Grouping volumes into autonomic groups, Domain sets – HP 3PAR Recovery Manager Software User Manual
Page 23
Before you start configuring Recovery Manager for Availability Group:
•
Make sure all the prerequisites for Availability Group are met before discovering Availability
Group in the Recovery Manager for SQL. For list of prerequisites, see
•
Make sure all the nodes participating in the Availability Group are part of the same Windows
cluster and user has a Domain account and is an administrator for the system.
WARNING!
•
HP 3PAR Recovery Manager for SQL does not support Availability Group databases received
from multiple StoreServs.
•
Do not make any change in the Availability Group configuration while HP 3PAR Recovery
Manager for SQL operations are in progress. Otherwise, the results may be unpredictable.
•
Remote copy is not supported for availability databases.
•
HP 3PAR Recovery Manager for SQL does not support Availability databases when any of
the Availability Group replicas is a part SQL cluster.
NOTE:
If there is any change in the configuration of Availability Group, user must perform a
manual rescan in Recovery Manager for SQL.
Grouping Volumes into Autonomic Groups
You can group virtual volumes into autonomic groups (domain sets, volume sets, or host sets).
Domain Sets
If your SQL Server configuration involves multiple database servers that belong to different HP
3PAR Virtual Domains, you can use the domain set feature to group these virtual domains into one
HP 3PAR StoreServ Storage System domain set. This configuration allows to use just one Recovery
Manager backup server to manage all database servers.
•
All hosts, users, and virtual volumes, including the backup server, must belong to the same
HP 3PAR Virtual Domain.
•
To mount a virtual copy or media backup to a server that is in a different HP 3PAR Virtual
Domain than the domain in which it was created, you must use the Recovery Manager CLI
command HpRmCli Sql mount -ts. For more information about the command, see
•
To create a Remote Copy group for a virtual volume that is in a user-defined domain, the
associated virtual volume on the Remote Copy backup server must be in the same user-defined
domain.
To configure domain sets, use HP 3PAR CLI commands to:
1.
Ensure you are running HP 3PAR Operating System Software 2.3.1 or later.
2.
Ensure you have access to all domains.
3.
Create a domain set that contains all HP 3PAR Virtual Domains for all the database servers.
4.
Create a Common Provisioning Group (CPG) belonging to the new virtual domain.
5.
Create a virtual volume belonging to the CPG created as in step 4.
6.
Create a host belonging to the virtual domain.
7.
Export the VLUN to the host.
8.
On the Recovery Manager backup and production servers, set the user for the HP 3PAR VSS
Provider Software.
