Now where's the fun in that??? ;-) You should be able to perform all your filer hardware maintenance with a hunting knife, some chewing gum, and two feet of piano wire. :)

What!! No duct tape???? I can't work without duct tape! I would lose my honorary MacGuyver badge and then they'd have to send me through the stargate.

Nope, sorry... duct tape makes things *too* easy. :) You've got a piece of chewing gum (flavour is up to you) and piano wire. That should approximate duct tape in several usage scenarios. ;-)
For my griping - everything BUT the motherboard is designed for easy swap-out. Why can't they make the motherboard just as easy? Let's face it, if best-case is 15 minutes on a mission critical system, that's not right. ever taken apart a Sparc or HPUX system? They're designed to be modular so it's just pop-out, pop-in, back in service. A design idea Netapp should follow...
But otherwise, sounds like fun ;)

Actually, it is pretty easy. Two things extend the swap out time (by about a factor of two):
o the hexagonal bolts holding the SCSI connector, console, diagnostic, and onboard FCAL connector. I don't see a way around not having these bolted to the chassis; you don't want these things flapping in the breeze, since they are connector to external cables, which inevitably get pulled at or tripped over sometime.
o the 10-12 screws holding the motherboard to the chassis. Again, you don't want the motherboard flapping around inside, either. A dozen screws sounds a bit excessive though.
If all these screws were absent, all you have to deal with are the screws holding the PCI cards in place.

I have always had bad luck fitting SBus cards in Suns; I can never get them wedged into the external slots just right. And, those dinky little screws on the back are hard to handle even without having fat fingers.
If your filer is that mission critical, NetApp will probably advise you to cluster it if even 15 minutes is not acceptable.
Until next time...

It is, and you certainly don't need that many for your filer to run fine. You can screw in half as many if you like. But remember, Netapp has to *ship* these things, and the more screws you have, the less possibility of damage.

Some of those SBus cards are impossible, particularly when they are 3rd party and don't *quite* fit exactly. Screws? I just skip 'em.

The simplest thing to do would be to ship replacement motherboards pre-installed on the system tray. Now that the CableBundleOfDeath is replaced by that nice little edge connector, it'd just be an issue of pulling the whole tray out, replacing the easy stuff (memory, pci cards) and slide the new tray in. Smooooth.
In re: olympics; I have to disagree w/ Todd's rules requiring no pre-disassembly -- that way knowledge is rewarded as well. In the 5 minutes prior to the bell, you're allowed onto the filer's console to determine things like VIF interfaces to start disconecting now, idle tape drives that can go, etc..
