+.B \-\-scan
+Scans for devices and prints each device name, device type and protocol
+([ATA] or [SCSI]) info. May be used in conjunction with \'\-d TYPE\'
+to restrict the scan to a specific TYPE. See also info about platform
+specific device scan and the \fBDEVICESCAN\fP directive on

+Same as \-\-scan, but also tries to open each device before printing
+device info. The device open may change the device type due
+to autodetection (see also \'\-d test\').

-Translation (SAT) Layer (SATL) between the disk and the operating system.

+- attempt to guess the device type from the device name or from
+controller type info provided by the operating system or from
+a matching USB ID entry in the drive database.
+This is the default.
+
+.I test
+- prints the guessed type, then opens the device and prints the
+(possibly changed) TYPE name and then exists without performing
+any further commands.
+
+.I ata
+\- the device type is ATA. This prevents
+\fBsmartctl\fP
+from issuing SCSI commands to an ATA device.
+
+.\" %IF NOT OS Darwin
+.I scsi
+\- the device type is SCSI. This prevents
+\fBsmartctl\fP
+from issuing ATA commands to a SCSI device.
+
+.I sat[,auto][,N]
+\- the device type is SCSI to ATA Translation (SAT).
+This is for ATA disks that have a SCSI to ATA Translation (SAT) Layer
+(SATL) between the disk and the operating system.
SAT defines two ATA PASS THROUGH SCSI commands, one 12 bytes long and
-the other 16 bytes long that \fBsmartctl\fP will utilize when this device
-type is selected. The default is the 16 byte variant which can be
+the other 16 bytes long. The default is the 16 byte variant which can be
overridden with either \'\-d sat,12\' or \'\-d sat,16\'.
-The \'usbcypress\' device type is for ATA disks that are behind a Cypress
-usb-pata bridge. This will use the ATACB proprietary scsi pass through command. There is no autodetection at the moment. The best way to know if your device support it, is to check your device usb id (most Cypress usb ata bridge got vid=0x04b4, pid=0x6830) or to try it (if the usb device doesn't support ATACB, smartmontools print an error).
-The default scsi operation code is 0x24, but although it can be overridden
-with \'\-d usbcypress,0xn\', where n is the scsi operation code,
+[NEW EXPERIMENTAL SMARTCTL FEATURE] If \'-d sat,auto\' is specified,
+device type SAT (for ATA/SATA disks) is
+only used if the SCSI INQUIRY data reports a SATL (VENDOR: "ATA ").
+Otherwise device type SCSI (for SCSI/SAS disks) is used.
+
+.I usbcypress
+\- this device type is for ATA disks that are behind a Cypress USB to PATA
+bridge. This will use the ATACB proprietary scsi pass through command.
+The default SCSI operation code is 0x24, but although it can be overridden
+with \'\-d usbcypress,0xN\', where N is the scsi operation code,
you're running the risk of damage to the device or filesystems on it.
-[NEW EXPERIMENTAL SMARTCTL FEATURE] The \'usbjmicron\' device type is for
-SATA disks that are behind a JMicron USB to PATA/SATA bridge. The 48-bit
-ATA commands (required e.g. for \'\-l xerror\', see below) do not work with
-all of these bridges and are therefore disabled by default. These commands
-can be enabled by \'\-d usbjmicron,x\'. CAUTION: Specifying \',x\' for a
-device which do not support it results in I/O errors and may disconnect
-the drive. The port can be specified by \'\-d usbjmicron[,x],PORT\' where
-PORT is 0 (master) or 1 (slave). This is not necessary if only one disk is
-connected to the USB bridge. If two disks are connected, an error message
-is printed if no PORT is specified.
-
-[NEW EXPERIMENTAL SMARTCTL FEATURE] The \'usbsunplus\' device type is for
-SATA disks that are behind a SunplusIT USB to SATA bridge.
-
-Under Linux, to look at SATA disks behind Marvell SATA controllers
-(using Marvell's \'linuxIAL\' driver rather than libata driver) use \'\-d marvell\'. Such
-controllers show up as Marvell Technology Group Ltd. SATA I or II controllers
-using lspci, or using lspci \-n show a vendor ID 0x11ab and a device ID of
-either 0x5040, 0x5041, 0x5080, 0x5081, 0x6041 or 0x6081. The \'linuxIAL\' driver
-seems not (yet?) available in the Linux kernel source tree, but should be available
-from system vendors (ftp://ftp.aslab.com/ is known to provide a patch with the driver).

+see below) do not work with all of these bridges and are therefore disabled by
+default. These commands can be enabled by \'\-d usbjmicron,x\'.
+If two disks are connected to a bridge with two ports, an error message is printed
+if no PORT is specified.
+The port can be specified by \'\-d usbjmicron[,x],PORT\' where PORT is 0
+(master) or 1 (slave). This is not necessary if the device uses a port
+multiplier to connect multiple disks to one port. The disks appear under
+separate /dev/ice names then.
+CAUTION: Specifying \',x\' for a device which does not support it results
+in I/O errors and may disconnect the drive. The same applies if the specified

.B \-n POWERMODE, \-\-nocheck=POWERMODE
[ATA only] Specifies if \fBsmartctl\fP should exit before performing any
checks when the device is in a low\-power mode. It may be used to prevent
a disk from being spun\-up by \fBsmartctl\fP. The power mode is ignored by
-default. The allowed values of POWERMODE are:
+default. A nonzero exit status is returned if the device is in one of the
+specified low\-power modes (see RETURN VALUES below).
+
+Note: If this option is used it may also be necessary to specify the device
+type with the \'-d\' option. Otherwise the device may spin up due to
+commands issued during device type autodetection.

+[SCSI] For SCSI devices this toggles the value of the Global Logging
+Target Save Disabled (GLTSD) bit in the Control Mode Page. Some disk
manufacturers set this bit by default. This prevents error counters,
power\-up hours and other useful data from being placed in non\-volatile
storage, so these values may be reset to zero the next time the device
saving counters to non\-volatile storage. For extreme streaming\-video
type applications you might consider using \fIoff\fP to set the GLTSD

+\- [ATA only] Gets/sets the Automatic Acoustic Management (AAM) feature
+(if supported). A value of 128 sets the most quiet (slowest) mode and 254
+the fastest (loudest) mode, \'off\' disables AAM. Devices may support
+intermediate levels. Values below 128 are defined as vendor specific (0)
+or retired (1\-127). Note that the AAM feature was declared obsolete in
+ATA ACS-2 Revision 4a (Dec 2010).

+attempt to enable APM and set the specified value, \'off\' disables APM.
+Note the actual behavior depends on the drive, for example some drives disable
+APM if their value is set above 128. Values below 128 are supposed to allow
+drive spindown, values 128 and above adjust only head-parking frequency,
+although the actual behavior defined is also vendor-specific.

+.I standby,[N|off]
+\- [ATA only] Sets the standby (spindown) timer and places the drive in the
+IDLE mode. A value of 0 or \'off\' disables the standby timer.
+Values from 1 to 240 specify timeouts from 5 seconds to 20 minutes in 5
+second increments. Values from 241 to 251 specify timeouts from 30 minutes
+to 330 minutes in 30 minute increments. Value 252 specifies 21 minutes.
+Value 253 specifies a vendor specific time between 8 and 12 hours. Value
+255 specifies 21 minutes and 15 seconds. Some drives may use a vendor
+specific interpretation for the values. Note that there is no get option
+because ATA standards do not specify a method to read the standby timer.

The valid arguments to this option are:
.I offline

+\- [ATA] runs SMART Immediate Offline Test. This immediately
starts the test described above. This command can be given during
normal system operation. The effects of this test are visible only in
that it updates the SMART Attribute values, and if errors are
found they will appear in the SMART error log, visible with the \'\-l error\'
-option. [In the case of SCSI devices runs the default self test in
-foreground. No entry is placed in the self test log.]
+option.
If the \'\-c\' option to \fBsmartctl\fP shows that the device has the
"Suspend Offline collection upon new command" capability then you can
try to track the progress of the test with \'\-c\', as it will abort
the test.
+.I offline
+\- [SCSI] runs the default self test in foreground. No entry is placed
+in the self test log.

.I short
-\- runs SMART Short Self Test (usually under ten minutes).
-[Note: in the case of SCSI devices,
-this command option runs the "Background short" self\-test.]
+\- [ATA] runs SMART Short Self Test (usually under ten minutes).
This command can be given during normal system operation (unless run in
captive mode \- see the \'\-C\' option below). This is a
test in a different category than the immediate or automatic offline
self\-test can be monitored by watching this log during the self\-test; with other disks
use the \'\-c\' option to monitor progress.
+.I short
+\- [SCSI] runs the "Background short" self\-test.

.I long

-[Note: in the case of SCSI devices,
-this command option runs the "Background long" self\-test.]
-This is a

longer and more thorough version of the Short Self Test described
above. Note that this command can be given during normal
system operation (unless run in captive mode \- see the \'\-C\' option below).
+.I long

done in captive mode \- see the \'\-C\' option below).

The following variants of the selective self\-test command use spans based
on the ranges from past tests already stored on the disk:
options above. The value of this option is preserved between selective
self\-tests.
-.I scttempint,N[,p]
-\- [ATA only] set the time interval for SCT temperature logging to N
-minutes. If \',p\' is specified, the setting is preserved across power
-cycles. Otherwise, the setting is volatile and will be reverted to
-default (1 minute), or last non-volatile setting by the next hard reset.
-This command also clears the temperature history table. See
-\'\-l scttemp\' above for more information about SCT temperature logging.
+.I vendor,N
+\- [ATA only] issues the ATA command SMART EXECUTE OFF-LINE IMMEDIATE
+with subcommand N in LBA LOW register. The subcommand is specified as
+a hex value in the range 0x00 to 0xff. Subcommands 0x40-0x7e and
+0x90-0xff are reserved for vendor specific use, see table 61 of
+T13/1699-D Revision 6a (ATA8-ACS). Note that the subcommands
+0x00-0x04,0x7f,0x81-0x84 are supported by other smartctl options
+(e.g. 0x01: \'\-t short\', 0x7f: \'\-X\', 0x82: \'\-C \-t long\').
+
+\fBWARNING: Only run subcommands documented by the vendor of the
+device.\fP
+
+Example for Intel (X18/X25\-M G2, 320, 520 and 710 Series) SSDs only:
+The subcommand 0x40 (\'\-t vendor,0x40\') clears the timed workload
+related SMART attributes (226, 227, 228). Note that the raw values of
+these attributes are held at 65535 (0xffff) until the workload timer
+reaches 60 minutes.
+
+.I force
+\- [ATA only] start new self\-test even if another test is already running.
+By default a running self\-test will not be interrupted to begin another
+test.
+.I scttempint,N[,p]
+\- is no longer supported, use \'\-l scttempint,N[,p]\' instead, see above.

.B \-C, \-\-captive

does, a good place to start is with Sections 4.8 and 6.54 of the first
volume of the \'AT Attachment with Packet Interface\-7\' (ATA/ATAPI\-7)
