How did you do it?
Please share with us how you did it. I have exactly the same problem -- trying to boot AIX from a metro-mirrored rootvg disk. When I try the boot, it stops on at LED 555. I suspect the problem is that the rootvg disk on the copy has a different LUN serial number than the one recorded in the ODM. I've found this serial number in several places and am considering zapping it to the new value. It's safe enough to play with the copy -- I can always resync it from the original if I toast it.
I have set dyntrk=yes on fscsi device, but that did not help.
AIX Support told me that it is not supported to boot from a copied LUN; but if you've found a way, I don't care. I have a lot of systems to move from one SVC to another, and backup/restore will be way too slow and take too much downtime.
Windows and Linux systems do not seem to care--as long as all the bits are where they are supposed to be, they are happy.

Hi All,
I have mirrored SAN volume on my B80 rootvg. Can I just remove the mirror and "Remove a P V from a V G" and it will be a diskless AIX?
Is that going to boot on SAN rootvg volume?
Thanks in advance,

LEARN ABOUT FREEBSD
boot.config
BOOT.CONFIG(5) BSD File Formats Manual BOOT.CONFIG(5)
NAME
boot.config -- Configuration file for the boot blocks
DESCRIPTION
The boot.config file contains options for the FreeBSD boot block code.
When the FreeBSD boot loader runs, it searches the ``a'' slice of the boot partition for a boot.config file (as a result, slices which are
missing an ``a'' partition require user intervention during the boot process). If the boot.config file is found, its contents are used as
the default configuration options for the boot block code and are echoed to the system console.
A valid format of this file is to put BIOS drive number, a controller type, a unit number, a partition, a kernel file name, and any other
valid boot(8) option on a single line, as it is done at the ``boot:'' prompt.
The options related to the boot image selection described below and all the other options available for boot.config are documented in detail
in the boot(8) manual page.
FILES
/boot.config parameters for the boot blocks (optional)
EXAMPLES
The command:
# echo "-P" > /boot.config
will activate the serial console of FreeBSD.
The command:
# echo "1:ad(1,a)/boot/loader" > /boot.config
will instruct the second stage of boot(8) on the first disk to boot with the third boot(8) stage from the second disk.
The command:
# echo "1:ad(1,a)/boot/loader -P" > /boot.config
will do both of the above.
