Feb 17 04:42:54 fcns: vsan 99: Trying to send RSCN; affected port 780200
Feb 17 04:42:54 fcns: vsan 99: rscn timer started for port 780200

Feb 17 04:42:54 fcns: vsan 99: sending accept response to 780200

Feb 17 04:42:55 fcns: vsan 99: Registered fc4-types for port-id 780200
Feb 17 04:42:55 fcns: vsan 99: Registered fc4-features for fc4_type 8 for port-id 780200
/* FC4 Type, type 8 FCP has been registered */
Additional lines like these will be listed if additional nameserver objects are registered
Step 8 From the CLI exec mode, enable FC name server (FCNS) debugging by entering the following
command:
debug fcns events register vsan x
If you are managing the switch over a telnet connection, enable terminal monitoring by entering the
terminal monitor command from the CLI exec mode.
The system output looks like this:
switch# show fcns database detail v 99

Other attribute objects of the Nx port are registered one per register operation after the FLOGI process
is complete. The Nx port performs PLOGI to the well-known WWN of the Name Server, 0xFFFFFC.
The FC_CT Common Transport protocol uses Request and Accept messages to conduct transactions. To
verify that additional attributes are correctly registered and recorded in the database, you can use the
SAN-OS debug facility.
