Hi,

I also have problems with dhcp. I have linux runnind dhcp server and
opensm. Some windows nodes seem to ignore dhcpoffer packets.

Anatoly.

Hi Folks,

I've been seeing fairly consistent issues with DHCP getting "hung". The
scenario is this: cluster configured with DHCP server and OpenSM on head
node, serving addresses to IPoIB.  If some compute nodes get rebooted a
couple times, they (and other nodes) are no longer able to get DHCP
addresses.  This seems to happen with both opensm.exe and
opensm_3_0_0.exe, so it's not clear that this is an SM issue.  It could
be an issue in IPoIB.  In any case, restarting the SM fixes things.

Still trying to narrow down what causes this, but thought I'd bring this
up now in case someone else has seen it too.
