Quorum configurations depend on the number of nodes in the
cluster: Two-Node Clusters: Two quorum votes are required for a
two-node cluster to form. These two votes can come from the two
cluster nodes, or from just one node and a quorum device.
Nevertheless, a quorum device must be configured in a two-node
cluster to ensure that a single node can continue if the other
node fails. More Than Two-Node Clusters: You should specify a
quorum device between every pair of nodes that shares access to
a disk storage enclosure. For example, suppose you have a three-
node cluster similar to the one shown in the following figure
Quorum Device Configuration Examples. In this figure, nodeA and
nodeB share access to the same disk enclosure and nodeB and
nodeC share access to another disk enclosure. There would be a
total of five quorum votes, three from the nodes and two from
the quorum devices shared between the nodes. A cluster needs a
majority of the quorum votes to form. Specifying a quorum device
between every pair of no
