Backup Exec SCSI Timeouts
Posted on 2007-10-19
I've been having problems with our backups now for nearly 6 months. We keep getting SCSI timeout errors when using Dell Poweredge servers, Adaptec 29160 SCSI card and BE 11D.
Backup Exec Alert: Job Failed
(Server: "WINCH-BH") (Job: "AvanquestUK BUP") AvanquestUK BUP -- The job failed with the following error: The block size being used is incorrect.
The device, \Device\Scsi\adpu160m1, did not respond within the timeout period.
he description for Event ID ( 11 ) in Source ( Over_SLR ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: \Device\MediumChanger0.
The backup will run for a random amount of time and then fail, although it will sometimes complete. We have changed everything in the SCSI chain. Card, cable, terminator, Drive and loader.
Firmware and drivers on everything are the latest. We originally built BE on an Dell1850. As a test we then built a temp desktop machine to see if it was the server at fault. We have ran two backups on the test machine both over 900GB and have yet to have a timeout.
I then built another Dell server, this time a 2850 as the production server. Thinking that it was a problem on the original servers hardware. As soon as I ran a backup on this server we received the above errors.
I'm currently running backups on the test server again.
Has anyone got any ideas why our jobs would fail on the Dell servers?
Each machine has the same setup 2003 Server Standard SP2 and backup Exec 11d SP1. .
Please let me know if you have any suggestions?
