remote reset and serial console for the Linux Support "lab" machines: ---+++ Serial console refslc-3-* and lxcert-* are connected to =lxcnetlab1= with the standard SLAC serial console server setup, i.e. <pre>ssh lcert-i386.headnode.cern.ch console machinename</pre> (use "console -x" to get a list, escape character is =^Ec=, i.e. =^Ec.= to disconnect. See http://service-console.web.cern.ch/service-console/ for more.) ---+++ IA64 management board interface Available commands (use =^B= to get back to main menu): * reset: =cm= , =rs= , (confirm: =Y=) (exit: =^B=) (connect to console =co=) * power: =cm= , =pc= * console: =co= (*not* =se=) Entering the menu may require a username (=mopladmin=) and password (see !AndreasH or Jan). Try without first. Hint: the OS sees the serial console as =ttyS3=. ---+++ remote reset for i386, x86_64 To reset a non-ia64 machine, login to =lxcnetlab1=, then eg. <pre> $ /usr/local/resetboard/push-button ttyS0 1 4 2 </pre> will reset board #1, port #4 for two seconds. Cables #1,2,3,4 are hooked up to resetboard ports number 1,2,3 and 4 respectively. =/usr/local/resetboard/layout.txt= has the mapping between ports and machines. *Please be careful* to reset the right machine only. Please be *DOUBLY CAREFUL* when cabling new machines to the resetboard thingy.
