Heck, it looks like your mirrors are simply offline. Each paragraph tells you the problem and what you need to do to bring them back on line. In this case, just run the individual metaonline commands as listed.

As to why, per the man page (man metaonline), one good reason would be to run a full backup of the system. In your backup script you'd bring the disks offline, run the backup on the down disks, and then bring them back online. They'd have to resync for your dual mirror system which might take a while depending on sizes.

If there was a problem with the backups, perhaps the disks wouldn't have been brought back online. I'd have to poke around in the scheduled scripts to see if something's bringing them down for some reason.
