Changing the Default iMana 200 Password

Changing the Default iMana 200 Password

This topic describes how to change the default integrated management module (iMana 200) password.

Scenarios

Change the default iMana 200 password of the CH222 to improve the security of system operation and maintenance.

NOTE:
  • Ensure that the password complexity check is enabled. The password complexity check is enabled by default.
  • For security purposes, change the initial password upon the first login, and then change the password regularly.

Impact on the System

This operation has no adverse impact on the system.

Prerequisites

Conditions

You have installed the high-density cable to the compute node.

Data

Default iMana 200 user name and password are shown in Table 4-3.

Table 4-3 Default iMana 200 User Name and Password

Default iMana 200 User Name and Password

Description

  • User name: root
  • Password: Huawei12#$

The default user for the iMana 200 system belongs to the administrator group. The default user can access all resources in the iMana 200 system and perform all available functions.

Tools

If you want to log in to a server CLI over a serial port, prepare the following:

  • PC with an RS232 serial port.
  • DB9-RJ45 cable.

Workflow

Figure 4-5 shows the process for Changing the Password for a iMana 200 User.

Figure 4-5 Changing the Password for a iMana 200 User

Procedure

  1. Connect the serial port of the high-density port to the serial port of a PC with a serial cable.

    NOTE:

    If you cannot log in to the compute node over a serial port, log in by using the method described in Logging In to a Compute Node or a Switch Module over SOL.

  2. Log in to the compute node over a serial port by using the PuTTY. For details, see Logging In to the Server Over a Serial Port by Using the PuTTY.

    Key communication parameters:

    • Serial Line to connect to: COMn
    • Speed (baud): 115200
    • Data bits: 8
    • Stop bits: 1
    • Parity: None
    • Flow control: None

    n indicates the serial port number, and the value is an integer.

    You can log in to the operating system (OS) or iMana 200 after logging in to a compute node.

    • You have logged in to the iMana 200 command-line interface (CLI) if the following information is displayed:
      Wind River Linux release 3.0 
       Kernel 2.6.27_stm23_003 on armv5tejl (console) 
       BMC login:
    • You have logged in to the OS CLI if the following information is displayed:
      linux-SMM-Test1:~#

      Test1 on the left of the prompt indicates the OS name. The value varies according to the OS name set by users.

  3. Determine whether you have logged in to the iMana 200 CLI.

    • If yes, go to 8.
    • If not, go to 4.

  4. Connect the RS-232 serial port on the PC and the COM port on the active MM910 by using a DB9-RJ45 cable.
  5. Log in to the MM910 CLI by using a serial port communication tool.

    The key communication parameters are as follows:

    • Serial Line to connect to: COMn
    • Speed (baud): 115200
    • Data bits: 8
    • Stop bits: 1
    • Parity: None
    • Flow control: None

    n indicates the serial port number, and the value is an integer.

    The PuTTY is used to log in to the MM910 CLI. For details, see Logging In to the Server Over a Serial Port by Using the PuTTY.

  6. Run the following command to switch to the iMana 200:

    smmset -l bladeN -d switchcom -v 4

    For example, if the slot number is 16, run the following command:

    smmset -l blade16 -d switchcom -v 4

    The following information is displayed, indicating that the interface is successfully switched.
    Success

  7. Log in to the iMana 200 of the compute node again over the serial port. For details, see 1 and 2.
  8. Enter the iMana 200 user name and password.
  9. Run the following command to check the iMana 200 users and rights assigned to the users:

    root@BMC:/#ipmcget -d userlist

  10. Run the following command to change the password for a iMana 200 user:

    ipmcset -d password -v username

    For example, to change the password of the user root, run the following command:

    ipmcset -d password -v root

  11. Enter the current user password (default password is Huawei12#$).
  12. Set a new password.
  13. Enter the new password again.

    The following information is displayed, indicating that the password is successfully changed.

    Set user password successfully.
