Requirements

Switch zoning or controller level SSP must be used to ensure each HBA has exclusive access
to its LUNs.
All nodes with direct connection to a disk must have the same access paths available to them.
Single HBA server can be in the same fabric as servers with multiple HBAs.
In the use of snapshots and snapclones, the source virtual disk and all associated snapshots
and snapclones must be presented to the single host that are zoned with the same controller.
