Irwin tape drive (10 meg) & Sco Xenix 286 2.2.3

[G. Simon Gales]

I'm trying to get my Irwin 10meg tape drive to function on my work computer
under Xenix 286, version 2.2.3.  The drive does fine under DOS, but a Xenix
format always fails eventually (ioctl fails on track 8 (9?)).  I am using 
bulk-erased tapes. 
After starting the format, the servo write appears to be done successfully 
(format spins tape silently for 15-20min).  Then the 'formatting track ##'
appears, but I get an error message just after it starts to format track 9.
Writing to a formatted (???) tape only produces write errors.

Does the Irwin drive only work under 2.3?  Noone at work can find a new set
of 2.3 disks, so for now I'm stuck at 2.2.3.
