I have installed 2.7.5 on two of our IBM clusters and am seeing a new
problem with the IPMI support.
I'm getting a significant number of new RMCP+ errors and eventually
timeouts. I haven't done a lot of testing yet, but with 120 to 260
nodes the errors occur on nearly each request. With a smaller number
of nodes (~20) I don't see these errors.
I note that there are significant changes between 2.7.4 and 2.7.5 in
2.7/xCAT-server/lib/perl/xCAT/IPMI.pm regarding timeouts and IPMI
login state transitions. I didn't study the changes or the file
revision history closely.
