Attach an ATA channel. Devices on the channel are probed and attached as is done on boot.
detach
Detach an ATA channel. Devices on the channel are removed from the kernel, and all outstanding transfers etc. are returned back to the system marked as failed.
reinit
Reinitialize an ATA channel. Both devices on the channel are reset and initialized to the parameters the ATA driver has stored internally. Devices that have gone bad and no longer respond to the probe, or devices that have physically been removed, are removed from the kernel. Likewise are devices that show up during a reset, probed and attached.
create
Create a type ATA RAID. The type can be RAID0 (stripe), RAID1 (mirror), RAID0+1, SPAN or JBOD. In case the RAID has a RAID0 component, the interleave must be specified in number of sectors. The RAID will be created of the individual disks named .Bk -words disk0 ... diskN. .Ek
Although the ATA driver allows for creating an ATA RAID on disks with any controller, there are restrictions. It is only possible to boot on an array if it is either located on a "real" ATA RAID controller like the Promise or Highpoint controllers, or if the RAID declared is of RAID1 or SPAN type; in case of a SPAN, the partition to boot must reside on the first disk in the SPAN.
delete
Delete a RAID array on a RAID capable ATA controller.
addspare
Add a spare disk to an existing RAID.
rebuild
Rebuild a RAID1 array on a RAID capable ATA controller.
status
Get the status of an ATA RAID.
mode
Without the mode argument, the current transfer modes of the device are printed. If the mode argument is given, the ATA driver is asked to change the transfer mode to the one given. The ATA driver will reject modes that are not supported by the hardware. Modes are given like "PIO3", "udma2", "udma100", case does not matter.
Currently supported modes are: PIO0, PIO1, PIO2, PIO3, PIO4, WDMA2, UDMA2 (alias UDMA33), UDMA4 (alias UDMA66), UDMA5 (alias UDMA100) and UDMA6 (alias UDMA133). The device name and manufacture/version strings are shown.
cap
Show detailed info about the device on device.
info
Show info about the attached devices on the channel.
list
Show info about all attached devices on all active controllers.
