Displaying the operational statistics about 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(*.tar.gz)[flash:/diag_H3C_20220714-111033.tar.gz]:

Diagnostic information is outputting to flash:/diag_H3C_20220714-111033.tar.gz.

Please wait...

Save successfully.

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

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

Rebooting the device

To reboot the device, use one of the following methods:

·     Reboot the device at the CLI. You can remotely reboot the device in either of the following ways:

¡     Reboot the device immediately by using the reboot command.

¡     Schedule a reboot to occur at a specific time or date or after a delay by using the schedule reboot command.

·     Power off and power on the device. This method cuts off the power of the device forcibly, which might cause data loss. It is the least-preferred method.

Restrictions and guidelines

·     Before you reboot the device, perform the following tasks:

¡     Use the save command to save the running configuration. For more information about the save command, see configuration file management commands in the command references.

¡     Use the display startup and display boot-loader commands to verify that you have specified the correct next-startup configuration files and startup software images. If the main startup software image is corrupt or does not exist, a reboot failure will occur. To avoid a reboot failure, use the boot-loader file command to specify a new startup software image. For more information about the display startup and display boot-loader commands, see software upgrade commands in the command references.

·     The device will not reboot if a file is being accessed.

Configuration procedure

Rebooting the device immediately

Task	Command	Remarks
Reboot the device immediately.	reboot [ force ]	Available in user view.

 

Scheduling a reboot for the device

Task	Command	Remarks
Schedule a reboot.	·     Schedule a reboot to occur at a specific time or date: schedule reboot at time [ date ] ·     Schedule a reboot to occur after a delay: schedule reboot delay time	Use either command. By default, no reboot date or time or reboot delay time is specified. Available in user view. The most recent configuration takes effect if you execute the scheduler reboot at or scheduler reboot delay command multiple times.
