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 the HBA Port Instance Number From a Physical Device Path.
WWN of the HBA port. For more information, see Determining the HBA Port WWN From a Remote WWN.
Controller number of the HBA port. For more information, see Determining the Controller Number from an HBA Port WWN.
Oracle Solaris physical device path of the HBA port. For more information, see Determining the Physical Device Path From the Controller Number.
