Port Name and Node Name
Used to identify the device. The device may have multiple Fibre Channel ports with each having a unique Port Name. The
drive is a dual-ported device.
The Port and Node Names in the PLOGI identify the initiator. The drive saves the Port Name of the initiator with the login
parameters. If a change of the Port Name/AL_PA address association is detected during a Port Discovery (PDISC), an
implicit logout occurs (any queued commands for the previous Port Name/AL_PA are discarded, the previous login is
cleared) and a LS_RJT is returned to the initiator.
The Port and Node Names in the PLOGI ACC identify the drive. The drive uses a format for the Port and Node Names
defined as the IEEE extended address. The format is in Table 23.
