•
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, HP recommends that you configure
directory mount points that are backup targets so that they are on the same directory level. Making
the directory mount point on the same directory level allows you to manage mount points easily.
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 XP7 Replication Manager Application
Agent CLI Reference Guide.
