I wonder if someone can tell me: what kind of error is the
following?
Unexpected busfree. LASTPHASE == 0x0
SEQADDR == 0x5e
And what do I do with it?
It appears rather often while dump'ing on a SureStore DLT40 SCSI
tape connected to:
ahc0: <Adaptec 2940 Ultra2 SCSI adapter> rev 0x00 int a irq 11 on pci0.15.0
ahc0: aic7890/91 Wide Channel A, SCSI Id=7, 16/255 SCBs
The connection is not direct but thru an external SCSI drives case
which contains three hard disks:
da0: <IBM DMVS36V 0100> Fixed Direct Access SCSI-3 device
da0: 40.000MB/s transfers (20.000MHz, offset 31, 16bit), Tagged Queueing Enabled
da0: 35003MB (71687340 512 byte sectors: 255H 63S/T 4462C)
The tape is detected as:
sa0 at ahc0 bus 0 target 1 lun 0
sa0: <Quantum DLT4000 D069> Removable Sequential Access SCSI-2 device
sa0: 10.000MB/s transfers (10.000MHz, offset 15)
