FAS2750 HA create single aggregate

torres91 — Wed, 04 Jun 2025 09:52:41 GMT

Hello all!

Recently I've installed a FAS2750HA with 12x1.8 Tb SAS HDD. We need to take advantage of the maximum available capacity, and we want to only create one data aggregate on node A. As you know Ontap creates 2 root aggregates, one for each node, and the ownership of the 12 disks, divides them 6 and 6 to each node. Root Data partitioned was done on the disks during setup and Ontap doesn't let us change the ownership and shows us the following message:

::> storage disk removeowner 1.0.0

Error: command failed: Failed to remove the owner of disk "1.0.0". Reason: Cannot remove owner of disk "1.0.0" because it is shared.

What steps should we take to change the ownership of the disks to a single node and create one data aggregate with 11 disks ?

Thanks a lot

Hi there!

You need to reassign the partitions, not the drives. Instructions are at https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/How_to_change_ownership_of_disk_or_partition_in_ADP_and_AFF_platforms - note the requirement to "set adv" first.

Hope this helps!

Thanks a lot!.

I've close with the instructions, but my error was in the set adv command, I use priv set admin, and the commands not working. I'll work with your link.

Regards!
