MSL2024 SC11Xe Windows 2008 R2 scsi sense error

I'm getting a scsi sense error when trying to backup via ARCserve to a Parallel SCSI MSL2024 1 drive tape library.

The backup starts ok but after a random amount of data I get an "Unexpected SCSI Sense Code" error and the backup job fails.

If I disable the HP Insight Storage Agents service the backup completes at 1.4TB.

MSL FW is 5.00/B59W and PSP v8.60 is installed.

With that service disabled the backup works fine - is that correct?

Do you need that service?
Should it be enabled?

You probably need the registry fix for that controller. There is a registry entry "BusyRetryCount" that must be set to 250 with the SC11Xe whenever the HP Insight Storage Agents are running or anything else that sends periodic commands to the drive.

See http://support.microsoft.com/kb/932755 for details on setting that.

Note that the registry entry should be checked after every firmware update. If the OS creates a new entry for the drive with the new firmware then that value must be created again.

Yes this works fine with the service disabled.

I'll try the reg key and see if that solves the issue. I don't want to keep the service disabled as it reports useful information.

Incidentally I have a W2K3 server with this card and an MSL4048 and I've never had to configure it like this.

I've added the registry key and my backup is still running. Upto 512GB so far.

Just doing another backup to make sure but I think it's resolved now.

Managed to do 2 x 600GB backups so I'm satisfied with that. I could only stream about 20GB to tape previously.

Add REG_DWORD 250 for BusyRetryCount
