It sounds like you want to build a parallel Sun Cluster while VCS is active. WOW! My initial reaction would be no. But.... Why not? Since you're going to be using on a completely different storage frame. You would be looking at a second set of resources, such as VIP's. You already have the SAN. Even if you're able to get fairly far into the build, you won't be able to test it very well. Honestly, I don't know the answer you're looking for. If it were me, I would start by disabling and shutting down VCS. If they can't give you a maintenance window to do the work, do they understand the risk of having this box sitting there like a dead fish? Be sure to break the mirroring so you have a quick way to get back to a running and healthy cluster.
"I" still would not go this route. You will most likely create a lot more headaches than what you may be prepared for.
Is it possible for you to take one of the nodes out of the VCS cluster and build that one as a Sun Cluster? Easily done if you have a active/passive cluster. Then you would have two one node clusters. Your VCS cluster can keep your production apps up and running during your build of the Sun Cluster node. Once finished, you can add the VCS node to your Sun Cluster node.

mkqdisk
mkqdisk(8) Quorum Disk Management mkqdisk(8)
NAME
mkqdisk - Cluster Quorum Disk Utility
WARNING
Use of this command can cause the cluster to malfunction.
SYNOPSIS
mkqdisk [-?|-h] | [-L] | [-f label] [-c device -l label] [-d [-d ...]]
DESCRIPTION
The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.
OPTIONS
-c device -l label
Initialize a new cluster quorum disk. This will destroy all data on the given device. If a cluster is currently using that device
as a quorum disk, the entire cluster will malfunction. Do not run this on an active cluster when qdiskd is running. Only one
device on the SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
RAID array is used for quorum disk redundancy). The label can be any textual string up to 127 characters - and is therefore enough
space to hold a UUID created with uuidgen(1).
-f label
Find the cluster quorum disk with the given label and display information about it.
-L Display information on all accessible cluster quorum disks.
-d Increase debugging level. Specify multiple times for more information. Currently, specifying more than twice has no effect.
