DISQUS

Sync is no longer necessary in any modern version of Unix (Solaris and Linux included). If you're a system administrator, you should learn proper use of the init command, which allows you to change runlevels. Here are a few different uses of init:

# init 6 - reboots the system
# init 5 - halts the system (turns power off)
# init 0 - sends you to runlevel 0, which is the "ok" prompt (OpenBoot PROM)
# init 1 - sends you to single user mode, useful for installing patches.

umm.. but I believe

shutdown -h 5 -g 60 -y

That will shut it down cleanly and power it off.

"shutdown" includes sync and all that graceful fun stuff.

Hi anybody,
can't reboot my E450, sure i'm root . But any of these init 6, reboot, or halt commands returns me (after some seconds) to the shell prompt.

any idea? thx. Troy

Try this:

/sbin/uadmin 2 0

That will shutdown the node without the execution of the init kill scripts...

btw what version of solaris / kernal patch level are your using?

Hopefully you've sorted this by now, but use shutdown -i6 -g0 -y to reboot if none of the others work, though I can't think why they shouldn't.
