HP Matrix Operating Environment 7.0 Recovery Management User Guide

6. At the Remote Site, take the Recovery Group out of Maintenance Mode using the Disable
Maintenance Mode button in the Matrix recovery management Recovery Groups tab.
7. At the Local Site, repeat the storage failover, rescan and refresh (if needed) sequences, then
activate the logical servers in the Recovery Group using Matrix OE visualization.
When you import a Matrix recovery management configuration at the Remote Site, all Recovery
Groups that are imported will have Maintenance Mode enabled by default, so they can be tested.
Similarly, a Recovery Group created at the Remote Site will have Maintenance Mode enabled by
default. Once testing is completed for all imported Recovery Groups at the Remote Site, deactivate
the recovery logical servers belonging to each Recovery Group using Matrix OE visualization,
then disable Maintenance Mode on each Recovery Group. Recovery groups that have Maintenance
Mode enabled will not be included in an Activate... operation. HP recommends that you carefully
test Recovery Group failover at the Remote Site, prior to disabling Maintenance Mode on imported
Recovery Groups.
Failover operations
This section explains the difference between planned and unplanned failovers, and provides the
procedure to follow in either case.
Planned failover
A planned failover typically involves an expected outage at one of the sites in a Matrix recovery
management configuration. For example, a planned failover might be necessary to perform
scheduled maintenance, or to react to a severe weather forecast. It can also be used for testing
purposes.
A planned failover includes a series of steps performed first at the site you plan to shut down, and
then at the other site in the Matrix recovery management configuration.
At the site you plan to shut down:
1. Shut down the applications and operating system on each Matrix recovery management DR
Protected logical server in each Recovery Group set.
2. From the Matrix recovery management Sites tab, perform a Deactivate... operation to deactivate
and disable DR Protected logical servers in the Recovery Group Sets that are activated.
NOTE: If the Matrix recovery management configuration includes HyperV logical servers,
bring the cluster disk resource used for logical server storage offline.
NOTE: When a Deactivate... operation is invoked, the status of Recovery Groups that are
being deactivated will not change on the Matrix recovery management Sites or Jobs screens,
until the Deactivate... operation has completed. While the Deactivate... operation is running,
there may be some Recovery Groups that have been deactivated while others are still in the
process of being deactivated.
At the site you plan to fail over to:
1. Ensure that enough resources are available to run the recovery logical servers.
2. From the Matrix recovery management Sites tab, perform an Activate... operation to activate
the DR Protected logical servers in the Recovery Group sets that were deactivated at the other
site in the Matrix recovery management configuration.
NOTE: When an Activate... operation is invoked, the status of Recovery Groups that are
being activated will not change on the Matrix recovery management Sites or Jobs screens,
until the Activate... operation has completed. While the Activate... operation is running, there
may be some Recovery Groups that have been activated while others are still in the process
of being activated.
