Resize hdisks on active cluster
permalink
Hi AIXers

We need to grow hdisks in a two disk VG that resides on two DS4300s.
The LV on the hdisks is mirrored an the disks are varied on in enhanced concurrent mode on two nodes (active and passive)

The chvg -g command has been successfully executed before
so I know that works and is a very helpful feature.

The man pages seems to give a warning about enhanced concurrent mode?

Is this a no-no on a live cluster or can I go ahead with no worries that the cluster will go down.

Thanks,
Jan

hi..

You cant use chvg -g option for enhance concurrent vg. instead of this u can add pv to vg in running cluster.
