We've experienced similar problems with AIT3 drives. We upgraded from
6.1.3 to 7.1.
I've got a call placed through our Software maintenance people with
Legato. As yet I haven't had an answer, although turning the CDI
interface off was mentioned, but that didn't seem to help.

Subject: [Networker] SDLT write errors with Networker 7.1


We've ugraded our Solaris Networker server from 6.1.2 to 7.1.   All
seems
fine except we seem to be getting many more SCSI media write errors now
on our SDLT 220 tapes.   The errors show up in Networker as "bad file
number"
errors" :

With no drive in common for the errors it would appear this version of
Networker is having problems with our media. Is anyone using SDLT drives
with Networker 7.x successfully without errors like this?   Could this
be
related to the new CDI system of networker 7.x or is it suddenly bad
media?

Also, this tape was being written during cloning.  This version of
Networker now leaves the nsrclone process hung along with the tape being
read.  Sigh.
