Basic Qs Hi 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! ...

Basic Qs 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. **************** CAUTION - Disclaimer ***************** This e-mail contains PRIVILEGED AND CONFIDENTIAL INFORMATION intended solely for the use of the addressee(s).
