Netbackup Upgrade Questions
Hi,
I've been given the task of upgrading a clients environment from 7.0.1 to 7.5.0.7. Never touched upgrades before so been digging round and reading various documents and getting totally confused with it all. So thought would post a question here and see if anyone could offer some assistance with a couple of things.
One of my main issues is identifying the difference between an actual Media server and Enterprise Client server (Think thats the right name)? There are several hosts in the Host Properties -> Media Server section of the GUI but i understand that doesnt actually mean they are all media servers? So is there an easy way to do that? I read something about using nbemmcmd but given my general lack of netbackup knowledge i am not comfortable in trying to interperate command output unless its blindingly obvious? And i guess if you do have multiple media server do you need to do them all or can you run them on different versions as long as they are not on a newer version than the master server?
When you upgrade a Master or Media server is there any post upgrade migration work that needs to be done. the 7.5 Upgrade guide suggest a load of post upgrade migration work of images but is that an internal netbackup process because we are not changing of the actual infrastructure, just the software versions.
Think those are the 2 most pressing issues im trying to get to the bottom of at this moment. So if anyone could offer any insight/advice to help stop me wanting to declare war on all things Netbackup related it would be appreciated.
Thanks
Hi,
Easiest why to figure out who is a MS or an EC is to look at the storage units (either in the GUI or CLI - bpstulist). If its in the list it is either MS/EC and it requires the server software to be used when upgrading it.
If you want to go further and determine which ones are EC then you'll need to check the policies. EC can only back themselves up, so the client would match the storage unit (hopefully your naming indicates the host). The client would also be the only one listed in the policy.
Yes you can do it in a phased manner. OpsCenter first, then master, then media server/enterprise clients, and clients as and where needed.
The post upgrade stuff like image conversions only runs with the master server upgrade.
hope that helps.
If you are to do the master and media server, use Syamtec's SORT tool. This tool will ask you a series of detailed questions about your environment and generate a decent upgrade plan/checklist. The more information and detail you put into it the better the checklist will be.
