This is an update to my previous articles here and here on this issue.

I now have confirmation from HP that the supported OS’s for iSCSI Boot on the Blades are RHEL (versions 4 & 5) and SUSE (versions 9 & 10). There is no Microsoft or VMWare support at this time.

This is an update to this article on the IBM HS21 BIOS 1.07B.

IBM has confirmed to me that this is a problem that should be addressed in another BIOS patch. The only OS that seems to be affected is Red Hat. According to IBM support, it turns out that the BIOS looks at the stepping levels of the chips and if the second CPU level is different than the fist CPU level, it will “mask” them to the OS so this problem will be avoided.

For some reason, there is a bug in the code as of 1.07B that this doesn’t happen. It has been confirmed and should be corrected shortly.

UPDATE: This article has been updated here.

This is a follow up to my previous article about HP Blades not booting iSCSI. I have learned that the HP Blades do boot (and are supported!) some Linux OS’s. Microsoft is still not supported and I don’t have the official word on VMWare yet. I should have an official list next week. As soon as I get it, I will post it here.
