Core issue
This message indicates that a fabric channel error has been detected. [chars] is the type of channel error, the first [dec] is the channel number, and the second [dec] is the module number.
Resolution
The system attempts to recover by re-synchronizing or resetting the module. If the system does not recover the module, replace the module.
The synchronization errors can be caused by a hardware issue or a badly seated card. Issue the show fabric channel switchmode command to check whether the SYNC status is OK. If it is status is OK you can try re-seating the module with testing set to Complete only for testing. Confirm that the testing is error free and that there are no errors in the log.
Perform these steps:
- Issue the set test diaglevel {complete} command.
- Reseat the module.
- Issue the show test command, and check for any errors recorded.
- Issue the show fabric channel counters command for any errors.
- If found are errors, monitor to see if they increment.
- Issue the show log command, and check for errors.
- Issue the set test diaglevel command, and set it back to Minimal.
- Verify that everything is error free.
