Solving System Faults; Viewing The System Fault Solving Method; Saving The Current Configuration Of The Router - H3C SR6604 Installation Manual

Solving system faults

Solving system faults
When the system detects faults (such as system instruction faults, invalid addresses, data overflow, null
pointers, and division by zero operations) during the operation of the active MPU or standby MPU, you
can solve the problem in one of the following methods:
reboot: Rebooting the failed MPU so that the MPU restores to normal operational status.
•
maintain: Maintaining the current status of the failed MPU so that the system does not take any
•
restoration measures. Some software faults are hard to reproduce, and the printed information will
be lost after the router reboots. In this case, you can maintain the current status of the router,
facilitating fault location.
Follow these steps to solve system faults:
To do...
Enter system view
Specify the system fault solving
method for the active MPU and
standby MPU
NOTE:
On a router with two MPUs, rebooting the active MPU triggers an active and standby switchover, and the
•
former standby MPU takes over.
On a router with only one MPU, rebooting the active MPU reboots the router.
•
• If the FIP or SAP/OAP module encounters software faults, the solving method is always reboot, which
reboots the failed module.
When system faults occur, the system fault solving method applies to only the failed module, and
•
rebooting the module does not interrupt the other modules.

Viewing the system fault solving method

Use the display system-failure command to display the system fault solving method.
<Sysname> display system-failure
System failure handling method: reboot

Saving the current configuration of the router

You can save the current configuration of the router in one of the following methods:
Fast saving: Executing the save command without the safely keyword. This mode saves the file more
•
quickly but is likely to lose the existing configuration file if the router reboots or the power fails
during the process. The fast saving mode is suitable for environments where the power supply is
stable.
Safe saving: Executing the save command with the safely keyword. The mode saves the file more
•
slowly but can retain the configuration file in the router even if the router reboots or the power fails
Use the command...
system-view
system-failure { maintain |
reboot }

Remarks
—
Optional
reboot by default for the active
MPU and standby MPU.
