My BL490c G6 blades were unable to get network connectivity to our chassis. I had setup all the networking in HP Virtual Connect, but 6 blades worked, and 9 did not (we only purchased 15, not 16, don’t ask)
The error I received was different depending on the OS I was loading.
ESX 4.0 Update 1 gave this error: “The script 32.networking-drivers failed to execute and the installation can not continue.”
ESX 4.0 (no update 1) gave this error: Network ports Disconnected.
I was able to isolate this to a blade specific issue by swapping blades 4 and 6 and the issue followed the blades, not the bay. There are 4 types of firmware on these HP blades that I can see. BIOS, iLo, Qlogic(HBA), BC (nic). The UI shows everything but the NIC firmware version. All other blades with the latest Nic BIOS do not have any active network ports. If I downgrade them from 2.2.4 to 2.2.2(more specifically the Bootcode from 5.0.11 to 4.8.0), then they work(problem solved). It’s a real pain to see the HP Nic Bios since it only shows up when booting from the HP firmware CD. I do have the latest firmware on my c7000 chassis and flex10 switches. Just to verify this was a blade specific issue, I also swapped hard drives from a non working blade to a working blade, the issue followed the blade again.
I think I have this solved, I’ve “fixed” 5 blades so far by downgrading them, the only way I can find to downgrade the NIC bios is from the HP firmware boot CD, 8.7 has 2.2.4 and 8.6 has 2.2.2. There is a version 2.2.3, but best I can tell it’s not easy to install it, it must be done from inside a guest OS(no bootable CD) and ESX 4 Update1 does not install because of this error, I’d have to install another OS, then change FW version, then reload the blade.
I have an open HP case to get this resolved, hopefully we can get an updated firmware soon.
