You create a host cluster when two or more hosts require I/O access to the same volumes.
Keep these guidelines in mind when you create a host cluster:
If any of the host connections on the controllers in your storage array do not support DA, the associated hosts cannot access data on DA-enabled volumes.
DA is not supported by iSCSI over TCP/IP, or by the SRP over InfiniBand.
The new host cluster appears in the table with the assigned hosts in the rows beneath.
