	The default root pool (rpool) is a single disk immediately after install (eg ~~c3t0d0~~). ~~Add~~ a second disk (~~c3t1d0~~) to make a mirror and ensure it's bootable (see [https://docs.oracle.com/en/operating-systems/solaris/oracle-solaris/11.4/manage-zfs/managing-zfs-root-pool1.html here]):		=== Create a rpool mirror ===
	zpool attach rpool ~~c3t0d0 c3t1d0~~
			Assume here during install an EFI format disk was selected. The default root pool (rpool) is a single disk immediately after install (eg c3t0d0s0). We would like to add a second disk (c3t1d0s0) to make a mirror and ensure it's bootable (see [https://docs.oracle.com/en/operating-systems/solaris/oracle-solaris/11.4/manage-zfs/managing-zfs-root-pool1.html here]).

			The second disk partition scheme must me configured to match the first. Observe the structure:
			format -e
			-> select disk 0 -> partition -> print -> quit

			Expect small boot partition (0), main usr partition (1) and small reserved (8).

			format -e
			-> select disk 1 -> partition -> 0 -> enter label -> enter flags -> enter start sector -> enter end sector (with e suffix) -> label -> quit

			Add to rpool
			zpool attach rpool c3t0d0s0 c3t1d0s0

	Then, monitor "zpool status rpool" output until "re-silvering" is complete.		Then, monitor "zpool status rpool" output until "re-silvering" is complete.

			Installation is performed on a single disk; complex ZFS configurations need to be configured afterwards. The installer gives options:
			1) Use the entire disk
			* This creates a VTOC (SMI) label inside an MBR-style disk.
			* It is the old Solaris x86 layout.
			* The installer writes a Solaris2 fdisk partition covering the whole disk
			* Inside that, Solaris creates VTOC slices (s0, s1, etc.)
			* Boot method is legacy BIOS + GRUB
			* Maximum usable disk size is 2 TB
			* This is the layout used by older Solaris releases (10, early 11.x)
			* This option exists mainly for compatibility with older hardware or older Solaris setups.

			2) Use a GPT partition on the disk
			* This creates a GPT-labeled disk with an EFI System Partition (ESP).
			* It is the modern Solaris layout.
			* Uses EFI/GPT partitioning
			* Boot method is UEFI + GRUB2
			* Supports disks larger than 2 TB
			* Cleaner layout:
			**EFI System Partition
			** rpool partition
			** Required for modern hardware and recommended for new installs
			** This is the layout Oracle expects for Solaris 11.4 going forward.
