Now I'm really scratching my head. I purposely left the wrong tape
loaded last night so amdump would have to scan and find the right
one, which it did and ran ok.
Then I set the sleep value down to 5 seconds from the 10 I had there
in chg-scsi.conf just now, and reloaded the magazine with the next 4
tapes.
Either the new drive needs less sleep time, and the reduced sleep time
fixed it, or that group of tapes is going bad as I cannot reproduce
it again. Ahh, wait, the 4th run of amcheck failed, so its still
doing it.
amcheck-server: slot 0: tape_rdlabel: tape open: /dev/nst0:
Input/output error
amcheck-server: slot 1: date 20040317 label DailySet1-15 (active tape)
amcheck-server: slot 2: date 20040317 label DailySet1-16 (active tape)
amcheck-server: slot 3: date 20040317 label DailySet1-17 (active tape)
And
Another run, and it will find it ok. But it will be with a sleep 1 in
chg-scsi.conf.
amcheck-server: slot 3: date 20040317 label DailySet1-17 (active tape)
amcheck-server: slot 0: date 20040209 label DailySet1-14 (exact label
match)
I'm going to reset the crontab to run it every 30 minutes the rest of
the day & see how many emails I get. This is a bit like watching
paint dry. :(
