Need your guidance regarding the following:-
An existing 2 node R3 production cluster has the following:-
1. ServiceGuard A.11.16.00
2. SG-NFS-Tool A.11.11.06
3. SG-Ext-SAP-R3 B.04.01
Current OS is HP-UX11iv1 and OE/ReleaseID is HPUX11i-OE, B.11.11.0509.
The requirement is to upgrade the OS to B.11.23.0806, FOE (or later, based on availability of Media).
Need you experts opinion on upgrade considerations for SG, SG-NFS-Tool and SG-Ext-SAP-R3.
Thanks in advance
Solved! Go to Solution.

Re: SG considerations for 11iv1 to v2 upgrade
Go to docs.HP.
download the doc "install and update da da da da"
for each version of product you want to upgrade to. It will be there , how to do that.
Suggestion is to do a cold install!!!

SolutionSo, from here:
http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02466761/c02466761.pdf
page 12, Serviceguard A.11.16 went out of support on HP-UX 11.23 last year.
However, to do the upgrade this is not so important as you can upgrade Serviceguard once the OS upgrade has been completed succesfully, and you should upgrade to at LEAST A.11.18 of Serviceguard at that time.
SGeSAP B.04.01 is also supported on HP-UX 1.23, but once you uopgrade Serviecguard you should consider upgrading the SGeSAP AND the NFS Toolkits to a later version.
Bear in mind that installing these toolkits merely loads them into the /opt/cmcluster directory, and you would need to use the newer files supplied in those locations to modify your existing package configuration and control files.
I would suggest you first do the OS upgrade, and make sure all is well at that stage and THEN consider doing teh upgrade of the Serviecguard and toolkit software

Also for Serviceguard:

I am currently unable to locate one for the NFS Toolkit, but you should always look to use the lates version for the relevant OS and Serviceguard software installed.

Re: SG considerations for 11iv1 to v2 upgrade
My five cents.
If you have Service Guard you should have a cluster of two nodes minimum.
So I will use this aproach:
- Make_tape_recovery for both nodes.
- Pass all packages to one node ( node 1 )
- Halt de node 2 in the cluster
- In node 2 cold install of OS SG and toolkits.
- Regoin the node 2 to the cluster.
- Pass the packages and see if everything is function correctly
- If yes do the same for the other node.
If you have any doubt reply.
Regards.

Re: SG considerations for 11iv1 to v2 upgrade
Major doubt here - Say, Node 1 (11iv1) is having SG A.11.16, NFS-Tool A.11.11.06 & SGeSAP B.04.01. After doing the upgrade in Node 2, let's say it has 11iv2, SG A.11.19, NFS-Tool A.11.11.08 & SGeSAP B.05.00. Will they rejoin into a cluster

Re: SG considerations for 11iv1 to v2 upgrade
I think the answer is yes.
I already do a upgrade similar to yours ( without those toolkits ) and this was the aprouch that I use.
Althought you must check if version's of SG are compatible.
Take in consideration 2 things:
1 - If you use SG_RAC you can't use this aprouch:
"SGeRAC is not supported in a heterogeneous
cluster because Oracle RAC does not support mixing HP-UX versions within a
single RAC cluster."
2 - Have a good backup of the server ( if you need to go back you can easily do it with recovery tape )
Also don't forget to assign some point to usefull answers.

Re: SG considerations for 11iv1 to v2 upgrade
NO they won't!
You CANNOT do a rolling upgrade to A.11.19 from anything below A.11.18.
If you do an upgrade make sure you have S GA.11.16, or at most A.11.17, that should work.
However, if you are looking at doing a cold install, that is NOT a rolling upgrade, and requires different steps
