ATACONTROL(8) BSD System Manager's Manual ATACONTROL(8) NAME atacontrol -- ATA device driver control program SYNOPSIS atacontrol <command> args atacontrol attach channel atacontrol detach channel atacontrol reinit channel atacontrol create type [interleave] disk0 ... diskN atacontrol delete raid atacontrol rebuild raid atacontrol status raid atacontrol mode channel [mastermode slavemode] atacontrol info channel atacontrol cap channel device atacontrol enclosure channel device atacontrol list DESCRIPTION The atacontrol utility is a control program that provides the user access and control to the FreeBSD ata(4) subsystem. The atacontrol utility can cause severe system crashes and loss of data if used improperly. Please exercise caution when using this command! The channel argument is the number of the ATA channel on which to oper- ate. The following commands are supported: attach 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 re- spond to the probe, or devices that have physically been re- moved, 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 or SPAN (JBOD). In case the RAID has a RAID0 component, the interleave must be specified in number of sec- tors. The RAID will be created of the individual disks named disk0 ... diskN. Although the ATA driver allows for creating an ATA RAID on disks with any controller, there are restrictions. It is only possi- ble 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. rebuild Rebuild a RAID1 array on a RAID capable ATA controller. status Get the status of an ATA RAID. mode Without the two mode arguments, the current transfer modes of both devices are printed. If the mode arguments are given, the ATA driver is asked to change the transfer modes to those 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. If one of the devices mode should not be changed, use a nonexisting mode as argument (i.e. "XXX"), and the mode will remain unchanged. Currently supported modes are: BIOSDMA, PIO0 (alias BIOSPIO), PIO1, PIO2, PIO3, PIO4, WDMA2, UDMA2 (alias UDMA33), UDMA4 (alias UDMA66), UDMA5 (alias UDMA100) and UDMA6 (alias UDMA133). info Show info about the attached devices on the channel. The device name and manufacture/version strings are shown. cap Show detailed info about the device on channel device where de- vice is 0 for master and 1 for slave. enclosure Show detailed info about the enclosure on channel device where device is 0 for master and 1 for slave. Fan RPM speed, enclo- sure temperature, 5V and 12V levels are shown. list Show info about all attached devices on all active controllers. EXAMPLES To see the devices' current access modes, use the command line: atacontrol mode 0 which results in the modes of the devices being displayed as a string like this: Master = WDMA2 Slave = PIO4 This means that ata0-master is in DMA mode, ata0-slave is in PIO mode, and so forth. You can set the mode with atacontrol and a string like the above, for example: atacontrol mode 0 PIO4 PIO4 The new modes are set as soon as the atacontrol command returns.
