blktool - Display or change block device settings

Beschreibung

blktool is used for querying and/or changing settings of a block device.
device is the name of the block device to query or modify.

tune low-level block device parameters

blktool is used for querying and/or changing settings of a block device. It is like hdparm but a more general tool, as it works on SCSI, IDE and SATA devices.

This program is for those who know what they're doing and it should be used at your own risk as it could cause damage to your hardware.

Optionen

Unix	GNU	Parameter	Beschreibung
-f			For a few commands, blktool will flush the buffers of the block device out to disk, before performing the requested command. Specify this option, "force", disables any flushing blktool would attempt to do.
-t		class	where class is one of 'ide', 'ata', 'scsi', 'i2o', or 'auto' to override the default auto-detection of device class.

 = TMP =
-== COMMANDS ==
-acoustic-mgmt
-       Query or set underlying device's acoustic level.
-block-sz
-       Query or set device block size.
-bus-id Query device bus id.
-bus-state
-       Query or set device bus state (0 off, 1 on, 2 tristate)
-class  Query  the  detected (or overridden, via -t) device class.  Typically this will result in 'ATA'
-       or 'SCSI' for most devices.  Detection is based on device major; thus your SATA device may  ap‐
-       pear as 'SCSI'.
-cd-speed
-       Set CD-ROM device speed (in Kbytes/sec).
-defect-mgmt
-       Toggle underlying device's defect management (obsolete).
-dev-keep-settings
-       Toggle underlying device's revert-to-defaults-on-reset feature.
-dev-read-ahead
-       Toggle underlying device's read-ahead feature.
-dma    Toggle DMA data transfer.  Omitting the on/off argument will print the current state.
-geometry
-       Query device geometry (cylinders / heads / sectors / etc.).
-i2o-rcache
-       Query or set an I2O block device's read cache.
-i2o-wcache
-       Query or set an I2O block device's write cache.
-id     Query IDENTIFY [PACKET] DEVICE data.
-keep-settings
-       Keep settings across device resets.  Omitting the on/off argument will print the current state.
-media  Lock in (or unlock) a removable device.
-multiple-count
-       Set multiple count for use in READ/WRITE MULTIPLE commands.
-no-write-err
-       Toggle ignore-write-errors flag.  Omitting the on/off argument will print the current state.
-pio-data
-       ATA  PIO  data  transfer via 16-bit or 32-bit I/O.  Omitting the on/off argument will print the
-       current state.
-pio-mode
-       Set underlying ATA device's PIO data transfer mode.
-pm-mode
-       Set underlying device's Advanced Power Management mode.
-queued-depth
-       Query or set underlying device's queue depth.
-read-ahead
-       Query or set block device read-ahead (in units of sectors).
-readonly
-       Toggle block device read-only setting.  Omitting the on/off argument  will  print  the  current
-       state.
-reread-part
-       Re-read partition table.
-reset  Execute device reset.
-sector-sz
-       Query device sector size.
-sleep  Put device to sleep immediately.
-standby
-       Put device in standby mode.
-unmask-irq
-       Toggle unmasked irqs.  Omitting the on/off argument will print the current state.
-version
-       Print version number and exit.
-wcache Toggle underlying device's writeback cache.
