NIRC2 Host Reboot

The procedure to reboot the NIRC2 host waikoko is a coordinated effort between Computer Support staff and the Istrument Scientist. The following lines describe the reboot procedure step by step. The steps peformed by the Instrument Scientist are tagged as [IS] and the steps to be performed by the Computer Support staff are tagged as [CS].

  1. [IS] Send an e-mail to computersupport to help with the reboot.
  2. [IS] Send mail to nirc2_info and aouser group with 5 minute warning.
  3. [IS] Log into waikoko as nirc2eng.
  4. [IS] Excecute snaptemps and copy the temporary file down to a dated file at HQ:
    	cp –p /tmp/s.out /net/filer2/vol/home/nirc2eng/snaptemps/snaptemps.YYYY-MM-DD
  5. [IS] Check outdir to make sure no one is taking data:
    	cdata
    	ls –altr 
    	show –terse –s alad outdir
  6. [IS] Stop NIRC2 daemons to prevent the transputers from hanging:
    	nirc2 stop daemons
  7. [CS] Bring up a console line:
    	telnet k2consoles 2008
    hit return and confirm waikoko console login: prompt.
  8. [CS] Login as root:
    	init 1 [wait for it to do its thing; you will have to log  back in]
            sync; sync ; reboot  [make sure you type this exactly (execute
            on one line)!]
  9. [CS] Once it is up in multi-user mode log out of the waikoko console telnet session.
  10. [IS] Log in as nirc2eng at waikoko:
    1. Start NIRC2 daemons:
      	    nirc2 start daemons
      Answer ‘y’ to questions. It is normal for it to retry 3x for transputer comms.
      	    ct [verify 3 alad_server_bin tasks are running]
      	    s coadds [to test]
      	    nirc2 start pmr
    2. Take a snapshot of the temperatues and save file in HQ:
      	    snaptemps
                  cp –p /tmp/s.out /net/filer2/vol/home/nirc2eng/snaptemps/snaptemps.YYYY-MM-DD-postboot
    3. Startup Quicklook and Status GUIs:
      	    nirc2 start quicklook
      	    nirc2 start statusd
    4. Create a new data directory:
      	    newdir
    5. Save a test image on disk:
      	    tint 1
      	    coadd 1
      	    shutter close
      	    goi
      You should see an image appear in the quicklook display. The first image typically shows -32,000 counts. Take another image. The image should have ∼ -100 → 100 counts.
  11. [IS] Quit out of GUI tools and email folks that reboot is complete.
