Lab Exercise 4:

Configuring SnapView Snapshots

Purpose:

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 both the session and
snapshot would survive the storage system power failure, as long
as all sessions run in persistent mode.

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.

Objectives:

In this exercise, students will:

• Create Snapshots using the Wizard
• Remove

Snapshots

Lab Exercise 5:

Configuring SnapView Clones

Purpose:

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.

Objectives:

In this exercise, students will:

• Create Clones with the Wizard
• Use Clone commands
• Remove

Clones

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.

Objectives:

In this exercise, students will:

• Create a Synchronous Mirror
• Remove a Synchronous Mirror
• Create an Asynchronous Mirror
• Remove an Asynchronous Mirror

Step

Action

Expand and examine the following containers on the Primary ( cx4-Top-90) and
Secondary (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 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.

On the Primary array (cx4-Top-90) open the “Remote Mirrors” container and
expand out all options.

Right click on the “Secondary Image” and note the options.

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

Did the Primary and Secondary Mirrors switch states?

Try promoting the Primary image. What happened?

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 click “Remove”.

Right click on the Mirror Name and click “Destroy”.

Read the Welcome window and click Next.

From the “Select Servers” window highlight w3k-240 and click Next.

From the “Select Primary Storage System” window select cx4-Top-90 and click
Next.

From the “Select Storage LUN” window expand the Storage Group w3k-240, check
the box for MVS_Source_LUN1, highlight the LUN in the “Selected LUNs” menu.
Click Next.

From the “Select Secondary Storage System” window select cx4-Bott-92 and click
Next.

From the “Select Mirror Type” window read the dialog for the Mirror types and
choose “Asynchronous”. Click Next.

From the “Attribute” window read the dialog, keep the defaults, and click Next

From the “Configuration” window click Next.

From the “RAID Configuration” window keep the defaults and click Next.

From the “Select Servers” window, leave the defaults, and select w3k-241. Click
Next.

Read the Summary window and click Finish.

Read the “Results” window click Finish.

Note the difference on the ““MVA_Source_LUN2” status. 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.

Lab Exercise 8: Expanding LUNs and Migrating LUNs

Navisphere Manager Simulator Lab v3.28

Page 45 of 50

Purpose:

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

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.

Objectives:

In this exercise, students will:

• Expand a LUN using Stripe Expansion
• Expand a LUN using Concatenation expansion
• Migrate
