This looks pretty much like a scsi bis error. I suggest you check these items
(in this order):
- tape set to a known unused scsi target i.d. (usually 4,5 or 6)
- proper termination of the external scsi bus. In particular, if you are using
wide scsi disks along with a norrow scsi tape drive, the following
conditions
must meet:
- wide devices located near to the host adapter.
- wide/narrow converter must have built in terminator for the upper 8 bits.
- wide scsi cable should not exceed 0.5 meters
- narrow cable between wide devices an tape should not exceed 0.5 meters.
please note: the restrictive cable length requirements are due to the
mixed mode (narror/small).
Good look, Your's Andreas
