Slow SOL consoles
IPMI SOL on some Dell nodes (Clemson R7525, Utah R6525) can periodically get really, really, really slow. We are talking 1970s-era acoustic coupler slow here, like 110 baud-ish.
This originally happened on the Clemson AMD nodes, but we have also been experiencing it on our more recent AMD nodes. It is not just with our capture
console proxy, but also just with ipmitool
or ipmiconsole
(freeipmi
) SOL access. Sometimes a power cycle will fix it for awhile. I have noticed a couple of times that slowness is preceeded by a disconnect of the node from IPMI.
Is it an AMD thing? Legacy BIOS related?
