DETERMINING AND SETTING THE CONTROLLER MODE

   The Smart Array P411/256 controller has two operating modes:

     o Use RAID mode to take advantage of hardware-based fault-tolerant data
       storage methods such as RAID 1, RAID 1+0, or RAID 5. This reduces the
       amount of available storage space. RAID mode is supported on HP-UX and
       Windows; it is the required operating mode for servers running
       Windows.

     o Use HBA mode to access raw disks for increased storage capacity, to
       allow fault-tolerant storage to be managed by the enclosure firmware,
       or to implement software-based RAID modes using a volume manager.

       [Important] Important:                              
                   SATA disks are not supported when the Smart Array
                   controller is in HBA mode.              

   Use the saupdate.efi command with the get_mode and set_mode options to
   query or change the mode of the Smart Array P410i and Smart Array P411
   controllers to HBA or RAID. Querying or changing modes is not supported
   for other controllers.

GET_MODE

   This option displays the current mode of the controllers.

    Syntax

   saupdate get_mode <controller>

   <controller> can be any one of the strings listed in Table 1.

   Table 1 <controller> strings

   +------------------------------------------------------------------------+
   | <controller>       | Meaning                                           |
   |--------------------+---------------------------------------------------|
   | <seg:bus:dev:func> | A controller having the PCI segment id, bus id,   |
   |                    | device id and function id is addressed            |
   |--------------------+---------------------------------------------------|
   | all                | Addresses all controllers in the system           |
   |--------------------+---------------------------------------------------|
   | <model>            | Controllers of a particular type indicated by the |
   |                    | <model> string are addressed                      |
   +------------------------------------------------------------------------+


SET_MODE

   [Important] Important:                             
               If you are using HBA mode, do not install any disk that has
               previously been a part of a RAID volume into the system.

   Use set_mode to change the mode of the controller. If the controller is
   already in the required mode the following message appears:

   The controller at <seg:bus:dev:func> is already in HBA|RAID mode

    Syntax

   saupdate set_mode <controller> <hba|raid> [-f]

   <controller> can be any one of the strings listed in Table 3-1.

   An alert message about the possible data loss is displayed when a mode
   change command is issued. A confirmation is required before the actual
   mode change is made. This ensures that an unintentional change of mode
   does not happen.

   The -f indicates the user is aware of the changes that are being made, and
   no warning message or confirmation regarding the mode change is needed.

   set mode

   [Note] Note:                                  
          Commands are not case-sensitive. A system reset is not required
          after a mode change.                   

   [Note] Note:                              
          After changing the mode, perform a reconnect -r command at UEFI.
