Before you start configuring a port with multipathing feature, consider the following factors:
FC global and per-port multipath setting is specified in the /kernel/drv/fp.conf file.
Per-port multipath settings have priority over the global settings. When global multipathing is enabled and if a specific port is disabled for multipathing, that port will not be available in the multipathing configuration. Conversely, when global multipathing is disabled and if a specific port enabled for multipathing, that port is listed in the appropriate driver.conf file.
If a device has more than one path to the host, all paths to the device must either be enabled or disabled for I/O multipathing.
Configuring multipathing on a port enables the Oracle Solaris I/O multipathing feature to co-exist with other third-party multipathing solutions. However, devices and paths must not be shared between the Oracle Solaris I/O multipathing software and other third-party multipathing solutions.
