78 utility is a control program that provides the user access and control to the
86 can cause severe system crashes and loss of data if used improperly.
88 exercise caution when using this command!
92 argument is the number of the ATA channel on which to operate.
93 The following commands are supported:
94 .Bl -tag -width "rebuild"
98 Devices on the channel are probed and attached as
103 Devices on the channel are removed from the kernel,
104 and all outstanding transfers etc. are returned back to the system marked
109 Both devices on the channel are reset and
110 initialized to the parameters the ATA driver has stored internally.
111 Devices that have gone bad and no longer respond to the probe, or devices
112 that have physically been removed, are removed from the kernel.
113 Likewise are devices that show up during a reset, probed and attached.
127 In case the RAID has a
132 must be specified in number of sectors.
133 The RAID will be created
134 of the individual disks named
136 .Ar disk0 ... diskN .
139 Although the ATA driver allows for creating an ATA RAID on disks with any
140 controller, there are restrictions.
141 It is only possible to boot on
142 an array if it is either located on a
144 ATA RAID controller like
145 the Promise or Highpoint controllers, or if the RAID declared is of
151 the partition to boot must
152 reside on the first disk in the SPAN.
154 Delete a RAID array on a RAID capable ATA controller.
156 Rebuild a RAID1 array on a RAID capable ATA controller.
158 Get the status of an ATA RAID.
160 Without the two mode arguments, the current transfer modes of both
162 If the mode arguments are given, the ATA driver
163 is asked to change the transfer modes to those given.
165 will reject modes that are not supported by the hardware.
170 case does not matter.
171 If one of the devices mode should not be changed, use a nonexisting mode
174 and the mode will remain unchanged.
176 Currently supported modes are:
181 .Cm PIO1 , PIO2 , PIO3 , PIO4 ,
197 Show info about the attached devices on the
199 The device name and manufacture/version strings are shown.
201 Show detailed info about the device on
203 where device is 0 for master and 1 for slave.
205 Show detailed info about the enclosure on
207 where device is 0 for master and 1 for slave.
208 Fan RPM speed, enclosure temperature, 5V and 12V levels are shown.
210 Show info about all attached devices on all active controllers.
213 To see the devices' current access modes, use the command line:
215 .Dl "atacontrol mode 0"
217 which results in the modes of the devices being displayed as a string
219 .Bd -literal -offset indent
224 This means that ata0-master is in DMA mode,
225 ata0-slave is in PIO mode,
227 You can set the mode with
229 and a string like the above,
232 .Dl "atacontrol mode 0 PIO4 PIO4"
234 The new modes are set as soon as the
