Which is the one we expect. /dev/md127p1 is the first partition of
/dev/md127.

Names of RAID devices are built at boot time. It depends on
/etc/mdadm.conf which should be part of the initramfs. Otherwise,
consider the name random.

I don't understand why this blank screen. Or do you mean a black screen?

It should work. Linux software RAID is assembled once the kernel is up
and running. Before, the system boot as usual on a single disk. Though,
I'm not sure how mdadm will handle the disk change behind his back.
Once the installed system is bootable, I suggest you to try to reinstall
grub. This will be required at some point in time in the future to
update it either way.
