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?
