Remove-StoragePool and Set-StoragePool errors

I am trying remove the StoragePool using the remove-StoragePool PowerShell command but getting the error - The storage pool could not complete the operation because its health or operational status does not permit it.

So, I try to set it to read-write using set-StoragePool command but getting the following - Access denied.  I am running the PowerShell as the local administrator.

Please see the below output.

PS C:\> get-storagepool
