Fails to login CU or OMU Portal Highlighted

Hello, dear!

Have a good day!

Today I will share with you how to deal with the problem that fails to login CU or OMU portal.

Issue Description

In daily issue handling, there was a lot of login CU or OMU failed issues.

Handling Process

At first, we should analysis the login flow, from the process flow diagram, we found that there are two main flow in the login process:

1. If we log in to CU, it is CU connects to SMU through the network; if we login OMU portal, it isPortal connect to OMU.

2. SMU or OMU authenticates the user.

   
   

So we should consider the below reasons for login failed:

• The setting of the browser

• The network issue
  

• The platform modules issue
  

• Other issues
  

So the solution is as below:

1. We should read the error information, many errors can show the direct reason. For example, “The maximum number of logins configured to use this account at the same time has been reached”, this means the account has login at other sites, so we need to open the multi-login permission. But when display “network exception”, we should pay attention that may not because of network issues.
   

2. When it displayed “network exception”, we should try to ping VCN:
   

• If it can’t ping, we should check the network issue.
  

• If it can ping, go on with the next step.
  

  3. OMU portal login error, we should check the browser configuration:

1. Open IE,choose tools > internet option > advance.
   

2. Unclick use SSL 2.0 and use SSL 3.0, and choose use TLS 1.1 and use TSL 1.2.
   

3. Click OK.
   

4. Then clean the cache, try again.
   

  4. User permission issue: please try to login with default user.

VCN module issue: login VCN use SSH, check SMU and OMU process. The details can be found in the document.

Other issues: check if the root directory is used 100%, if it is, please contact Huawei engineer to clean the root directory.

This is all, thanks!
