Precautions regarding the drive when mounting data to a backup server
When Application Agent performs tape backup, it mounts the secondary volume to the backup server.
If you specify a mount point in the command arguments when performing tape backup, Application
Agent automatically uses the next available drive (in alphabetical order) after the specified drive
excluding drive A and drive B. You cannot specify a drive other than the first drive for mounting data.
You will need to specify the drive to be used when mounting data to the backup server. Specify this
drive in the configuration definition file for tape backup according to the same sequence as that used
when Application Agent automatically mounts data using a tape backup. For details on the
configuration definition file for tape backup, see “
Creating a configuration definition file for tape
backup ” on page 156.
Make sure to specify the same drive for use at backup and at restoration. If the drive used by
Application Agent at backup is used at restoration, restoration from the tape may fail.
Precautions when importing backup information
If you use the drmdbimport command to import backup information, including the copy group of
a mounted volume, while the secondary volume is mounted using the drmmount command, the import
will fail. In this case, use the drmumount command to unmount the secondary volume, and then
execute the drmdbimport command again.
Command execution conditions
If you execute the drmmount command, drmmediabackup command, or drmmediarestore
command for a copy group in the PAIR status, a detailed message will be output indicating that the
pair status of the copy group is invalid, and then the command terminates with an error.
In this case, execute the command after using the RAID Manager pairsplit command to set the
pair status of the copy group to SSUS .
Precautions when updating dictionary map files
You need to update the dictionary map files at the following times (regardless of whether the operation
target is subject to backup):
• When the RAID Manager configuration definition files have been modified.
• When the volume pair configuration has changed.
• When a mount point (a drive letter) has changed.
• When the disk configuration has changed because of addition or removal of a hard disk.
• When the drmdbsetup utility was executed to change the storage location of the dictionary map
files.
Create or delete an SQL Server instance # .
• When an SQL Server instance has been created or deleted.
• When an SQL Server database has been added or deleted.
• When the name of an SQL Server database has been changed.
• When an SQL Server database configuration file has been added or deleted.
• When the name of SQL Server database configuration file has been changed.
• When an SQL Server database configuration file has been moved.
• When a dynamic volume has been expanded.
