ADD DISK Command
AUTOSTART { ON | OFF }
specifies whether to automatically start the disk process when an internal or M8xxx
the disk is inserted.
DISK AUTOSTART ON is ignored if SUBSYS AUTOSTART is OFF.
For information about using this attribute, see Mirrored Disk Placement on
page 6-12.
BACKUPCPU number
is the processor in which the backup IOP starts. If you omit this attribute, the
processor is automatically chosen based on the physical location of the device.
The processor in which the primary IOP runs and the processor in which the
backup process runs need not be located in the same topology branch.
BACKUPDEVICEID { number | ( shelf, bay ) }
(45xx and M8xxx disks only) is the device ID of the disk accessed on the backup
path to the disk. This attribute is optional. If specified, it must be the same device
ID as that specified for PRIMARYDEVICEID (page 14-19).
For 45xx disks:
For M8xxx Fibre Channel disks:
If you configure a disk volume for use with an FCSA connected to an ESS, you
cannot specify BACKUPDEVICEID.
BACKUPLOCATION ( group, module, slot )
(45xx and M8xxx Fibre Channel disks only) is the location of the adapter that
controls the backup path to the device. This attribute is optional if BACKUPSAC
(page 14-12) is given in name format but required if BACKUPSAC is given in
number format.
The primary path and the backup path need not be located in the same topology
branch, nor do they need to be in the same topology branch as the processors.
ON enables automatic starting.
OFF disables automatic starting.
number
is the unit number of the disk in the modular disk
subsystem. number is in the range 1 through 7.
shelf is the disk-drive enclosure’s shelf number. shelf is in the
range 1 through 4.
bay is the number of the disk. bay is in the range 1 through 14.
