I'm taking over this 'ticket' from a previous technician.

I think the issue I'm experiencing is part of a larger issue, but I do have a few questions as I am not fully familair with ArcServe.

We are running Arcserve 11.1& HP VS80 external DLT Drive
HP Proliant DL 380 G3 server.
-Data Transfer Rate Averages about 6MB/min.
-This is a local backup.
-Can stop job, but after trying to erase the tape, the software begins the erase but seems to hang.
--I try to stop the engines, cannot stop the Tape Engine.
-Drivers and Firmware are up to date

Thanks in advance

I verified there are no resource conflicts with the DLT and other SCSI devices, but noticed that the DLT has a SCSI ID of 6, while the SCSI Drives have an ID of 4 and 5, repectively.

Shouldn't the DLT drive have a lower SCSI ID than the SCSI drives? Could that cause the speed issue?

I'm going to reinstall this weekend to help rule out a bad installation of ArcServe.
 
Hi,

You may want to verify that the DLT and SCSI Drives are disabled in Windows Device Manager (BrightStor requires explicit access to these devices).

HP Management Agents can also cause issues with the SCSI bus. Use Control Panel to configure the HP Management Agents to remove the SCSI agent from the active agent listing.

Hope this helps!

Best regards,

Gary
 
When I look on a few similar servers, the tape unit is not disabled in Windows Device Manager, and that backup runs fine on these machines.
 
1) Read the faq in the Computer Associates: ARCserve back-up forum on Which Driver to use.
2) If you did a Long Erase then yes it will take a long time and yes it will seem to hang. The Long Erase is the real SCSI Erase command. It tells the drive to postion the tape to the begining and then erase the tape. It will erase the whole tape and it will not accept any other commands until it has finished.
3) Install the latest Tape Engine update and the throughput should go up.
4) Hard drives usually have lower IDs, starting with 0 & 1.
5) It is not a good idea to mix hard drives and tape drives on the same bus. The SCSI bus runs at the lowest common denominator. Fast hard drives, slower tape drive does not mix well.
6) Sooner or later, regardless if you see it or not, OS tape device drivers will cause a problem for ARCserve.
 
I went in on Sunday to do the s/w uninstall and reinstall with updates. Tested backup and everything went fine.

Thanks for your help everyone. I agree with your point, this server should have been set up with a different controller for the Tape drive, but I'm not the 'owner' of this, I did recommend it though.

Thanks again

DP Rello
