HP StorageWorks Storage Mirroring Evaluation Guide (T2558-96326, April 2009)

Evaluating Storage
Mirroring
Storage Mirroring configuration consists of creating a replication set, which defines the data on the
source machine that is to be protected, and then connecting that replication set to a target machine.
These two steps, creation and connection of the replication set, are the backbone of the Storage
Mirroring processes. From there you can also use Storage Mirroring failover, failback, and restoration
processes for a high availability solution.
The evaluation consists of the following tasks.
1. Checking your configuration on page 4-2
2. Establishing a connection on page 4-2
3. Monitoring the activity and completion of the initial mirror on page 4-4
4. Changing data to cause replication on page 4-5
5. Verifying the data changes on the target on page 4-6
6. Testing your target data on page 4-8
7. Configuring failover on page 4-9
8. Simulating a failure on page 4-11
9. Simulating data changes after failover on page 4-11
10. Performing failback on page 4-12
11. Restoring your data on page 4-13
