Mike/Steve C/all,
Our code does have logic regarding kernel versions as Steve C
mentioned. I have my devs looking into if they have already addressed these
concerns.

I tried to reproduce the problem with 3.1.0-rc7-686-pae from
experimental as you requested, but I failed. The problem is that
hpacucli does not find any controllers with this kernel :-( I used the
latest available hpacucli version (8.75-12.0). This version definitely
works with 2.6.39. I tried strace-ing hpacucli but that didn't give me
any clues. It was looking for /dev/cciss/c0d0/cciss, which is weird
and might indicate that the 3.1 environment makes the hpacucli device
search fail....
Weird. Stephen et al: any ideas?
Yeah I suspect I know what's going on. There was some code
in hpaaculi which was asking the question "Is this a 2.4 kernel?
Or is this a 2.6 kernel?" It didn't consider the possibility of
a 3.x kernel, and in the face of a 3.x kernel, it just kind of
gave up.
Pretty sure this bug is fixed in a released version of hpacucli
because rhel6.1 uses a 3.x kernel, and I know we support that.
Bill Kilcoyne might know the specifics.
RHEL 6 will be sticking with what is nominally version 2.6.32, although
RH continues to backport large changes from later versions. The first
stable distribution with a 3.x kernel will presumably be Ubuntu 11.10
'oneiric'.
Stable update 3.0.4 added a process personality flag that causes the
kernel to report version numbers beginning '2.6.', and the 'setarch'
command in util-linux has been updated to allow setting this flag.
However. neither Debian nor Ubuntu has this new version of util-linux
yet.
Ben.
It's sles11 sp2 that uses a 3.0.x kernel.
