If you plan to add a spare array LUN to an aggregate by specifying its name, you need to make sure that the checksum type of the array LUN you want to add is the same as the aggregate checksum type.
You cannot mix array LUNs of different checksum types in an array LUN aggregate. The checksum type of the aggregate and the checksum type of the array LUNs added to it must be the same.
If you specify a number of spare array LUNs to be added to an aggregate, by default Data ONTAP selects array LUNs of the same checksum type as the aggregate.

The output shows information about the spare disks or array LUNs on the system, including the checksum type of each. You can add a block checksum array LUN to a block checksum aggregate and a zoned array LUN to either a zoned aggregate or an AZCS checksum aggregate.
