One way is to disable autosupport completely before your maintenance, and re-enable it afterwards.
(And if anything happens to break for-real during your maintenance, you can manually open a Case.)
Davin.

Hi Sebastian,****
thanks, this is a great chart - will keep it bookmarked :)****
I usually do "tell" NetApp when I'm doing maintenance, but since my last OnTap update with serveral TOs and GBs I had 4 cases open and got three calls (which is great support, btw), so I figured noone is actually reading what you tell them via autosupport.doit :)****

Hi Alexander,
You remember correctly, here's what should happen:****
*Type*****
*PSUs*****
*Expected Behavior*****
SAS****
4****
Normal operation. All disks will spin up at the same time.****
3****
Staggered disk spin-up. Six drives per column (four columns) will spin up at a time with 12-second intervals between each column.****
2****
Staggered disk spin-up as above.****
1****
The shelf will still function but with several issues. Any drives that are currently powered up when reduced to one PSU will continue to function. From a cold boot, some drives (undetermined) will not spin up due to a lack of power once a certain number of drives have spun up. This is an unsupported operating condition.****
SATA****
4****
Normal operation. All disks will spin up at the same time.****
3****
Staggered disk spin-up. Six drives per column (four columns) will spin up at a time with 12-second intervals between each column.****
2****
Staggered disk spin-up as above.****
1****
Staggered disk spin-up with one difference. The first three columns, six disks each, will spin up with the normal 12-second interval. The fourth column will spin up five of six disk drives with the sixth drive (bay 23) spinning up 12 seconds later.****
Nevertheless I'd also expect an AutoSupport, since you *do* want a replacement PSU if one actually breaks. You might think about sending NetApp a options autosupport.doit "We're going to do some shelf maintenance" ... ;-)

Hey there,****
we were just re-cabling some of the power cords on our DS4243 shelfs with 4 PSUs and 24x 15k 600GB SAS.****
When I power down one of the 4 available PSUs in the DS4243, I get the following messages in system log and autosupports are generated:****

Why exactly does it think that there are not enough power supplies present if I just shut down one of them? I was under the assumption that a full SAS shelf can work with 2 PSUs and a full SATA shelf can work with 1 PSU without problems. Am I wrong?****
Nothing happend to the filers, no takeover, no errors, etc., but the message in the logs puzzles me.****
Thanks && bye,****
