HP StorageWorks EVA Virtualization Adapter administrator guide (5697-0177, October 2009)

NOTE:
Snapclones, mirrorclones, and the ability to choose different disk group for clones are not currently
supported with SRM or HP EVA Virtualization Adapter.
Creating vdisks for datastores
Vdisks (vdisks) need to be created for virtual machine datastores. Create the vdisks on the protected
HP EVA disk array, using HP StorageWorks Command View EVA or HP StorageWorks Storage System
Scripting Utility (SSSU) Command Line Interface.
Once vdisks have been created on the local EVA, create data replication groups containing the vdisks.
Data replication groups are created on the local HP EVA disk array and provide vdisk failover between
two HP EVA disk arrays. You can create data replication groups using HP StorageWorks Command
View EVA or SSSU.
For more information on these tasks, see the HP StorageWorks Command View EVA user guide and
the HP StorageWorks Storage Software Scripting Utility Reference.
Presenting LUNs
Once vdisks have been created and put into a data replication group local LUNs should be presented
to local ESX server. When you put a vdisk into a data replication group, it will be replicated to the
remote EVA. At the remote data center, you then need to present the replica vdisk to the ESX servers
that are hosts to the remote EVA.
After you present the vdisks to both local and remote ESX servers, log into the local ESX servers and
do a rescan. There is no need to rescan for LUNs on the remote ESX servers, since SRM does this
during failover. You can present LUNs using HP StorageWorks Command View EVA or SSSU.
For more information on these tasks, see the HP StorageWorks Command View EVA user guide and
the HP StorageWorks Storage Software Scripting Utility Reference.
Creating and configuring datastores
The following tasks need to be done on protected and recovery ESX servers after LUN presentation:
On protected ESX servers
• Create datastores on ESX server
• Install virtual machines onto the datastores
• Create resource pools and folders as needed
On recovery ESX servers
• Rescan to make sure LUNs can be seen from protected site
For more information on these tasks, see the VMware Site Recovery Manager Administration Guide.
