I completed the install as described below which went well.
I then copied the contents of /boot/efi to /boot/efi_copy using
cd /boot
rsync -acr efi/ efi_copy
I then installed grub2 on sdb
yum install yum install grub2-efi-modules
grub2-install /dev/sdb
everything ran as expected with no errors. The instructions then said to test
the install by powering off and swapping sda and sdb. Instead, I just
unplugged sda.
When I booted the system loaded straight into a grub> prompt.
I powered off and reconnected sda hoping to be able to continue experimenting.
However, even with sda reconnected it just boots into a grub> prompt.
Anyone got suggestions what to do next?
(This server is not live, so can be wiped / experimented on)
