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].

[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
-
[IS] Check outdir to make sure no one is taking data:
cdata
ls –altr
show –terse –s alad outdir
-
[IS] Stop NIRC2 daemons to prevent the transputers from hanging:
nirc2 stop daemons
-
[CS] Bring up a console line:
telnet k2consoles 2008
hit return and confirm waikoko console login: prompt.
-
[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)!]

console telnet session.

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
- Startup Quicklook and Status GUIs:
nirc2 start quicklook
nirc2 start statusd
-
Create a new data directory:
newdir
-
Save a test image on disk:
tint 1
coadd 1
shutter close

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.

[IS] Quit out of GUI tools and email folks that reboot is
complete.
