HBA configuration
• Host 1 is a single path HBA.
• Host 2 is a dual HBA host with multi-pathing software.
See Figure 37 (page 123).
Risks
• Single path failure may result in data loss or disk corruption.
NOTE: For additional risks, see “Linux failure scenarios” (page 129).
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 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.
• All nodes with direct connection to a disk must have the same access paths available to them.
