Configuring SnapView snapshots for SRM testing purposes via NaviSecCli

1. Add the LUNs bound for SnapView Sessions into the Reserved LUN Pool.

naviseccli –h SP ipaddress reserved –lunpool –addlun <LUN IDS separated by spaces>

2. Create a snapshot for each LUN at the recovery site, and add the SnapShot to ESX Server’s

CLARiiON Storage Group at the recovery site.

(

NOTE: This snapshot will not be activated until a user tests the SRM failover operation, in which SRM

will create a session and activate it with the corresponding snapshot.)

naviseccli –h SP ipaddress snapview –createsnapshot <LUN ID>

-snapshotname VMWARE_SRM_SNAP

_LUNID

naviseccli –h SP ipaddress storagegroup –addsnapshot –gname <ESX CLARiiON Storage

Group name> -snapshotname <name of snapshot>

For more information about using Navisphere CLI with MirrorView, please see the

MirrorView/Synchronous Command Line Interface (CLI) Reference, MirrorView/Asynchronous Command

Line Interface (CLI) Reference and SnapView Command Line Interface (CLI) References available on

Powerlink.

EMC recommends that you configure SRM and the CLARiiON MirrorView Adapter with vCenter

Infrastructure after the mirrors and consistency groups have been configured. Refer to the VMware SRM

Administration Guide along with the EMC MirrorView Adapter for VMware Site Recovery Manager

Version 1.3 Release Notes for installation and configuration instructions.

SRM Protection Groups

A Protection Group specifies the items you want to transition to the recovery site in the event of a disaster.

A Protection Group may specify things such as virtual machines (VMs), resource pools, datastores, and

networks. Protection Groups are created at the primary site. Depending on what the SRM will be

protecting, you can define the Protection Group using VMs or based on the application being protected (for

example, distributed application across multi-VMs). Usually there is a 1-to-1 mapping between a SRM

Protection Group and a CLARiiON consistency group. However, if your CLARiiON model does not

support the number of devices being protected within a Protection Group, you can create multiple

CLARiiON consistency groups for each Protection Group.

Table 5 shows the maximum number of devices allowed per consistency group.

The text VMWARE_SRM_SNAP must be somewhere in this name for the SRA adapter to function
