Risks Limitations Host 2 is a dual HBA host with multipathing software. See Figure 35. Single path failure may result in data loss or disk corruption. NOTE: For additional risks, see “Linux” on page 77. HP Continuous Access EVA 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. 2 Figure 35 Linux (Itanium) configuration 1. Network interconnection 2. Single HBA server (Host 1) 3. Dual HBA server (Host 2) 4.

IBM AIX configuration Requirements HBA configuration Risks Limitations 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. Single path HBA server cannot share LUNs with any other HBAs. In the use of snapshots and snapclones, the source virtual disk and all associated snapshots and snapclones must be presented to the single path hosts that are zoned with the same controller. In the case of snapclones, after the cloning process has completed and the clone becomes an ordinary virtual disk, you may present that virtual disk as you would any other ordinary virtual disk. HBA must be properly configured to work in a single HBA server configuration. The single path adapter driver from the AIX MPIO EVA Kit should be installed: PC1000.image. Host 1 is a single path HBA host. Host 2 is a dual HBA host with multipathing software. See Figure 36. 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” on page 77. HP Continuous Access EVA is not supported with single path configurations. Single path HBA server is not part of a cluster. Booting from the SAN is not supported.
