may it have anything to do with sharing the scsi controller between the
disks and the tape? i know FC has problems with that (and in fact i'm
almost sure that the ts3200 that keeps going offline in my bkp server is
due to that)...

What's everybody else's experience before/after a large save?

If I had as few as dozens of errors on a new tape I'd have a CE looking
at the drive.

On the 52 tapes that I have in regular rotation, I have zero temporary
read errors and zero temporary write errors. The TS2900 drive is about
18 months old; the LTO3 tapes are about 6 years old. We save 600-700GB
each night on these tapes.

There are another 20 or so tapes which get rotated in on a less regular
basis. They too are free of temporary read and write errors. These
tapes are even older than the regulars.
