he host is connected through an LSI scsi card (LVD) to a VXA Packet loader.
The details displayed in /var/log/messages is nothing like the exmaple from
the tape test notes. Command tapeinfo output also seems odd. Variable block
doesn't last, it very quickly returns to 1024.
Any config ideas or setting changes would be very welcome
