Description

Fix SSD health percentage issue for vendor Virtium device VSFDM8XC240G-V11-T
This is to backport #407 to 202305 branch

Motivation and Context

The SSD health percentage is calculated using 100 * (1 - NAND_endurance / Average_Erase_Count) or Remaining Life Left if either of the attributes is undefined.
On this device, NAND endurance is not defined, and Remaining Life Left is not recognized by SmartCmd or smartctl. We have to parse the health percentage using the ID of Remaining Life Left which is 231 according to the vendor.

How Has This Been Tested?

Unit test and manually test on different Virtium devices (VSFDM8XC240G-V11-T and StorFly VSF302XC016G-MLX1
