Please read this document section:
https://docs.netapp.com/ontap-9/topic/com.netapp.doc.dot-cm-psmg/GUID-4D43889E-7200-46D3-8182-A6AD836FE317.html

Specifically:

How hot spare disks work
A hot spare disk is a disk that is assigned to a storage system and is ready for use, but is not in use by a RAID group and does not hold any data.
How low spare warnings can help you manage your spare disks
By default, warnings are issued to the console and logs if you have fewer than one hot spare drive that matches the attributes of each drive in your storage system. You can change the threshold value for these warning messages to ensure that your system adheres to best practices.

Looking at the list supplied, there are 11 disks.

Either one is broken or missing. Trying to see if that is the case.
