Note:
After the mainstream SSD reaches the limit for the number of write operations that are
supported, write operations to the SSD become slower over time, and at some point the SSD becomes
a read-only drive. To support normal write operations, the drive must be replaced. Replacement of the
mainstream SSD might not be covered by the system's level of service entitlement, depending on the
terms and conditions of the system. For more information about mainstream SSDs, see “Mainstream
solid-state drives” on page 108. This ends the procedure.
Using the Linux fuel gauge command
Learn how to use the Linux operating system fuel gauge command to find the amount of remaining life
in a mainstream solid-state drive (SSD).
To use the fuel gauge tool for the Linux operating system, complete the following steps:
1.
If the system has logical partitions, complete this procedure from the logical partition that reported
the problem.
2.
Choose from the following options:
v
To use the
iprconfig
command, continue with step 3.
v
To use the
ssd-report
command in the
iprutils
command-line interface, continue with step 9.
3.
In the command line, enter the following command:
$ iprconfig
4.
In the main menu, select the Devices Statistics option.
5.
In the Device selection screen, select Read Intensive SSD (Mainstream SSD) by moving the cursor to
the correct line and pressing 1.
6.
Press Enter to confirm. The statistics for the selected device is shown.
7.
Review the information in the first block of information.
8.
Continue with step 10.
9.
To use the
ssd-report
command in the
iprutils
command-line interface, complete the following
steps:
a.
Type
$ iprconfig -c ssd-report <dev>
Where <dev> is the device you want to use.
b.
Review the information that is shown.
c.
Continue with step 10.
10.
Interpret the statistics:
v
Total Bytes Written: Number of GB already written to the device
v
Number of Bytes reported by Warranty: Number of GBs that can be written according to the
specification
v
Life Remaining Gauge: An estimate of how much of the device's life has been consumed
v
PFA Trip: The device has detected an issue that could lead to a failure
v
Power-on Days: Number of days since the last power-on
11.
Is the value in the Life Remaining Gauge field less than or equal to 2 percent?
v
Yes
: Continue with the next step.
v
No
: The mainstream SSD is not reporting a change in status for the number of write operations
available.
12.
Is the value in the Life Remaining Gauge field 0 percent?
v
Yes
: Continue with step 13.
v
No
: Continue with step 14 on page 113.

The mainstream SSD reached the limit for the number of write operations that are supported. Write
operations to the SSD become slower over time, and at some point the SSD becomes a read-only
drive. When the operating system writes to the read-only drive, the write operations are rejected,
and the operating system considers the drive as if a failure occurred. For example, if the operating
