Chapter 4. DR Test, Verify, Report, Cleanup, and Recover

Cycle

This section summarizes the process through which VSR cycles through disaster

recovery testing, verification, reporting, cleanup, and recovery.

1. Perform the Disaster Recovery Test.

2. Verify that the Disaster Recovery Test completed successfully.

v Feedback is relatively immediate when you perform a Disaster Recovery Test

for the particular case at hand.

v Feedback is delayed and either retrieved and/or sent by email to designated

recipients when you perform tests by schedule.

3. Report the Disaster Recovery Test results to the IBM VSR Administrator for

verification and system cleanup as required.

Important: Reporting of Disaster Recovery Test results to the IBM VSR

Administrator is important because it initiates verification and system cleanup

by the IBM VSR Administrator before a successive test may be successfully run,

which completion is required before you might reliably perform Disaster

Recovery.

4. VSR performs the requisite system cleanup.

v When you report a Disaster Recovery Test as passed or failed, VSR

automatically performs any necessary cleanup.

v When a Disaster Recovery Test is reported as unfinished, no action is taken.

Note: Cleanup, undertaken by the IBM VSR Administrator following

Disaster Recovery Test reporting, is a process transparent to the user and

Customer VSR Administrator. It involves the following steps:

– Saving the test result

– Deleting the Disaster Recovery Virtual Machine from the ESX machine

(when it persists)

– Deleting the Disaster Recovery Test volume from the SAN

5. Receive acknowledgement from the IBM VSR Administrator that the Disaster

Recovery Test Report was received and success verified.

6. Optionally: Run reports. See Chapter 6, “Accessing System Statistics,” on page

29 for information about producing reports by available types.

7. As required: Perform Disaster Recovery. Perform this step only after testing,

verification, and any required cleanup is completed. For more information, see:

v Chapter 7, “Performing a Disaster Recovery,” on page 33

v “Recovering a Reserved Resource Server” on page 39

v “Recovering a Server Group” on page 38

8. As required: Perform a “Failback” on page 6.
