Applies to

  • Brocade switches
  • FC Protocol

Answer

  • As long as all connected ports are correctly zoned, the failover will occur seamlessly during a path removal. 

WARNING

Ensure that zoning is configured on each switch and MPIO is properly set up on the host end before removing the standby ports.

Additional Information

  • If a host cluster is connected to two switches, with each host having two connections to each switch (one optimized, one unoptimized), removing connections in a multipathing storage setup will cause traffic to switch to the standby connection if an active connection is removed.
  • Removing a port from each node won’t cause downtime if redundant paths are present and should prevent downtime. 
  • However, latency issues might occur if the optimized path is removed.
