The Netbackup has been upgraded from Rel 5.1 to Rel 6.5. The oracle RMAN backups use 3 channels. It started failing with the following errors after the upgrade. It was working perfectly OK with 3-channels on Netbackup Rel 5.1.

 

I found a temporary work around - Instead of three channels, if I use only one channel, it works.

Single channel takes a long time to complete as it is a large production database. We need multiple channels to work as in Rel 5.1.

 

Is there a permanent fix for this (other than going back to Rel 5.1)? Could someone help?

Hi Tom,

 

I was having the same issues over here, we have basically the same backup platform as yours. Two SL3000 with five IBM LTO4 drives in each one running on NetBackup 6.5.4, this problem was driving me nuts, I've done a lot of firmware upgrades until I fixed this a couple of weeks ago.

 

First you gonna need this:

 

http://sunsolve.sun.com/search/document.do?assetkey=1-21-128549-06-1

 

Update your drives with this firmware, using IBM Tape Diagnostic Tool (ITDT), you can find it on:

 

http://www-01.ibm.com/support/docview.wss?rs=1154&context=STCZU45&dc=D410&uid=ssg1S4000662&loc=en_US&cs=utf-8&lang=en

 

Then open a support ticket with SUN, to update your SL3000 firmware to at least 2.35 release. remembering that firmware updates are user applicable only on the drives.
