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

BACKUPPORTNAME number
is the Fibre Channel port name used by the backup path to the Open SCSI device. The number
should be entered as a 16 character hexadecimal number, without a leading %H.
BACKUPSAC { number | name }
is the SAC that controls the backup path to the device
is the SAC subdevice number on the adapter. If you specify BACKUPSAC in number format, you must
also specify BACKUPLOCATION.
number
is the full name of the SAC location. For example:SNDA.SAC-1.GRP-1.MOD-1.SLOT-53name
HIGHPIN { ON | OFF }
specifies whether the IOP can run at a high PIN (ON, the default) or only at a low PIN (OFF).
LUN number
is the logical unit number (LUN) of a device connected to the Open SCSI device. For devices
connected to a SCSI controller number is in the range 0 through 7. For Fibre Channel devices
number is in the range 0 through 32767.
MAXOPENS number
is the maximum number of concurrent opens allowed for the device. number is in the range
1 through 64. The default is 3.
NUMIO number
is the number of concurrent I/O operations that the Open SCSI IOP can have outstanding. This
value determines the size of the allocated data-buffer area. number is in the range 1 through
15. The default is 8.
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.
PRIMARYLOCATION ( group,module,slot )
is the location of the adapter that controls the primary path to the Open SCSI device. This
attribute is required.
PRIMARYPORTNAME number
is the fiber channel port name used by the primary path to the Open SCSI device. The number
should be entered as a 16 character hexadecimal number, without a leading %H.
PRIMARYSAC { number | name }
is the SAC that controls the primary path to the device
is the SAC subdevice number on the adapter.number
is full name of the adapter location including the SAC number. For
example:SNDA.SAC-1.GRP-1.MOD-1.SLOT-53
name
PROGRAM [[$vol.]subvol.]fileid
is the object file name of the IOP. If not specified, PROGRAM is:
$SYSTEM.SYSTEM.TDSCSI
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.
