31<h4>DESCRIPTION</h4>
32<ul>
33The diskdelay command provides the user with a single
34point of control over all the disks, either to specify a default
35delay value in the rc-file, or to change the value dynamically.
36
37The parameter to diskdelay is in micro-seconds (of simulated
38time), so for example "diskdelay 8000" will simulate a disk with
39an average service time of 8 milli-seconds.
40<p>
41Individual disks can be configured with individual diskdelays,
42but which value takes precedence is currently a matter of the
43coding style of each disk simulator.
44<p>
45Without arguments, diskdelay displays the current disk delay settings.
46<p>
47In the form, diskdelay <i>read-write-delay</i>, both the
48read and write disk delay are set to <i>read-write-delay</i>.
49<p>
50In the form, diskdelay <i>read-delay</i>/<i>write-delay</i>, both the
51read and write disk delay are set to <i>read-delay</i> and
52<i>write-delay</i>, respectively.
