Navisphere Server Utility as described in Registering the Server with the Storage System (page 59).

• If the status is Inactive, either the physical connection between the HBA and the storage system is faulty or the storage system is not powered up. Go to the "Troubleshoot" section on the AX100 support website or the AX100-Series Documentation CD.

What Next? For a new storage system, continue to the next section, Configuring a New Storage System (page 62).

For an existing storage system, go to Configuring an Existing Storage System (page 66).


62

Configuring a New Storage System

Configuring a New Storage SystemRead this section if you are configuring a new AX100SC or AX100 storage system. A new storage system is one that was not already connected to a server when you started the installation procedure.

Before You Start

You need to complete the configuration planning worksheets from Planning Your AX100-Series Fibre Channel Storage-System Configuration in the "Plan" section on the AX100 support website or the AX100-Series Documentation CD.

Start Navisphere Express If It Is Not Already Running

1. Open an Internet browser, such as Internet Explorer or Netscape, on the server or on any host on the same LAN as the storage system.








Configure a New Storage System1. Locate your completed storage-system configuration planning

worksheet so you can refer to it in the steps that follow.

2. Create a hot spare.

A hot spare is a single global spare disk that serves as a temporary replacement for any failed disk in the storage system. The storage system automatically reconstructs data from the failed disk onto the hot spare, so the data is always available.

To create a hot spare - in the Navisphere Express navigation pane, under Manage, click Hot Spare. For details on 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, on which you create one or more virtual disks. A RAID 5 disk pool must include at least three disks and a RAID 1/0 must include at least two disks. The storage system supports a maximum of six disk pools.

To create a disk pool - In the Navisphere Express navigation pane, under Manage, click Disk Pools. For details on creating a disk pool, use the Navisphere Express Help Center.

For an AX100 (dual-SP) storage system, you should create at least two disk pools, since the software assigns each disk pool you create to an SP as follows: disk pool 1 to SP A, disk pool 2 to SP B, disk pool 3 to SP A, and disk pool 4 to SP B. All the virtual disks you create on a disk pool are automatically assigned to the same SP as the disk pool, so if you create only one disk pool on an AX100 storage system, all virtual disks on the storage system are assigned to SP A and all data received or sent goes through SP A only.

The disk modules marked 0 through 3 contain storage-system software or reserved space according to their slot assignment. Do not move any disk marked 0 through 3 from its assigned slot. Remove it only to replace the disk module. Part of the space on these disks is reserved or preloaded with system data, and as a result, is not available for your data. If you combine


64


operating system disks in a disk pool with other disks, each of the other disks loses space for your data equal to the system data space on an operating system disk.

4. Create one or more virtual disks on the disk pools.

A virtual disk is a grouping of disk partitions into one span of disk storage space. Each virtual disk you create is distributed equally across the disks in the disk pool. A virtual disk looks like an individual disk to the server's operating system. Each disk pool supports 128 virtual disks.

To create a virtual disk, in the Navisphere Express navigation pane, under Manage, click Virtual Disks. For details on creating a virtual disk, use the Navisphere Express Help Center.

If you want to connect additional servers to the storage system, you can create virtual disks for them now. You have to wait until the servers are connected and registered before you can assign these 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 assign the virtual disks to a server.

To assign a virtual disk to a server - In the Navisphere Express navigation pane, under Manage, click Virtual Disks.

For details on assigning a virtual disk to a server, use the Navisphere Express Help Center.

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

To display the Manage Servers page - In the Navisphere Express navigation pane, under Manage, click Servers.

Configuring an Existing Storage System

Configuring an Existing Storage SystemRead this section if you are configuring an existing AX100SC or AX100 storage system. An existing storage system is one that was already connected to a server when you started the installation procedure.

Before You Start

You need to complete the configuration planning worksheets from Planning Your AX100-Series Fibre Channel Storage-System Configuration in the "Plan" section on the AX100 support website or the AX100-Series Documentation CD.

Start Navisphere Express If It Is Not Already Running

1. Open an Internet browser, such as Internet Explorer or Netscape, on the server or on any host on the same LAN as the storage system.








Configure an Existing Storage System1. Locate your completed storage-system configuration planning

worksheet so you can refer to it in the steps that follow.

2. If you need additional disk pools for virtual disks for the server, create one or more disk pools.

A disk pool is a set of disks, all with the same capacity and redundancy, on which you create one or more virtual disks. A RAID 5 disk pool must include at least three disks and a RAID 1/0 must include at least two disks. The storage system supports a maximum of six disk pools.

To create a disk pool - In the Navisphere Express navigation pane, under Manage, click Disk Pools. For details on creating a disk pool, use the Navisphere Express Help Center.

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

3. If you need additional virtual disks for the server, create one or more virtual disks on the disk pools.

Each disk pool supports a maximum of 128 virtual disks.

To create a virtual disk - In the Navisphere Express navigation pane, under Manage, click Virtual Disks. For details on creating a virtual disk, use the Navisphere Express Help Center.

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

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

To assign a virtual disk to a server - In the Navisphere Express navigation pane, under Manage, click Virtual Disks.

For details on assigning a virtual disk to a server, use the Navisphere Express Help Center.

5. Verify that the virtual disks were assigned to the server by looking at the Manage Servers page.

To display the Manage Servers page - In the Navisphere Express navigation pane, under Manage, click Servers.

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

If you do not see virtual disks, go to the "Troubleshoot" section on the AX100 support website or the AX100-Series Documentation CD.

6. Configure PowerPath:

/etc/opt/emcpower/powercf -qpowermt config

7. On the server, verify that PowerPath sees all the paths to the virtual disks with the PowerPath command:


What Next? Go to Preparing Virtual Disks to Receive Data (page 69).


Preparing Virtual Disks to Receive Data

Preparing Virtual Disks to Receive DataRead this section for all configurations.

Before NetWare can access a virtual disk, you must create a partition and volume on it.

Create and Mount NWFS Partitions and Volumes on Virtual Disks

NetWare Cluster Service requires NSS (not NWFS) partitions and volumes. To create NSS partitions and volumes, go to Create NetWare NSS Partitions on Virtual Disks (page 71).

Create NetWare NWFS Partitions on Virtual Disks1. Before continuing, make sure the virtual disks you created are

completely (100 percent) initialized.

a. Start Navisphere Express.

b. In the Navisphere Express navigation pane under Manage, click Virtual Disk.

6. From the Select a Managed Object menu, select the NSS partition where you want to create the NSS volume.

7. Enter the name of the NSS volume.

8. Select Yes to confirm your decision.

9. For each partition you created in the previous section, create a volume as in steps 4 through 8.

10. When you finish creating volumes, press ESC repeatedly until the Configuration Options menu appears. Then exit the NWCONFIG utility.

11. At the NetWare server command prompt, for each volume you want to mount, enter the mount command:

mount volume_name

where volume_name is the name you specified in step 7.

The server can now write data to and read from the volumes.

Save the PowerPath Configuration

Save the server’s PowerPath configuration:

powermt save

This command creates the powermt.ctm configuration file.


Sending NetWare Disk Information to the Storage System

Sending NetWare Disk Information to the Storage SystemRead this section for all configurations.

You must rerun the Navisphere Server Utility to send to the storage system the NetWare device name and volume or file system information for each virtual disk that the server sees. Navisphere Express displays this information on its Details page for each virtual disk.

Start the Server Utility

From the NetWare console enter

LOAD SYS:\EMC\NAVIHOST\AXNAVHST

If the server utility does not start, the storage system may still be rebooting. When the reboot is complete, the SP Boot/Fault light on the back of each SP is off and not blinking. If the reboot is complete, try running the utility again. If the utility still does not start, you may have an early version of the AX Server Utility. Try starting it by entering LOAD SYS:\EMC\NAVIHOST\NAVIHOST.

The utility automatically scans for connected AX100-Series storage systems, and displays a list of the ones it finds.

Register the Server with the Storage System

In the Server Utility, enter u to register the server with each storage system the utility found.

The utility sends to each storage system the server’s name and IP address and the NetWare device name and volume or file system information for each virtual disk in the storage system that the server sees.


74

Verifying Your Configuration

Verify That the Storage System Received the Disk Information1. For each virtual disk in the storage system that is connected to the

server, display its Navisphere Express Details page:

a. In the Navisphere Express navigation panel, under Manage, click Virtual Disks.

b. On the Manage Virtual Disk page, click the virtual disk to display its Details page.

2. Verify that the Details page displays the volume or file system and device name for the virtual disk.

Verifying Your ConfigurationRead this section for all configurations.

Before you store data on virtual disks, you should use the procedure below to verify that:

◆ The server can send data to the storage system.

◆ PowerPath shows the paths from the server to the virtual disk that you expect for your configuration.

Before You StartIf you are not familiar with PowerPath, read PowerPath in Action in the "Technical descriptions" section on the AX100 support website or the AX100-Series Documentation CD.



Verify Your Configuration with PowerPath1. Save the server’s PowerPath configuration with the following

PowerPath command:powermt save

This command creates the powermt.ctm configuration file.

2. If you connected a new server to an existing storage system, stop all applications accessing the storage system and disable user logins to the server.

3. View the virtual disks available to the server:


4. Choose one available virtual disk to receive data (I/O) for the test.

5. View the paths to the chosen virtual disk:

powermt display dev=x every=2

where x is a pseudo device that represents the chosen virtual disk.

6. Start sending data to a virtual disk by writing data to it.

7. Identify the HBA sending data to the virtual disk by viewing the output of the powermt display dev=x every=2 command, and disconnect the cable to that HBA.

8. View the output of the powermt display dev=x every=2 command, and verify that:

• The state of the uncabled paths becomes “dead.”

• Data continues to be sent on the remaining path(s) to the virtual disk, indicating that the failover path was successful and that PowerPath is working properly.

If PowerPath is not working properly, refer to the "Troubleshoot" section on the AX100 support website or the AX100-Series Documentation CD.

9. Reconnect the cable that you disconnected from the HBA.

10. If you caused any virtual disks to fail over, restore the disks to their original SP:powermt restore

11. For each HBA connected to the storage system, repeat steps 3 through 10.
