IMPORTANT:
Do not use the LUN until you configure MPIO.

Clustering server connections
You can cluster servers to assign multiple server connections to multiple volumes in a single
operation. Cluster existing servers or create new servers to add to the server cluster from the New
Server Cluster window. If you cluster servers that already have volumes assigned to them, all the
servers in the cluster gain access to all the volumes, and inherit the access permissions of the
original pair.
All clustered servers must have the same load balancing and volume access permission settings.
You can verify and update these settings when you create the server cluster. For information about
volume access permissions, see
“Server connection permission levels” (page 209)
. For more
information about iSCSI load balancing, see
“iSCSI load balancing” (page 241)
