hard drive - SAS-3 vs SAS-2 HDDs - Server Fault linux sas drive serial number

Reply MM Posted February 8, 2012 at 1:30 pm | Permalink So far I have tried only RANUNI.

Lower-numbered firmware versions will give (harmless) SCSI error messages and noSMART information.areca,N/E - [FreeBSD, Linux, Windows and Cygwin only] [NEW EXPERIMENTAL SMARTCTL FEATURE] the device consists of one or more SATA disks connected toan Areca SAS RAID controller.

The first category, called "online" testing, has no effect on the performance of the device.It is turned on by the '-s on' option.The second category of testing is called "offline" testing.

The sameapplies if the specified PORT does not exist or is not connected to a disk.usbsunplus - this device type is for SATA disks that are behind a SunplusIT USB to SATA bridge.marvell - [Linux only] interact with SATA disks behind Marvell chip-set controllers (using the Marvell rather than libata driver).megaraid,N - [Linux only] the device consists of one or more SCSI/SAS disks connected to a MegaRAID controller.

This raw formatis used by some SSD devices with Indilinx controller.min2hour - Raw Attribute is power-on time in minutes.

Read-ahead policy may improve system performance if the data is actually written to sequential sectors of the logical drive.No-Read-Ahead.

The default interval is vendor specific, typical values are 1, 2, or 5 minutes.scterc[,READTIME,WRITETIME] - [ATA only] prints values and descriptions of the SCT Error Recovery Control settings.

See '-l gplog,...' above forparameter syntax.For example, all these commands:smartctl -l gplog,0x80,10-15 /dev/sdasmartctl -l gplog,0x80,10+6 /dev/sdasmartctl -l smartlog,0x80,10-15 /dev/sdaprint pages 10-15 of log 0x80 (first host vendor specific log).The hex dump format is compatible with the 'xxd -r' command.

If your version of smartctl supports 48-bit ATA commands, both the General Purpose Log (GPL) and SMART Log (SL) directories are printed in one combinedtable. linux scsi disk serial number

Only run captive tests on drives without any mountedpartitions![SCSI] Runs the self-test in "Foreground" mode.-X, --abortAborts non-captive SMART Self Tests.

This is for ATA disks that have a SCSI to ATA Translation (SAT) Layer (SATL)between the disk and the operating system.

Numbers missing from the filter are treated as wildcards: hence "5:0:1" and "5:0:1:-" are the same.
