Hi All,
Can anyone explain the following problem.
1. rewind tape, dump, rewind tape
2. forward to end of 1st dump, dump, rewind tape
3. Attempt to repeat step 2.
This causes the following error message.
(sa0:ncr0:0:6:0): WRITE(06). CDB: a 0 0 80 0 0
(sa0:ncr0:0:6:0): ILLEGAL REQUEST asc:90,1
(sa0:ncr0:0:6:0): Vendor Specific ASC
Here's a camcontrol inquiry on the device. This is an AIWA TR-5 tape.
pass6: <AIWA TD-20001 0159> Removable Sequential Access SCSI-2 device
pass6: Serial Number 8CB203D1
pass6: 10.000MB/s transfers (10.000MHz, offset 7)
I've included the steps that caused this below. This is under 4.0 stable.
