Hi,
We are thinking upgrade our 3-nodes cluster openvms 8.2-1 itanium to
openvms 8.3. Right now every node boots off the the same system disk
which is on eva3000.
The upgrade approach we are trying to do
1. clone a system disk say disk B
Just one point here: I'd recommend an image backup to your
new (system) disk since that will defragment the volume in
the process. In addition, if you have the opportunity,
you could do a second image backup/restore of the *upgraded*
disk prior to moving the other nodes to it. (That might
be the fanatic in me speaking...season to taste. :-)
2. let node A,B boot from the original system disk
3. let node C boot from disk B ( change logicals for some common files
ie uaf , so node C use the same file as node A, B does)
4. upgrade node C
5. testing on node C
6. if everything is fine, let node A, B boot from disk B
7. after a couple of months, if everything is ok remove the original
system from cluster.
8. done
Wondering if anything I've overlooked ? Any suggestions? comments?
I'd echo Kerry's idea to use a separate disk for various
cluster-common files. That would be a pre-upgrade activity.
It will help keep the cluster consistent while the two different
system disks are both in use, and it does simply upgrades.
