Sun cluster and Veritas cluster question.

Yesterday my customer told me to expect a vcs upgrade to happen in the future. He also plans to stop using HDS and move to EMC.

Am thinking how to migrate to sun cluster setup instead.

My plan as follows leave the existing vcs intact as a fallback plan.

Then install and build suncluster on existing production servers which are connected to both HDS and EMC storage. configure the suncluster to use emc disk whilst vcs is still attached to HDS storage.

Once suncluster+EMC and all filesystems are created and working properly get a downtime copy data over from old vcs setup. then test with the application in the sun cluster.

My questions as follows:
1) Does anybody forsee any problems if vcs and suncluster cluster setups co-exist side by side?

2) Anybody done any similar cluster migrations in the past?

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. SEE ALSO
