The target virtual port is:'NetApp FC Target Port (8324) Xxxx:xxxx_1x_0f'. The target virtual port is:'NetApp FC Target Port (8324) XGxxx3:xxx_1x_0f'. Check that the AEN 0X8048 messages are no longer present in the event logs. Verify that the "received optical power" for all the FC adapters is within expected values.
