Table 6. Physical Device Properties (continued)
Properties Description
spare sectors are less than 10 percent of the original pool, the
drive enters read-only mode.
Possible values for the device life status are:
Drive Health Good — The drive is used within the TBW
specification. The drive health is good as sufficient spare
blocks are available. The drive health status is good if the
values for percent lifetime used and write protect progress is
less than 100 percent.
Approaching Warranty Coverage Expiry — The drive is
reaching the specified TBW, indicating that it is close to
the end of warranty coverage. However, the drive will be
functional as the number of spare blocks available are still
above the threshold for entering the read-only mode. The
drive approaches the warranty coverage expiry if the value for
percent lifetime used is greater than or equal to 90 percent
and that for write protect progress is less than the threshold
value, which is 90 percent.
Warranty Coverage Expired — The drive has reached the
TBW threshold and met the life expectancy specification. The
drive is functional as the number of spare blocks available are
still above the threshold for entering the read-only mode. But,
the specified data retention period (amount of time that data
can be read from the drive after TBW is reached) drops, if
TBW specification is exceeded and the warranty for the drive
expires. The warranty coverage for the drive expires if the
value for percent lifetime used is equal to 100 percent and
that for write protect progress is less than 100 percent.
Approaching Read Only — The drive is running out of spare
sectors and is reaching the read-only mode. However, the
health status of the drive is good and data retention is
unaffected. The drive is stated to be approaching the read-
only mode if the value for percent lifetime used is less than
100 percent and that for write protect progress is greater
than or equal to 90 percent.
Read Only — The drive is in read-only mode. Users must save
open files, if any, to another device and replace or remove the
device. If this scenario occurs within three years of the device
installation, this failure is covered under warranty. The drive is
in read-only mode if the value for percent lifetime used is less
than 100 percent and that for write protect progress is equal
to 90 percent.
Driver Version
Displays the version of the driver that is installed on the PCIe
SSD sub-system.
NOTE: Storage Management displays Not Applicable
for subsystem for which the driver version cannot be
obtained.
Remaining Rated Write Endurance
Displays information on the SSD renewal/replacement based
on the amount of write workloads. This field indicates the
total remaining programs or erase-cycles available on the SSD,
based on the cumulative specification of the total NAND
(Negated AND or NOT AND) Flash chips in the SSD.
NOTE: This option is applicable to Micron PCIe SSDs,
Non-Volatile Memory Express (NVMe) PCIe SSDs, and
SAS/SATA SSDs.
