• If one disk group contains multiple physical volumes, Application Agent performs volume duplication
operation for backup only by the number of physical volumes.
• Do not define the following as copy groups, and do not specify them as backup targets: directories
at a directory mount point, or volumes mounted to a drive. Also, configure directory mount points
that are backup targets so that they are on the same directory level.
The following shows a configuration example of a mounted directory that can become a backup
target. In the figure below, data files and log files are mounted to a directory and specified as
backup targets.
Figure 45 Configuration example of a mounted directory that becomes a backup target
The following shows a configuration example of a mounted directory that does not become a
backup target. When the configuration places a mount point directory on a directory below a
volume, higher-level volumes that contain a volume that was mounted to a directory cannot be
specified as a backup target.

Precautions when changing a volume configuration
• If the following operations or changes are performed on a logical volume manager that is a backup
operation target, or on a file system or RAID Manager configuration definition file (
horcm n .conf ),
then update the dictionary map files before executing backup. Note that if you execute backup
without updating the dictionary map files, a system inconsistency might occur. To update the dic-
tionary map files, use the
drmfsdisplay
,
drmsqldisplay
, or
drmexgdisplay
command.
For details about how to use these commands, see the HP P9000 Replication Manager Software
Application Agent CLI Reference Guide.
