Check: During installation

What to check first

DAS does not start at all:

• are there warnings or errors? Check /home/adcp/log for *.err and *.warn files
• any mesage in *.warn or *.err will have more information in the matching *.log file

DAS does not start logging:

• are the serial ports and baud rates all correct? Check

  • /home/adcp/config/sensor_cfg.py

• Check your serial messages: they should all have checksums, they should be coming in at about 1Hz. If it is more frequent than that you can subsample the input; BEWARE: Only subsample if data are more frequent than 1Hz, and subsample by a prime number to void aliasing of data streams.

• paths and permissions:

  • do the appropriate serial ports exist?
  • do the relevant serial ports all have a+rw permission?
  • does user adcp have +rw permission in /var/lock?
  • is there a directory /home/data that user adcp can write to?

• are there extra files in /home/adcp/flags??

  1. stop logging, end cruise, kill gui
  2. remove all files from /home/adcp/flags
  3. kill all processes with “matlab”, “DAS”, or “ser_” in them (but not the license manager)
  4. start gui, try again

Logging starts but there are no plots:

• Is the matlab license manager running?
• Are there files in /var/tmp with the matlab name (“TMW”) that are owned by root (or someone other than user “adcp”)?
• There should be one entry from this query:

ps -ef | grep MLM | grep -v grep
