BMCVersion

BMCVersion represents a BMC Version upgrade operation for a physical server's Manager. It updates the BMC Version on physical server's BMC.

Key Points

• BMCVersion maps a BMC version required for a given server's BMC.
  • BMCVersion Spec contains the required details to upgrade the BMC to required version.
• Only one BMCVersion can be active per BMC at a time.
• BMCVersion starts the version upgrade of the BMC using redfish SimpleUpgrade API.
• BMCVersion handles reboots of BMC.
• BMCVersion requests for Maintenance if ServerMaintenancePolicy is set to "OwnerApproval".
• OnceBMCVersion moves to Failed state, It stays in this state unless Manually moved out of this state.

Workflow

1. A separate operator (e.g., bmcVersionSet) or user creates a BMCVersion resource referencing a specific BMC.
2. Provided settings are checked against the current BMC version.
3. If version is same as on the server's BMC, the state is moved to Completed.
4. If the version needs upgrade, BMCVersion checks the current version of BMC and if required version is lower than the requested, BMCVersion moves the state to Failed
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. BMCVersion issues the BMC upgrade using redfish "SimpleUpgrade" API. and monitors the upgrade task created by the API.
7. BMCVersion moves to Failed state:
   • If SimpleUpgade is issued but unable to get the task to monitor the progress of BMC upgrade
   • If the upgrade task created by SimpleUpgade fails and does not reach completed state.
   • If the BMC version requested is lower than that of the current BMC version
8. BMCVersion moves to reboot the BMC once the upgrade task has been completed.
9. BMCVersion verfiy the BMC version post reboot, removes the ServerMaintenance resource if created by self. and transistion to Completed state
10. Any further update to the BMCVersion Spec will restart the process.
