  • 1.  Access to raw SMART data?

    Posted Feb 19, 2014 08:01 PM

    Is there a way to get the full (raw) smart data for a disk?

    Using esxcli I can get some of the data:-

    # esxcli storage core device smart get -d t10.ATA_____Corsair_Force_GT________________________13527920000097950113

    Parameter                     Value  Threshold  Worst

    ----------------------------  -----  ---------  -----

    Health Status                 OK     N/A        N/A

    Media Wearout Indicator       0      0          0

    Write Error Count             N/A    N/A        N/A

    Read Error Count              120    50         120

    Power-on Hours                100    0          100

    Power Cycle Count             100    0          100

    Reallocated Sector Count      100    3          100

    Raw Read Error Rate           120    50         120

    Drive Temperature             29     0          31

    Driver Rated Max Temperature  N/A    N/A        N/A

    Write Sectors TOT Count       N/A    N/A        N/A

    Read Sectors TOT Count        N/A    N/A        N/A

    Initial Bad Block Count       N/A    N/A        N/A

    But it's not outputting the raw column. Compare this to this output (from a linux machine):-

    ID# ATTRIBUTE_NAME      FLAG VALUE WORST THRESH TYPE  UPDATED  WHEN_FAILED RAW_VALUE
      5 Reallocated_Sector_Ct   0x0033   100   100   010Pre-fail  Always   -   0
      9 Power_On_Hours      0x0032   099   099   000Old_age   Always   -   555

    187 Uncorrectable_Error_Cnt 0x0032   100   100   000Old_age   Always   -   0
    190 Airflow_Temperature_Cel 0x0032   070   060   000Old_age   Always   -   30
    195 ECC_Error_Rate      0x001a   200   200   000Old_age   Always   -   0
    199 CRC_Error_Count     0x003e   100   100   000Old_age   Always   -   0
    235 POR_Recovery_Count  0x0012   099   099   000Old_age   Always   -   3
    241 Total_LBAs_Written  0x0032   099   099   000Old_age   Always   -   417059068

    The raw column gives much more useful info that can be compared/monitored/graphed over time.

    Any ideas?
