5. Display the active zone set on each switch using the Zoning Active
command, or click the Active Zoneset tab in QuickTools. 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, then reset the port. If the
condition remains, contact your authorized maintenance provider.
Excessive Port Errors
The switch can monitor a set of port errors and generate alarms based on
user-defined sample windows and thresholds. These port errors include the
following:
Cyclic Redundancy Check (CRC) errors
Decode errors
ISL connection count
Device login errors
Device logout errors
Loss-of-signal errors
Port threshold alarm monitoring is disabled by default. Refer to the SANbox
5802V Fibre Channel Switch Command Line Interface Guide for information about
managing port threshold alarms.
If the count for any of these errors exceeds the rising trigger for three consecutive
sample windows, the switch generates an alarm and disables the affected port,
changing its operational state to down. Port errors can be caused by the following:
Triggers are too low or the sample window is too small
Faulty Fibre Channel port cable
Faulty SFP
Faulty port
Faulty device or HBA
NOTE:
E_Port isolation can be caused by merging two fabrics whose
active zone sets have two zones with the same name, but
different membership.
