Displaying operational statistics for the device

When you perform routine maintenance or the system fails, you might need to display the operational information of each feature module to locate failures. Typically, you need to run the display commands individually. However, you can use the display diagnostic-information command in any view to display or save the operational statistics of multiple feature modules of the device. This command displays the output of the display clock, display version, display device, and display current-configuration commands.

·           Save the operational statistics for each feature module of the device:

<H3C>­ display diagnostic-information                                            

Save or display diagnostic information (Y=save, N=display)? [Y/N]:y            

Please input the file name(*.diag)[cfa0:/default.diag]:                        

Diagnostic information is outputting to cfa0:/default.diag.                    

Please wait...                                                                 

Save successfully.                            

Execute the more default.diag command in user view, and then press the Page Up and Page Down keys to view the contents of the file default.diag.

·           Display the operational statistics for each feature module of the device. (Details not shown.)

Configuring the exception handling method

Configuration procedure

You can configure the device to handle system exceptions (such as system instruction faults, invalid addresses, data overflow, null pointers, and division by zero operations) by using one of the following methods:

·           Reboot—The device automatically reboots to recover from the error condition.

·           Maintain—The device stays in the error condition so you can collect complete data for diagnosis, including error messages. You must manually reboot the device.

To configure the exception handling method:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Specify the exception handling method.	system-failure { maintain | reboot }	Optional. By default, the device reboots when an exception occurs.

 

Displaying the exception handling method

Use the display system-failure command to display the exception handling method.

<H3C> display system-failure

 System failure handling method: reboot

Rebooting the device

CAUTION: ·       If the main system software image file is corrupted or does not exist, the device cannot reboot. You must re-specify a main system software image file, or power off the device and power it again on so the system can reboot with the backup system software image file. ·       Save your configuration before device reboot to avoid data loss. The device displays "REBOOT IN ONE MINUTE" appears one minute before it is rebooted. ·       For security purposes, if you are performing file operations at the reboot time, the system does not reboot.

 

When upgrading and maintaining the system software image file or the configuration file for the device, you must reboot the device. To reboot a device, use one of the following methods:

·           Reboot the device immediately at the CLI.

·           Schedule a reboot at the CLI to occur at a specific time and date or after a delay.

·           Power off and then power on the device again. Because this method can cause data loss, H3C recommends that you use one of the CLI methods.

To reboot the device immediately:

 

Task	Command	Remarks
Reboot the device immediately.	Reboot	Required. Available in user view.

 

To schedule a reboot for the device:

 

Task	Command	Remarks
Schedule a reboot.	·          Schedule a reboot to occur at a specific time and date: schedule reboot at hh:mm [ date ] ·          Schedule a reboot to occur after a delay: schedule reboot delay { hh:mm | mm }	Use either command. The scheduled reboot function is disabled by default. Available in user view.
