Script debugging tips

The following tips may be useful when debugging SCO OpenServer 5 MDI installation and configuration scripts:

• Use the script command to debug shell scripts such as the lkcfg script:

  1. Put the set -x in the top of the script that you are debugging.

  2. Run the script command.

  3. Run the netconfig command and add your driver; this will execute your lkcfg script as part of driver configuration.

  4. Type <Ctrl>D and look at the typescript file. This file should contain all the output from the script that contains the set -x line as well as all the other information sent to or from the screen.

• Examine the ``sysdb'' records in the /var/`llipathmap`/sysdb directory. These are stanza format files that contain configurable options selected by the user when running netconfig, including the adapter's KEY and all options with TYPE=swconfig and TYPE=link-kit in the AOF.

• Verify entries in /etc/conf/sdevice.d/<driver_name> by comparing them after the lkcfg script executes with entries in the driver's sysdb record. lkcfg is called by netconfig init or reconf.

• Examine the contents of the /etc/conf/cf.d/mdevice and /etc/conf/pack.d/<driver_name>/space.h files.
