BACKUPCPU number
is the processor in which the backup IOP starts. The process must be in the
STOPPED state or not running for you to alter this attribute.
BACKUPLOCATION ( group,module,slot )
is the location of the adapter that controls the backup path to the device. This
attribute has no default value. If this attribute is not specified, the device is not
accessible through its backup path.
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.
number is the SAC subdevice number on the adapter.
If you specify BACKUPSAC in number format, you must also
specify BACKUPLOCATION.
name is the full name of the SAC location. For example:
SNDA.SAC-1.GRP-21.MOD-1.SLOT-53
