So just has to create ggate provider (with ggatec), gmirror(8) will
handle the rest automatically.

You don't need -h and you don't need to use gmirror in your script at
all.

There is currently no rc.d/ scripts for ggate, but you can check out
freebsd-geom@ archives, I think someone post such scripts some time ago,
but I haven't had time to look into it yet.
