Lab Exercise 4: Configuring SnapView Snapshots

Purpose: A snapshot is a virtual LUN that when activated, allows asecondary server to view a point-in-time copy of a source LUN.

An active snapshot is a composite of a source LUN and reservedLUN data that lasts until you destroy the snapshot. Each snapshotis linked to a source LUN(s). If the storage system loses powerwhile the SnapView session is running both the session andsnapshot would survive the storage system power failure, as longas all sessions run in persistent mode.

Writes to an active snapshot from a secondary server are storedin the reserved LUN pool until the snapshot is deactivated. When

a secondary server deactivates the snapshot, the softwaredestroys all writes made to the snapshot.

Lab Exercise 5: Configuring SnapView Clones

Purpose: A clone is a complete copy of a source LUN. You specify a sourceLUN when you create a clone group. The copy of the source LUNbegins when you add a clone LUN to the clone group. Thesoftware assigns each clone a clone ID. This ID remains with theclone until you remove the clone from its group.

While the clone is part of the clone group and unfractured, any

productionwrite requests made to the source LUN are simultaneouslycopied 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.

Lab Exercise 7: Creating Synchronous and AsynchronousMirrors

Purpose:A remote mirror consists of a primary image and up to twosecondary images. The production image (the one mirrored) iscalled the primary image; the copy image is called the secondaryimage.

MirrorView/S supports up to two remote images. Each imageresides on a separate storage system. The primary imagereceives I/O from a server called the production server; aseparate storage system maintains the secondary image. Thisstorage 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 youmanage with the User Interface (UI). The client that is managingthe storage system containing the primary images can fail over tothe secondary image if the primary image becomes inaccessible.In the previous labs, you created RAID Groups, Storage Groupsattached hosts, and created Clones and Snaps. CLARiiONsarrays 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

5 Expand and examine the following containers on the Primary ( cx4-Top-90) andSecondary (cx4-Bott-92) arrays

LUN Folders > Private LUNs

LUN Folders > SP A and SP B

Storage Groups

Remote Mirrors

Note The write intent log keeps track of writes that have not yet been made to the remoteimage for the mirror. It allows for fast recovery when the primary storage systemfails. When the primary fails and is recovered, the write intent log is used tosynchronize the data on the remote image. Otherwise, a full resynchronizationwould be required for the remote image. In situations where you must replace theprimary storage system due to a catastrophic failure, you can use a promotion toaccess 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, sothat a server can access it.

6 On the Primary array (cx4-Top-90) open the Remote Mirrors container andexpand out all options.

Right click on the Secondary Image and note the options.

Click Promote, read the Warning message, click Yes, then OK.

Lab Exercise 8: Expanding LUNs and Migrating LUNs


45/50



Purpose:Expanding LUNs on a CLARiiON is how you can increase thecapacity of an existing LUN

You must first create a LUN to use for the base metaLUN.MetaLUNs can be created using two methods

The LUN migration feature lets you move the data in one LUN ormetaLUN to another LUN or metaLUN. You might do this tochange the type of drive the data is stored on (for example, frommore economical ATA to faster FC, or vice-versa), to select aRAID type that better matches the data usage, and/or recreate aLUN with more disk space.

Step Action

2 Expand the LUN Folders container.

A striped metaLUN consists of a single Component with a number of LUNS thatcomprise the metaLUN. Available LUNS are the same size and RAID Type of thebase or source LUN. Right click on the metaLUN to view the properties.Expand the Private LUNs container, RAID Group container where that the LUN iscontained under, and the Storage Group in which the LUN is in. Note the numbersto the right of the LUNs are assigned by the wizard. These will be differentdepending on the array model.
