The process for implementing NIST 800-131A compliance for
the Lenovo Flex System differs
depending on whether you are using the IBM Flex System Manager or
the Chassis Management Module to manage a chassis.
Installing a new chassis
If you are installing a new chassis, you can set up an environment that complies with NIST 800-131A as you configure each of the devices in the chassis.
Updating an existing chassis
The procedures that you follow to update an existing chassis to support NIST 800-131A depend on the system management device that you have installed.
Switching between compatibility mode and NIST 800-131A mode
You can choose to switch between compatibility mode (which is not compliant with NIST 800-131A) and NIST 800-131A mode if you are managing a chassis through the Chassis Management Module (CMM) or through the Lenovo XClarity Administrator. However, if you are managing a chassis through the IBM Flex System Manager management node, you must reinstall the management node software to switch between modes.
