Each IPFC instance communicates through a specific Fibre Channel adapter port. To configure an IPFC instance, it is first necessary to identify the FC HBA port instance (fp driver instance).
You can determine the fibre channel adapter port instance based on any of the following:
WWN of a remote device or IPFC instance visible by the HBA port. For more information, see Determining HBA Port Instance Number from Physical Device Path.
WWN of the HBA port. For more information, see Determining HBA Port WWN from Remote WWN.
Controller number of the HBA port. For more information, see Determining Controller Number from HBA Port WWN.
Oracle Solaris physical device path of the HBA port. For more information, see Determining Physical Device Path from Controller Number.
