Cisco MDS 9000 Series Command Reference discards pending changes, and releases the lock on a fabric. Any other combination of fabric modules or Cisco MDS 9506 or Cisco MDS 9509 will not let the ports come up in 10 Gbps. Port security features prevent unauthorized access to a switch port in the Cisco MDS 9000 Family: • Login requests from unauthorized Fibre Channel devices (Nx ports) and switches (xE ports) are rejected. First steps I would Need some help figuring out what is causing the interface discards and how to solve this behaviour.

Every time i run a backup to tape, the FC ports on the tape drive go offline, the FC ports on the switch go offline as well. PortChannel refers to the aggregation of multiple physical Fibre Channel ports into one logical port to provide high-aggregated bandwidth, load balancing, and link redundancy For the Cisco MDS 9700 switches, MDS 9500 switches, and MDS 9250i switch, ensure that you create the Ethernet port channel interface before you create the virtual Fibre Channel port channel interface. However, we support ID numbers ranging from 257 to 4096 on the MDS Ethernet port channel. See the "Enabling Distribution" section.
