Chapter 5. Usage; Creating The Target Volumes And Metro/Global Mirror Relationships; Adding Array Manager To Vmware Site Recovery Manager - IBM DS8000 User Manual

Chapter 5. Usage

Use the IBM DS8000 SRA to run dependable Disaster Recovery Planning and
protect VMware sites with their DS8000-based datastores.

Creating the target volumes and Metro/Global Mirror relationships

You must create an equal number of target volumes (for Metro Mirror targets) to
source volumes. You must also create an extra set of volumes for FlashCopy targets
for Global Mirror setup on the recovery site DS8000, to source volumes.
Procedure
Create Metro/Global Mirror relationships between the source and target volumes.
Do not map the Metro/Global Mirror target volumes to the VMware ESX servers
on the recovery (secondary) site in a non-preconfigured environment. The reason is
because the mapping process is automated by the SRA for failover and test failover
operations. For more information about Metro Mirror/Global Mirror Copy
Services, see IBM DS8000: Copy Services in Open Environments (PDF).
Important:
1. When you create Global Mirror relationships with SE volumes, use ESE as your
2. Before you use the DS8000 SRA, ensure that the following configuration
If SE volume is not enabled for SRA configuration, the SRA creates fully-allocated
volumes during test failover operations. Fully-allocated volumes must be
initialized before they can be used as FlashCopy targets. This action might take
several minutes, depending on the size of the newly created volume. To
accommodate the timing, the user must modify the DS8000 Command Timeout
(sec) of IBMDS8000Util.exe or leave the parameter empty to make SRA wait until
the newly created volume is ready.
You might also want to change the "storage.commandTimeout" value of VMware
SRM.
