Background Information
BIOS policy is a policy that automates the configuration of BIOS settings. You can create one or more BIOS
policies which contain a specific grouping of BIOS settings that match the needs of a server or set of servers.
If you do not specify a BIOS policy for a server, the default BIOS settings are applied to the server. However,
these default BIOS settings can themselves be configured as per need. If a BIOS policy is specified, the policy
takes precedence over the BIOS default settings.
Any change made to the default BIOS settings does not affect a server that has a BIOS policy associated with
it because the BIOS policy takes precedence over the default BIOS settings. However, in the BIOS policy, if
the user leaves the value as platform−default, the UCS manager refers to that particular platforms BIOS
defaults (Servers > Policies > BIOS Defaults), and uses the value specified in the BIOS defaults.
In such cases it is possible for a user to achieve the usage of both BIOS policy and BIOS defaults. This is
required because some users might want to customize only a few settings in policy, and use BIOS default
values for the rest of the settings.
For example, if the user creates a BIOS policy 'test−policy' and specifies these values:
•
'disabled' for Turbo boost
•
'platform−default' for Hyper Threading
And the BIOS defaults for the platform have these values:
•
'enabled ' for Turbo boost
•
'enabled' for Hyper Threading
The net effect of this is Turbo boost set as 'disabled' and Hyper Threading set as 'enabled'.
When a configuration change is made via a BIOS policy or via default BIOS settings, the UCS manager
immediately pushes these changes to the CIMC buffer. These changes take effect only after the server is
rebooted.
