32xx: Direct-attached single-controller configurations

You can connect hosts directly to FC target ports on a single controller. Each host can connect to one port, or to two ports for redundancy. The number of hosts is limited by the number of available target ports.

If you use multiple paths to a LUN, multipathing software is required on the host.

Direct-attached configurations typically need the FC ports set to auto mode. Be sure to follow the recommendation of your host operating system provider for FC port settings. You can use the fcp config mediatype command to set the target ports; see the fcp man page for more information about that command.

Note: The FC target port numbers in the following figure are examples. The actual port numbers might vary depending on whether you are using onboard ports or FC target expansion adapters. If you are using FC target expansion adapters, the target port numbers also depend on the expansion slots into which your target expansion adapters are installed.
