The primary objective of the shared storage connectivity in a cluster is to provide solid and stable connectivity between cluster nodes and the storage system. Before installing OES Cluster Services and setting up a cluster, ensure that the storage configuration is established and verified.
Use the guidelines in this section to design the storage connectivity for a cluster:
Use host-based multipath I/O management. See the following resources:
Connect each node via two fabrics to the storage area network (SAN).
Use redundant SAN connections to provide fault-tolerant connectivity between the cluster nodes and the shared storage devices.
Use LUN masking to exclusively assign each LUN to one or more host connections. See Section 4.9, SAN Rules for LUN Masking.
