HP StorageWorks Storage Mirroring for Virtual Infrastructure user's guide (T2558-96086, February 2008)

Perform a failover test to verify the quality of the backup data without disrupting clients

1. Click the Failover button.

2. Choose the

Test failover option.

3. Review the target virtual machine to verify that the data quality is acceptable. At this point, you can either:

• Undo the failover as described in step 4.

• Promote the replica virtual machine to be the production server by shutting down the source and

enabling the target replica’s NIC through the Virtual Infrastructure client.

4. Click the

Undo failover button. When you are prompted to confirm, click OK.

At this point, the job will be back in its original configuration.

Pre-Staging Data on the Target

Storage Mirroring for Virtual Infrastructure keeps track of all the information about the association of any

source

.vmdk file to the corresponding target .vmdk file. The mapping information can be used to perform

target pre-staging. Pre-staging means before creating a job, you would copy information through other

means, and after a job is created, Storage Mirroring for Virtual Infrastructure will use a difference mirror

instead of a full mirror.

To pre-stage data, complete the following tasks:

1. Create a job with a delayed protection start time (be sure to allow enough time to complete pre-staging the

data).

2. Get the

.vmdk replica virtual machine disk mapping description from the Target area on the Protection

Summary page.

3. Copy each source

.vmdk file to the correct location on target through other means.

4. Modify the scheduled protection start time to start the job immediately. The difference mirror will begin.
