.IX floating-point "reliability tests \(em \fLfparel\fR"
|
|
.LP
|
|
.B fparel
|
|
is a command to execute the Sun
|
|
.SM FPA
|
|
online confidence and
|
|
reliability test program.
|
|
.B fparel
|
|
tests about 90% of the functions of the
|
|
.SM FPA
|
|
board, and tests all
|
|
.SM FPA
|
|
contexts not in use by other processes.
|
|
.B fparel
|
|
runs without disturbing other processes that may be using the
|
|
.SM FPA\s0.
|
|
.B fparel
|
|
can only be run by the super-user.
|
|
.LP
|
|
After a successful pass,
|
|
.B fparel
|
|
writes
|
|
.IP
|
|
.B time, date: Sun
|
|
.SB FPA
|
|
.B
|
|
Passed. The contexts tested are: 0, 1, ... 31
|
|
.LP
|
|
to the file
|
|
.BR /var/adm/diaglog .
|
|
.LP
|
|
If a pass fails,
|
|
.B fparel
|
|
writes
|
|
.IP
|
|
.B time, date: Sun
|
|
.SB FPA
|
|
.B failed
|
|
.LP
|
|
along with the test name and context number that failed,
|
|
to the file
|
|
.BR /var/adm/diaglog .
|
|
.B fparel
|
|
then broadcasts the message
|
|
.IP
|
|
.B time, date: Sun
|
|
.SB FPA
|
|
.B failed, disabled, service required
|
|
.LP
|
|
to all users of the system. Next,
|
|
.B fparel
|
|
causes the kernel to disable the
|
|
.SM FPA\s0.
|
|
Once the
|
|
kernel disables the
|
|
.SM FPA\s0,
|
|
the system must be rebooted to make it
|
|
accessible.
|
|
.LP
|
|
The file
|
|
.B /etc/rc.local
|
|
should contain an entry to cause
|
|
.B fparel
|
|
to be invoked upon reboot to be sure that the
|
|
.SM FPA
|
|
remains
|
|
unaccessible in cases where rebooting doesn't correct the
|
|
problem. See
|
|
.BR rc (8).
|
|
.LP
|
|
The
|
|
.BR crontab (5)
|
|
file for root should contain an entry indicating that
|
|
.BR cron (8)
|
|
is to run
|
|
.B fparel
|
|
daily, such as:
|
|
.IP
|
|
.B 7 2 * * * /usr/etc/fpa/fparel
|
|
.LP
|
|
which causes
|
|
.B fparel
|
|
to run at seven minutes past two, every day.
|
|
See
|
|
.BR cron (8)
|
|
and
