AIX

Hi.

We have a two node HA cluster.
We got a request to change one of the VG name?
Is there an option to do this online ? If it requires downtime can someone please explain me the steps for doing it ?
Let me know if you need any outputs from the servers

you have to export and import the vg with the new name on both nodes, don't forget to use the same major number as before
maybe it's possible in aix 7 with the new "rendev" command haven't tried so far

but you need to do this with the resource groups shut down,
better if possible with the cluster shut down


then go to:

Code:

smitty config_resource_group_change.select

and update the resource group with the new vg name

sync the cluster afterwards


just for info: the vg name has no impact on anything, but changing it may lead to troubles
don't forget to check /etc/filesystems after importing
