CMM reset

Use this information to reset the CMM.

The CMM supports three levels of reset:

  • Standard reset (restart) performs an immediate reset and restart of the CMM.
  • Service-level reset (virtual reseat) simulates removing the CMM from the chassis to remove power and then reinserting it.
  • Resetting the CMM to its factory default configuration restarts the CMM and restores the CMM to its original unconfigured state.

You can reset a CMM when you have physical access to it or by using one of the CMM management interfaces (CMM web interface or the CMM command-line interface).

Reset procedures for when you have physical access to the CMM

If you have physical access to the CMM:

Standard reset (with physical access to CMM):
You can perform a standard reset (restart) of the CMM by pressing the reset button for between 1 and 10 seconds (see CMM controls and indicators for more information).
Service-level reset (with physical access to CMM):
You can perform a service-level reset (virtual reseat) of the CMM by removing it from the chassis and then reinserting it (see Removing a Chassis Management Module 2 and Replacing a Chassis Management Module 2 for instructions).
Restore the CMM to its factory default configuration (with physical access to CMM):

You can restore the CMM to its factory default configuration by pressing the reset button for at least 10 seconds (see CMM controls and indicators for more information).

Attention
When restoring the CMM to its factory default configuration by pressing the reset button, all CMM log files and configuration settings are lost.
  • You will need to configure the CMM after restoring the CMM to its factory default configuration. Save the CMM configuration before restoring the CMM to its factory default configuration, if you intend to reuse your configuration settings (see Saving a CMM configuration for information about saving up the CMM configuration).
  • To retain the log files to assist with troubleshooting CMM problems during CMM replacement, restore the CMM to its factory default configuration using the CMM web interface or the CMM command-line interface, as described in the information that follows.
Important
Restoring the CMM to its factory default configuration takes several minutes. Do not remove power from the CMM or from the Flex System chassis while the CMM is restoring.

Reset procedures for using the CMM management interfaces

If you do not have physical access to the CMM, you can reset the CMM using the CMM web interface or the CMM command-line interface.

Standard reset (using a CMM management interface):

To performing a standard reset (restart) of the CMM using one of its management interfaces, complete one of the following procedures.

Important
All existing network connections will be temporarily lost when you reset the CMM. You will need to reconnect to the CMM after the reset completes.
  • In the CMM web interface, select Restart from the Mgt Module Management menu. See CMM management options for more information. All fields and options are fully described in the CMM web interface online help. Several restart options are available for the Lenovo Chassis Management Module 2, depending on your system configuration.
  • In the CMM CLI, use the reset command (see reset command for information about command use). Several reset command options are available for the Lenovo Chassis Management Module 2.
Service-level reset (using a CMM management interface):

To perform a service-level reset (virtual reseat) of the CMM using one of its management interfaces, complete one of the following procedures.

Attention
If you are managing your Flex System chassis using the optional Lenovo XClarity Administrator orFlex System Manager software, you must unmanage and remanage the chassis when performing service-level reset (virtual reseat) of the primary CMM. For information about using the Lenovo XClarity Administrator, see Lenovo XClarity Administrator information page. See Unmanaging a chassis and Remanaging a chassis after unmanaging in the Flex System Manager Systems Management Guide for information about using the Flex System Manager software.
  • In the CMM web interface, reset the CMM by choosing Reset > Virtual Reseat from the Service Reset tab on the Advanced Status page (select Advanced Status > Service Reset from the Service and Support menu). See Service and support options for more information. All fields and options are fully described in the CMM web interface online help.
  • In the CMM CLI, use the service -vr command (see service command for information about command use).
Restore the CMM to its factory default configuration (using a CMM management interface):

To restore the CMM to its factory default configuration using one of its management interfaces, complete one of the following procedures.

Attention
All existing network connections will be lost when you restore the CMM to its factory default configuration. You will need to configure the CMM after restoring the CMM to its factory default configuration. Save the CMM configuration before restoring the CMM to its factory default configuration, if you intend to reuse your configuration settings (see Saving a CMM configuration for information about saving up the CMM configuration).
Important
When restoring the CMM to its factory default configuration, you should retain the log files to assist with troubleshooting CMM problems during CMM replacement. Log information is retained automatically when restoring the factory default configuration using the CMM CLI and is the default selection when restoring the factory default configuration using the CMM web interface.
  • In the CMM web interface, to reset the CMM, select Reset to Defaults from the Mgt Module Management menu; then, click OK to confirm. You can remove the check from Preserve Logs , if you do not wish to save log files. See Resetting the CMM to manufacturing defaults for more information. All fields and options are fully described in the CMM web interface online help.
  • In the CMM CLI, use the clear -cfg command (see clear command for information about command use).
Important
Restoring the CMM to its factory default configuration takes several minutes. Do not remove power from the CMM or from the Lenovo Flex System chassis while the CMM is restoring.
