Is there a command that lists the usable capacity of disks on netapp filer?
If a filer is has storage from a third party, how can these be identified using Data ONTAP commands?.

Thanks for the respose, I have the below output from the "aggr status -r" command, output lists only the used and phsysical capacities.
How can usable capacity (usually lesser than the physical capacity) of the disk be determined?
>aggr status -r
Aggregate aggr_1 (online, raid_dp) (block checksums)
Plex /aggr_1/plex0 (online, normal, active, pool0)
RAID group /aggr_1/plex0/rg0 (normal)
RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks)
dparity 0z.112 0a 7 3 FC:A 0 FCAL 10000 136000/278528000 137422/281442144

But, the NetApp Storage administration guide suggests a formula,
Usable Capacity = Raw Capacity - System Reserve Capacity
which indicates usable capacity of a disk is not equal to the raw capacity of the disk.
For Example, let there be disk of physical capacity 100GB, 10GB of the disk space is used for metadata and other purposes. In this case, only 90GB of disk space is available for usage (usable capacity)
How can this be obtained on ONTAP?
