HP Matrix Operating Environment 7.0 Recovery Management User Guide

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 “Storage setup” (page 10), “Networking setup” (page 9),
and “ Remote Site logical server setup” (page 16) to re-add the logical server to the Matrix recovery
management configuration.
NOTE: 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, refer to: Logical servers −> Menus &
screens −> Manage portability groups in the HP Matrix OE Visualization and Logical Servers online
help.
Remote Site logical server setup
1. Deactivate and gracefully shutdown 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, failover 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.
NOTE: 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.
NOTE: 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.
NOTE: The names of recovery logical server storage pool entries must be the same as
the Local Site logical server storage pool entries.
b. Refresh Virtual Machine resources using the Logical Servers Refresh operation in the Tools
menu of the Visualization tab in Matrix OE visualization.
4. Create recovery logical servers using Matrix OE visualization. Specify the replicated LUNs
information as part of logical server creation. When entering storage information during VM
hosted logical server creation, select the datastore name of the datastore where the VM hosted
logical servers were created.
