SunDiag System Exerciser
The SunDiag system exerciser is used to test and exercise system resources and
peripheral equipment. The SunDiag system exerciser verifies that the system is
functioning properly.
The SunDiag system exerciser program is located as follows:
■ /usr/diag/sundiag (Solaris 1.1.x)
■ /opt/SUNWdiag/bin (Solaris 2.x)
If the SunDiag system exerciser is not on the system hard disk or server, it can be
loaded from either a CD or from a network server (for more information, see
theSunDiag User’s Guide).
If SunDiag system exerciser passes, the system is operating properly. If SunDiag
system exerciser fails, error messages are displayed, indicating the part of the system
that failed.
Note – If a SunDiag system exerciser error message is not descriptive enough,
execute the POST for a more descriptive explanation (see Chapter 3.)
