BMCSettings

BMCSettings represents a BMC Setting update operation for a physical server's BMC (compute system). It updates the BMC settings on physical server's BMC.

Key Points

• BMCSettings maps a BMC version and settings as map for a given server.
• Only one BMCSettings can be active per BMC at a time.
• BMCSettings related changes are applied once the BMC version matches with the physical server's BMC version.
• BMCSettings handles reboots of BMC
• BMCSettings requests for Maintenance if ServerMaintenancePolicy is set to "OwnerApproval".
• OnceBMCSettings moves to Failed state, It stays in this state unless Manually moved out of this state.

Workflow

1. A separate operator (e.g., bmcSettingsSet) or user creates a BMCSettings resource referencing a specific BMC
2. Provided settings are checked against the current BMC setting.
3. If settings are same as on the server, the state is moved to Applied (even if the version does not match)
4. If the settings needs update, BMCSettings check the version of BMC and if required version does not match, it waits for the BMC version to reach the spec version.
5. If "OwnerApproval" ServerMaintenancePolicy type is requested and ServerMaintenance is not provided already. it requests one per server managed by BMC and waits for all the server to enter Maintenance state.
6. Setting update process is started and the physical server's BMC is rebooted if required.
7. BMCSettings verfiy the setting has been applied and trasistions the state to Applied. removes all the ServerMaintenance resource if created by self.
8. Any further update to the BMCSettings Spec will restart the process.
9. If the BMCSettings fails to apply the bmc setting. The BMCSettings moves to Failed state until Manually moved out of this state.
