Shane AO  

Problem: ShaneAO Software Crash

Manifestation:

• ShaneAO software unresponsive.
• May be accompanied by following report:

   
     <woofer_client.woofer_thread.stop> stopping woofer thread 
     <woofer_client.woofer_thread.stop> waiting for thread to terminate 
     memspower.write("disable",wait=False) 
     <woofer_client.woofer_thread.run> confirmed - woofer thread stopped 
     Segmentation fault (core dumped) 
     

Solution/Recovery:

• ping real.ucolick.org — Verify communication with real-time controller.
• The following requires passwords for both root and gavel. Ensure 2 terminal windows running on real.ucolick.org:
  1. root@real.ucolick.org > tail -f /var/log/messages — Inspect message log.
  2. gavel@real.ucolick.org > shaneao — Re-start ShaneAO software.
• If repeated re-trys are unsuccessful, it may be necessary to reboot the real-time controller:

  root@real.ucolick.org > reboot

• Following successful response to shaneao command, execute the following commands to achieve a standard configuration:

   
     >>> load(scripts) 
      
     >>> camstart() 
      
     >>> ttcamstart() 
     

  >>> mode('16xLGS') or >>> mode('8xLGS')

  >>> init(16) or >>> init(16)

   
     >>> woof('on') 
      
     >>> mems('on') 
      
     >>> ngs() 
      
     >>> offload('on') 
      
     >>> cent(binquad) 
     

  >>> refcent(data/'hs-20XX-XX-XX-BINQUAD_16xLGS_onSky.fits') or >>> refcent(data/'hs-20XX-XX-XX-BINQUAD_8xLGS_onSky.fits')

   
     >>> rate(500) 
      
     >>> rs() 
      
     >>> dark() 
      
     >>> ttrate(500) 
      
     >>> trs() 
      
     >>> ttdark() 
      
     >>> bleed('woofer',0.995)
