Hi Folks,
Netbackup Platform: 6.5.1
OS: HP-UX 11.11
We have one master server which is 6.5.1 and runs around 6000 - 6500 jobs daily and backup approx 40 TB daily. Before upgrading I had checked all the lernel parameters as per installation guidelines and found all of them to be more than what has been recommended.
After upgrading from 5.1 MP5 to 6.5.1 we found three major issues.
1) the nbpem either dies or core dumps every couple days.
2) the NB_dbsrv process takes a lot of CPU.(Almost always 100%)
3) it is taking a long time to dismount/ mount tapes during peak backup window.
Symantec suggested to upgrade Netbackup to 6.5.3. Have any one has faced similar issues? If yes, has upgrading to 6.5.3 resolved the issue.
I also heard from one of my ex-colleague that in his setup(Solaris 10), the server crashes every couple of days after upgrading to 6.5.3. Has anyone else had seen this issue.
Thanks,
Subhojit.
