Voting disk:
As far as voting disks are concerned, a node must be able to access strictly more than half of the voting disks at any time. So if you want to be able to tolerate a failure of n
voting disks, you must have at least 2n+1 configured. (n=1 means 3 voting disks). Oracle Clusterware supports a maximum of 32 voting disks.It is recommended to use an odd number as 4 disks will not be any more highly available than 3 disks, 1/2 of 3 is 1.5...rounded to 2, 1/2 of 4 is 2, once we lose 2 disks, our
cluster will fail with both 4 voting disks or 3 voting disks.
