Upgrading to a 64-bit aggregate
For storage systems running Data ONTAP 8.1 and later, System Manager enables you to upgrade an existing 32-bit aggregate to a 64-bit aggregate by adding disks to increase their size beyond 16 TB.
Before you begin 
If you want to add disks to the aggregate, you must have completed the following requirements:
•
All the existing disks in the aggregate must be of the same size.
•
You must have sufficient homogeneous spare disks of the same size as the existing disks in the aggregate.
About this task 
You cannot upgrade a SyncMirror aggregate to 64 bit.
Steps 
1.
From the home page, double-click the appropriate storage system.
2.
In the navigation pane, click Storage > Aggregates.
3.
Select the 32-bit aggregate whose size you want to increase and click Edit.
4.
Add the disks and click Save and Close.
