Reboot a Solaris system

The process of shutting down a Solaris system is critical. Using the init program to restart a system causes Solaris to perform a sequence of steps to shutdown services gracefully. The reboot command bypasses the runtime control scripts and can compromise data integrity. The sync commands synchronize the filesystem, flushing buffered data to disk.

As superuser:

sync; sync; init 6

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

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.
