Okay I have the damaged drive fixed and running. It looks like it
failed april 6th. So everything has been running on the other drive.
But I can't get the other drive to boot.
How can if fix it so it will boot? When I hooked them together after
fixing the primary drive it still wouldn't boot. If I unplug the mirror
drive that won't boot It will boot from the drive I fixed.
So I need to get the secondary mirror that is current to boot and then
mirror it to the fixed drive (or soon to have replacement drive)
I am desperate to get this going.
