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 multiple HBA host with multi-pathing software. See Figure 32 (page 116). 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 Server failure scenarios" (page 128). 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.
