We have two important production servers on (fairly ancient) Supermicro X8DT6 motherboards. I've never updated BMC firmware before, but I'm keen to see if we can get some HTML5 kvm consoles running on these machines, and to know if the upgrade is safe to do while the server continues to operate.
The BMCs are running
Firmware Revision : 2.08
Firmware Build Time : Dec 2 2011 19:21:51
according to the BMC web interface (the revision is confirmed in ipmitool).
It appears that Supermicro has updated IPMI firmware version 2.22 available for the X8DT6-F motherboard which I assume is a family member of the X8DT6.
It appears possible to upload the firmware file (X8DT6222.ima in this case) via the BMC web interface. The document with the download bundle has the following note, however:
2.0 System will reboot after upgrade complete.
Does that reboot refers only to the BMC, or to the whole server?
A BMC update requires a reboot of the whole server, so you will have to schedule a downtime for it on your production servers.
