Thanks LSC, Kevin, Folks for the advice & support.

Any sample Solaris 10 Commands / Pointers for Presenting the common LUN to both DB Server Node Machines?

STORAGE BOX is Sun StoreEdge 6920 model which is connected VIA a 2 GBPS Qlogic SAN 16 Port SANSwitch to Both the DB Server Nodes

Configuration:-
Solaris 10
Oracle 10gR2

Aim is to setup a 2 Node ASM RAC using External Redundancy. Cheers

As long as they are raw devices and you have presented LUNs to both servers the can be seen from both nodes.

Nothing to do with Sun Cluster Setup, nothing to do with fancy vg* commands and your third option is totally out of topic!

...

Thanks

Folks

How are the Oracle Cluster Registry (OCR) & Voting Disk (VD) device files to be Made Concurrently VISIBLE / Shareable to BOTH Database (Solaris 10) Nodes? Five RAW devices (2 OCR & 3 VD) of 200MB each were created only on the Node 1(Master node).

...not to be mean, but did you see any of this stuff you've done in any documentation anywhere? The answer is simply that you need shared disks. That can be dual-ported SCSI DAS, Fibre LUNS, iSCSI LUNS or NAS (NFS) files.
