Hello,

 

I have a bunch of SAS SSDs that currently only display drive temperature information in the SMART Attributes tab.

The SSDs in question are: Toshiba PX04SVB096 and PX04SRB096, but I assume this applies to other SAS SSDs as well.

 

It would be really nice if we could also see the 'Percentage used endurance indicator'.

 

This value is available as `Percentage used endurance indicator: xx%` through either of these commands: 

smartctl -a /dev/xxx
smartctl -l ssd /dev/xxx

Or, as `"scsi_percentage_used_endurance_indicator"= xx` though the JSON command:

smartctl -a -j /dev/xxx

 

Examples:

> smartctl -a /dev/xxx

...
=== START OF READ SMART DATA SECTION ===
SMART Health Status: OK

Percentage used endurance indicator: 10%
...

> smartctl -l ssd /dev/xxx

...
=== START OF READ SMART DATA SECTION ===
Percentage used endurance indicator: 10%

> smartctl -a -j /dev/xxx

...
  "smart_status": {
    "passed": true
  },
  "scsi_percentage_used_endurance_indicator": 10,
  "temperature": {
    "current": 25,
    "drive_trip": 64
  },
...

 

I also noticed that SAS SSDs or HDDs that show 'Accumulated power on time, hours' incorrectly show 'minutes xxxxxx' instead of 'hours xxxxxx' or just 'xxxxxx'.

 

Example: 

 

Raw data:

> smartctrl -a /dev/xxx

...
=== START OF READ SMART DATA SECTION ===
SMART Health Status: OK

Percentage used endurance indicator: 22%
Current Drive Temperature:     31 C
Drive Trip Temperature:        64 C

Accumulated power on time, hours:minutes 27404:25
...

 

27404 is the number of hours, not minutes.  Not sure if it is scrapping the value wrong, or just displaying it weirdly.

I've submitted a PR to fix this issue: https://github.com/unraid/webgui/pull/1550

 

I'll try and work on another one for my original enhancement suggestion.

Ok, I've submitted a PR for this 'enhancement' as well: https://github.com/unraid/webgui/pull/1551

 

My PRs got merged, so it looks like these bug fixes / enhancements will be part of the next release (whenever that is).
