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 cannot share LUNs with any other HBAs.
HBA configuration
• Host 1 is a single path HBA host with NetWare.
• Host 2 is a dual HBA host with multipathing software.
See Figure 33.
Risks
• Single-path failure will result in a loss of connection with storage devices.
