Hi,
I've recently written a Netapp security policy for 7-mode Ontap. I used the TRs for reference:
Data ONTAP Security Guidance - TR-3950 (November 2011)
PCI-DSS Version 2.0 and Data ONTAP 8.1 TR-3996 (August 2012)
Both of these are fairly old and not specific to cDOT.
I've seen TR-4191 but that is specific to Windows File services:
TR-4191 - Best Practices Guide for Clustered Data ONTAP 8.2.x Windows File Services
Does anyone know of any best practise documents for cDOT whether Netapp or otherwise?
Thanks Martin

Hey Martin,
I¹ve recently requested something similar from NetApp actually, I¹m waiting on them getting back to me. I was particularly interested in FSA/PCI stuff as it¹s for a financial house..
I¹ll let you know when I get something back from them..
Cheers Ed

Hi, We are migrating all data from an old fas2040 to a newer netapp in a different location. The fas2040 has several DS14 shelves, and one ds4243 shelf.
I wonder if I can just turn off disk shelves as the data is migrated? Normally I'd just let the disks spin till I had everything safely moved, and the disk sanitized. But we lost AC in this room, and warm weather approaches. Can I simply unshare, and unmount all volumes on a disk tray, then turn the tray off to reduce heat generation? (later once I know all the data is safe, and snapshots have caught up on the new system, I'd like to turn the shelf back on, delete the aggregates, and sanitize the disks)
Will this work? Or will the 2040 be very unhappy if a shelf is turned off?
Thanks for your help David

*THIS IS NOT SUPPORTED* I have in the past removed shelves from 7-mode and cDOT systems There was no intent to put them back on the same controller. I had no issues, but that does not mean you won't. As removing shelves from a 7-mode system generally result in the possibility of an unstable system, it is a good idea to reboot shortly after. Or better yet, schedule a reboot and remove the shelves at that time.
A Shelf of disks that are not active does not generate very much heat. Only when they are active will the BTUs increase.

Note that the first document states:
Support for shelf hot-remove
Data ONTAP 8.2.1 and later 8.2.x releases support the hot removal of disk shelves—the physical removal of disk shelves that have had the data evacuated—in multipath HA or single-controller-dual-path (multipath) storage systems that are currently up and serving data. You can hot remove one or more SAS or FC disk shelves from anywhere within a stack or loop of disk shelves, or an entire stack or loop of disk shelves.
Which is why I stated that it depends on the OS and configuration. C-

Sorry, I meant what I did was not supported...I was on 8.1...definitely not supported. There was logic put in to allow for the shelf removal as the docs indicate.
Some of that logic also allows the shelf to be reattached....doing so in prior releases can really mess things up which requires a reboot to resolve.

Need to be careful with that on the ds14 shelves. The first two slots are the SES(shelf enclosure Services) slots. No disks means no shelf or disk management. They need to be in the slots to close a circuit to make it work... Failed or not You can make the disks spares and they will generate very little heat. The system does an hourly periodic spare disk health check and that's about it.

Will this work? Or will the 2040 be very unhappy if a shelf is turned off?

Yep, spare disks are not in raid groups.

As soon as you fail the third disk in a raid group, filer panics.

Sorry, I meant what I did was not supported...I was on 8.1...definitely not supported. There was logic put in to allow for the shelf removal as the docs indicate.
Some of that logic also allows the shelf to be reattached....doing so in prior releases can really mess things up which requires a reboot to resolve.

Support for shelf hot-remove
Data ONTAP 8.2.1 and later 8.2.x releases support the hot removal of disk shelves—the physical removal of disk shelves that have had the data evacuated—in multipath HA or single-controller-dual-path (multipath) storage systems that are currently up and serving data. You can hot remove one or more SAS or FC disk shelves from anywhere within a stack or loop of disk shelves, or an entire stack or loop of disk shelves.
Which is why I stated that it depends on the OS and configuration. C-

I had no issues, but that does not mean you won't. As removing shelves from a 7-mode system generally result in the possibility of an unstable system, it is a good idea to reboot shortly after. Or better yet, schedule a reboot and remove the shelves at that time.
A Shelf of disks that are not active does not generate very much heat. Only when they are active will the BTUs increase.

FAS will panic with multidisc failure if disks with active aggregate are suddenly lost and it may panic even if you unplug empty shelf. Also you will need at least aggregate that hosts root volume.
You can briefly shut down filer, unplug shelves with aggregates that are not needed any more, boot filer again.

Hi David,
Online disk shelf removal is only supported from ONTAP 8.2 onwards. Since a FAS2040 is not able to run 8.2, the official answer is that this is an unsupported action.
This being said, I've seen it work on systems with 8.1 and lower on it. And since you are slowly decommissioning the FAS2040, you may decide it's worth the risk of hot-removing some shelves...
In any event, the official procedure requires you to destroy any aggregates on the diskshelves to be removed first, and unown all disks before removing a diskshelf. If you want to remove one shelf at a time, you may require several disk move commands to free up one shelf. Additionally, removing shelves must take into account that FCAL/SAS access to the other shelves must be maintained at all times. This is generally where MPHA comes into play.
Best regards, Filip
