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 or the SANbox Manager application. Refer to the ”Show Config Command” on page B-78. Refer to Table B-7for a list of the alarm configuration defaults. Are the thresholds and sample interval 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 ”Test Command” on page B-89or the SANbox2-64 Switch Management User’s 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.
