Extended commands specifications (Tape-related commands)
EX_DRM_CACHE_PURGE (Clears the cache of the secondary volume)
Formats
To clear the cache of the secondary volume when usual operation is in the pair status:
EX_DRM_CACHE_PURGE operation-ID
To clear the cache of the secondary volume when usual operation is in the split state:
EX_DRM_CACHE_PURGE operation-ID
{ -cg copy-group | -cg_file copy-group-list-file }
Description
This extended command sequentially executes the drmmount and drmumount commands to clear
the cache of the secondary volume.
When usual operation is in the pair status, the cache of the secondary volume for the specified copy
group is cleared based on the backup ID created when data is backed up from the primary volume
to the secondary volume. When usual operation is in the split state, you need to specify the copy
group to clear the cache of the secondary volume since the cache needs to be cleared before the
backup.
Prerequisites
The prerequisites for executing this extended command are as follows:
• An operation definition file linked to the specified operation ID has been provided.
• During ordinary paired operation, the file system or the database must have been backed up to
a secondary volume by the following extended command, and a backup ID record file must have
been generated by:
• When backing up a file system, use the EX_DRM_FS_BACKUP command.
• When backing up an SQL Server database, use the EX_DRM_SQL_BACKUP command.
• When backing up an Exchange database, use the EX_DRM_EXG_BACKUP command.
