With this setup we are facing the issue that if we loose a complete SAN, the IO’s to the ASM diskgroups will be blocked for approx 3 till 4 minutes. Oracle does not like this. After 70 seconds after a freeze, rdbms is starting to reboot (expected behaviour).
Red Hat 6 has been there a while, so what about certification with Oracle? Nothing on the Oracle support site, no press releases (maybe I missed one..). But Red Hat finally gave the answer in her Red Hat news - blog
Using rdbms 11.2 as the repository for our Grid Control environmont, noticed a lot of the same errors in the alert file of the repository or/and the target database:
NI cryptographic checksum mismatch error: 12599.

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, 18.104.22.168 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, 22.214.171.124 for infra, and database. * 1 VM as my own SAN, based on Openfiler 2.3, for ASM.
While installing a grid - infrastructure on my own RAC-cluster (VMware), using ASM with Openfiler as by own SAN, the prerequisite-check fails at step 15 with : PRVF-5150 : Path ORCL:VOL1 is not a valid path on all nodes
While building my own RAC on two VM's, using a third VM with Openfiler on it as my SAN, I had to dowload, install, configure and load ASMLIB. Loading didn't seem to go smoothly at my own project. First I analyzed what I did, steps I took
I was building my own Oracle RAC 11g cluster (126.96.36.199) 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.
