Error "0512-044 tctl fsf failed"

Environment

Problem

While running a mksysb with a 4mm tape on a J40, the following error is received:

   0512-044 tctl fsf failed

Solution

In AIX Version 4.3.2, a rewind before the chdev was removed. Adding this rewind allows the tape to match up, and the command tctl -f /dev/rmt0.1 fsf 3 does not fail.

The APAR IX88931 corrects this problem. The following is a temporary workaround.

1. Make a backup copy of the mksysb file. Enter:

      cp /usr/bin/mksysb /usr/bin/mksysb.bak
   

2. Open the mksysb file. Enter:

      vi /usr/bin/mksysb
   

3. In the mksysb file, search for make_bootape. At the second occurrence, there should be a line that reads:

      Make first 3 images on tape (boot, bosinst, toc
      make_bootape $TDEVICE
   

   Under the line shown above, insert the following:

      ${tctl} -f $TDEVICE rewind
