• Single path failure will result in loss of connection with the storage system.

• Single path HBA server cannot share LUNs with any other HBAs.

• In the use of snapshots and snapclones, the source virtual disk and all associated snapshots

and snapclones must be presented to the single path hosts that are zoned with the same
