3.Display the active zone set on each switch using the Zoning Active command or the Active Zoneset tab of the SANbox Manager topology display. Compare the zone membership between the two active zone sets. Are they the same?

■Yes - Contact your authorized maintenance provider.

■No - Deactivate one of the active zone sets or edit the conflicting zones so that their membership is the same. Reset the port. If the condition remains, contact your authorized maintenance provider.

Note: This can be caused by merging two fabrics whose active zone sets have two zones with the same name, but different membership.

5.1.2.2

Excessive Port Errors

The switch monitors a set of port errors and generates alarms based on user- defined sample intervals and thresholds. Refer to the SANbox2-64 Switch Management User’s Guide for information about managing alarms. These port errors include the following:

■CRC errors

■Decode errors

■ISL connection count

■Login errors

■Logout errors

■Loss-of-signal errors

If the count for any of these errors exceeds the rising threshold for three consecutive sample intervals, the switch generates an alarm and disables the affected port, changing its operational state to “down”. Port errors can be caused by the following:

■Thresholds are too low or the sample interval is too small

■Faulty Fibre Channel port cable

■Faulty SFP

■Faulty port

■Fault device or HBA

Review the alarm log 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:
