Resolution

Procedure:     

  1. Collect the ag --mapshow output to see where the f-ports are mapped to which N-port.
  2. Set the port back to factory default with the command <portcfgdefault (port no) >.
Example: portCfgDefault 8 
  1. Check the port status with the command switchshow if the port is out of persistentdisable state.
Example: After portcfgdefault command, the status changed to: In_Sync FC Disabled (No mapping for F-Port)
  1. Enable the port with the command: portenable (port no).
  2. Map the port back to the original N-port with command: ag –mapadd (n-port) (f-port).
Example: ag --mapadd 20 "8"
  1. Check if the port is mapped to the N-port with the command: ag --mapshow.
  2. Check the port status with the command: switchshow. Expect the port to be online.
Example: Online  FC  F-Port
