Hi NetApp Community,
I've just setup a new fresh config into my FAS2552 in Switchless clustered DATA ONTAP mode and i need explanations about disks and aggregates.
I have a 24 disk shelves and 2 controllers, at the beginning of my configuration, I set 3 disks as root volume, so I think this is why they don't have Container name when I type disk show :
1.0.19 836.9GB 0 19 SAS shared root_aggr_node_01 Node_01 1.0.20 836.9GB 0 20 SAS shared - Node_02 Usable Disk Container Container Disk Size Shelf Bay Type Type Name Owner ---------------- ---------- ----- --- ------- ----------- --------- -------- 1.0.21 836.9GB 0 21 SAS shared root_aggr_node_01 Node_01 1.0.22 836.9GB 0 22 SAS shared - Node_02 1.0.23 836.9GB 0 23 SAS shared - Node_01 24 entries were displayed.
Now i only have the 2 root aggregates and I need to create 2 news, one for each controller.
So i'm going to create one from onCommand System Manager, then I see there's 14 disks for one controller and 10 for the other :
So my question is : how the system attribute disks to Node ?and why I can't have something like : 12 disks for one controller and 12 on the other ?

From your output I see that your disks show as a container type of shared. It looks like then you are using 8.3.x that supports root-data partiioning that might describe some of what you are seeing. Take a look here: https://library.netapp.com/ecmdocs/ECMP12458210/html/GUID-52897F29-1442-47CA-BD02-53F435D9FCC7.html. It shows a pretty good graphic of the layout of disks with this type of assignment. Can you review that against your configuration?

Thank you for the link. I understand the process but I don't know what to do for changing that.
In my actual configuration I've got 2 controller, so 2 root aggregates (so one aggregate per controller), their size can't be modified and it's auto-managed by the system itself isn't it ?
All my disks have "shared" container type cause it run version 8.3P1, moreover they all got Node_01 or Node_02 as owner.
Their container name are root_aggr_node_01 or root_aggr_node_02 but when I type "disk show" , 5 of 24 disks haven't a container name.
Furthermore, I think I confused notions like spare,root ...
Do you know what I mean ?
Really thank you for reading and answering.
