AMMT(8) 						      System Manager's Manual							   AMMT(8)

NAME

       ammt - Amanda version of mt

SYNOPSIS

       ammt [ -d ] [ -f|-t device ] command [ count ]

DESCRIPTION

       Ammt  provides just enough of the standard mt command for the needs of Amanda.  This is handy when doing a full restore and the standard mt
       program has not yet been found.

       Ammt also provides access to the Amanda output drivers that support various tape simulations.

       See the amanda(8) man page for more details about Amanda.  See the OUTPUT DRIVERS section of amanda(8) for more information on  the  Amanda
       output drivers.

OPTIONS

       -d     Turn on debugging output.

       -f device
	      Access tape device device.  If not specified, the TAPE environment variable is used.

       -t device
	      Same as -f.

       command count
	      Which command to issue, and an optional count of operations.

COMMANDS

       Each command may be abbreviated to whatever length makes it unique.

       eof|weof count
	      Write count (default: 1) end of file marks (tapemarks).

       fsf count
	      Skip forward count (default: 1) files.

       bsf count
	      Skip backward count (default: 1) files.

       asf count
	      Position to file number count (default: 0) where zero is beginning of tape.  This is the same as a rewind followed by a fsf count.

       rewind Rewind to beginning of tape.

       offline|rewoffl
	      Rewind to beginning of tape and unload the tape from the drive.

       status Report  status information about the drive.  Which data reported, and what it means, depends on the underlying operating system, and
	      may include:

	      ONLINE Indicates the drive is online and ready.

	      OFFLINE
		     Indicates the drive is offline or not ready.

	      BOT    Indicates the drive is at beginning of tape.

	      EOT    Indicates the drive is at end of tape.

	      PROTECTED
		     Indicates the tape is write protected.

	      ds     Device status.

	      er     Error register.

	      fileno Current tape file number.

	      blkno  Current tape block number file.

	      NOTE: many systems only report good data when a tape is in the drive and ready.
