We plan to upgrade SG to version A.11.16.
1. Can we upgrade one node while all the packages are failover to the other node ?
2. Can we have different versions of SG in cluster ?
3. New version of SG A.11.16 comes from a Bundle OS 11i OE-MC, do we need a special version of SG for 11.00 ?
4. What about license, any step requires new license for new version ?
5. Does anybody have step by step procedure for the upgrade ?
I will assign 10 points to the best answers.
Thanks,
Rico Cebiche

Re: Upgrade Serviceguard from A.11.09 to A.11.16
1. Yes, there will be a short downtime because the cluster will not work with mixed versions in the node.
2. No.
3. Yes
4. If you have software support on 11.09 you will be able to activate and use 11.16. If you have access to it on the 11i OS, there are no futher barriers to use. The software is normally codeword protected.
5.
1. Back up existing configuration and package scripts.
2. swremove old SG.
3. swinstall new SG.
4. cmquerycl, build a new cluster. Modify inetd.conf as needed.
5. cmcheckconf your new configuration
6. cmapplyconf
cmhalt node the 11.09 node while running steops 4-6.
Document with some details.

Re: Upgrade Serviceguard from A.11.09 to A.11.16
Second point, SG 11.09 WAS supported for HP-UX 11.11 ( support for 11.09 ended about two years ago)
Third point, mixed SG and OS versions are supported ONLY during a rolling upgrade OR for SG 11.09 with mixed HP-UX 11.00 and 11.11
So my suggestion would be to do the HP-UX upgrade first, and use SG 11.09 to get the cluster stable and working, and then upgrade SG to 11.16
Or upgrade the cluster first to SG 11.14 which is the last supported version for HP-UX 11.00, get that stable, then do the OS upgrades, then upghrade SG to 11.16

Re: Upgrade Serviceguard from A.11.09 to A.11.16
Do I have to uninstall A.11.09 before installing A.11.14 ?, or the new version recognizes old version and updates configuration ?
Anyway I am doing a previous ignite tape recovery.

Re: Upgrade Serviceguard from A.11.09 to A.11.16
Steve, seems that you are wrong, you suggested to uninstall A.11.09 before.
This confuses me since both of you seem to be experts in this area.
I am willing to hear a third opinion.
Also, I found a reference to the command:
/usr/sbin/convert -f cmclconfig, I could not find any man page about this command, can somebody explain me what it is for ?

Re: Upgrade Serviceguard from A.11.09 to A.11.16
Upgrade from A.11.14 to A.11.16 will be done during OS upgrade using Update-UX.
This is matter of another discussion.
