RE: [Freeipmi-devel] ipmi support with HP iLO2 servers initialsuccess! -

Chris,

In the IPMI 2.0 spec it requires that all IPMI 2.0 firmware must support an IPMI 1.5 GetChannelAuthCap command. Section 22.13 says:

BMC implementations of IP-based channels must support the Get Channel Authentication Capabilities Command

using the IPMI v1.5 packet format. BMCs that support IPMI v2.0 RMCP+ must also support the command using

the IPMI v2.0/RMCP+ format.

So the HP iLO 2 firmware isn’t fully compliant with the IPMI 2.0 spec in this case.

I guess another question I would ask, is when will ipmi 1.5 be deprecated and the default be 2.0? I was just curious when defaults should move away.

This server is a proliant dl385g5 server (amd barcelona quad core). I have also tested on a bl460g6 (proliant blade Intel 6 core).

Does HP believe this to be a bug in their firmware? Many of the tests
in the freeipmi-testing document use IPMI 1.5 specifically (instead of
IPMI 2.0), so we'll want to get this bug fixed so you can pass those
tests too.

Also, as an FYI, what motherboard are you testing on? So that I can
document this stuff.
