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. :( >Sounds weird, but its true.
