how to active VG in shared mode!

[leyearn]

I created a VG vg_ops on diskArray
and created some LVs which will be used by oracle as raw devices
and MC is OPS version
I havn't changed the MC's configuration file
I want to test the VG
now the VG can be actived on two nodes
by
#vgchange -a y
separately
how can I active the VG in shared mode?

[root@yjjf2]# vgchange -S y -c y vg_ops
Performed Configuration change.
Volume group "vg_ops" has been successfully changed.
[root@yjjf2]# echo $?
0
[root@yjjf2]# vgdisplay vg_ops
vgdisplay: Volume group not activated.
vgdisplay: Cannot display volume group "vg_ops".

why after I #vgchange -S y -c y vg_ops
I can't vgdisplay It?

Hi,

Use #vgchange -a e
To activate VG in shared mode.

Also don't forget to add this is the cluster config file.

You have only marked the VG as shareable and in a cluster, you have not activated it, use:

vgchange -a s
