You can use System Manager to assign array LUNs to an existing aggregate and manage array LUNs.
More information
Assigning array LUNs
You can use System Manager to assign unassigned array LUNs to an existing aggregate to increase the size of the aggregate.
Reassigning spare array LUNs to nodes
You can use System Manager to reassign the ownership of spare array LUNs from one node to another to increase the capacity of an aggregate.
Zeroing spare array LUNs
You can use System Manager to erase all the data and to format the spare array LUNs by writing zeros to the array LUNs. These array LUNs can then be used in new aggregates.
About disks and array LUNs
A disk is the basic unit of storage for storage systems that use Data ONTAP to access native disk shelves. An array LUN is the basic unit of storage that third-party storage arrays provide to storage systems that run Data ONTAP.
How disks and array LUNs become available for use
When you add a disk or array LUN to a system running Data ONTAP, the disk or array LUN goes through several stages before it can be used by Data ONTAP to store data or parity information.
Rules for mixing array LUNs in an aggregate
Data ONTAP does not support the mixing of different types of storage in the same aggregate because it causes performance degradation.
Array LUNs window
The Array LUNs window enables you to assign ownership to your array LUNs and to add them to an aggregate.
