BIOSVersion

BIOSVersion represents a BIOS Version upgrade operation for a physical server (compute system). It updates the bios Version on physical server's BIOS.

Key Points

• BIOSVersion maps a BIOS version required for a given server's BIOS.
  • BIOSVersion Spec contains the required details to upgrade the BIOS to required version.
• Only one BIOSVersion can be active per Server at a time.
• BIOSVersion starts the version upgrade of the BIOS using redfish SimpleUpgrade API.
• BIOSVersion handles reboots of server using ServerMaintenance resource.
• OnceBIOSVersion moves to Failed state, It stays in this state unless Manually moved out of this state.

Workflow

1. A separate operator (e.g., biosVersionSet) or user creates a BIOSVersion resource referencing a specific Server.
2. Provided BIOS Version is checked against the current BIOS version.
3. If version is same as on the server's BIOS, the state is moved to Completed.
4. If ServerMaintenance is not provided already. it requests for one and waits for the server to enter Maintenance state.
   • policy used by ServerMaintenance is to be provided through Spec ServerMaintenancePolicy in BIOSVersion
5. BIOSVersion issues the bios upgrade using redfish SimpleUpgrade API. and monitors the upgrade task created by the API.
6. the BIOSVersion moves to Failed state:
   • If SimpleUpgade is issued but unable to get the task to monitor the progress of bios upgrade
   • If the upgrade task created by SimpleUpgade fails and does not reach completed state.
   • If the bios version requested is lower than that of the current bios version
7. BIOSVersion moves to reboot the server once the upgrade task has been completed.
8. BIOSVersion verfiy the bios version post reboot, removes the ServerMaintenance resource if created by self. and transistion to Completed state
9. Any further update to the BIOSVersion Spec will restart the process.
