When usual operation is in the split state, use an absolute path to specify the copy-group list file that
records the copy group for which you want to clear the cache of the secondary volume. Use this
option if you want to clear the caches for many copy groups at the same time. When the copy group
to be used for the next backup can be identified, specify that copy group. When the copy group to
be used for the next backup cannot be identified, specify all copy groups.
Note
Before you attempt to back up the file system or the database to a secondary volume, execute this
extended command for all secondary volumes of resources to be backed up. If you back up data
without clearing the cache of the secondary volume, when you mount the secondary volume, the
existing cache is overwritten to the secondary volume, and the backup data might be lost.
Return Values
