Volume Group added to Cluster

[okcunix]

I have a 2 node cluster. I added a new Volume Group/lvol to a node, and built all the entries on the second node. Updated the package files, and tested VG activation, works fine.
My question is, I can't remember if I need to update the cmclconfig.ascii file and run the check/apply routine? And can the cluster be active to do this? (MCSG 11.14)
It's been a while since I added a VG, can anyone help?

Hi,

The only entry for the VG in the ASCII file is for the cluster aware VGs. You can live without it if you like, but it makes things a little better since MC/SG knows which VGs should be cluster aware. You can add a volume group with the cluster running. Take a look at this link:

I assume that this is not a lock vg but otherwise the answer is yes you can and should.

1) cmgetconf -c mycluster > myconf.ascii

2) edit the file myconf.ascii and add your VG

3) Run cmcheckconf against the updated file

4) Run cmapplyconf

Man cmgetconf, cmcheckconf, cmapplyconf for details.

YEs you should update the cmclconfig.ascii file .
Yes you can do cmcheckconf and cmapplyconf while the cluster is active .

You don't have to - but it is highy recommended. As long it is not for a cluster lock - you can add it on the fly.
