Hi,
Sorry for posting to both lists. I have encountered a problem, whose
source I'm not sure of. This occured on a SuperMicro 1UIPMI-B in an
H8SSL-i. The system was running a 2.6.15-4 kernel.
I encountered a problem with an SOL connection that I'm thinking is either
a problem with the BMC firmware or the openipmi driver (or both?). The
error below came after some number of hours of the SOL being locked up. I
was using ipmitool version 1.8.6, checked out of cvs on Feb 24.
I'd enabled hardware flow control (as Steffen Grunewald had described on
the ipmitool list, thanks Steffen!), and had logged in over SOL, and left
a "while true ; do find /usr ; done" over the weekend. I noticed on
Sunday the console was frozen, and then on Mon morn I found:
Error sending SOL data: FAIL
SOL session closed by BMC
and the BMC was no longer on the net... I couldn't even ping it. I didn't
think to try to openipmi interface to see if the entire BMC fell down, or
if it just fell off the net. The machine also wouldn't shut down; agetty
never realised the remote console was gone, and my find process was
happily sleeping: once I'd killed it, the machine happily shut down. I'm
currently trying to reproduce.
Has anyone else done any "stress" testing and seen a BMC just fall down?
Do any openipmi developers have any pointers on where to look to see
what's hung up? Any thoughts on how to tell if this is a software problem
or a firmware problem?
Can any ipmitool developers (Hi Duncan!) offer any thoughts (I know, I
didn't give you a whole lot to go on)? From ipmitools view, the host just
went away?
Thanks!
Paul
