Rebooting Solaris Machine

Thursday, 11 June 2009 in Solaris, UNIX

There is so many command available to reboot server, but which one is which that will gracefully reboot your Solaris server? Just use “reboot” command?

NO NO NO.

That’s not the right thing to do, unless you have no choice. WHY? Because “reboot” doesn’t proceed the shutdown script command, but will reboot as reboot (confuse huh?). init6 is the better choice, and for that, this is my favorite.

shutdown -y -i6 -g 180 "Message to users"

What it will do is, rebooting the server in 3 minutes (180/60) and will give message to the console to any online users.

For lesser hassle, make sure your auto-reboot = true so that you didn’t have to access ALOM to manual input in OK prompt.

root@jebat10 # eeprom |grep auto-boot
auto-boot?=true

It’s always been nice to warn users first and give them ample time to save their works before you’re going to reboot it. And make sure, that you’re rebooting the intended server !!
