Fallback Miniroot

S7-2 solaris 11.3 and S7-2L Solaris 11.4 ( New Servers )

Am confused as to how to boot Solaris 11 in case of DR.
What is the "Fallback Miniroot". None of my new servers will boot off it. (See below )
You can see from the rmmount command below that the device is mounted and I can access it
via the operating system. It does match the version of the operating system.
I was able to attach an external DVD drive with the "text install" DVD and boot off that into the "Shell". So that will be the DR plan for now.
But what is the "Fallback Miniroot" Am I flogging a dead horse trying to boot off it.

Code:

 rmmount -l
/dev/dsk/c2t0d0s2    cdrom,cdrom0,cd,cd0,sr,sr0,Solaris-11_4_5_3_0-Boot-SPARC,/media/Solaris-11_4_5_3_0-Boot-SPARC

Code:

{0} ok boot  fallback-miniroot
Boot device: /pci@300/pci@1/pci@0/pci@2/usb@0/hub@2/storage@1/disk@0  File and args:

mkcd

mkcd(1M)						  System Administration Commands						  mkcd(1M)

NAME

       mkcd - create bootable Solaris ISO image

SYNOPSIS

       /usr/bin/mkcd -v [-l label] media-root iso

DESCRIPTION

       The  mkcd  utility takes media-root (the root of an on-disk Solaris install media) as input and creates a bootable Solaris ISO image in the
       file iso, using mkisofs(8). The file can then be burned onto a CD/DVD with utilities such as cdrw(1) or	cdrecord(1).  (Neither	mkisofs(8)
       nor cdrecord(1) are SunOS man pages.)

       Caution -

	 The directory tree media-root must contain the file boot/grub/stage2_eltorito, which will be written to the media boot sectors. This file
	 will be modified with some boot information, thus it must be writable. If necessary, first save a copy prior to running this utility.

OPTIONS

       The following options are supported:

       -l label

	   Sets label as the label/volume name of the ISO image.

       -v

	   Verbose. Multiple -v options increase verbosity.

OPERANDS

       The following operands are supported:

       media-root

	   Top-level directory of an on-disk Solaris install media.

       iso

	   Name of the output file which will contain the resulting ISO image.

EXAMPLES

       Example 1 Creating an ISO Image and Burning a CD/DVD

       The following commands create an ISO image from the content of s10u1 and burn the image to a CD/DVD.

	 # /usr/bin/mkcd s10u1 s10u1.iso
	 # /usr/bin/cdrw -i s10u1.iso
