Hi Ansgar, A> Hello List, what is the preferred way to power control nodes? A> IPMI setup is done by qluman, but there does not seem to be a way A> to control nodes from the GUI. I've found ql-remote-control, but A> it complains about a missing config file, and I did not find an A> example file to explain its syntax. currently Qlustar/QluMan just configures the IPMI interface's IP automatically and registers it including its hostname (<node>-ipmi per default) with NIS. For power control you have two options: a) Just use ipmipower from the cmd line. b) Create a custom command with the RXEngine, e.g. Example command to be entered in the command editor (substitute <user>/<pwd>): --------------------------------------------------------- hostlist="$(hostlist-expand %1)" for host in $hostlist; do ipmipower -h $host-ipmi -u $<user> -p <pwd> --cycle done --------------------------------------------------------- Make sure you select 'Headnode' as the 'Execute on:' option. Hope that helps. Best, Roland

Hi, Hmm. The hostname is there, but the interfaces are not configured -- they still carry their old IPs. I guess I'll have to investigate what goes wrong. Where is the configuration implemented? Are there any logs? Thanks, A. -- Ansgar Esztermann Sysadmin Dep. Theoretical and Computational Biophysics http://www.mpibpc.mpg.de/grubmueller/esztermann
