Troubleshooting guide

III.Nightly Startup Tasks
A. FLAMINGOS Setup
We recommend that you complete the following list prior to each night's observing.
1. Restart all daemons, temperature logging and temperature plotting windows. Please see the notes at the end
of the previous section. 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 main 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 can 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 and on nutmeg and start the autocopy script.
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
Create a directory on nutmeg with the exact same name, and make it world writable:
4mguest@flmn-4m-1a{1} pushd /net/nutmeg/md4/4meter/Flamingos
4mguest@flmn-4m-1a{1} mkdir 2003sep15ut
4mguest@flmn-4m-1a{1} chmod a+w 2003sep15ut
4mguest@flmn-4m-1a{1} popd
Verify that flamingos1a and nutmeg have 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
nutmeg:/md4 100G 30G 66G 31% /net/nutmeg/md4
In this example the data disk on flamingos1a, /data, is 44% full, and had 38 GB of available space;
the data disk on nutmeg, /net/nutmeg/md4, is 31% full, and has 66 GB of available space. For
imaging you should ensure that there is at least ≥10 GB of space available; for spectroscopy you
