Querying SSD Lifespans

Querying SSD Lifespans

Scenario

Query the lifespan of an SSD.

Procedure

  1. Log in to the OS as an administrator or a member in the administrator group.
  2. Run the following command to query the SMART information of the SSD controller (such as nvme0):

    hioadm info -d nvme0 –s

    The command output is similar to the following:

    [root@localhost tool]# hioadm info -d nvme0 -s  
    critical warning              : no warning 
    composite temperature         : 308 degrees Kelvin (35 degrees Celsius) 
    available spare               : 100% 
    available spare threshold     : 10% 
    percentage used               : 0% 
    data units read               : 68.8 MB 
    data units written            : 0.0 MB 
    host read commands            : 17748  
    host write commands           : 0  
    controller busy time          : 0 mins 
    power cycles                  : 89 times 
    power on hours                : 1164 h 
    unsafe shutdowns              : 35 times 
    media and data integrity errors: 0  
    number of error information log entries: 0  
    warning composite temperature time: 0 min 
    critical composite temperature time: 0 min 
    data status                   : OK
    

  3. The percentage used parameter displays the used lifespan percentage of the SSD.

    If the value of percentage used exceeds 100%, the SSD lifespan has expired, and Huawei's warranty service is unavailable. You need to back up data on the SSD as soon as possible and replace the SSD.
