Problem with SCSI communication between Adaptec and Ecrix VXA1

Problem with SCSI communication between Adaptec and Ecrix VXA1

[Jan Marek]

Hello lkml,

I have problem in the communication between Adaptec:

02:09.0 SCSI storage controller: Adaptec AIC-7892B U160/m (rev 02)

which is driven by aic7xxx driver.

Kernel version is 2.6.13.1

Tape is ECRIX:

  Vendor: ECRIX     Model: VXA-1             Rev: 2C8C
  Type:   Sequential-Access                  ANSI SCSI revision: 02

I've found in the logs this messages:

Please, can you advice me, where is problem? I have changed SCSI cable
with proper active terminator...

Thank you very much.

Sense Key 0x4     = Hardware error
ASC 0x44/ASCQ 0x0 = Internal Target Failure
ASC 0x15/ASCQ 0x1 = Mechanical Positioning Error
