Hi
I was doing some cluster destructive tests on RAC 11gR2 a few days ago.
One of tests was kill ASM and see how does that affects Clusterware
operation since OCR and Voting Disks are located in ASM (OCRDATA Disk
Group). After killing ASM nothing happened as it was quicky started up
again. So far so good. The next test was same test but changing the ASM
Disks ownership so when ASM is restarted OCR Disk Group cannot be accessed.
Surprisingly ASM Was started up, Database Disk Group was mounted OCR disk
Group obviously did not get mounted but then the Cluster was working without
any problems.
So how is this happening? Doesnt Clusterware need to write and read to
Voting Disk every second? I was expecting a Clusterware failure in the node
but everything worked just as everything were ok.
Thanks!
