Recent Synchronization Attempts Log
This table describes the possible result and causes of synchronization states.
If the Synchronization Attempts log indicates that the Synchronization attempt
was aborted, use this table to further interpret the cause.
Table 18 - Recent Synchronization Attempts Log - Result Interpretations
Result Result Interpretation
Undefined The result of the synchronization is unknown.
No attempt since last powerup Synchronization has not been attempted since power was applied to
the module.
Success Full synchronization was successfully completed.
Abort The synchronization attempt failed. See the table Recent
Synchronization Attempts Log - Result Interpretations for further
information.
Table 19 - Synchronization Interpretation
Cause Cause Interpretation
Undefined The cause of synchronization failure is unknown.
Module Pair Incompatible Synchronization aborted because one or more module pairs are incompatible.
Module Configuration Error Synchronization aborted because one of the modules is improperly configured.
Edit Session In Progress Synchronization aborted because an edit or session is in progress.
Crossloading Failure An undetermined failure occurred during synchronization between redundancy modules.
Comm Disconnected The cable between the redundancy modules was disconnected.
Module Insertion Synchronization aborted because a module was inserted into a chassis.
Module Removal Synchronization aborted because a module was removed from a chassis.
Secondary Module Failed Synchronization aborted because of a failure in the secondary module.
Incorrect Chassis State Synchronization aborted due to an incorrect chassis state.
Comm Does Not Exist Synchronization could not be performed because the communication link between redundancy modules does not exist.
Nonredundant Compliant Module Exists Synchronization could not be performed because one or more nonredundancy modules are present in one of the chassis.
Sec Failed Module Exists A module in the secondary chassis has asserted the SYS_FAIL line, indicating that it has faulted or failed.
Local Major Unrecoverable Fault Synchronization was aborted because of a local major unrecoverable fault.
Partner Has Major Fault Synchronization was aborted because the partner module has a major fault.
Sec SYS_FAIL_L Subsystem Failed The test of the SYS_FAIL line in the secondary chassis failed.
Sec RM Device Status = Comm Error Synchronization was aborted because the secondary redundancy module’s status indicates a communication error.
Sec RM Device Status = Major Recoverable
Fault
Synchronization was aborted because the secondary redundancy module’s status indicates a major recoverable fault.
Sec RM Device Status = Major Unrecoverable
Fault
Synchronization was aborted because the secondary redundancy module’s status indicates a major unrecoverable fault.
Incorrect Device State Synchronization was aborted because the device is in the wrong state.
Primary Module Failed Synchronization was aborted because of a failure in the primary module.
Primary Failed Module Exists A module in the primary chassis has asserted the SYS_FAIL line, indicating that it has faulted or failed.
Auto-Sync Option Synchronization was aborted because the Auto-Synchronization parameter of one of the redundancy modules was changed during
synchronization.
