Table 5-5. Disk Drive Status
Status Meaning
UNKNOWN A volume in the UNKNOWN state does not have a label that the system can
recognize. The volume may be from another system, it may be a new disk
pack, or it may be a volume that has been formatted. An UNKNOWN volume is
available for initialization.
SCRATCH A volume in the SCRATCH state can be initialized. It may contain data, but by
scratching the volume, the user has indicated that the data is no longer
needed.
LONER The volume is in the LONER state when its master is not mounted or when
the volume set is closed by the VSCLOSE command.
MASTER A volume in this state is the master volume of a volume set. In order for the
system to recognize the volume set, the master volume must be mounted.
MEMBER A volume in this state belongs to a volume set whose master is mounted. If
the master is not mounted, the volume is in the LONER state.
