1  –  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

1.1  –  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.

1.2  –  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

2.1  –  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.)

2.2  –  Qualifiers

2.2.1    /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.

2.2.2    /LED 

       /LED=OFF
       /LED=ON

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

2.2.3    /REMOVE 

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

2.3  –  Example 

     SAS> SET DISK 1 /LED=ON

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

3  –  UNIT 

    Modifies IR volume characteristics.

    Format

      SET UNIT  volume_id

3.1  –  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.)

3.2  –  Qualifiers

3.2.1    /ACTIVE 

    Activates the specified IR volume.

3.2.2    /CACHE 

       /CACHE
       /NOCACHE (default)

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

3.2.3    /DISABLE 

    Temporarily disables all IR volumes on the SAS Controller.

3.2.4    /ENABLE 

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

3.2.5    /INACTIVE 

    Deactivates the specified IR volume.

3.2.6    /LED 

       /LED=OFF
       /LED=ON

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

3.2.7    /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.

3.2.8    /SYNCH 

       /SYNCH
       /NOSYNCH (default)

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