Hi, on an ESS node with power cpu I can get the serial number from /proc/device-tree/system-id which is very useful sometimes On nodes with X86 architecture (Lenovo GSS or IBM ESS3XXX_) there is no such pseudo-file. Is there a simple way to get at the serial number? -- Dr. Jürgen Hannappel DESY/IT Tel. : +49 40 8998-4616 -------------- next part -------------- A non-text attachment was scrubbed...
