I am i the process of rolling out a HP c7000 Blade Enclosure with 12 new Servers and migrating old machines to new Blades and into the HyperV World and a MSA 2012i for Backups and Virtuals. One thing I ran into was I had the secondary OA have a Firmware mismatch with the Primary and I could not get it to Sync with the Primary OA. So I downloaded the latest Firmware for the Enclosure and checked the notes on it and it required iLo firmware 1.78 from HP. I checked all the servers and none of them had 1.78 now what do I do as 10 of the Blades are not running and have no OS on them. The 2 that I have running I did those updates and then went to searching.
What I found was you can use the OA Command line to update your Firmware on your Blades with them shutoff. So I had a little ftp server I turned on and dropped the iLo2_178.bin file into the site and then opened a command prompt and telneted into the Primary OA and ran this command.
Update iLo 1 ftp://servername or ip address/iLo2_178.bin hit enter and away it went. Just as easy as that it updated the firmware and I didn’t have to turn the machines on and install a OS. The number 1 after Update iLo is the Blade you are wanting to update or if you want to do the whole EnclosureBlades you would put All instead of the Blade number. Or you do 2 and then 3 and you get the picture. Ftp and HTTP and a Tftp server will also do the trick for presenting the Firmware to the Blade.
Til Later just Roger
