I have been working the same issue

We think it has come down to a network issue as my throughput cratered to about 300 kbps.

 

My fist thought is look for any network – card, cable, switch issues.

Subject: [Veritas-bu] RMAN and MS-SQL Backup Fail - Error 21

 

Environment:

 

Master is Windows 2003 SP2 x86 running NBU 6.5.3 and clients are a mix of Windows 2000, 2003, x86, x64 running NBU 5.1 MP4 & 5.

 

I've got the oddest issue I've been working two weeks.  Two weekends ago my RMAN and MS-SQL backups began failing with errors 21.  The jobs don't fail right away, and not every job fails.  An RMAN job might write none or all but one of its datasets than fail with Status 21 - Socket Open Error.  Re-runs are generally successful.  I'd say about 30% of all RMAN and MS-SQL backups are failing with this nightly, and its not always the same database or dataset.  I moved the jobs from a media server to the master, and the issue still occurs leading me to believe this is a master server issue.  I've had a case open with Symantec all week and they are definitely seeing errors when the Master goes to open communications with the client to start the backup, but cannot determine why (so far.)

 

Has anyone else ever run into this / have any ideas?  I'm neck deep in Windows registry at this point trying to figure something out but I've got no joy so far.  I've goggled and checked Symantec's site but this doesn't seem to be a common issue.
