Here are some very important updates for HP Blade Enclosures, I have also included iLO Updates as they are very important to keep up to date. Remember iLO and the Onboard Administrator firmwares can be updated live with no impact to the enclosure, ESX/vSphere server, Windows Servers, or Virtual Machine’s on ESX/vSphere. The Power Management Controller will have to be updated via a Bootable firmware CD.
HP Onboard Administrator for c-Class Blades is at rev 2.51 (May 28 2009)
HP ILO is at revision 1.7.8 (June 16th 2009)
HP Power Management Controller rev 3.4(B) (June 17th 2009) (haven’t figured out how to apply this one)
Here is the whole HP Blade System Online Firmware Bundle
If the files are out of date, which they shouldn’t be..
