Lab Description

Purpose:

This lab is designed to familiarize the user with 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 Rel 24 of CLARiiON base code.

Note the Simulator does not contain the entire features/function set like the real Navisphere Manager product.

1. This simulator supports only version Jre 1.5_01. Jre above 1.5 will be supported in next release. User's have to uninstall Jre 1.6 if found on the system. 2. If no Jre is present, the Simulator installs one automatically when a user opens the application for first time.

3. Reporting wizard creates the html reports under c:\ ( root). 4. Reset option has been provided in the Simulator once installed. It appears in the menu item like this:

5. Uninstall option is also included in Simulator as shown above. 6. The read me text file is in the install folder for support of Jre 1.5_01. 7. Help file has been updated to reflect all wizard modules.

Lab 4: Configuring SnapView Snapshots

Step Action

1. A snapshot is a virtual LUN and when activated, it allows a secondary server to view a point-in-time copy (SnapView session) 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 a Snapshot on a CLARiiON array.

2. Right click on Replication Tab from the Task Bar

Click on the Configure SnapView Snapshots Icon to launch the Wizard.

Read the dialog

Click Next

Select w3k-240.sa4e.com as the Production Server

Lab 5: 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.

Step Action

1. The next steps will take you through the creation of Clones using the Wizard

2. Right click on LUN 1 > click on the Properties > type in Exchange_DB_LUN 1 for the LUN Name

Lab 8: 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.

2. Expand and examine the following containers on the Primary ( cx3-40-top) and Secondary (cx3-40-BOTTOM) arrays

Private LUNs

SPs

Storage Group

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.

3. 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.

4. 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.

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
