NetBackup version upgrade involving DD and NBU Appliances
Hello Folks, Greetings for the day. We have many small/large NetBackup environments that we would like to start NetBackup version upgrade on. The NetBackup Master Server is a physical server with either Windows or Linux OS on it. We have environments where we have been using Data Domain for short-term backup and then vault them off to tapes for longer retention. In some of our environments, we also have NBU appliances being used as media servers. Many environments have all devices viz. NBU Master Server (Physical Server), NBU Media Server(Physical Server), Data Domain(Appliance), NBU Appliances, Ops-Center(Virtual Machine) in there together. Could you please guide us the correct sequence which should be followed for Upgrading NBU environment to NBU 7.7.3 ? We know the basic sequence of proceeding with Ops-center first, then NBU Master Servers, then NBU media servers, then clients, but the involvement of appliances has been adding complexities to the whole upgradation process, especially when it requires upgrading 3rd party appliancs like Data Domain. I will be furnishing more details about individual's version but at some point, we have found ourseleves stuck up on whether to upgrade DD first or NBU Master Server first. In our environment, we need to upgrade both, the DDOS and DDboost plungin. EMC has suggested to upgrade DDOS to Version on 5.5.4.10 and ddboost plugin to 3.1.x. The upgrade path is 5.0/5.1 to 5.2 to 5.5.4.10. So we are pretty confused as to go with DD OS / DDBoost plugin upgrade first and then NetBackup upgrade on some other day or all to be performed on the same day? Also, can we ourseleves upgrade the DD OS/DD Boost or EMC TSE needs to perform the same ? The NetBackup Master Server version is little different in all of the environments w.r.t patches installed over and above 7.5 version. Ops-center is Ops-Center Analytics ver 7.6.0.1 on VMware virtual machine running Windows 2012 OSmanaging all of the different Master Backup servers. ======================================================= There are many but to start off with, two of our NBU environments have below configuration:-> NBU Environment 1 Data Domain Model number: DD610 Data Domain OS 5.0.1.0-240411 Master Server NBU version installed: 7.5.0.5 Master Server OS : windows 2008 R2 Current plugin installed:- 2.3.1.0-223945 Media Servers: N/A Tape Library/Robot: N/A Data Domain: Configured as single Disk Pool NBU Environment 2 Model number: DD620 Data Domain OS 5.1.1.0-291218 Master Server NBU version installed: 7.5.0.4 Master Server OS : windows 2008 R2 Current plugin Version: 2.4.1.0-289644 Media Servers: N/A Tape Library/Robot: N/A Data Domain: Configured as single Disk Pool ================================================================== Please let me know if you need any more info from our side.
