NAME

       ata_scsiop_noop - Command handler that simply returns success.

SYNOPSIS

       unsigned int ata_scsiop_noop(struct ata_scsi_args * args, u8 * rbuf);

ARGUMENTS

       args
	   device IDENTIFY data / SCSI command of interest.

       rbuf
	   Response buffer, to which simulated SCSI cmd output is sent.

DESCRIPTION

       No operation. Simply returns success to caller, to indicate that the caller should successfully complete this SCSI command.

LOCKING

NAME

       vparutil - get and set SCSI parameters for SCSI controllers from a virtual partition

SYNOPSIS

       dev_path

       dev_path

       dev_path scsi_id] scsi_rate]

DESCRIPTION

       The  command gets and sets SCSI parameters for SCSI controllers within a running virtual partition.  When setting the SCSI parameters using
       the option, the virtual partition which owns the specified SCSI controller must be in the down state.  If not, the command will	fail  with
       the appropriate error code.

       The  SCSI parameters for a given SCSI controller must first be set (from the firmware BCH prompt or using the option) before the parameters
       can be retrieved using the option.

       The command is allowed on Itanium(R)-based platforms for compatibility.	No action is taken for the command.

   Options
       recognizes the following command-line options:

       Deletes an entry for the specified SCSI controller at
	     dev_path from the SCSI table.

       Gets the SCSI parameters for the specified SCSI controller at
	     dev_path.

       Sets the SCSI parameters for the specified SCSI controller at
	     dev_path.

   Operands
       recognizes the following command-line operands:

       dev_path        The device path of the SCSI controller.

       id	       The SCSI ID for the specified controller (defaults to 7).

       rate	       The SCSI rate for the specified controller.  This parameter can have one of two values: for the corresponding fast wide and
		       ultra wide SCSI interfaces.

   Note
       For managing SCSI controllers, use corresponding SCSI utilities.  For further information refer to

SECURITY RESTRICTIONS

       This command is restricted to processes owned by superuser.

       When  virtual  partition  flexible administrative capability is enabled, only a Designated-Admin vPar can set SCSI parameters for SCSI con-
       trollers.

EXAMPLES

       Set the SCSI ID for controller at 0/0/2/0 to 3 with the fast wide rate:

RETURN VALUE

       Successful.
       Invalid SCSI controller specification.
       Invalid SCSI ID.
       Could not communicate with virtual partition monitor.
       Virtual partition which owns SCSI controller is not in down state.
       Internal firmware call failed.
       Other error.
