Re: non-concurrent VG can be varyon on two nodes

I don't understand the "as shared VG seperately using cluster LVM"

Do you mean that you used the C-SPOC utilities to create the VG?

There isn't much information in the post, but here is what comes
immediately to mind:

1) The hdisk2 and hdisk3 disks are not really the same between
the nodes. Check the pvid to make sure that they are.

If you used C-SPOC, then this shouldn't be a problem.

2) There is an option set on your storage for no-reserve policy.

This is possible on several different disk types, including IBM and
OEM disk vendors.

Use lsattr -El <diskname>

Hope this helps to give you a start.
Good luck resolving your problem
