UNIX Solaris

Hello All

I just want to know how to Shut Down the Solaris Machines( Servers ) for Maintainance and then Start Up the Machines ( Servers ) .

I think I will have to Log In as root to do that .

Also how do i Check if all the services running on that server before shut down are running again after the Start Up

What kind of maintenace do you do?

patching (single user mode)

  • go to the console and boot in single user mode (init 1, shutdown -y -g0 -i1)
  • after the installation do a reboot or a shutdown -y -g0 -i6

or change faulty parts

  • go to the console and bring the box down with init 0 (5) or shutdown -y -g0 -i0 (5)
  • just switch it on
