I’ve a question related the portCfgAutoDisable command.
Man page & Command reference Guide report this command set a flag to disable automatically under any conditions that would cause the port to reinitialize “loss of sync, loss of signal, OLS, or NOS”.
> The question is, from how many events listed above the port is set disable. Is there any specific threshold set on the FOS and documented ?
Thanks for feedback.
“The port auto disable feature minimizes traffic disruption introduced in some instances when automatic port recovery is performed.
When the auto disable flag is set, the specified ports disable automatically under any conditions that would cause the port to reinitialize.
Such conditions include loss of sync, loss of signal, OLS, or NOS.
Note that a link reset does not cause a port auto disable.
When a port is in FICON Management Server (FMS) mode, an auto disabled port remains persistently disabled across HA failover.
In all cases, the automatically disabled port may be brought back into service using the portEnable command.”
