Basic Checks
You should perform the following basic checks, whenever you experience
a problem. Perform each of the checks described in this section before
moving on to “Resolving Specific Problems”.
What to Check First
Before suspecting a problem with SNA or SNAplus2, take a few
moments to complete the following checks:
Step 1. Ensure that all communications cables are attached properly to your
machine, switches, and hubs.
Step 2. Check that all modems, switches, and hubs are enabled.
Step 3. Check that the remote systems that you are trying to contact are active.
Step 4. Check that your software and all optional software packages are
installed correctly.
Step 5. Check that all appropriate software fixes or patches have been applied.
Step 6. Consult your system-specific installation documentation for information
about known problems.
Check That the SNA Daemon Is Started
The SNA daemon programs must be started before you can use any SNA
function
The system should start the SNA daemons automatically when
SNAplus2 has been installed successfully, and whenever HP-UX
restarts.
To start the SNA daemons (or to check whether they are running), issue
the snap start command. This command starts the SNA daemons
which include:
• snapdaemon
• snaperrlog
• snapcfgdae (on a server)
