4.3 Troubleshooting the System Using
Diagnostic Software
Software packages, such as Sun VTS, allow you to run diagnostic tests on your
system. SunVTS is a validation test suite that is provided as a supplement to the
Solaris operating environment. The individual tests can stress a device, system, or
resource so as to detect and pinpoint hardware and software failures and to provide
users with informational messages for resolving problems. SunVTS runs at the
operating system level.
The following tests are useful when troubleshooting a Netra CT server:
■ alarm2test
—is part of SunVTS, but it is used to test the alarm card installed in
the Netra CT server by invoking the
alarmdiag
test on the alarm card.
alarm2test
runs at the operating system level.
■ obdiag
—is similar to the
alarm2test
, in that it invokes the
alarmdiag
test on
the alarm card; however,
obdiag
is run from the firmware level, not the
operating system level.
■
Apost
—is part of the embedded firmware image on the alarm card. It runs a
basic test on the alarm card to verify that the alarm card is operating properly
before bringing up Chorus on the alarm card.
A new utility called
diagconf
, which is part of the embedded firmware image on
the alarm card, is now available. You can use
diagconf
to set or display the
configuration settings for
Apost
, allowing you to make the tests run on the alarm
card more or less thoroughly before the embedded firmware is brought up on the
alarm card.
To display the values currently set for
Apost
, access the alarm card command line
interface (CLI) and enter the following command:
hostname
cli> diagconf -d
