HP Matrix Operating Environment 7.3 Recovery Management User Guide

If your implementation of the storage adapter commands requires passwords to manage storage
replication, the storage adapter command implementation must handle passwords securely. It is
your responsibility to encrypt/decrypt passwords while saving and retrieving them.
Setting up Local Site logical servers
The following conditions must be met before you can configure a logical server for DR protection.
1. You must ensure that the logical server is associated with SAN based storage.
2. A logical server must have been activated at least once.
3. An operating system and applications must be installed on a logical server.
Logical servers that meet these conditions appear in the Available LS(s) list in the Local Site Matrix
recovery management configuration GUI, even if they are deactivated after they have been activated
for the first time.
For sites with a large number of logical servers, partitioning logical servers into portability groups
can reduce activation time during failover. HP recommends that the portability group associated
with logical servers on both the Local Site and the Remote Site be limited to a subset of virtual
machine hosts and virtual connect blades that are capable of hosting these logical servers. For
additional information on configuring portability groups, see Logical servers→Menus &
screens→Manage portability groups in the HP Matrix OE Visualization and Logical Servers online
help.
NOTE: You cannot change the datastore of a VM-hosted logical server while it is being managed
by Matrix recovery management. To change the datastore, first remove the VM-hosted logical
server from the Matrix recovery management configuration, then use the Logical Servers Activate
operation in the Tools menu of the Visualization tab to change the datastore. After the datastore
has been changed, follow the steps in “Setting up Storage” (page 10), “Setting up Networking”
(page 9), and “ Setting up Remote Site logical servers” (page 16) to re-add the logical server to
the Matrix recovery management configuration.
Setting up Remote Site logical servers
1. Deactivate and gracefully shut down the logical servers in the Recovery Groups at the Local
Site using Matrix OE visualization.
2. Using the appropriate storage management tools (for example, HP P6000 Continuous Access
Software), fail over the storage associated with the Recovery Groups to the Remote Site.
3. If there are VM-hosted logical servers that will be DR Protected:
a. Rescan storage using VM host management tools, for example, VMware Virtual Center
or Microsoft Hyper-V Management Console, to ensure that the VM host recognizes the
failed over storage.
• The replicated disk on the Remote Site Hyper-V host must be configured with the
same drive letter that is assigned to the Local Site disk it is replicated from.
In the case of a cluster shared volume, the replicated disk on the Remote Site Hyper-V
host must be configured with the same volume path that is assigned to the Local Site
disk it is replicated from.
In the case of a cluster shared volume or shared cluster disks, the replicated disk on
the Remote Site Hyper-V host must be configured with the same cluster resource name
that is assigned to the Local Site disk it is replicated from.
• When creating recovery logical servers, you must specify the datastore name for the
logical server. The datastore name selected must be the same as the datastore name
for the Local Site logical server.
