During command command processing, a volume cannot be used because there is a storage pool volume defined or a volume in the volume history file with this volume name. Such a volume may still contain valid data. Applying the volume name to the cartridge can overwrite data and or cause library inventory corruption. If the volume is in the volume history file, it has been previously used by for an export, database dump, database backup operation, or by a library client (as recorded in the volume history).
If the SEARCH=YES option was specified, the current volume is skipped and command processing continues with the next volume found. If SEARCH=NO was specified, command processing terminates.
If the volume is present in an automated library, it should either be removed or checked into the library's inventory in the PRIVATE category.
