PORTNAME number
is the Fibre Channel port name used by the path to a tape volume. The number should be
entered as a 16 character hexadecimal number, without a leading %H.
PRIMARYCPU number
is the processor in which the primary IOP starts. If you omit this attribute, the processor is
automatically chosen based on the physical location of the device.
PROGRAM [[$vol.]subvol.]fileid
is the object file name of the IOP. If not specified, PROGRAM is:
$SYSTEM.SYSTEM.OTPPROCP
If you specify PROGRAM as $SYSTEM.SYSTEM, the operating system first searches for the file
on $SYSTEM.SYSTEM and on the current SYSnn subvolume.
RECSIZE number
is the configured record size for the device (in bytes). This value is used by some utility programs
when making requests to the IOP. number is in the range 1 through 57344. The default is
4096. Larger block sizes should give better performance.
SAC { number | name }
is the SAC that controls the primary path to the device
is the SAC subdevice number on the adapter.number
is the full name of the SAC. For example:SNDA.SAC-1.GRP-1.MOD-1.SLOT-53 .name
STARTSTATE { STARTED | STOPPED }
specifies whether the IOP is available to other processes (STARTED) or unavailable (STOPPED)
when the system is loaded or reloaded. The default is STARTED.
ADD TAPE Examples
See the procedure for “Adding an Open SCSI Device” (page 174).
• To add a tape drive named $TAPE0 in group 02, slot 55:
-> ADD TAPE $TAPE0, SENDTO STORAGE, LOCATION (1,1,55)
• To add a tape drive named $TAPE1 that is connected to SAC 1 in the SNDA in group 01,
slot 53:
-> ADD TAPE $TAPE1, SENDTO STORAGE, LOCATION (1,1,53), &
-> SAC 1, DEVICEID 4
ALLOWOPENS Command
The ALLOWOPENS command permits an object to accept opens again; reverses the effect of the
STOPOPENS command.
ALLOWOPENS is a sensitive command.
ALLOWOPENS DISK Command
The ALLOWOPENS command permits file opens on a specified physical disk volume.
The syntax is:
ALLOWOPENS [ / OUT file-spec / ] DISK $disk
[ , POOL $pool ] [ , SEL state ]
[ , SUB { ALL | MAGNETIC | VIRTUAL } ]
[ , SUPERONLY ]
