I have a two node cluster ( with oracle packages and Oracle Rac configured ) in hp-ux 11.11 with SG version A.11.16.00.
I want to do a upgrade to hp-ux 11.23.
I need to use the rolling upgrade
I will do the followins steps:
cmhaltnode -f node 1
Upgrade node 1 to 11iv2 with upgrade-ux
cmrunnode node 1
cmhaltnode -f node 2
Upgrade node 2 to 11iv2
cmrun node2
I have two questions, is this procedure safe ? ( anyone already try it )
Do I need to upgrade me SG version to the last one ?
Thanks in advance for the reply's.
Regards

SolutionNo need to upgrade SG version
1 Your procedure for upgrade is fine but take ignite backup.
2. Without ignite backup you can not rollback your OS to 11.11.
3. There are some other considrations also while upgrading OS from 11.11 to 11.23 like
Firmware version's of PDC/BMC
Disk space requirments for 11.23
os release etc

Re: Rolling Upgrade
Any experienced system administrator would not use upgrade-ux.
What I would do is this:
Migrate all services to one node.
Do a cold OS install of 11.23
Install all needed applications including Serviceguard.
Schedule a down time to shut down the entire cluster and migrate services to the newly installed node.
Repeat the above on the second node.
Oracle does not support the use of upgrade-ux to upgrade the OS. People with experience support cold install of the OS.

Re: Rolling Upgrade
If you are Using Two Oracle version than ?
Means Currently you are running with Oracle version 9 & you want to install oracle 10G as well is same box, than again you need to instal both, but if you upgrade it I think no harm in that.
I have done upgrade from 11.11 to 11.23 recently without any issues.

Re: Rolling Upgrade
1) Move all packages to node2 (cmhaltnode -v -f node1)
2) Update the os
Read the SG release notes. Older versions wont allow the COLD install, bcoz of changes to the instance numbers.
if you want to do the cold install, then print a full listing of ioscan prior to install. After this you can alter the instance numbers)
3) Apply patches, Kernel params, ioscan, insf -e
4) Install SG and patching
5) turn on auto cluster config /etc/rc.config.d/cmcluster
AUTOSTART_CMCLD=1
5) cmrunnode -v
Repeat for the other node

Re: Rolling Upgrade
Cold Install means Fresh Install,If yo want to do cold install than manually you need to copy all your configuration files & after installing you need to configure tham again.

Re: Rolling Upgrade
> Any experienced system administrator would not use upgrade-ux.
I think that's unfair SEP... It wouldn't be my starting position for a 11.11-11.23 upgrade, but it can and does work - and as long as you have an Ignite backup to fall back to is no more risky than a cold install.
I've even see it work well on 10.10-10.20, 10.20-11.00 and 11.00-11.11 upgrades. You just have to be careful and follow the instructions in the manual carefully:
http://docs.hp.com/en/5992-1978/5992-1978.pdf
Other things to look at prior to an update-ux run:
- Ensure there are no unconfigured filesets on the system... something like this should return nothing:
swlist -l fileset -a state | sed -e '/^#.*$/d' -e '/^$/d' | grep -v configured
- ensure that you at least review a run of "swverify \*" - in general you don't need to worry too much about the WARNING levels, but you shoulkd always try and resolve the ERROR levels.
- if you have non-HP kernel filesets (such as EMC PowerPath or IBM atdd tape drivers), you should consider removing it for the course of the upgrade...
- always run a preview of the update-ux process and resolve *all* reported issues before proceeding

Re: Rolling Upgrade
I will assign some points when I finish my setup.
I run Update-ux and I get some erros, with space openssl and ssh.
space -> not enought space in /opt
openssl ->
openssh -> a higher revision was already installed
I running now the recover tape to re-dimension the size of /opt, then i will try to uninstall ssh e openssl and at last run again update-ux.
After I try that I will summarize my conclusions.
Any advice ?
I think this is the correct approach.
