* Any disk not have 'aggregate' property is considered as free disk.
* Added comments indicate how spare and free disk works on ONTAP:
1. Spare == free disk
2. Zeroed spare disk == OK | SPARE | FREE
3. Non-zeroed spare disk == STOPPED | SPARE | FREE
Changes in V2:
* Should not mark partner filer's disks as free.
# Don't check status of partner's disks, simply mark as STATUS_OTHER.
