Ok, that rules out a problem I encountered with Emulex HBAs. Instead I
know installations with qlogic HBAs, though these don't use IBM
libraries, so my reference configurations won't help us here.

Ok, fairly recent.

Well, not absolutely up-to-date, but I don't know why this shouldn't
be ok. Note that 2.3 is a development version, so you might consider
upgrading to the latest released version 2.4.something.

As suggested by Simon, I also recommend trying your backups with the
default driver.

The configuration looks ok (note you'll have to change the "Archive
Device" when you switch to the standard driver - it should become
/dev/nst0, usually.

Ok, so we're probably seeing a problem with Baculas way to operate the
tape drive, not the kernel side of things.
