[Lerftest-ctrls] RF CPU reboot & iocConsole problems

[Wesley Moore]

Looks like at least lcls-llrfcpu02 needs to be rebooted.  Others seem likely as well.  The control room hosts aren't connecting either.  Have you heard anything from Larry?

    Hi Wesley, all,
    
    I just tried a reboot of RF CPU lcls-llrfcpu02 and it never successfully 
    re-booted up.
    
    I can't view the boot-up sequence because iocConsole is also no longer 
    working for either CPU:
    
    [softegr at lclsapp1 iocCommon]$ iocConsole lcls-llrfcpu01
      : ssh -x -t -l laci lclsapp2.acc.jlab.org bash -l -c " pyiocscreen.py -t HIOC lcls-llrfcpu01 lclsts1 2001 "
    Read from socket failed: Connection reset by peer
    [softegr at lclsapp1 iocCommon]$ iocConsole lcls-llrfcpu02
      : ssh -x -t -l laci lclsapp2.acc.jlab.org bash -l -c " pyiocscreen.py -t HIOC lcls-llrfcpu02 lclsts1 2002 "
    Read from socket failed: Connection reset by peer
    
    I tried a remote reboot of the terminal server.
    
    I also tried ipmitool (and EPICS ipmi) to remotely restart the CPU.
    
    But still no signs of life.
    
    Perhaps you could take a look at the network and/or locally? We may need a 
    local power-cycle of the CPU and the terminal server. I'm cc'ing Larry 
    Farrish, who may also be able to help with that.
    
    This is not super urgent. When you have a chance during your normal 
    working hours, I'd appreciate any help.
    
    Thanks,
       Sonya
