Risks
• Single path failure will result in loss of connection with the storage system.
• Single path failure may cause the server to reboot.
• Controller shutdown puts controller in a failed state that results in loss of data accessibility
and loss of host data that has not been written to storage.
NOTE: For additional risks, see “Windows Servers” (page 93).
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 on single path HBA servers.

Requirements
• Switch zoning or controller level SSP 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.
