Re: In Oracle Extended RAC can inaccessibility of quorum failgroup cause node eviction

If you have three voting disks and 2 is in the same array if the firmware upgrade takes more than 200 seconds then you will have eviction so place the third quorum in a NFS Server and you won't have problems

Thank you
