The SAC Object
The SAC Object
The SAC object represents a ServerNet addressable controller on a storage adapter.
Commands issued for a SAC are often targeted at devices connected to the SAC. For
example, you can use the SAC object to test or display information about:
•
The connection to an arbitrated loop of a Fibre Channel disk module (FCDM)
•
The ports in a Fibre Channel link
•
The SAC itself
For more information, see PROBE SAC Command on page 14-98, STATS SAC
Command on page 14-116, and STATUS SAC Command on page 14-123.
The SAC object has this format:
$ZZSTO
is the storage subsystem manager.
#type
is the adapter type, for example FCSA.
#SAC-n
is the number of the SAC on the adapter.
GRP-g.MOD-m.SLOT-s
is the physical location (group, module, and slot) of the adapter. g cannot have a
leading zero.
Wild-card characters are supported.
Example
$ZZSTO.#FCSA.SAC-2.GRP-111.MOD-2.SLOT-5
The SCSI Object
The SCSI object represents an Open SCSI device, which is a storage device that uses
the small computer system interface (SCSI) to connect the device to the system.
The SCSI object can also represent an Open SCSI Fibre Channel device, which is a
Fibre Channel device that uses the SCSI protocol to communicate with the system
through the Open SCSI I/O process.
Unless stated otherwise, references to Open SCSI devices also refer to Open SCSI
Fibre Channel devices.
