HP Matrix Operating Environment 7.3 Recovery Management User Guide

vDisks when the failed site recovers. If a failure occurs in the middle of this full copy operation,
the data on the new destination vDisks could be corrupted. To protect the new destination
vDisks, you must enable the HP P6000 Command View auto-suspend setting to prevent an
automatic full copy operation from occurring. To protect the new destination vDisks, you must
back up the data on them before you manually run a full copy operation.
To prevent a full copy of the new source vDisks to the new destination vDisks after the failover
of asynchronous Storage Replication Groups, Matrix recovery management automatically sets
the mode of all asynchronous Replication Groups to synchronous prior to storage failover and
then resets the mode to asynchronous after the storage failover is completed. The storage link
must be up and both the Local Site and Remote Site arrays must be managed by the same
Command View server for Matrix recovery management to perform this operation.
For the failover of asynchronous Storage Replication Groups to succeed, both the Local Site
and Remote Site arrays must be managed by the same Command View server.
Under rare failure conditions, the mode of a Storage Replication Group can be left in
synchronous mode requiring a manual intervention to reset the mode to asynchronous.

• If the password for a Storage Management Server is changed, take the following actions to
refresh the Storage Management Server password on the CMS and in the Matrix recovery
management configuration:
1. Discover the Storage Management Server with the changed password.
2. Go to the Matrix recovery management user interface Storage Management Servers tab.
3. Select the Storage Management Server that has the changed password, and click on
Edit.
4. Select the Refresh SIM Password box and click Save.
HP P9000 storage setup notes
• When HP P9000 Continuous Access Software storage replication is used, Matrix recovery
management depends on the HP P9000 Cluster Extension Software command-line interface
(CLI) to manage storage replication. The HP P9000 Cluster Extension Software CLI must be
installed on a standalone Windows system. HP P9000 Cluster Extension Software depends
on HP P9000 RAID Manager Software to manage P9000 storage replication. HP P9000
RAID Manager Software instances and configuration files must be configured to manage
various device groups that are configured in Matrix recovery management. For more
information, see the following:

h20000.www2.hp.com. Click Manuals, then go to Storage→Storage Software→Storage
