HP BACKCOPY Reference Manual page 290

For IBM or IBMBACKUP labeled tapes, the owner ID can be from 1 through 10 characters
long.
PHYSICAL { number }
identifies a backup volume set created by BACKCOPY that contains a file to which you want
to read or write data. BACKCOPY is a standard Backup Restore utility.
number is the physical copy number of the volume set you want and is specified in the range
1 through 99. The default is 1.
If you try to open the same volume set for both USE IN and USE OUT on the same system,
$ZSVR manages the physical copy number of the USE OUT DEFINE for you. If the USE OUT
DEFINE designates a different system than the USE IN DEFINE, you must specify a PHYSICAL
number greater than the USE IN tape file, or an error occurs.
The new duplicated copy has a higher physical copy number than the original, unless
BACKCOPY uses a different FILEID or GEN for the USE OUT DEFINE. Two identical volume
sets created by a parallel BACKUP or a parallel BACKCOPY have the same physical copy
number but different logical copy numbers (1 and 2). If CATALOG is OFF, PHYSICAL is ignored.
PHYSICAL is ignored by Backup and Restore 2.0.
RECFORM { F | U }
specifies the record format.
F—indicates fixed-length records. If you specify RECFORM F, you must specify a BLOCKLEN
value that is a multiple of the RECLEN value.
U—indicates undefined length (the default for IBM tapes).
Additional guidelines:
BLOCKLEN, RECFORM, and RECLEN values are not checked for consistency in the input
files.
For an ANSI-standard labeled tape, these defaults are assumed: RECFORM is U; RECLEN
is 0; and BLOCKLEN is as configured for the device. If you specify BLOCKLEN, RECFORM,
and RECLEN for a labeled tape output file, label fields are generated with those values.
RECFORM is valid but ignored by Backup and Restore 2.0. The record format used
internally will always be FIXED.
RECLEN record-length
specifies the record length of the tape file. For ANSI-standard tapes with fixed-length records
(RECFORM is F), the default RECLEN value is as configured for the device by SYSGEN. For
tapes with undefined record lengths (RECFORM is U), the default RECLEN value is 0 (zero).
RECLEN is valid but ignored by Backup and Restore 2.0. The record length used internally will
always be the user-specified or default value of the BLOCKSIZE job option.
REELS volumes
specifies the number of volumes (reels or cartridges) in a multivolume file. Specify an integer
in the range of 1 through 255.
RETENTION days
specifies the retention period for this tape. For days specify an integer. This value is translated
to an expiration date when the labels are written on the tape. An expiration date prevents
overwriting tape contents. The default is 1 (one); that is, the tape expires the day after being
written. If you specify RETENTION, you cannot specify the EXPIRATION attribute. If the DEFINE
does not include RETENTION or EXPIRATION, the tape expires immediately.
SYSTEM { local-node | remote-node }
identifies the node to which the tape drive is attached. This is where the tapes must be mounted.
If you specify a remote node, it must be a node on your system network. If the DEFINE does
not include DEVICE or SYSTEM, all tapes must be mounted on a local node. You cannot specify
both the SYSTEM and DEVICE attributes.
