backupexec... constant checksum error

Hey guys,

I have a windows server 2003 running BackupExec 2010 with an HP StorageWorks backup to tape device.
For months now I have been getting a checksum of data has failed daily and cant figure out what the cause is. I have cleaned the device, new tapes, and updated the drivers and still get this constatn annoying error. It seems when I uncheck the verification process I dont get the error anymore but I dont like doing that.. according to Symantec its a CRC error and I dont know if its a faulty error or something I should be concerned about.

If I go into my event viewer on the server I see the following errors:

Maybe this will help - http://www.symantec.com/connect/forums/scsisymmpi1-error

Please check Windows Event Viewer, in the System event log. Look for any errors on the Symmpi device. While this may be a driver or firmware issue, usually this type of error resolves itself to the SCSI controller card, and would need to be addressed by that vendor. Your mention of the error occurring on random jobs, and at random points, is also indicative of this. If, for example, a backup job itself was corrupt, you would see consistent failures on a certain job, or on a specific resource.

the error happens on each nights backup not random

I would try another scsii card if you can.

Please test the tape drive using HP's Library and Tape Tools, you probably already have L&TT if you used that to upgrade firmware, if not it's here -

Is this something that has recently appeared and if so has anyone changed any settings on the backup server?  This can sometimes be symptomatic of changes in the SCSI controller setting regarding speed and timeout.

andyalder,

You are correct in the assumption that I have the software and it shows that the device is working correctly with no issues. However, the one tab that I am a little unfamilar with and am having difficulty is the firmware tab.  It says, there are no matching firmware files in the currently selected firmware folder" and i dont know where to point it to.

Do you have any idea where I need to point it to?

Not sure about the local folder but can't you tell it to get the latest firmware from HP's FTP site and populate that folder with it? Pretty sure it knows the URL although you can manually get them from ftp://15.216.110.21/ftp2/pub/information_storage/software/ltt/firmware/ (must have a friendly URL as well as the 15... one, I don't know it though).

im changed the driver and still the issue is there..hmm...

Im gonna see if I can change the backup scheudle because that may be causing the conflict due to another backup running during the course of that one.

checksum error is more likely a hardware issue. Either the drive or the scsii card
