Path Information (for each path)
Adapter the adapter type and physical location (group, module, slot) of
the storage adapter that controls the disk. This value is
retrieved from the system.
Disk Device ID /
Port Name
For an internal disk, the SCSI address.
For a model 45xx disk connected to an adapter, the slot number
of the disk in the modular disk subsystem. This is the address
used by the SAC to access the disk.
For an M8xxx Fibre Channel disk in a disk-drive enclosure, the
(shelf, bay) of the disk drive.
For a disk in an Enterprise Storage System (ESS), the World
Wide Name (WWN) of the disk.
Disk Device LUN always shows a value of zero (0).
Location (Group,
Module, Slot)
the physical location of an internal disk (group, module, slot).
For a model 45xx disk in a modular disk subsystem or a model
M8xx disk in a disk-drive enclosure, Location is the location of
the storage adapter that controls the disk.
SAC Name the name of the ServerNet addressable controller in the
adapter. The name is determined by concatenating the adapter
type, the physical location of the SAC in the adapter, and the
adapter location values. Slots 50, 51, and 53 are on the
X fabric. Slots 52, 54, and 55 are on the Y fabric.
SAC Number the physical location of the SAC in the adapter. For an internal
magnetic disk, this value is either 1 or 2. This value determines
the SCSI bus used to access the internal disk.
For devices connected to an adapter, a value of 1, 2, 3, or 4
depending on how many SACs are installed in the adapter.
