MSL6050 Tape Drive - unexpected scsi sense code

[paul sharkey]

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.
