Has been a while since I dealt with those machines - and cannot verify
this here - but if you cannot boot from the disks in the internal bays you
could try the following:
* start the PVE installer in debug mode
* let the installer run (exit the first 2 debug shells, and install
  regularly)
* after the installation is done you get another debug shell
* there re-import the zfs rpool, bind mount what's necessary and chroot
  into the new system - see [0] for steps.
* inside format and init the sd-cards (if you want you can also create
  partitions on them - assuming the sd-card presents itself to the OS as
  /dev/sdX run:
** proxmox-boot-tool format /dev/sdX
** proxmox-boot-tool init /dev/sdX
* exit the chroot, umount, export rpool
* try booting from the sd-card

but this is just from memory - have not tried this and am not sure if it
will work smoothly.

Good luck,
stoiko
