ADD POOL Command (Super Group Only)
APPEND { ON | OFF }
designates whether tape volumes of LABELS type BACKUP can contain multiple
tape files.
This option does not affect tapes of LABELS type ANSI and IBM, which can always
contain multiple tape files. APPEND is not allowed on open-reel tape drives since
this drive type does not have the technology needed to support APPEND. Thus, a
setting of APPEND ON has no effect on pools of TYPE OPEN.
ON
indicates that tape volumes of LABELS BACKUP can contain multiple tape
files.
OFF
indicates that tape volumes of LABELS BACKUP can contain a single tape file.
The default is OFF.
AUTOSCRATCH { ON | OFF }
determines the status of a tape in the pool after all the catalog entries for its files
have expired:
ON
changes a tape’s status to scratch, meaning it is considered empty and ready
for immediate use when a scratch tape is requested from the pool. The default
is ON.
OFF
changes a tape’s status to released, meaning it cannot be reused until its
status is manually changed to scratch in the catalog with ALTER
TAPEVOLUME.
DENSITY { 1600 | 6250 | ANY }
sets the density for open-reel tapes in the pool. The default is ANY, meaning
both densities can be in the pool or the pool consists of cartridge tapes.
Since the DENSITY option is only supported by the open-reel tape drives, this
option has no effect when specified along with the cartridge TYPEs of
CART3480 or CART5120.
LABELS { ANSI | ANY | BACKUP | IBM }
determines the type of tape label allowed in the pool:
ANSI
The label is in American National Standard Institute (ANSI) format. For detailed
information on this label format, see Appendix A, Tape Label Formats.
