3.6.1 Monitoring the Status of M.2 Disks

You can monitor the status of a M.2 disk by checking its attributes with the CellCLI LIST PHYSICALDISK command.

The disk firmware maintains the error counters, and marks a drive with Predictive Failure when the disk is about to fail. The drive, not the cell software, determines if it needs replacement.

• Use the CellCLI command LIST PHSYICALDISK to determine the status of a M.2 disk:

  CellCLI> LIST PHYSICALDISK WHERE disktype='M2Disk' DETAIL
           name:                           M2_SYS_0
             deviceName:                  /dev/sdm

           status:                normal

  The Exadata Storage Server M.2 disk statuses are:

  • normal

  • not present

  • failed

  • warning - predictive failure
