OS is installed on first raid and working very fine

Can you reboot the server once?

I have set up hardware raid on a couple of Sun servers running Solaris 10 and found in each case that a reboot was necessary before the OS properly saw the configuration of the raid device. Annoying, but it did work just fine after rebooting.
