I am receiving an error when running an arcserve backup on my hp storageworks MSL6050 Tape Drive.

the backups are failing due to 'an unexpected scsi sense code'.

i also have entries in the event log:

- \device\scsi\cpqcissm2 did not respond within the timeout period
- the device detected a controller error on \device\scsi\cpqcissm2


does anyone have any ideas how to resolve this?

thanks.

Control Panel --> HP Management Agents --> move SCSI Information to the right side so it will not be collected.

will this not just disable the scsi connections?
will the backups still run if i do this?

HP Agents collect data for Insight Manager to predict component failure. The collection of SCSI Information can conflict with ARCserve operation of the tape device. Setting it to not collect SCSI Information will not effect the SCSI connections or prevent backups from running.

hi dovid. i've tried that but that backups have failed. do you think upgrading from arcserve r11.1 to r11.5 might help?

maybe upgrading the scsi and tape drive firmware and drivers?

cheers for any iinfo.

It might be necessary to upgrade to 12.0 since 11.5 might not be available.
Yes update the firmware for the tape drive.
Also update the driver for the SCSI controller.
Disable the tape drive from within the OS Device Manager.
If this is a RAID controller check to make sure HP supports tape drives on it and if they do the ck to see if they support both hard and tape drives on the same controller, it might be necessary to put the tape drive on it's own controller.

i've upgraded to arcserve 11.5 and upgraded to HP L&TT 4.6.

Through L&TT, i've upgraded the Libary and Tape Drive firmware.

i successfully ran a full backup at the weekend, so hopefully this will continue to work all week.
