AFF Partitioning in 9.1

I had such good luck with my last post. I'm going for 2 for 2. 😄

 

Current Ontap 9 Documentation states that in an AFF, you should assign disks 0-11 to node 1 and 12-24 to node 2.

However, I see that we now have 2 data partitions:

 

xxxxx::*> disk partition show 9.0.1.*

                          Usable  Container     Container

Partition                 Size    Type          Name              Owner

------------------------- ------- ------------- ----------------- -----------------

9.0.1.P1                   1.72TB spare         Pool0             xxxxx

9.0.1.P2                   1.72TB spare         Pool0             xxxxx

9.0.1.P3                  59.72GB aggregate     /xxxrootxxx/plex0/rg0

                                                                  xxxxx

 

 

Should the new best practice be to assign all P1's to node 1 and all P2's to node 2?

 

 

Looking for some guidance.

 

Thanks in advance!

That is correct.

 

Root-Data-Data (R-D2) partitioning divides SSDs into 2 large data partitions and 1 small root partition. One data partition per SSD is assigned to each node in the HA pair.

 

Only one SSD is required for hot spare partitions. This results in more usable capacity.

 

You then create an aggregate with a raid size of 23 (21 data + 2 parity) on each node.

 

I hope this helps!

Hi midi,

Just put them into the empty slots in the two DS2246s attached and they will be automatically partitioned, then it's a matter of assigning the data partitions to existing aggregates using either the GUI or CL
Hope this helps!
