(for internal disks) is the location of the slot where the primary disk of the mirrored

volume is installed.

controls the primary path to the disk.

This attribute is optional if PRIMARYSAC is given in name format but required if

given in number format.

PRIMARYLUN number

LUNs per FCSA and as many as 125 LUNs per processor pair.

PRIMARYPORTNAME number

specifies the Fibre Channel port name (WWN) used by the path to a primary disk

on an Enterprise Storage System (ESS).

The ESS administrator must give you the WWN so that you can specify it in this

attribute.

Enter number as a 16 character hexadecimal number, without a leading %H.

PRIMARYSAC { number | name }
