Default Host Firmware Policy After Upgrade

A.

In a Cisco Unified Computing System (UCS) environment, a host firmware policy is used to define the firmware versions that should be used by the servers in the system. This policy can be applied to one or more service profiles, which in turn are used to configure the server's hardware and software settings.

When the UCS Manager software is upgraded, the behavior of the default host firmware policy can depend on the version being upgraded from and to. However, in general, the default policy may be affected in one of the following ways:

B. It is replaced by a new default policy without any firmware entries: In some cases, a new default host firmware policy may be introduced with the upgrade, which may not include any firmware entries. This means that the new policy is effectively "blank", and any service profiles that previously used the default policy will need to be updated to use a different policy or to have firmware entries added to the new default policy.

C. It is set to match the host firmware policy: In other cases, the upgrade process may automatically update the default policy to match the firmware version specified in the existing host firmware policy. This means that the default policy will now contain the same firmware entries as the host firmware policy, and any service profiles that use the default policy will automatically be updated to use the new firmware versions.

A. It is assigned to all the service profiles that include a host firmware policy: If the upgrade process does not modify the default policy, it will continue to be assigned to any service profiles that include a host firmware policy. This means that any service profiles that use the default policy will continue to use the same firmware versions as before the upgrade.

D. It is updated to contain the firmware entries of all the components: It is unlikely that the default host firmware policy will be updated to contain the firmware entries of all the components in the system. This would result in a very large policy that is difficult to manage, and would also make it difficult to identify which firmware versions are actually in use on each server.

In summary, the behavior of the default host firmware policy after a UCS Manager upgrade depends on the specific upgrade scenario, but it is most likely to be replaced by a new default policy without any firmware entries or set to match the host firmware policy.
