[Linux_hpc_swstack] Serial / Remote KVM Questions with X6250s
Hello, I have a few queries regarding serial console and remote KVM access to X6250 blades. I''m currently running BIOS version 1ADPI040 and BMC version 4.0.52 on a group of X6250s. I''m using conman to access their serial terminals through the SMASH CLI with the updated expect script that''s attached to the following message: http://lists.lustre.org/pipermail/linux_hpc_swstack/2008-August/000065.html I''m also using the ELOM Java Web Start remote KVM software to access the the blades'' remote KVMs. Remote KVM and serial access is simultaneously available. All of this stuff works for the most part, but there are a few things I''d like to ask about: Serial Access ============= * The blades seem to be capped at 9600 bps for their serial connection (see the attached serial-bios.png). Is this really all that''s possible in terms of serial speed? I frequently observe nodes over a serial connection that are spewing lots of stuff to their console, and a faster serial connection would be very valuable to me. * Though access to a blade''s serial port through the SMASH CLI seems to be a fine mechanism for out-of-band console, I''m also interested in exploring serial-over-LAN via IPMI (with freeipmi specifically), but I haven''t been able to get this to work. It''s advertized as working in the Sun docs. Am I doing something wrong with "ipmiconsole -W authcap -h sp-hostname -u root -p changeme"? It doesn''t work for me. Should I expect it to? Remote KVM Access ================= * Accessing the BIOS setup screen from the remote KVM software is very touchy. E.g., a single "right arrow" keystroke on my keyboard often gets translated into multiple keystrokes on the remote machine. This makes adjusting BIOS settings via the remote KVM a very frustrating process. Is there any way to improve this interaction? I note that there''s a VGA animation always churning across the top margin of the BIOS setup screen. Is the extra bandwidth needed for this animation messing with the interactivity? If so, is there a way to disable the animation? Thanks, -Matthew -------------- next part -------------- A non-text attachment was scrubbed...
