I've always upgrade powerha and AIX on nodes of a cluster OFFLINE, I mean, shutdown applications, stop cluster services, upgrade all software from nim, reboot and start again all applications, but now it's time to upgrade our PRODUCTION cluster and we want to do it with the less downtime possible.

The cluster is built with two nodes AIX 6100-07-04 and powerha 6.1 SP8 and we want to upgrade to AIX 6100-07-06 and powerha 6.1 SP10. I have read about the "rolling migration" but not sure how to do it that way. What we need is the less downtime possible.

Thanks.

Hi,

PowerHA 6.1 SP8 is compatible with AIX 6.1 TL7 SP6, so I think the way to go is this:

1) nimadm upgrade of AIX (if you have a free disk, that is).

2) the required  (inevitable) reboot at a convenient time. <-- Downtime!
--> the old PowerHA version will start just fine after the reboot.

3) a rolling PowerHA migration to 6.1 SP8.

Stop the cluster services on one of the nodes with "Unmanage Resource Groups",
upgrade PowerHA, then start the cluster services with "Manage Resource Groups Automatically".
Once you're done on the first node do the same on the second one.

hello wmp.. why do you say that "PowerHA 6.1 SP8 is compatible with AIX 6.1 TL7 SP6"?
Is there any matrix of versions of powerha/AIX?

Yep.

In fact, all flavours of PowerHA 6.1 are compatible with all versions of AIX 6 TL2 SP1 and up with RSCT 2.5.4 and up.

perfect!

Just one thing, when you say " nimadm upgrade of AIX (if you have a free disk, that is)." I can do it mounting the filesystem with aix61tl7sp6 via NFS and update AIX..no?

Thanks once more because your solid answers (maybe one of the best expert here :))

OK,

I recommended the alternate disk installation method because its really the robustest way of upgrading.

Of course you can always do a normal upgrade by means of standard NIM operations.

But why would you still insist in exporting/mounting things by hand? I thought we've been talking about this in the past!

The NIM server will do all the export stuff for you, and the NIM client will do all the mounting. Don't touch NIM filesystems!

On the client just run "smitty nim_c_update_all", select the appropriate LPP source, say "Yes" to "Accept licenses" and Go!

No exporting, no mounting.

ok..  I know that but the fact is this nim server is not up2date with lpp_reseources with the one I'm going to use, so I downloaded tl6sp6 to do this job, but you are sure 100%...
