SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

HIGHPIN { ON | OFF }
specifies whether the IOP can run at a high PIN (ON, the default) or only at a low PIN (OFF).
KEYGENPOLICY { KEYPERDRIVE | KEYPERTAPE | NOENCRYPTION
specifies the key generation policy for the tape drive while it is stopped. You cannot use this
attribute in the same command line as the NEWENCRYPTKEY attribute.
NOTE: Only members of the SAFEGUARD security officer group on the local system can
perform an ALTER TAPE command with the KEYGENPOLICY attribute.
LOCATION ( group, module, slot )
is the location of the adapter where the tape drive is connected.
LUN number
is the logical unit number (LUN) used by the path of the tape volume in the range 0 through
31.
MAXOPENS number
is the maximum number of concurrent opens allowed for the device. number is in the range
1 through 64. The default is 4.
NEWENCRYPTKEY
sets a new encryption key on a tape drive while it is stopped. The drive's KEYGENPOLICY
must be set to KeyPerDrive.
NOTE: This attribute is not valid for the ADD TAPE command and the PROFILE object.
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. The process must be in the STOPPED state or
not running for you to alter this attribute.
PROGRAM [[$vol.]subvol.]fileid
is the object file name of the IOP. If not specified, PROGRAM is:
$SYSTEM.SYSTEM.OTPPROCP
If you specify the program file name location as $SYSTEM.SYSTEM, the operating system first
searches for the file there 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-53name
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.
