A tool for viewing/setting bios_settings for Weka servers
usage: bios_tool.py [-h] [-c [HOSTCONFIGFILE]] [-b [BIOS]] [--fix] [--reboot] [--dump] [--diff DIFF DIFF] [-v]
View/Change BIOS Settings on servers
optional arguments:
-h, --help show this help message and exit
-c [HOSTCONFIGFILE], --hostconfigfile [HOSTCONFIGFILE]
filename of host config file
-b [BIOS], --bios [BIOS]
bios configuration filename
--fix Correct any bios settings that do not match the definition
--reboot Reboot server if changes have been made
--dump Print out BIOS settings only
--diff DIFF DIFF Compare 2 hosts
There are 2 configuration files for bios_tool: a host configuration file ("host_config.yml") and a BIOS settings configuration file ("bios_config.yml") You can either use these default names or override the configuration file names using the provided command-line switches, -c/--hostconfigfile and -b/--bios.
The host_config.yml defines the list of hosts, and their logon credentials for the BMC (ipmi, iLO, iDRAC).
The format standard YAML, as such:
hosts:
# Hpe servers
- name: 172.29.3.1
user: Administrator
password: Administrator
- name: 172.29.3.2
user: Administrator
password: Administrator
You should set all the servers you want to work with here. Note they may have different passwords for each server.
The bios_config.yml defines the BIOS settings that you want set on the servers that are defined in the host_config.yml file.
Again, the format is standard YAML, as such:
server-manufacturer:
architecture:
setting: value
setting: value
architecture2:
setting: value
setting: value
The server-manufacturer is matched to the manufacturer ("Oem") listed in the RedFish data so this tool can be used with any manufacturer that supports RedFish. Currently known manufacturer names are "Dell", "Hpe", and "Supermicro" and defaults for these manufacturers are in the example file.
The architecture can be either "AMD" or "Intel". No other architectures are currently supported.
See the provided bios_config.yml for a full example, but here's what it looks like:
Dell:
AMD: {}
Intel:
PackageCStates: Enabled
ProcC1E: Disabled
ProcCStates: Disabled
ProcPwrPerf: MaxPerf
SecureBoot: Disabled
SriovGlobalEnable: Enabled
SubNumaCluster: Disabled
WorkloadConfiguration: Balance
WorkloadProfile: NotConfigured
With no command-line overrides, bios_tool will scan the hosts in the host_config.yml and note where they differ (if they differ) from the settings in the bios_settings.yml file. No changes are made to the servers (read-only mode)
Example output:
Fetching BIOS settings of host 172.29.3.1
Fetching BIOS settings of host 172.29.3.2
Fetching BIOS settings of host 172.29.3.3
[...snip...]
No changes are needed on 172.29.3.1
No changes are needed on 172.29.3.2
No changes are needed on 172.29.3.3
[...snip...]
172.29.3.4: BIOS setting ApplicationPowerBoost is Enabled, but should be Disabled
172.29.3.4: BIOS setting CStateEfficiencyMode is Enabled, but should be Disabled
172.29.3.4: BIOS setting DataFabricCStateEnable is Auto, but should be Disabled
172.29.3.4: BIOS setting DeterminismControl is DeterminismCtrlAuto, but should be DeterminismCtrlManual
[...snip...]
Using the --fix command line option will cause the tool to make the settings to the bios as defined in the bios_settings.yml.
It will not reboot the server(s) unless given the --reboot option
Using a --reboot with --fix will make bios_tool reboot the servers after any changes are made.
Only servers that have been modified are rebooted (this causes them to APPLY the changes)
Using the --dump command line option will cause the tool to simply print out all the bios settings for each server. (read-only)
Using the --diff option will compare all the settings on 2 servers, and print out which settings differ.
Example diff output:
Fetching BIOS settings of host 172.29.3.1
Fetching BIOS settings of host 172.29.3.6
Settings that are different between the servers:
Setting 172.29.3.1 172.29.3.6
