Do you have parity enabled or disabled consistently on that SCSI bus? I.e. all devices have parity enabled or all have it disabled, including the HA. Parity enable on this drive is jumpers 7 and 8, next to the three address bit jumpers. Parity enable in the 2940 is via the BIOS firmware.
Ok, the parity error is now fixed. I had parity enabled in the BIOS and disabled on the drive. The parity error is now gone.
However I still can't get to the tape drive. I tried both the new and old drivers.

Also, you have firmware rev 1.17. You might want to upgrade it. I seem to recall problems with 1.17. I have 1.22, and there may be even more recent firmware.
I'll try that next.
Now I remember why I avoid SCSI...
