'Error while trying to check for restore configuration status' with CMM Initial Setup Wizard - IBM Flex System Enterprise Chassis (8721)

Resolving The Problem

Source

RETAIN tip: H206591

Symptom

The error listed here will be encountered in the conditions described:

This occurs if:

• Hypertext Transfer Protocol over Secure Socket Layer (HTTPS) protocol is used (instead of Hypertext Transfer Protocol (HTTP))
  
• Running Initial Configuration Wizard
  
• Reaching 'import existing configuration' step on the wizard
  

There are multiple ways of running the Initial Configuration Wizard:

• Logging in for the first time
  
• Logging in after resetting Chassis Management Module (CMM) to factory defaults
  
• Clicking on Initial Setup Wizard button from main menu, Mgt Module Management, Configuration
  

Affected configurations

The system may be any of the following IBM servers:

• Flex System Enterprise Chassis, type 7893, any model
• Flex System Enterprise Chassis, type 8721, any model
• Flex System Enterprise Chassis, type 8724, any model

The system is configured with one or more of the following IBM Options:

• Flex System Chassis Management Module, Option part number 68Y7029, any replacement part number (CRU)

This tip is not software specific.

The Build ID: 2PET10I and earlier firmware for the CMM is affected.

The system has the symptom described above.

Solution

This behavior was fixed in CMM firmware version 1.40.0K Build ID: 2PET10K.

The file is or will be available by selecting the appropriate Product Group, type of System, Product name, Product machine type, and Operating system on IBM Support's Fix Central web page, at the following URL:

Workaround

This workaround offers users a possibility of running the Web Wizard and avoiding the previously mentioned error:

1. Temporarily configure the web to use HTTP.
   
2. Connect through Command Line Interface (CLI) (telnet/Secure Shell (SSH)), then issue these commands:
   
   

   system> env -T MM[P] OK system:MM[1]> ports -HTTPse off OK

3. Open the browser and connect through HTTP. When the wizard is used, it will not generate the error.
   
4. After this step, continue using HTTPS by issuing these commands from CLI (telnet/SSH):
   
   

   system> env -T MM[P] OK system:MM[1]> ports -HTTPse on OK

Additional information

The issue is caused by the configuration file containing the following command, which re-generates every Secure Sockets Layer (SSL) certificate and then restarts all services that use them:

This includes the web server, which is going to use a different certificate after it restarts, so the initial handshake between the browser and CMM is no longer valid. As a consequence, the user's browser no longer will be able to issue any new Ajax requests to CMM and will report an error for each such trial.
