.SH DESCRIPTION
The \fBdiskctl\fR tool allows one to view and manage settings of,
and perform actions on, disk drives. The following paragraph lists the
commands that are currently supported by this tool.
Please note that not all disks and drivers support all commands.

The call will not return until the cache flush has completed.

.TP 20
.B diskctl /dev/c1d2 flush
