Updating Firmware Using Ironic And Redfish In The Datacenter And At The Edge

on YouTube ↗20m

" summary

Ironic uses Redfish simple update to push firmware images over HTTP/HTTPS to BMCs and is validated on Dell PowerEdge R640, R6515 and R630xd, updating iDRAC, BIOS, Intel NICs, H740P RAID and power supplies. Firmware images must be hosted on a web server reachable by the BMC or the ironic conductor; edge sites require a DHCP relay and local HTTP hosting to avoid backhaul failures. Updates run as a JSON update_firmware cleaning step on the management interface, execute sequentially with per-image wait times, can brick hardware if interrupted, and respect clean_callback_timeout 1800s unless reconfigured. Logs live in the ironic conductor and BMC job queue.
