VMAX3 100K hot spares

I am having trouble interpreting output from the "symdisk list" command on my VMAX3 100K. I am trying to determine if I have hot spare disks and if so, how many. The symm is running 5977.952.892. I have a single SRP with two disk groups: one with 10K disks and one with EFD.

When I run the "symdisk list -hotspare" command, it returns "No matching disks were found".

"symdisk list -isspare" returns the same result.
