Rebooting an E4500

Post #1 of 6 (2267 views)

I have an E4500 that boots just fine from powerup but when I try to do a
'shutdown -r now' or 'reboot' from Gentoo it always tries to boot from
the network. I have boot-command and boot-device set properly in
openboot but the 'reboot' seems to ignore this. I have tried the "fix"
on the ultralinux.org site (http://www.ultralinux.org/faq.html#q_5_39)
for this but my openboot PROM doesn't have a sunmon-compat variable. I
want to implement a scheduled reboot to get around the problem of the
system hanging and only responding to pings, which was discusses earlier
this week on this list.

Do you have "diag-switch?" set to true or false? If it's set to true,
then it'll boot from "diag-device" rather than "boot-device". either turn
diag-switch? to false, or set the diag-device to what you want it to boot
from.

'diag-switch?" is set to false

Is the physical switch or key set to "On" rather than "Diag"? The
physical switch will override the OPENPROM setting. You may need to
decode the icons. I think Diag mode is an open-ended wrench.

The switch is in the "On" position. Same thing happens in the "Locked"
position. The sequence is "Off", "On", "Diag", "Locked".

Even though I had 'diag-switch?" set to false I went ahead and changed
'diag-device' to be the same as 'boot-device' and now a reboot works as
expected (or at least as I wanted). So the "fix" is to set both
'boot-device' and 'diag-device' to the same device or device alias.

Thank you to everyone for helping.
