This policy ensures that the host firmware is identical on all servers associated with service profiles which
use the same policy. Therefore, if you move the service profile from one server to another, the firmware
versions are maintained. Also, if you change the firmware version for an endpoint in the firmware package,
new versions are applied to all the affected service profiles immediately, which could cause server reboots.
You must include this policy in a service profile, and that service profile must be associated with a server for
it to take effect.
Prerequisites
This policy is not dependent upon any other policies. However, you must ensure that the appropriate firmware
has been downloaded to the fabric interconnect. If the firmware image is not available when Cisco UCS
Manager is associating a server with a service profile, Cisco UCS Manager ignores the firmware upgrade and
completes the association.
Management Firmware Package
This policy enables you to specify a set of firmware versions that make up the management firmware package
(also known as a management firmware pack). The management firmware package includes the Cisco Integrated
Management Controller (CIMC) on the server. You do not need to use this package if you upgrade the CIMC
directly.
The firmware package is pushed to all servers associated with service profiles that include this policy. This
policy ensures that the CIMC firmware is identical on all servers associated with service profiles which use
the same policy. Therefore, if you move the service profile from one server to another, the firmware versions
are maintained.
You must include this policy in a service profile, and that service profile must be associated with a server for
it to take effect.
This policy is not dependent upon any other policies. However, you must ensure that the appropriate firmware
has been downloaded to the fabric interconnect.
Stages of a Firmware Upgrade through Service Profiles
You can use the host and management firmware package policies in service profiles to upgrade server and
adapter firmware.
If you modify a host firmware package by adding an endpoint or changing firmware versions for an existing
endpoint, Cisco UCS Manager upgrades the endpoints and reboots all servers associated with that firmware
package as soon as the changes are saved, disrupting data traffic to and from the servers.
Caution
New Service Profile
For a new service profile, this upgrade takes place over the following stages:
Firmware Package Policy Creation
During this stage, you create the host and/or management firmware packages and include them in the
appropriate firmware policies.
