HP StorageWorks P9000 Replication Manager Software 7.1 CLI User Guide (TB584-96026, May 2011)

Setting up RAID Manager
To back up data by using Application Agent, you need to create a RAID Manager configuration
definition file (horcmn.conf, when n is the instance number) for each instance, to match the intended
usage.
The location of the RAID Manager configuration definition file (horcmn.conf) is as follows:
In Windows Server 2003 or Windows Server 2008:
system-drive\Windows
Note
Do not specify a path to the configuration definition file in the HORCM_CONF environment variable.
In Application Agent, a pair of a primary volume and secondary volume is managed as a copy group.
A copy group is defined by a combination of dev_group and dev_name specified in a RAID
Manager configuration definition file.
Application Agent does not allow duplication of copy group names on the same server. If more than
one RAID Manager instance is activated, make sure that the combination of dev_group and
dev_name is unique among all the RAID Manager configuration definition files.
If the system contains both a copy group that is subject to Application Agent backup operation and
a copy group that is not subject to Application Agent backup operation, the conditions below must
be met. If an Application Agent command is executed when the conditions below are not met, pair
volumes that are not subject to backup operation will enter an unexpected state.
• A copy group that is subject to Application Agent backup operation and a copy group that is not
subject to Application Agent backup operation must be defined with different dev_group names.
• The primary volumes of all copy groups defined with the same dev_group name as a copy group
that is subject to Application Agent backup operation must be connected to a database server or
file server.
In addition, HP recommends that you define pair volumes that are not subject to Application Agent
backup operation in the RAID Manager configuration definition file (horcm.conf) of a RAID Manager
instance that is different from the one used by Application Agent.
Application Agent supports the HORCM_LDEV section of the RAID Manager configuration definition
file (horcmn.conf) if the RAID Manager version is 01-18-03/06 or later. Application Agent supports
the HORCM_ALLOW_INST and HORCM_LDEVG sections in configuration definition files (horcmn.conf)
if the RAID Manager version is 01-24-03/12 or later.
To check whether the RAID Manager configuration definition file you created is correct, test whether
a RAID Manager instance can be activated. For details on how to activate RAID Manager, see the
RAID Manager documentation. After you make sure that the RAID Manager instances can be activated
correctly, install Application Agent.
This subsection describes how to create RAID Manager configuration definition files for the following
operations:
• Back up one primary volume to multiple generations
• Back up multiple primary volumes to a single generation
• Back up multiple primary volumes to multiple generations
• Back up or restore between storage systems
• Set up a multi-target or cascade configuration
