Anyone ever had this alarm? When I dig further I see SCSI faults. I am assuming a reboot will fix, but I hate turning these things off. Thanks in advance.

Thew winchester alarm is saying there's a problem with the Plane A Hard Drive.
Reloading Plane A may clear the alarm. If not, you could try to reformat the drive, or replace it with another.
Of course you'll want a current backup before doing anything else!

If Plane B is active, then you have a working copy of the load on Plane B. You can make a copy, if you want, but you can try a reload and see if the error clears. If it doesn't clear, you probably have a bad hard drive. Those drives are always running and it's a wonder they don't fail more often.
