DG02.

Precautions for volume configuration
• You cannot use Application Agent in a configuration where a physical volume is divided into
multiple disk groups using logical volume manager.
• Do not use any functions that let you freely expand or reduce the capacity of a logical volume. If
you use such functions, Application Agent will not perform backup and restoration correctly. This
is because the number of physical volumes that make up the logical volume changes according
to the change in capacity of the logical volume. Application Agent checks whether the configuration
of logical volumes has been changed and, if changed, restoration terminates with an error.
• If the volumes to be processed by Application Agent contain an LDEV for which a mode other
than the normal mode is specified for the access level by using Data Retention Utility, neither a
backup nor a restoration can be performed.
• When executing backup and restoration of file systems and databases, Application Agent mounts
and unmounts the volume subject to processing. In this situation, set the mount point directory
name as follows:
• One mount point can be specified for each logical volume.
• Allocate database files and file systems that are not subject to backup and restoration so that they
are not included in the same disk configuration unit as those that are subject to backup and restor-
ation.
• Allocate database files and file systems that are backed up simultaneously but may be restored
separately so that they are not included in the same disk configuration unit as those that are subject
to backup and restoration.
• If one disk group contains multiple physical volumes, Application Agent performs volume duplication
operation for backup only by the number of physical volumes.
• Precautions relating to mounting a directory
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.
