format can't find a disk

Hello all,

I was hoping to use a spare NAS as a ZFS fileserver and try a few things.

Unfortunately it has a huge raid for data, but a small 1G system disk. As I want to use the kernel CIFS server, I need OpenSolaris, which doesn't install without all the bloated Gnomestuff (oh well)

So I thought about a manual install with the live cd from an installation I will do from a Virtualbox Guest.

Anyway, when I start the installer (on the nas) I can see the 1G drive as too small, but it's there. When I enter format, it says "no disks found"! Yet, using disk /dev/rdsk/c7t0d0p0 it is recognized. Again, with c7t0d0 it says "must use a raw device"

Any suggestions?

format -e did the trick

use format -e and try
EFI and SMI are the two ways to label a disk.
EFI label is usually used for disk with above 2Tb. Otherwise usually SMI is used for labeling the disk.
I don't think there will be any performance difference

The below link gives more information on EFI labels

try using dd command while installation. there is a step during installation when you can exit from the installation console and you have a shell to perform disk maintenance. once you are done with disk managment, you can re-start the installation from the same point where you left it by using install-solaris or a similar script in your $PATH
