Lab Description

Purpose:

This lab is designed to familiarize the user with the configuration and management of a CLARiiON Storage System using the Navisphere Manager Graphical User Interface (GUI). The Navisphere Manager GUI is very robust in its ability to provide the necessary information for day-to-day management of a CLARiiON data storage environment, while providing an easy to use, Windows look and feel. This lab will walk the user through the steps necessary to create and allocate data storage on a CLARiiON Storage System as well as acquaint the user with optional CLARiiON software that allows for disaster recovery and staging data for online data backups.

This lab provides step-by-step directions for configuring a CLARiiON using Navisphere Manager 6.x. The revision of Navisphere Simulator is based on Release 26 of CLARiiON base code.

Note the Simulator does not contain the entire features/function set like the real Navisphere Manager product. If at any time the Simulator appears frozen or non responsive, exit the application and Launch it again.

1. This simulator supports only version JRE 1.6.x. If no JRE is present the Simulator will install one automatically when user opens the application for first time

2. Reporting wizard will create the html reports under c:\. 3. A Reset option has been provided in the Simulator once installed. It appears in the menu item like this

4. Uninstall option is also included in Simulator as shown above. 5. The read me text file is in the install folder for support of JRE 1.6.x 6. Help file has been updated to reflect all wizard modules.




Objectives: Upon completion of this course, you will be able to: • Configure RAID Groups on a CLARiiON Storage System • Bind LUNs to RAID Groups on a CLARiiON Storage

System • Configure Storage Groups on a CLARiiON Storage System • Configure Snapshots • Create Clones • Create SANCopy Full and Incremental Sessions • Create MirrorView Synchronous and Asynchronous Images• Expand a LUN to create metaLUNs • Migrate a LUN to another LUN

References: The following tools/aids/materials are required to perform the steps in this lab:

• 1 - laptop or desktop computer running either Windows NT or Windows 2003 operating system

• 1 – Copy of the Navisphere Manager Simulator software (CD or download) installed on the computer

• 1 – Copy of this Lab Document

• Internet Explorer v6.x installed on service laptop or management workstation

• Java Runtime Environment 1.6.x (will be installed if not on the computer)

• Optional - Navisphere 6.x Manager User Guide (explains some of the parameters not used in these exercises)


Lab 1: Logging into the Navisphere Manager Navisphere Manager requires a valid username and password to log in on the Manager Graphical User Interface (GUI). This is to authenticate the user and determine his authorization level for management and configuration of the CLARiiON Storage Environment.

Step Action

1. Start the Navisphere Manager interface by choosing Start > Programs > Navisphere Simulation > Launch Navisphere Simulator

2. Click “OK” at the login screen ( Username: administrator and Password: emc ) 3. The lab assumes there are no RAID Groups, Storage Groups, or other objects created at this time.

4. The lower left window should display the credentials you logged in with.



Lab 2: Navigating the Navisphere Manager User Interface Use these steps to learn how to navigate the Navisphere Manager User Interface (UI) software. You will be asked to navigate the Enterprise Storage window by expanding the objects that represent logical and physical components on the CLARiiON Storage Systems.

Step Action

1. Expand the objects where you see a “+” sign. The TASK Bar shown at the left allows the user to perform common functions such as Binds, Mirrors, and Snap creation. It brings up a Wizard to guide the user through basic configuration tasks. The Reserved LUN Pool is free, and the Physical container shows a number of DAE3P and components in the rack. The LUN Folders container allows a way to easily organize LUNs in the array. Note again at this time there are no RAID Groups, Storage Groups, and LUNs.



2. By expanding the Physical Container you can view the DAE3P enclosures. Each DAE3P can

contain up to 15 FC or SATA disk drives. Note also the other components such as FANs, LCC’s, and Power Supplies, and SPs.

3 3. Expand the Enclosure SPE container. Storage Processor Enclosures contain their own Power

Supplies, Fans, as well as Front ( Host side ) and Backend (disk side ) ports. Take a moment to examine the WWPNs. What speed are the Backend ports running?

4. Practice expanding and shrinking objects on the selected array.

5. Click on the Tools > Security tab from the toolbar and examine the options available.

14.




Lab 6: Configuring SnapView Snapshots

Step Action

1. A snapshot is a virtual LUN that when activated, allows a secondary server to view a point-in-time copy of a source LUN. An active snapshot is a composite of a source LUN and reserved LUN data that lasts until you destroy the snapshot. Each snapshot is linked to a source LUN(s). If the storage system loses power while the SnapView session is running and you have an AX-series system or are running SnapView version 6.24 or later, both the session and snapshot would survive the storage system power failure, since all sessions run in persistent mode. If you have an earlier version of SnapView and did not start your session in persistent mode, the session is lost and the snapshot becomes inactive.

Writes to an active snapshot from a secondary server are stored in the reserved LUN pool until the snapshot is deactivated. When a secondary server deactivates the snapshot, the software destroys all writes made to the snapshot.

The exercise will have you create and remove Snapshots on a CLARiiON array.

2. Click on Replication Tab from the Task Bar

From the Snapshot container try to destroy the snapshot again. Did it work?

7. End of Exercise



Lab 7: Configuring SnapView Clones A clone is a complete copy of a source LUN. You specify a source LUN when you create a clone group. The copy of the source LUN begins when you add a clone LUN to the clone group. The software assigns each clone a clone ID. This ID remains with the clone until you remove the clone from its group. While the clone is part of the clone group and unfractured, any production write requests made to the source LUN are simultaneously copied to the clone. Once the clone contains the desired data, you can fracture the clone. Fracturing the clone separates it from its source LUN, after which you can make it available to a secondary server. The next steps will take you through the creation of Clones using the Wizard.

Step Action

1. From SG_w3k-240, right click on LUN 0 , Click Apply, Yes, OK

From the Task Bar Wizard, Click Configure SnapView Clones Icon

Select Next from the Welcome screen

Are they different and RAID Types and sizes? Were there any LUNs from RG 1 Why Not? Select LUN 20, take the defaults, click Apply, Yes, OK , Cancel Examine the Clone Group again. Note the RAID Types that make up the Clone group. What does this tell you about adding a Clone?



4. Right click on Clone 010000.. and select Fracture

Note the status change on both Clones

Right click again in the LUN and select “Synchronize”

5. Right Click on the Clone group name and select Destroy Clone Group. Did you receive a message? Right click on the Clone ( 010000…. ) and select remove. Do this for both clones. Right click on the Clone group name again and select Destroy Clone Group.

6. End of Exercise


Lab 8: San Copy Full Replicas Step Action

1. San Copy will copy data to LUNS on the same array or between 2 arrays over distance.

San Copy uses CLARiiON ports that are zoned together to make a San Copy Connection. LUNs on both arrays should appear in the Storage Groups that have the San Copy connections setup.

ON CX3-40-BOTTOM > Storage Group SG_w3-241 2. In your connection window, note the “SAN Copy Connection” box. It should show the remote array and an SP.

The box from “Ports to Connect” will show ports that are properly zoned. You can select a different System by using the drop down arrow next to it. For each port that is unchecked, CHECK it, then APPLY. Repeat this for ALL ports. Use the drop down and check the other ports. You should have connections to 2 ports on the remote array. Expand the San Copy Connections to validate.

5. Completed session.

Remove all San Copy sessions

Right click on each session and click REMOVE. Validate all session are gone.



Lab 10: Creating Synchronous Mirrors A remote mirror consists of a primary image and up to two secondary images. The production image (the one mirrored) is called the primary image; the copy image is called the secondary image. MirrorView/S supports up to two remote images. Each image resides on a separate storage system. The primary image receives I/O from a server called the production server; a separate storage system maintains the secondary image. This storage system can optionally have a failover/standby computer connected to it or can be connected to its own computer system. Both storage systems can be in different domains, which you manage with the User Interface (UI). The client that is managing the storage system containing the primary images can fail over to the secondary image if the primary image becomes inaccessible. In the previous labs, you created RAID Groups, Storage Groups attached hosts, and created Clones and Snaps. CLARiiONs arrays support two (2) types of mirrors - Synchronous and Asynchronous. The creation of RAID Groups Storage Groups and LUNs should have already been done on BOTH ARRAYS.

Step Action

1. Right click on the CX3-40_Top array > MirrorView > Manage MirrorView Connections

Select the connection from the right panel and click Enable . Click OK

Open Storage group w3k-240 on CX3-40-Top array. Right click on LUN 0 > Properties> Rename the LUN 0 to MVS_Source_LUN 0

Click on the configure MirrorView Icon from the Task Bar

Click Next from the welcome screen




From the Select Servers screen , Highlight w3k-240, Click Next

Select cx3-40-TOP from the Select Primary Storage Screen, Click Next

From the Select Storage LUN Screen, Expand Storage Group w3k-240

Check the box for MVS_Source_LUN 0 ,Click Next

From the Select Secondary Storage System , Select cx3-40-BOTTOM, Click Next

From the Select Mirror Type window, read the dialog for the Mirror types

Choose the radio button for Synchronous, Click Next

From the Attribute screen Click Next

From the Configuration screen select Next

From the RAID Configuration screen Take the defaults, Click Next

From the Select Servers Screen, leave the defaults and Select w3-241. Click Next

Read the Summary Screen Click finish

Read the Results Screen click Finish 2. Expand and examine the following containers on the Primary ( cx3-40-top) and Secondary (cx3-40-BOTTOM)

arrays

Private LUNs under LUN Folders

SPs

Storage Groups

Remote Mirrors Note: The write intent log keeps track of writes that have not yet been made to the remote image for the mirror. It allows for fast recovery when the primary storage system fails. When the primary fails and is recovered, the write intent log is used to synchronize the data on the remote image. Otherwise, a full resynchronization would be required for the remote image. In situations where you must replace the primary storage system due to a catastrophic failure, you can use a promotion to access data on the secondary storage system. To recover and restore I/O access, you must promote a secondary mirror image to the role of primary mirror image, so that a server can access it.

3. On the Primary array open the Remote Mirrors container and expand out all options. Right click on the Secondary Image name and note the options. Click Promote, read the next 2 screen. Did the Primary and Secondary Mirrors switch states? Try promoting the Primary image Promote the secondary image back to Primary Right click on the secondary image and Fracture the mirror. Did the state change? Right click on the secondary image and “Remove” it Right click on the Mirror Name and Destroy the Mirror.

4. End of Exercise



Lab 11: Creating Asynchronous Mirrors Step Action

1. Creating an Asynchronous Mirror is very similar to a Synchronous Mirror.

Open SG_W3k-240 Storage Group. Right click on LUN 1, Rename LUN 1 to MVA_Source_LUN 1

Use the same procedures you used to create a synchronous mirror except select “Asynchronous” for the Mirror type.

When you get to the Attributes screen take the defaults.

Take the defaults on the next few screens, select w3k-241 for the Select Servers screen

Click Finish, Finish

2. Note the difference on the “Primary LUNs” status Mirrored Snapshot Active. MirrorView/A uses snapshots to keep track of changed data on the source LUN. Check out the following containers by expanding each one and note their contents. Also, verify the mirror has been created on the secondary array under remote mirrors

SPs

Reserved LUN Pool ( should have a “Allocated” LUN on the owning SP)

2. Expand the LUN Folders container. A striped metaLUN consists of a single Component with a number of LUNS that comprise the metaLUN. Available LUNS are the same size and RAID Type of the “base or source” LUN. Right click on the metaLUN to view the properties. Expand the Private LUNs container, RAID Group container where that the LUN is contained under, and the Storage Group in which the LUN is in. Note the numbers to the right of the LUNs are assigned by the wizard. These will be different depending on the array model.

Lab 13 : Expanding LUNS - Concatenation Expanding LUNs on a CLARiiON is how you can increase the capacity of an existing LUN You must first create a LUN to use for the base metaLUN. MetaLUNs can be created using two methods, Striping and Concatenation. The lab will have you create a metaLUN using concatenation.

Step Action

1. Click on the Expand icon, Click Next. Select server w3k-240 Storage Array CX3-40-BOTTOM, click Next Select LUN 0, Click next Click the radio button for Concatenation, Click Next From the “Select Unused LUN window” select LUN 20, Click Next From the “Specify metaLUN Capacity window” take the default of maximum capacity, Click Next From the “Specify new LUN settings window” take the defaults.Click Next From the “Summary window” verify the capacity is correct ( 25GB). Click Finish From the “Results window” , Click Finish Verify the settings from the Summary window

2. Expand the LUN Folders container. Expand LUN 0. A concatenated metaLUN consists of multiple components with a number of LUNS that comprise the metaLUN. Available LUNS can be different sizes and RAID Types than the “base or source” LUN. Right click on the metaLUN to view the properties. Expand the Private LUNs container, RAID Group container where that the LUN is contained under, and the Storage Group in which the LUN is in. Note the numbers to the right of the LUNs are assigned by the wizard. These will be different depending on the array model.

Lab 14: LUN Migration The LUN migration feature lets you move the data in one LUN or metaLUN to another LUN or metaLUN. You might do this to change the type of drive the data is stored on (for example, from more economical ATA to faster FC, or vice-versa), to select a RAID type that better matches the data usage, and/or recreate a LUN with more disk space.

Step Action

1. Expand RAID Group 1 on the CX3-40 BOTTOM array Right click on LUN 11 and check the properties. Verify the LUN size. Cancel Right click on LUN 11 again and click Migrate Expand both SP’s to view available LUNs. Note they may be from different RAID Groups. Select LUN 21 click Next , click OK to start the Migration. Right clicking on the properties of LUN 11 will now show a “migration” tab on the upper right side of the window, click on the tab to show the status. After migration completes verify the following; Under which RAID Group does LUN 11 reside? Where is LUN 21? What is the RAID Type for LUN 11? Verify the settings from the Summary window

2. End of Exercise



Summary In this lab, you used Navisphere Manager to configure two CLARiiON Storage Systems. In the process of implementing the configuration you:

• Configured RAID Groups on two CLARiiON Storage Systems to allow for binding LUNs of a particular RAID type

• Bound LUNs on the new RAID Groups to create disk resources for the host computers and implement the RAID protection for data

• Populated Storage Groups with host computer and LUNs to allow the host computers access to disk resources create on the CLARiiON Storage Systems

• Created a Clone within one of the CLARiiON Storage Systems to allow for easy backup of the data without impacting the production LUNs performance

• Created SnapShots for multiple LUNs to facilitate easy backups without the high resource overhead required by Clones

• Created MirrorView Synchronous and Asynchronous Mirror Replicas • Created San Copy Full and Incremental Replicas • Created Striped and Concatenated metaLUNs • Migrated an existing LUN to another LUN



Assessment Questions Please answer the following questions.

1. When creating a RAID Group, what are you doing to the disks involved?

a. Changing the domain name. b. Creating a disk group that can be bound into a specific RAID Type using the Bind

LUN process. c. Selecting the domain RAID settings to allow the Storage System to vary the RAID

information sent to the Management GUI at shortened intervals. d. Configuring SP-A and SP-B exclusive RAID type settings.

2. When is a disk is available to a attached host ?

a. When a LUN is bound b. When a RAID Group is created c. When the disk is bound and in a Storage Group

3. The Host Computer is typically placed into a single Storage Group?

True False

4. Which two CLARiiON replication methods use resources from the RLP?

a. MV/S-MVA b. MV/A-SANCopy Full c. MVA- SANCopy Incremental

5. Which San Copy method copies the entire contents of the source disk to the destination disk?

a. San Copy Incremental b. San Copy Full

6. Which statement is true when creating a Clone?

a. Source and Destination LUNS must be the same size and RAID Type b. Destination LUN can be the same size or larger than the Source c. Source and Destination LUNS must be the same size but different RAID Types
