I am wondering why you ask the question?
It's embedded in the mdadm superblock, and it might be initrd based
auto-activation (metadata 1.x and higher) may fail if the actual host
name and the one in the superblock don't match. There is a way to
update this information at assemble time with mdadm --assemble
But that might be a distraction.
