Review the event browser to determine if excessive port errors are responsible for
disabling the port. Look for a message that mentions one of the monitored error
types indicating that the port has been disabled, then do the following:
1. Examine the alarm configuration for the associated error using the Show
Config Threshold command. Refer to the Show Config Threshold command
in the SANbox 5802V Fibre Channel Switch Command Line Interface Guide.
Are the thresholds and sample window correct?
Yes - Continue
No - Correct the alarm configuration. If the condition remains, continue.
2. Reset the port, then perform an external port loopback test to validate the
port and the SFP. Refer to the SANbox 5802V Fibre Channel Switch
Command Line Interface Guide or the SANbox 5802V QuickTools Switch
Management User Guide for information about testing ports. Does the port
pass the test?
Yes - Continue
No - Replace the SFP and repeat the test. If the port does not pass the
test, contact your authorized maintenance provider. Otherwise
continue.
3. Replace the Fibre Channel port cable. Is the problem corrected?
Yes - Complete.
No - Continue.
4. Inspect the device to which the affected port is connected and confirm that
the device and its HBA are working properly. Make repairs and corrections
as needed. If the condition remains, contact your authorized maintenance
provider.
