HP Matrix Operating Environment 7.0 Recovery Management User Guide

3 Testing and failover operations
This chapter contains sections on testing Recovery Groups, planned failovers and unplanned
failovers using the Activate... and Deactivate... operations.
Testing Recovery Groups
There are two ways to test Recovery Groups:
• Test individual Recovery Groups using Maintenance Mode
• Perform a planned failover to test all Recovery Groups (see “Planned failover” (page 22) for
more information)
This section focuses on testing individual Recovery Groups using Maintenance Mode.
Maintenance Mode is used to test Recovery Groups to ensure they will function properly when an
Activate... operation is performed. Maintenance mode temporarily stops Matrix recovery
management from managing a DR Protected logical server. One use of maintenance mode is to
perform failover rehearsal. By setting Maintenance Mode on a Recovery Group, all of the logical
servers in that Recovery Group can be activated using Matrix OE visualization. Once you are
satisfied with the failover rehearsal, a Recovery Group and its corresponding logical servers can
be brought back under the control of Matrix recovery management by disabling Maintenance
Mode on that Recovery Group.
At the Remote Site, the logical servers being managed by Matrix recovery management are known
as recovery logical servers. Normally, a recovery logical server cannot be activated except by
invoking an Activate... operation from the Matrix recovery management user interface at the Remote
Site.
To test a Recovery Group using Maintenance Mode, follow these steps:
1. At the Local Site, use the Logical Servers Deactivate operation in the Tools menu of the
Visualization tab in Matrix OE visualization, to gracefully shutdown the logical servers in the
Recovery Group .
NOTE: If the Matrix recovery management configuration includes HyperV logical servers,
bring the cluster disk resource used for logical server storage offline.
2. At the Remote Site, use the appropriate storage management tools, for example, HP P6000
Continuous Access Software, to failover the storage corresponding to the Recovery Group to
the Remote Site.
3. If there are logical servers in the Storage Replication Group that will be activated on VM hosts
during the test:
a. Rescan storage using VM host management tools, for example, VMware Virtual Center,
to ensure that the VM host recognizes the failed over storage.
b. Refresh Virtual Machine resources using the Logical Servers Refresh operation in the Tools
menu of the Visualization tab in Matrix OE visualization.
4. Place the Recovery Group into Maintenance Mode at the Remote Site using the Enable
Maintenance Mode button in the Matrix recovery management Recovery Groups tab.
5. Using the Logical Servers Activate operation in the Tools menu of the Visualization tab in
Matrix OE visualization, activate the logical servers in the Recovery Group at the Remote Site.
Depending on the type of logical server, the activation may be on VC blades, VM hosts or
both. When the test is complete, gracefully shutdown the operating systems, then deactivate
the logical servers.
NOTE: If the Matrix recovery management configuration includes HyperV logical servers,
bring the cluster disk resource used for logical server storage offline.
