In the course of updating all of our HP BladeSystem blades (BL465c) servers over the last few weeks, I’ve stumbled across some interesting things. For example, you can updated all the iLO cards at once if you have an Onboard Administrator (OA), a TFTP server, and a little XML knowhow…
1 2 3 4 5 6 7
This gets saved as an XML file on the TFTP server, I named it update_firmware.xml. The
PASSWORD fields do not matter as single sign-on is used from the OA. The iLO update binary is put on the TFTP server as well (you should use the version applicable to the hardware you’re updating). Then comes the easy bit. SSH to the Onboard Administrator, and execute the hponcfg command as such:
If you only need to update a single blade, change
ALL to the blade number. Otherwise, this will download the iLO firmware update, push it to each of the iLO cards in the BladeSystem chassis, and then restart them. This will not impact the running server. You should see output like this once it has started:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34
And that’s it, the magic is done. Using hponcfg is possible from Windows as well when updating the local machines, so it’s quite possible to use the same XML (though I’ve not tested it).
