Troubleshooting guide

III.Nightly Startup Tasks
A. FLAMINGOS Setup
We recommend that you carry out the following procedures prior to each night's observing.
1. Restart all daemons, temperature logging and temperature plotting windows. This now seems to be largely
unnecessary. If the system is up and running in the afternoon, continue to use it. The daemons should
all be Quit (not Closed, as this just minimizes them), and initflam.pl immediately re-run, in order to restart the
daemons.
2. Fill Both Dewars. At the 4-m the telescope operator should be in charge of filling the dewars with liquid
nitrogen. Both the Camera dewar (the big one on the bottom) and the MOS dewar (the one on the top) need
to be filled with liquid nitrogen at the start of every night before you observe, and the MOS dewar also needs
to be filled at the end of every night.
3. Create a data directory for the night on flamingos1a.
From any flamingos1a window:
4mguest@flmn-4m-1a{1} cd /data/4mguest/
• Create a directory on flamingos1a with the UT date in the format YYYYMMDD (or whatever
designation you prefer), e.g.,:
4mguest@flmn-4m-1a{1} mkdir 2003sep15ut
• Verify that flamingos1a has enough disk space available. Typing df -h on flamingos1a shows the
following output:
Filesystem Size Used Avail Use% Mounted on
/dev/dsk/c1t0d0s0 9.3G 1.3G 7.9G 15% /
/dev/dsk/c1t0d0s1 9.3G 2.7G 6.5G 29% /usr
/dev/dsk/c1t0d0p0:boot 11M 1.7M 9.0M 16% /boot
swap 951M 12K 951M 1% /var/run
swap 961M 9.2M 951M 1% /tmp
/dev/dsk/c1t1d0s0 68G 29G 38G 44% /data
/dev/dsk/c1t0d0s2 16G 2.5G 13G 17% /home
In this example the data disk on flamingos1a, /data, is 44% full, and had 38 GB of available space.
For imaging you should ensure that there is at least 10 GB of space available; for spectroscopy you
should have ~5 GB of space. However, note that the image acquisition scripts will complain on each
and every image if the disk space is is ≥ 93% full, and will refuse to take any more data if the disk is ≥
97% full.
NOTE: We now mirror the data on flamingos1a to mayall-2 or mayall-3 instead of using the old Autocopy
script. This is more convenient and is significantly more convenient for transferring the data to DVD or a USB
drive.
