Risks
• Single path failure may result in loss of data accessibility and loss of host data that has not
been written to storage.
• Controller shutdown results in loss of data accessibility and loss of host data that has not been
written to storage.
NOTE: For additional risks, see “Oracle Solaris failure scenarios” (page 132).
Limitations
• HP P6000 Continuous Access is not supported with single path configurations.
• Single path HBA server is not part of a cluster.
• Booting from the SAN is not supported.

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.
