Upgrading 3 members cluster

[Devilmac]

Hi,

I need to upgrade a 3 member cluster from R77.30 to R80.10

Until now i have been using the CP_Conectivity_Upgrade.

Where you upgrade first the two passive members to R80.10 and later the last one.

This time i need to upgrade one by one the members like this:

member1 - R77.30 active

member2 -R77.30 standby

member3 - R77.30 standby

to

member1 - R77.30 down

member2 - R77.30 down

member3 - R80.10 active

to 

member1 - R77.30 down

member2 - R80.10 active

member3 - R80.10 standby

to

member1 - R80.10 active

member2 - R80.10 standby

member3 - R80.10 standby

Do i need to do a cpstop in member2 then follow the CP_Conectivity_Upgrade with member1 and 3. And then upgrade member1 and 2 one by one

Is this correct?

Thank you!

The more pertinent question is why are you upgrading to R80.10 and not R80.30, which is the widely recommended release? Even R80.20 would be a better choice here:

There could be a million reasons why they can't go to a higher version.  Their MDS being on 80.10  comes immediately to mind.

And perhaps they're not ready to upgrade to 80.20 or 80.30.

Sorry for being a little salty with this reply.  I spent 17 hours this past Saturday and 5 hours on Sunday trying to get to 80.30 only to have the installer tank our primary MDS and having to revert a 200 gig snapshot in the slowest possible manner.

I've upgraded a number of 80.10 3-node clusters using the CU method and it has worked just fine.

However, the document I used did not exactly line up with 3 nodes.

With node 1 active, I did a cpstop on node 3.  Then I upgraded node 2.  Then I changed OS version in the cluster object and pushed policy with the "deploy to individual nodes" option.  Then forced the fault as the CU document noted.

Then I went and upgraded the other 2 nodes, pushed policy and every thing worked.

This is what i needed to confirm.

Thanks!
