Hi again do you run amcheck prior to amdump running. or is it a simple caseof just hacking your script as below:

#!/bin/sh
# Script lfdom.sh
# Last friday of the month script
if [ `cal | awk 'NF >= 6 {print $6}' | tail -1` -eq `date +%d` ]

then su -c "/usr/sbin/amcheck MonthlySet1"; su -c "/usr/sbin/amdump MonthlySet1" else su -c "/usr/sbin/amcheck DailySet1"; su -c "/usr/sbin/amdump DailySet1"

fi

amcheck is used to check for a valid tape and warn the sysadmin
if there is some problem.  Therefore, I run it during the day, when
I'm still there to correct things.
I do not run any additional amcheck just before launching the  amdump
program in the night.

Therefore, I have two entries in my crontab.
One for amcheck, running at 16:15 Mon-Fri (in the hope that any
problems that might pop up can be still be solved before I go home.
Then another entry that just does amdump, running at 00:05 (yes, that's
actually the next day -- beware if you run the last-friday-of-month
check, in that case, start amdump just a few minute earlier, like 23:55).

Cheers
