This is the second post of my little project of building my own RAC on my Windows7-desktop (64-bits, 8GB RAM), using 3 VM’s (VM-workstation , 7.1.3 build-324285) : * 2 VM’s for two RAC-nodes, based on OEL 5.5, 11.2.0.2 for infra, and database. * 1 VM as my own SAN, based on Openfiler 2.3 (free), for ASM.

My current job doesn’t offer me at the moment the opportunity to play with RAC or other stuff, so I decided to build my own RAC on my Windows7-desktop (64-bits, 8GB RAM), using 3 VM’s (VM-workstation , 7.1.3 build-324285) : * 2 VM’s for two RAC-nodes, based on OEL 5.5, 11.2.0.2 for infra, and database. * 1 VM as my own SAN, based on Openfiler 2.3, for ASM.

I was building my own Oracle RAC 11g cluster (11.2.0.2) with Openfiler as my shared storage. Two VM's as my rac-cluster, one VM with Openfiler as my own SAN. Followed the instructions of the article of Jeffrey Hunter how to build a RAC on OEL and iSCSI, however this article is not based on VM. My Openfiler-VM was ready, given access to my both nodes on iSCSI-level, and now I want my rac1-node to discover the iSCSI-drives on my Openfiler.
