halt, which makes sense, since if the shelf was still powered down, or the loop broken, it would have to repeat the same cycle on reboot.
That's what I thought at first, but I had the notion that the filer reboots on the first try and then halting if it encounters the same error condition (to go with its "let's do a quick reboot and see if that wakes anything up" philosophy). Perhaps not. There was a case I ran across a few years ago where the filer would only try rebooting itself 5 times in a row to clear a problem, and then would give up and halt.
