Hi Mecki,
  In our case, the ADSM server directory is not part of the root volume
group, so that a mksysb won't grab it.  We also time our operations so that
the volume history file backup contains a reference to our nightly full
backup of the ADSM database, and mksysb just isn't a good fit.

  The actual message we get is "/dev/rmt1.1 fsf 2 failed: There is an input
or output error.", which results from the AIX command "mt -f /dev/rmt1.1 fsf
2".  The mt command is used used to get past the tape label.  I gather that
either an EOF or EOT mark is not being written by the ADSM "label volume"
command.

Thanks,
Jim
