In the immortal words of George Kahler (george@YorkU.CA):
Could someone please explain what happens when you loose a single power supply in a shelf?
Is the filer smart (dumb) enough to halt? Do I get 'double disk error' and loose the filesystem?
There is a discussion going on here as to what happens in a hardware RAID configuration vs a NetApp filer when a power supply fails.
The thought is that if I have only one power supply in a shelf and it fails (failing 7 disks) it is like having multiple disks fail and therefore you loose the filesystem.
On a filer with dual shelf power supplies, it registers a shelf fault, screams loudly, and moves on.
I've never used a filer with single shelf power supplies, but I have, uh, accidentally powered off a shelf on a running F630 once. (D'oh!) The filer pretty much immediately halted, but came back up with not too much difficulty.
