It's probably got some LEDs on the disk tray that's gone bad. Look on the back of the disk shelf. I haven't touched a 630 for quite a while, but it used the same old SCSI shelves as the F500 series, or even the old F300 series possibly. All the fans were on the back of the shelves.

It mostly just forces the OS to ignore the EMU (or lack of one) and just boot the system. It's a failsafe way to keep you from losing more than just a disk in a system. At least thats the impression I get from the doc you provided.
The writeup looks really good, so once you get a replacement, you should be all set to go with another small downtime window.
One of the used NetApp places should be able to get you a replacement shelf or EMU without too much problem.
