Trouble creating a disk partition slice (EFI)

Hi all,

I am using SPARC Solaris 11.1 with EFI labelled disks.
I am new to ZFS file systems and slightly stuck when trying to create a partition (slice) on one of my LUNs.

EFI labels use sectors and blocks and I am not sure how exactly it works.

From here I can try and create a partition but when I have to enter the Starting Sector, I get confused, as you can see from the below code.

I have tried to understand the sectors and so on, but cannot work out what sector I need to create from.

Any help would be greatly appreciated and/or info on sectors.

Code:

root@odb-grumpy:/# format

       1. c2d2 <NETAPP-LUN-820a-20.00GB>
          /virtual-devices@100/channel-devices@200/disk@2

bootctl

BOOTCTL(1)                                                            bootctl                                                           BOOTCTL(1)

NAME

       bootctl - Control the firmware and boot manager settings

SYNOPSIS

       bootctl [OPTIONS...] status

       bootctl [OPTIONS...] list

       bootctl [OPTIONS...] update

       bootctl [OPTIONS...] install

       bootctl [OPTIONS...] remove

DESCRIPTION

       bootctl checks, updates, installs or removes the boot loader from the current system.

       bootctl status checks and prints the currently installed versions of the boot loader binaries and all current EFI boot variables.

       bootctl list displays all configured boot loader entries.

       bootctl update updates all installed versions of systemd-boot, if the current version is newer than the version installed in the EFI system
       partition. This also includes the EFI default/fallback loader at /EFI/BOOT/BOOT*.EFI. A systemd-boot entry in the EFI boot variables is
       created if there is no current entry. The created entry will be added to the end of the boot order list.

       bootctl install installs systemd-boot into the EFI system partition. A copy of systemd-boot will be stored as the EFI default/fallback
       loader at /EFI/BOOT/BOOT*.EFI. A systemd-boot entry in the EFI boot variables is created and added to the top of the boot order list.

       bootctl remove removes all installed versions of systemd-boot from the EFI system partition, and removes systemd-boot from the EFI boot
       variables.

       If no command is passed, status is implied.

OPTIONS

       The following options are understood:

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

       --path=
           Path to the EFI System Partition (ESP). If not specified, /efi, /boot, and /boot/efi are checked in turn. It is recommended to mount
           the ESP to /boot, if possible.

       -p, --print-path
           This option modifies the behaviour of status. Just print the path to the EFI System Partition (ESP) to standard output and exit.

       --no-variables
           Do not touch the EFI boot variables.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.
