8.1 Firmware updates
IBM periodically makes firmware updates available for the compute node, the
management module, or expansion cards in the compute node. In a compute
node or chassis environment, there are multiple points to consider when
considering firmware updates. In some cases, the chassis and infrastructure
components can be updated concurrently, without disrupting virtual
server operations.
In this chapter, we describe methods for updating the Power Systems compute
nodes.
The simpler way to do a firmware update of a POWER processor-based compute
node requires that a supported operating system be running on the compute
node. Live Partition Mobility (LPM) can be used to avoid the disruptive nature of
firmware updates. If the node is managed by IBM Flex System Manager, the
firmware update can also be concurrent.
Firmware updates can provide fixes to previous versions and can enable new
functions. Compute node firmware typically has a prerequisite CMM firmware
level. It is best to have a program in place for reviewing the current firmware
levels of the chassis components and compute nodes to ensure the
best availability.
Firmware updates are available at IBM Fix Central web page at the
following website:

8.1.1 Firmware update methods
The firmware of the compute node can be updated in various ways:
򐂰 The IBM Flex System Manager acquires, installs, and manages firmware and
device driver updates, and monitors your compute nodes to ensure that they
remain current.
Important: To avoid problems and to maintain proper system performance,
always verify that the compute node, service processor, and diagnostic
firmware levels are consistent for all compute nodes within the IBM Flex
System Enterprise Chassis. For more information, see 8.1.4, “Verifying the
system firmware levels” on page 325.
