4. If you are in buffer-limited mode on the LD port, increase the estimated distance.
These changes are implemented only after disabling (portDisable) and enabling (portEnable) the
buffer-limited port (or buffer-limited switch).
Reconfiguring a port to LD from another mode can result in the port being disabled for lack of
buffers—this does not apply to the SAN Switch 4/32 and 4/256 SAN Director (using FC4-16 and
FC4-32 port blades). If this happens:
• In Fabric OS 4.2.x, reconfigure the disabled LD port back to the original mode.
• In Fabric OS 4.4.0 and later, specify a slightly shorter distance for the desired_distance
parameter in the portCfgLongDistance command.
