Hi All,
	Attached are the latest changes I've made to 'scu'.  Nothing earth
shattering, just a couple commands to help lookup status codes to make
debugging a little easier.  Since all these tables exist inside 'scu', it
seemed to make sense to add commands to display them (rather than searching
include files, etc).

	Latest versions in:

		wasted:~rmiller/nscu.d/{scu,scu-ptos,scu.hlp}

	You can also download these from my web page via URL:

		http://www.zk3.dec.com/~rmiller/scu.html

	Hope you find'em useful.

Cheers,
Robin

	------------------------------

     o	Added a "show cam status" command:

  This command displays the message associated with the CAM status value.
  Device nexus information is not necessary for displaying status messages.

  Format:

    scu> show cam status value

  Examples:

    % scu show cam status 0xa
    CAM status = 0xa = CAM_SEL_TIMEOUT - Target selection timeout
    % 
    % scu show cam status 0x13
    CAM status = 0x13 = CAM_UNEXP_BUSFREE - Unexpected BUS free
    % 

     o	Added a "show scsi" command:

  This command displays the SCSI message associated with bus status,
  sense key, and sense code/qualifier.  These commands are useful when
  you have a hex value, from say an analyzer or an error message, and
  wish to see what the value translates to.  Device nexus information
  is not necessary for displaying status messages.

  Format:

    scu> show scsi { ascq value | key value | status value }

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

  This command displays the message associated with the two byte sense
  code/qualifier value specified.  The value expected contains the
  sense code in the upper byte, and the qualifier in the lower byte.

  Format:

    scu> show scsi ascq value

  Examples:

    % scu show scsi ascq 0x0401
    Sense Code/Qualifier = (0x4, 0x1) = Logical unit is in process of becoming ready
    % 
    % scu show scsi ascq 0x2800
    Sense Code/Qualifier = (0x28, 0) = Not ready to ready transition (medium may have changed)
    % 

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

  This command displays the message associated with the sense key value
  specified.

  Format:

    scu> show scsi key value

  Example:

    % scu show scsi key 6
    Sense Key = 0x6 = UNIT ATTENTION - Medium changed or target reset
    % 

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

  This command displays the message associated with the SCSI status
  value specified.

  Format:

    scu> show scsi status value

  Example:

    % scu show scsi status 0x28
    SCSI Status = 0x28 = SCSI_STAT_QUEUE_FULL = Command tag queue is full
    %
