IPMI device driver support for Linux

To access baseboard management controller settings, use either the OSA or MSI device driver and its corresponding Lenovo IPMI mapping layer. You can also use the OpenIPMI device driver that comes in many Linux distributions.


  1. Due to a timing issue, the ASU does not support the OpenIPMI device driver contained in Red Hat Enterprise Linux 3 Update 6 and Update 7. To use these versions of Linux, the OSA IPMI mapping layer is required.
  2. For an IBM System x3950 M2 server (multi-node configuration), the OpenIPMI device driver is the only supported IPMI driver.
