Logging in to the IMM2 Web interface

Use these instructions to log in to the IMM2 web interface.

Notes
  • The IMM2 user name and password are provisioned through the CMM. To use tools such as Advanced Settings Utility (ASU) for out-of-band communications, you must define local user accounts from the IMM Web interface. To define local user accounts from the IMM Web interface, click IMM Management > Users.
    Note
    The local user accounts are valid only for accessing the IMM Web interface on this compute node. However, if you back up the IMM configuration, that backup will not contain the local user accounts that were created from the IMM user interface.
  • If you are logging in to the IMM2 for the first time after installation, the IMM2 defaults to a Dynamic Host Configuration Protocol (DHCP). If a DHCP host is not available, the IMM2 assigns a static IP address of 192.168.70.100 for the chassis and 192.168.70.10x for the compute node. For example, bay 1 in the compute node is 192.168.70.101, bay 2 in the compute node is 192.168.70.102, and so forth.
  • You can also assign IP addresses through the CMM ifconfig command. For more information about the CMM ifconfig command, see the "Flex System Chassis Management Module: Command-Line Interface Reference Guide". To change the IP address and configuration method, complete the following steps:
    1. From the CMM web interface, click Chassis Management.
    2. Click Component IP Configuration.
    3. Click the device name.
    4. Click the IPv4 or IPv6 tab.
  • The IMM2 user ID and password are provisioned through the CMM. Use the login account of the CMM to log in to the IMM2 web interface.
  • If the CMM and compute nodes are set to use DHCP, and the CMM loses connectivity to the network, the CMM attempts to acquire a new IP address when network connectivity is restored. The compute nodes will not attempt to acquire an IP address again, and the compute nodes continue to use their existing IP addresses. Therefore, if you experience network problems on compute nodes after connectivity between the CMM and the network has been restored, you might have to reset the system-management processor on each of the compute nodes in the chassis (including Flex System Manager management software, if it is installed).
  • You must set the CMM to use the Secure security policy for the IMM2 to power on the compute node and for the IMM2 to function properly. See Secure security policy in the Lenovo Flex System Chassis Management Module Installation Guide.

To log in to the IMM2 web interface, complete the following steps:

  1. Open a web browser and in the Address or URL field, type the IP address or host name of the IMM2 to which you want to connect.
  2. On the Login page, type the CMM user name and CMM password. You are then directed to the main page of the IMM2 web interface. If you are using the IMM2 for the first time, you can obtain the user name and password from your system administrator. All login attempts are documented in the IMM event log.
  3. Click IMM Management > User > Global Login Settings > General to modify the timeout value. The IMM2 will log you out of the web interface if your browser is inactive for the number of minutes that you have specified for the timeout period
