System unavailable error when testing Service Director
ENV: AIX 4.1.4, 9076 SP
.PROBLEM: Caller is getting a 'System Unavailable' when running
the "Test Communications Path" option in the Utilities
menu of Service Director.
.ACTION TAKEN: Caller is using an IBM 7852-010 modem. He's tried
dialing out from both a reporting client and a
forwarding server, with the same results.
. Change the modem initialization string to turn error
control ON, responses OFF, and echo OFF. Here are the
relevant AT commands:
. E0 - turn off echo
E1 - turn on echo
Q0 - turn responses on
Q1 - turn responses off
&Q5 - turn on error control
&Q6 - turn off error control
&V - dump the modem's current profile.
. Had customer use the "cu" program to re-initialize the
\# cu -ml tty2
. Values have changed.
~.\ to exit the cu session.
. \# smitty servdir_exec
Test Communications Path
The "system unavailable" error still shows up.
. The tty configuration has been checked,
. Went back into "cu" to view the modem settings, and the
&Q6 is back!
. \# smitty servdir_reg
Build/Update List of Machines for registration
override default configuration.
. There is a modem configuration file defined. We removed
the modem configuration file name, and saved the
machine's data, selecting NOT to override the default
configuration data. We saved the changes (again) and
exited Service Director.
. \# cu -ml tty2
. Next, we refreshed Service Director's "callhome"
process (the Service Director daemon) by killing the
process (a new one should be spawned immediately).
. Caller then ran the test communications path from
a client machine and it is working now. With the
modem configuration file in the machine list, the
modem was reconfigured by Service Director each
time it was invoked.
.ACTION PLAN: Close this call.
