SUMMARY: Cannot register VxVM 4.1 disk group with Sun Cluster 3.1

Well, as in most things, the trick to getting the answer is knowing
the right question to ask.

I assumed that since the volume created and it wouldn't register the
disk groups that it was a Cluster issue. As it turns out, it's more of
an interfacing problem between Cluster and VxVM similar to the ones
with EMC storage.

I installed the maintenance pack 2 for VxVM 4.1 plus Cluster 3.1 VxVM
patchand I was able to register the disk group. The only remaining
trick was for any disk group with layered volumes; the disk group had
to be registered before volumes were layered and then synced after the
layered volume creation.

The two patches that I installed were:

117080-07
124358-05

Thanks to Simon for responding on the issue.
