Block and Unblock Ports
This section describes procedures to block or unblock the switch ports. When a port is
blocked, the port is automatically set offline. When a port is unblocked, the port is
automatically set online.
NOTE: When a port is blocked, the operation of an attached Fibre Channel device is disrupted.
Do not block a port unless directed to do so by a procedural step or the next level of support.
