becomes an ordinary virtual disk, you may present that virtual disk as you would any other
ordinary virtual disk.
HBA configuration
• Host 1 is a single path HBA host.
• Host 2 is a dual HBA host with multipathing software.
See Figure 37 (page 90).
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 “IBM AIX” (page 95).
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.
