Applies to:

Cisco MDS 9124 24P Multilayer Fabric Switch - Version All Versions to All Versions [Release All Releases]
Cisco SAN Switch Hardware - Version Not Applicable to Not Applicable [Release N/A]
Information in this document applies to any platform.

Goal

The intent of this document is to provide the reader with the available commands to disable and enable a FC port on FC Cisco switch (reset the port or offline/online the port), so the device connected to that port can login into the fabric again.

This is a basic troubleshooting procedure when a device connected to the SAN is not available on the FC switch.

On this example on a CISCO MDS 9124 FC switch, initially, 'show fcs database' no longer see PWWN of Tape library device . fc1/8 port now shows Type "Unknown" and None for PWWN.
