raid1 error while rewind tape

raid1 error while rewind tape

[Dirk Jakobsmeier]

Hi you all

i have a big problem with running my backup server with kernel 2.4.21 and a
raid1. Both, the scsi disks and the tape use the same scsi controller.
While i let the system rewind the tape, and if this command needs long
time, the scsi driver from kernel recogizes an error.

kernel: scsi : aborting command due to timeout.
kernel: SCSI disk error
kernel:  I/O error
kernel: raid1: Disk failure
kernel: ^IOperation continuing on 1 devices
kernel: md: updating md2 RAID superblock on device
kernel: md: recovery thread got woken up
kernel: md2: resyncing spare disk
kernel: RAID1 conf printout:
.
.
.

Is there a possibility to handle this problem, or do i have to install a
second scsi controller?

Thanks for any help.

Dirk

You might want to check the FAQs for info on "SCSI disconnect" support. 
Most modern SCSI tape drives support this, but without any configuration 
details on the tape drive or the host adapter, it's hard to say whether 
it will work for you.

Chances are that more people will have answers on one of the 
SCSI-specific lists.
