1  SET
 

2  CONTROLLER
   Selects the default controller specified by the device name.

   This command is required before entering all SAS utility commands
   except SHOW CONTROLLER and SHOW VERSION.

   Format

     SET CONTROLLER  device_name
 

3  Parameters
 

device_name

   The device name has the format ddcu,
   where:

   dd       is the device code.
   c        is the controller designation A through Z.
   u        is the unit number (0 through 9999).

   To display device names, enter the SAS command SHOW CONTROLLER.
 

3  Example

    SAS> SET CONTROLLER PKA0

    Selected Controller _PKA0: is a LSISAS10XX device.
    SAS>

     In this example, controller _PKA0: is selected as the default
     controller.
 

2  DISK
   Modifies physical disk properties such as turning the Locate LED
   on or off and specifying the unique device ID (UDID) to external
   SAS and SATA devices.

   Format

     SET DISK  sas_id
 

3  Parameters
 

sas_id

   Specifies the SAS ID of the target SAS disk to be modified. (To
   display SAS IDs, enter the SAS command SHOW DISK.)
 

3  Qualifiers
 

/IDENT

      /IDENT=udid

   Specifies the unique device ID (UDID), which is used as the unit
   number in the device name for an external SAS or SATA disk. The
   device name is in the form $3$dgaxyz, where xyz is the UUID for
   external SAS and SATA disks.

   The UDID can be a number between 1 and 9999.

   See the /REMOVE qualifier to remove a UDID.
 

/LED

      /LED=OFF
      /LED=ON

   Sets the Locate LED, which can be used to find the SAS or SATA
   disk.
 

/REMOVE

   Remove the unique device ID (UUID) for an external SAS or SATA
   disk.
 

3  Example

    SAS> SET DISK 1 /LED=ON

     In this example, the SAS ID 1 Locate LED is turned on.
 

2  UNIT
   Modifies IR volume characteristics.

   Format

     SET UNIT  volume_id
 

3  Parameters
 

volume_id

   Specifies the IR volume ID of the IR volume to be modified.

   (To display all IR volume IDs in the SAS Controller, enter the
   SAS command SHOW DISK or SHOW UNIT command.)
 

3  Qualifiers
 

/ACTIVE

   Activates the specified IR volume.
 

/CACHE

      /CACHE
      /NOCACHE (default)

   Specifies write caching to a physical disk. Write caching is
   turned off by default.
 

/DISABLE

   Temporarily disables all IR volumes on the SAS Controller.
 

/ENABLE

   Enables all IR volumes previously disabled by the /DISABLE
   qualifier.
 

/INACTIVE

   Deactivates the specified IR volume.
 

/LED

      /LED=OFF
      /LED=ON

   Sets the Locate LED for all physical disks on the IR volume to
   off or on.
 

/SPARE

      /SPARE=sas_id

   Specifies the disk SAS ID to be added as the Global Hot Spare
   disk. (The SAS ID is the ID displayed when you enter the SAS
   command SHOW DISK.)

   This qualifier is required only when specifying a Global Hot
   Spare disk for a RAID 1 configuration.

   You can configure one Global Hot Spare disk per controller. The
   spare drive can be shared between two RAID 1 IR volume sets per
   controller. The size of the disk specified as /SPARE should be
   equal to or greater than the size of at least one of the physical
   disks on the IR volume.
 

/SYNCH

      /SYNCH
      /NOSYNCH (default)

   Specifies the use of high-priority or low-priority
   resynchronization. High-priority resynchronization is off by
   default.
