During a database backup operation, a volume cannot be used because it is already defined in a storage pool, or has been previously used by an export, a database dump, or a database backup operation (as recorded in the volume history) or is in use by another process.
If the database backup was started with the BACKUP DB command, the database backup is ended and server operation continues. If the database backup was triggered automatically, the backup stops and the server waits for the retry period to expire and then tries the database backup again.
Specify a volume that is not in use or defined in a storage pool, and that has not been previously used for an export, a database dump, or a database backup operation as recorded in the server volume history information. The QUERY VOLUME command may be used to display the names of volumes that are defined to server storage pools. The QUERY VOLHISTORY command may be used to display the names of volumes that have been used for export, database dump, or database backup operations.
