The PRKey is a permanently reserved value in the form of 00000101, where the first six digits 000001 stand for a cluster, and the following two digits 01 stand for a node. Different PRKeys must be set for different nodes. For example, if there are two nodes in a cluster, the PRKeys of the nodes can be set to 00000101 and 00000111 respectively.
In clustered environments (such as MSCS and VCS), users must enable the cluster function of multipathing software and set different PRKeys for different nodes to prevent resources to be offline.
