/boot/efi on RAID-1 (mdraid)

[Sam Varshavchik <mrsam@xxxxxxxxxxxxxxx>]

I installed F30 on a replacement server with two HDDs. My existing hardware  
earned its well-deserved retirement. My replacement hardware is the first  
server hardware I'm using that uses EFI and the GPT.

I configured all my partitions with mdraid, including /boot/efi:

/dev/md124 on /boot/efi type vfat (rw,relatime,fmask=0077,dmask=0077,
codepage=437,iocharset=ascii,shortname=winnt,errors=remount-ro)

/dev/md124:
          Version : 1.0
    Creation Time : Sat Oct 26 20:49:42 2019
       Raid Level : raid1
       Array Size : 1049536 (1024.94 MiB 1074.72 MB)
    Used Dev Size : 1049536 (1024.94 MiB 1074.72 MB)

[ . . . ]

   Number   Major   Minor   RaidDevice State
      0       8        4        0      active sync   /dev/sda4
      1       8       20        1      active sync   /dev/sdb4

I want to make sure that in the event one of the disks fail I'll be able to  
boot off the other one. Are any additional steps needed for this, beyond the  
ones that were done by F30's installer?

With BIOS I knew I needed to run grub-install to manually install grub on  
/dev/sdb in addition to /dev/sda; do I need to do anything analogous to  
that, with EFI?
