Introduction

HDM supports memory intelligent repair, allowing users to limit OS access to faulty memory pages to prevent anomalies during access. Users can view the number of repairs and repair records from the HDM Web interface. This feature enhances the stability and reliability of the system. The following information describes the typical configuration of the memory intelligent repair feature in H3C HDM management software.

Prerequisites

Procedures and information in the document might be slightly different depending on the software or hardware version of the device.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of memory intelligent repair.

Application scenarios

This document applies to using the memory intelligent repair function provided by HDM to prevent potential memory errors on the server. Only servers installed with Intel processors support the memory intelligent repair feature.

Example: Configuring memory intelligent repair

Network configuration

As shown in Figure 1, the HDM management interface of the H3C UniServer R4900 G6 server (hereafter referred to as R4900 G6) connects to the PC through the switch. Users can log in to the HDM Web interface through the PC to perform storage management.

·     The information related to the HDM management software for the R4900 G6 server is as follows:

¡     IP address: 192.168.20.177

¡     Administrator account: admin

¡     Administrator cipher: Password@_

·     PC IP address: 10.41.50.29

Analysis

Log into the HDM Web interface of the R4900 G6 and use the intelligent monitoring menu under O&M diagnostics to perform memory intelligent repair operations.

Software versions used

This configuration example was created and verified on HDM2-1.54.

Procedure

Logging into the HDM Web interface

1.     Open a browser on the PC and enter IP address 192.168.20.177 in the address bar to access the HDM Web interface. Enter the default administrator username admin and password Password@_ to log into HDM Web.

Performing memory intelligent repair

1.     Navigate to the O&M Diagnosis > Intelligent Monitoring page.

2.     Enable memory intelligent repair. By default, intelligent memory repair is enabled.

3.     Select DIMMs from the Select DIMMs field. To select all DIMMs in the repair records, click the  icon.

4.     To hide the repair record marks in the graph, click Repair record. By default, the repair record marks are displayed. The larger a mark, the more the repair times of the DIMM in the slot at the corresponding time.

Setting the memory intelligent repair policy

1.     Navigate to the O&M Diagnosis > Intelligent Monitoring page.

2.     Enable memory intelligent repair. By default, intelligent memory repair is enabled.

3.     Click the button to the right of the memory intelligent repair feature. In the dialog box that opens, perform the following tasks:

4.     Select a page size in the PageSize field. The default is 4KB/page.

5.     Set the upper limit of memory capacity that can be isolated in the Control level field.

Verifying the configuration

1.     Navigate to the O&M Diagnosis > Intelligent Monitoring page.

2.     Enable memory intelligent repair. By default, intelligent memory repair is enabled.

3.     Click the button to the right of the memory intelligent repair feature. In the dialog box that opens, perform the following tasks:

4.     Select a page size in the PageSize field to 4KB/page.

5.     Set the upper limit of memory capacity that can be isolated in the Control level field to level 2.

6.     Simulate memory error scenarios through the applet, and inject memory CEs multiple times.

Figure 8 Injecting CEs

 

7.     View memory repair records during the memory repair process. Hover over the green identifier to see the location and number of memory repairs.

Figure 9 Memory repair status

 

8.     Access the applet and verify that the applet is operating correctly and the memory errors do not affect the system. Verify that the memory isolation volume increases from 0KB to 4KB.
