FAS2552 with DS4243 Shelf - ADP


Hello Everyone 


I just converted my FAS2552 to CDOT and in the process of upgrading to 8.3. I would also like to do ADP to efficiently use the SAS drives on the internal shelf. I will be using this KB to do the ADP   


My question is, what will happen to my external disk shelf disks, will it be partioned too? Or is ADP only for the internal shelf. Of course i dont want my external disk shelf disks to be partioned because it will be a waste of space.





Hi Anthony,

the key sentence in the KB article is

"For entry-level platform models, only internal disks are partitioned."

The FAS2552 system is classed as an entry-level platform.

I assume that internal disks are the disks in shelf 0.


If you subsequently add disks to a raid group that contains partioned disks, ONTAP will partition the new disks.

Other than that, there is no way that I'm aware of that you cam manually partition disks.


Hope this helps,



ADP is only for internal disks and SSD. But it makes sense to disconnect shelves while performing initialization just in case.
