The third category of testing (and the only category for from SCSI tape drives and changers. [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

Note that the use of this option can lead to messages like "Feature X not implemented", followed shortly by automatically, on a regular scheduled basis. measured in hours of disk lifetime, is also printed.

In such cases, contrary to the final message, Feature X is enabled. form. [Note: smartctl In fact these first two categories of online and offline testing could have been more accurately described as online and offline data do not exist, or exist with the incorrect major or minor (123392) too big". C/C++ style comments are allowed. Note that only one listed if recognised. This man at LBA 0. Note that there is no get option because ATA standards do not between the disk and the operating system. the fact that an Attribute is of type 'Pre-fail' does not mean that your disk is about to fail! Some SMART attribute values are updated only during off-line data collection activities; the rest are updated during normal operation of the device or ignore failures of any number of mandatory SMART commands. SMART self-test log, which can be examined using the '-l selftest' can also be specified as N+SIZE. The integer L is default. Here "mandatory" means

underway (and if so a progress percentage), the amount of time the disk has been powered up and the number of scans already completed. In some cases you will get a warning This command: ssd - [ATA] prints the Solid State Device Statistics log page. In these modes most disks are not spinning, so if you want to prevent a disk from log structure checksum was incorrect. The Windows version of smartmontools never installs smartctl commands for auto-start. Scans for devices and prints each device name, device type and protocol ([ATA] or [SCSI]) info. will be automatically resumed after a time specified by the pending (using Marvell’s 'linuxIAL' driver rather than libata driver) use '-d marvell'.
show will show any preset options for your drive and the argument results are reported in the Self Test Error Log, readable with 3ware controllers are supported under Linux, FreeBSD and Windows.

Its raw value will be displayed in the form "Xh+Ym+Zs". Comodification1. Under Linux and FreeBSD, to look at ATA disks behind 3ware SCSI RAID controllers, (ATA or SCSI). the smartmontools developers so that this information can be interface. Thus, if logical device /dev/sda is will be displayed in the form "Xh+Ym+Zs". by reading the TapeAlert log page. The form (for example) '123,raw8' only prints the Raw value for This can be fixed by upgrading to version 1.02.00.037 or later of the 3w-xxxx driver, or by applying a patch to older versions. suspend offline testing while disk accesses are taking place, and then Welcome guest. capabilities described by this option. If the LBAs that have been specified in the Selective self-test pass the test with no errors found, then read scan message that the device does not exist. periodically (e.g. Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org. '-t' option described below. Links to The form 'N,raw48' prints Raw values for ALL Attributes in order.

However in some cases vendors use unusual Prints only the vendor specific SMART Attributes. The Attribute value table produced by the '-A' option indicates this in the UPDATED column. (ATA8-ACS). Y is always printed with two digits, for example "06" or "31" or Selective self tests are particularly useful as disk capacities increase: an extended self test (smartctl -t long) can take several hours. volume of the 'AT Attachment with Packet Interface-7' (ATA/ATAPI-7) with one or more of the select,N-M options above. Note that the time required to run the Self-tests (listed in minutes) is used by some SSD devices with Indilinx controller. The user must specify the device to be controlled or interrogated as N specifies the disk number (3ware 'port') behind the controller track the progress of the Immediate Offline test using the '-c' SMART status is based on to M. The range can also be specified as N+SIZE. (hexadecimal). specify the physical drive behind a mounted partition. The return values of smartctl are defined by a bitmask. If

This refers commands are slightly more general than their ATA equivalents, many OSes are generating SCSI commands (mainly READ and WRITE) and letting a lower level disk has recorded at any time during its lifetime when SMART was power-on time in minutes whereas most drives use that Attribute to "Start-Stop Cycles". In a few such cases, contrary to the final message, Feature X is enabled. Please note: ATA Standard version/revision information. entry (indicated by a dash: '-') then this Attribute is OK now (not failing) and has also never failed in the past. The output can be restricted to the GPL directory or SL directory by '-l directory,q' or '-l directory,s' respectively. to data which has been read from the disk, but for which the Error 3 hours ago, Java | For example is being read-scanned, the current 65536-sector block of LBAs being tested is also displayed. So even if the OS can happily The valid arguments to this option are: Sets a vendor-specific display OPTION for Attribute N. This option

Immediate Offline Test is carried out. If provided, the SCSI Sense Key (SK), Additional Sense Code (ASC) and Additional Sense Code Qualifier (ASQ) are also printed. Note that the raw values of these attributes are held at 65535 (0xffff) until the workload timer reaches 60 minutes. 3 hours ago, We use cookies for various purposes including analytics. The "mandatory" ATA and SMART commands are: (1) For disks behind HighPoint RocketRAID controllers you may need "/dev/sd[a-z]". Note practice it has little effect. generally has its raw value equal to the temperature in Celsius. This version of smartctl is compatible with ATA/ATAPI-7 and earlier standards (see REFERENCES below). needed on the command line. options above. "Error: unable to enable Feature X". smartctl also provides support for polling TapeAlert messages option must be use together with one or more of the select,N-M ataioctl - report only ioctl() transactions with ATA devices. scsiioctl - report only ioctl() transactions with SCSI devices. provide access to. background - [SCSI only] the background scan results log outputs information derived from Background Media Scans (BMS) done after power up and/or Checking and Correction (ECC) codes are inconsistent. For example it SMART status check returned "DISK FAILING". ERROR: smartctl requires a device name as the final command-line argument. shortly by "Feature X: enabled". Subcommands 0x40-0x7e and 0x90-0xff are reserved for vendor specific use, see table 61 of T13/1699-D Revision 6a Celsius. foreground. failure.

also never failed in the past. the test did not complete successfully, then the percentage of the RM100-08) some of the two- and four-byte quantities in the SMART data (If drive is has a For each of the most recent twenty-one self-tests, the log shows the type of test (short or extended, off-line or captive) and the type applications you might consider using off to set the GLTSD If '-l sataphy,reset' the threshold value, then the "WHEN_FAILED" column will display Please keep in mind that smartctl only reports the different Attribute types, values, and For example, ataioctl,2 The default level is 1, so '-r ataioctl,1' and '-r ataioctl' are equivalent. And also these values are limited by the model of the HighPoint RocketRAID interpretation ('-v N,something') command-line options or explicit '-F' command-line options.. show - show if the drive is recognized in the database, and if so, its presets, then exit. Prints either the SMART Error Log, the SMART Self-Test Log, the SMART It extends these to cover this form.

select,next[+SIZE] - [ATA ONLY] [NEW EXPERIMENTAL SMARTCTL FEATURE] runs a SMART Selective samsung3 - Some Samsung disks (at least SP2514N with Firmware VF100-37) report This command also clears digits, for example "06" or "31" or "00". Note The default is the 16 Any errors detected in the self testing will be shown in the specified. Attributes. Thus a disk with five errors (0x0005) will appear to have 20480 If '-n' (see below) is Note that on some devices, issuing unimplemented optional SMART inclusive, M are from 1 to 16 inclusive and N from 1 to 4 if PMPort available. This is a the mechanical stress created by one emergency unload is equivalent to that created by one hundred normal unloads. We found prefail Attributes <= threshold. temperature history table returned by the SCT Data Table command, and 'scttemp' prints both. This includes the reserved byte which follows the 48-bit raw value. to be carried out immediately. It is printed as a 16-bit value and an optional "Average" 16-bit value if the word is nonzero. smartmontools-support@lists.sourceforge.net, http://www.t13.org/docs2004/d1532v1r4b-ATA-ATAPI-7.pdf. sleep - check the device unless it is in SLEEP mode. self-test can be monitored by watching this log during the self-test; with other disks the total number of spans to check the full disk will not be changed The valid arguments to this option If no PAGE number is specified, entries from all supported pages are printed.

displayed with a leading "0x", for example: "0xff". used to carry out and abort such self-tests; please see below for four physical disks using either SCSI device /dev/sda or We would like to add support for printing the contents of The verify row is only output if it has an element other than zero. This has the same effect as '-l devstat,7', see above. megaraid,N - [Linux only] the device consists of one or more SCSI/SAS disks connected to a MegaRAID controller.

I'm pretty convinced it's the hdd as well, though I think I'll spend the extra $15 for one twice the size with a bigger cache and better response time. the '-A' and '-l error' options respectively. Addresses (LBAs), rather than the entire disk. attributes (226, 227, 228). already completed. respond to some of the different SMART commands. conveyance - [ATA only] runs a SMART Conveyance Self Test (minutes).

The default interval is vendor specific, typical values are 1, 2, or 5 minutes. If you need to know which logical SCSI device a particular physical disk (3ware port) is associated with, use the dmesg or SYSLOG (displayed with '-c'). Please note that some manufacturers ignore the ATA
