You must follow the SAN Volume Controller configuration rules for fibre-channel host bus adapters (HBAs).
The SAN Volume Controller must be configured to export virtual disks (VDisks) only to host fibre-channel ports that are on the list of supported HBAs. See the Support for SAN Volume Controller (2145) Web site for specific firmware levels and the latest supported hardware:
www.ibm.com/storage/support/2145
Operation with other HBAs is not supported.
The SAN Volume Controller does not specify the number of host fibre-channel ports or HBAs that a host or a partition of a host can have. The number of host fibre-channel ports or HBAs are specified by the host multipathing device driver. The SAN Volume Controller supports this number; however it is subject to the configuration rules for the SAN Volume Controller. To obtain optimal performance and to prevent overloading, the workload to each SAN Volume Controller port must be equal. You can achieve an even workload by zoning approximately the same number of host fibre-channel ports to each SAN Volume Controller fibre-channel port.
The SAN Volume Controller supports configurations that use N-port virtualization in the host bus adapter or SAN switch.
