New SQL Server 2000 Install - Backup of Empty Database never compl

We installed SQL Server 2000 SP3 and created a number of databases. However
after a while the backups of these databases appear to hang forever and
required a reboot to clear. We then created a brand new empty database and
tried backing this up, but had the same problem.

Looking in the Event Viewer the following errors:

The device,  \Device\Scsi\aarich1
, did not respond within the timeout period.

We mirrored disks set, so we tried splitting the mirror both ways and
running the backups, but had the same problem.

Looking at the Event Viewer messages for MSSQLSERVER there ar a number:

Error: 17805, Severity: 20, State: 3
Invalid buffer received from client.

18204 :
 BackupDiskFile::Crea
teMedia: Backup device 'w:\tmp\tst1.bak' failed to
create. Operating system error = 3(error not found).

When the  backup hangs the CPU on the server drops off to zero and the
server becomes very unresponsive.

The Operating sytem is Windows 2003

Anyone any ideas?

mikekimber1,

That looks like a hardware problem to me. Have you changed the drivers
recently? If so, it could be a driver problem.

Also check that the location you are backing up to really exists. I know, an
obvious point, but there may be a type somewhere in your code.

Mark.

Is drive W: a mapped drive? Try using UNC (i.e. \\server\share) instead of
mapped drives.

SCSI timeouts are significant enough and they could indicate that there is a
serious H/W problem. You should address them first and then check your
databases for corruption. Use CHECKPOINT, DBCC DROPCLEANBUFFERS and DBCC
CHECKDB to ensure that you are loading clean database pages from the disk.

Microsoft has several hotfixes for 17805 errors, but they are probably not
related to your backups.
