tapechk(1) — AIX/RT 2.2.1

tapechk

PURPOSE

     Performs  consistency  checking  of  the  streaming  tape
     device.

SYNOPSIS
     tapechk [ ? ] [ num1 [ num2 ] ]

DESCRIPTION

     The  tapechk  command  performs  rudimentary  consistency
     checking  on an  attached  streaming  tape device.   Some
     hardware malfunctions with a  streaming tape drive can be
     detected by  simply reading  a tape.  tapechk  provides a
     way to perform tape reads on the file level.

     Since  the streaming  tape  drive  cannot backspace  over
     physical data  blocks or files, tapechk  rewinds the tape
     to its  starting position prior  to each check.   You can
     specify numeric arguments to  control the number of files
     checked or skipped.  If you do not specify any arguments,
     tapechk rewinds the tape and  checks only the first phys-
     ical block.

     Although you can  use tapechk on any  streaming tape car-
     tridge,  it  is  primarily designed  for  checking  tapes
     written by the backup command.

FLAGS

     num1  Checks data for the next num1 files.
     num2  Skips the next num2 files from the beginning of the
           tape.
     ?     Explains the format of the tapechk command.

           Note:  If you specify this argument, it must be the
           first argument.
