introduce no more than two new release levels per year. These release levels will be
supported by service packs. Service packs are intended to contain only firmware fixes and
not to introduce new function. A
If the system is managed by a management console, you will use the management console
for firmware updates. Using the management console allows you to take advantage of the
Concurrent Firmware Maintenance (CFM) option when concurrent service packs are
available. CFM is the IBM term used to describe the IBM Power Systems firmware updates
that can be partially or wholly concurrent or nondisruptive. With the introduction of CFM, IBM
is significantly increasing a client's opportunity to stay on a given release level for longer
periods of time. Clients that want maximum stability can defer until there is a compelling
reason to upgrade, such as the following reasons
A release level is approaching its end-of-service date (that is, it has been available for
about a year and hence will go out of service support soon).
Move a system to a more standardized release level when there are multiple systems in
an environment with similar hardware.
A new release has new functionality that is needed in the environment.
A scheduled maintenance action will cause a platform reboot, which provides an
opportunity to also upgrade to a new firmware release.
The updating and upgrading of system firmware depends on several factors, such as whether
the system is stand-alone or managed by a management console, the current firmware
installed, and what operating systems are running on the system. These scenarios and the
associated installation instructions are comprehensively outlined in the firmware section of

Repair and verify system
Repair and verify (R&V) is a system used to guide a service provider step-by-step through the
process of repairing a system and verifying that the problem has been repaired. The steps
are customized in the appropriate sequence for the particular repair for the specific system
being repaired. The following scenarios are covered by repair and verify:
Replacing a defective field-replaceable unit (FRU) or a customer-replaceable unit (CRU)
Reattaching a loose or disconnected component
Correcting a configuration error
Removing or replacing an incompatible FRU
Updating firmware, device drivers, operating systems, middleware components, and IBM
applications after replacing a part
Repair and verify procedures can be used by both service representative providers who are
familiar with the task and those who are not. Education-on-demand content is placed in the
procedure at the appropriate locations. Throughout the repair and verify procedure, repair
history is collected and provided to the Service and Support Problem Management Database
for storage with the serviceable event, to ensure that the guided maintenance procedures are
operating correctly.
If a server is managed by a management console, then many of the repair and verify
procedures are done from the management console. If the FRU to be replaced is a PCI
service pack
is an update to an existing release level.
