Replacing global disk device

Question

Hi,
Looking for suggestions, guidelines, HOWTOs, etc. for the following scenario.
SC 3.2, Sol 10 08/07
We have a 50GB global disk device on SANA in a two-node cluster. We need to replace this device with a LUN from SANB as part of our storage migration project. This device is also a quorum device, and it is the data directory for the Oracle application group in the cluster.
How do I stop the Oracle group but mount the disk for copying the data, and then how do I change the configuration to accept the new disk as the cluster and quorum device?
Thanks.

Tim,
thanks for the information. It's almost exactly what I need, but there's one more bit I need some guidance on. I realize this is kind of basic stuff, but it's been a while since the cluster was created and configured (along with the RG) and the administration has been pretty hands-off during that time period. How do I swap out the disk resource A for B? I was looking at the properties of the RG and the resource yesterday and it only seemed to be based on the mount point rather than the DID, but I would think that there is a setting/dependency configured for the actual DID somewhere in there.

And on the off chance that it isn't configured to the DID, but should be, how do I set that to make this proper? There is an entry for /u02 in vfstab on both nodes. Is that the correct way? Again, it has been a long time since I set this up. :)
