1.2 Routine Inspection-Purposes



The purposes of routine maintenance and inspection are as follows:



Find and remove the potential defects or hazards during device operating in a

timely manner. Take measures to rectify the faults to ensure normal device

operating and reduce the device fault rate.



Monitor the running status and trends of devices and networks in real time, which

improves the maintenance personnel's efficiency of handling emergencies.



Periodically maintain devices to ensure that devices run properly and that the

system runs safely, stably, and reliably.



Periodically check, test, and clean devices and back up data. This helps you find

the defects (such as natural aging, function disabling, and performance

deterioration) that occur during device operating. Take measures to handle the

defects to rectify potential faults and avoid accidents.

Page 10

1.2 Routine Inspection-Basic Rules



Name a device uniquely.



Create logs for recording the troubleshooting.



Make one change at a time, and record the change result.



Use the tools, resources, and software provided by Huawei.



Be aware of the latest updates of the operating system (OS) and

applications.



Make a reliable backup plan.



Prepare spare parts onsite. Once a component is faulty, replace it with a

new one in a timely manner.



Keep the latest network topology, which helps rectify network faults.

Page 11

1.2 Routine Inspection-Onsite Inspection



Onsite inspection includes inspection of the equipment room environment

and device running status.

Icon Description

Indicates a hazard. To prevent an electric shock, do not remove the cover of the component.

Warning: All components with this icon have electric shock risks and there are no serviceable parts

inside these components.

Indicates a hazard. Operation of the component may cause an electric shock. There are no

serviceable parts inside the component, and therefore do not remove the cover of the component.

Warning: To prevent an electric shock, do not remove the cover of the component.

Indicates high temperatures.

Warning: Be careful and do not touch the component before it cools down. Otherwise, you may get

burnt.

Indicates a hazard. Misoperations may damage the device or cause personal injury.

Indicates the external grounding of the device. Both ends of a ground cable are connected to

different devices, and the devices must be grounded by connecting to ground points. This ensures

proper device operating and personal safety.

Indicates the grounding inside the device. Both ends of a ground cable are connected to different

components of a devices, and the device must be grounded by connecting to ground points. This

ensures proper device operating and personal safety.

Indicates an ESD-sensitive area. Do not touch the device with bare hands. When you operate a

device in an ESD-sensitive area, take ESD measures, such as wearing an ESD wrist strap or ESD

gloves.

the server health status.



The inspection tool has the following features:



Supports the GUI and CLI.



Supports 32-bit and 64-bit OSs.



Inspects one server or servers in batches.



Exports the inspection report.



Preparations for Using the Inspection Tool

1. Console Requirements



Used to run the inspection tool, the console refers to the customer's PC or

laptop. A Windows system or a Linux system later than SUSE Linux

Enterprise Server (SLES) 11 SP1 is recommended. (For details about the

clients supported by the tool, see the user guide.)



Other auxiliary tools, such as the Excel component used to edit

configuration files in batches, the SSH tool used to upload tools to the

Linux system console, and the compression tool (such as WinRAR) used

to decompress logs.

2. Configuration Information About Servers to Be Inspected



BMC IP address, root user password, SNMP version, and port number of

each server to be inspected



For batch inspection, the list of servers to be inspected must be edited.

The .xls, .xlsx, and .xml formats are supported. This mode also supports

single-node server inspection.
