				Changing the storage elements of a storage drive may result in the loss of all
				data on that storage drive.
				The drive may need to reinitialize after
				.Fl d
				or
				.Fl r
				commands.
				The data on the drive is inaccessible until one of these commands complete.
				Once one of these commands start, the drive is format corrupt until the
				operation successfully completes.
				While format corrupt, no read or write I/O is possible to the drive.
				If the drive power cycles, it will remain format corrupt and the operation
				must be restarted.
				TEST UNIT READY or
				.Dq camcontrol tur
				can monitor an in-progress depop operation.

				.It Fl d
				Remove the physical element from service or set the capacity point specified by the
				.Fl e
				or
				.Fl c
				flags.
				The drive's capacity may be reduced by this operation.
				.It Fl e Ar element
				Specify the physical element to remove from service.
				Valid only for the

				.It Fl l
				Report the current status of the physical elements of a drive.
				.It Fl r
				Restore all the eligible physical elements to service.
