A BMC firmware update failure can occur for a number of reasons. If a BMC firmware update fails, you may not be able to boot Data ONTAP.
Considerations
A firmware update failure can occur for one of the following reasons:
- The firmware image is incorrect or corrupted.
- A communication error occurred while sending firmware to the BMC.
- The update failed when you attempted to install the new firmware at the BMC.
- The storage system was reset during the update.
- There was a power loss during update.
Steps
-
A/C power-cycle the storage system.
- After the system is powered on again, update the BMC firmware by entering the following command from the boot environment prompt: update_bmc
Note: If a previous power failure caused the system to boot from the backup firmware and halt at the boot environment prompt, repeat the update_bmc command at the boot environment prompt.
The update_bmc macro automatically updates the BMC firmware from the image on the CompactFlash card.
- After the BMC firmware is updated, enter following command from the boot environment prompt to restart the system: bye
- Reboot the BMC by entering the following command at the storage system prompt: bmc reboot
- If the BMC still does not reboot, run diagnostics on the BMC.
- If the BMC is not operational, contact technical support for assistance.
Note: If a BMC firmware update fails when Data ONTAP is running, Data ONTAP will try to recover the BMC by rebooting it. If the reboot fails, a message [asup.msg.bmc.heartbeat.stops:critical] is sent and the storage system is shut down. Contact technical support for assistance.
