- The simplest way is to unmount /home and then do the mksysb. It will

- The way you do this depends on the level of software you are running.
- Based on a couple of things you said in this post, I am assuming that you
- are running a 3.2.x system. If it has 3.2.0, 3.2.1, or 3.2.2 level of AIX on
- it, then make sure the tape drive is set to 512 byte blocks and try the
- following:
-
- tctl -f /dev/rmt0.1 fsf 3
- tar -xf <filename>
-
- You seemed to indicate that this did not work for you. I have never had
- a problem with it.
