Requirements
• Proper switch zoning must be used to ensure each single path HBA has an exclusive path to
its LUNs.
• Single path HBA server can be in the same fabric as servers with multiple HBAs.
• 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
controller. In the case of snapclones, after the cloning process has completed and the clone
becomes an ordinary virtual disk, you may present that virtual disk as you would any other
ordinary virtual disk.
