74 The following commands are supported:
75 .Bl -tag -width "rebuild"
79 devices on the channel are probed and attached as
84 devices on the channel are removed from the kernel,
85 and all outstanding transfers etc. are returned back to the system marked
90 Both devices on the channel are reset and
91 initialized to the parameters the ATA driver has stored internally.
92 Devices that has gone bad and no longer responds to the probe, or devices
93 that has physically been removed are removed from the kernel.
94 Likewise are devices that show up during a reset, probed and attached.

100 If the mode arguments are given, the ATA driver
101 is asked to change the transfer modes to those given.
