Smartmontools values are not get.(Debian)

[Nikolay-Gamzin]

Describe the bug
I need to write Python to help me monitor the S.M.A.R.T information on my SSD.
I found the tools developed by your team on the Internet and configured them. it doesn't seem to get the value right. So I hope you can help me.

Hi @Nikolay-Gamzin

Notice that your drive is handled as scsi instead of ata/sata: /dev/sda: Device of type 'scsi' [SCSI] detected

the field .attributes is only filled with ATA ATTRIBUTES.

I know it is a bit confusing and I'm working to provide a clearer way to get those attributes. For now it is what it is.

If you have the latest pystorcli version, the data you are searching for is under .diagnostics field. (that field is only filled with scsi data BTW).

Tell me if you find out any other issue or if I haven't fixed your problem.
Thanks for your interest

@ralequi Hi. pySMART version 1.2.3
But the disk is an SSD and the utility shows it correctly
sda.is_ssd
True
sda.interface
'sat'
But diagnostics is empty
sda.diags
{'Reallocated_Sector_Ct': '-', 'Start_Stop_Spec': '-', 'Start_Stop_Cycles': '-', 'Start_Stop_Pct_Left': '-', 'Load_Cycle_Spec': '-', 'Load_Cycle_Count': '-', 'Load_Cycle_Pct_Left': '-', 'Power_On_Hours': '-', 'Life_Left': '-', 'Corrected_Reads': '-', 'Corrected_Writes': '-', 'Corrected_Verifies': '-', 'Uncorrected_Reads': '-', 'Uncorrected_Writes': '-', 'Uncorrected_Verifies': '-', 'Reads_GB': '-', 'Writes_GB': '-', 'Verifies_GB': '-', 'Reads_count': '-', 'Writes_count': '-', 'Verifies_count': '-', 'block_size': '512', 'Non-Medium_Errors': '-'}

Sorry, miss read, let me check it further

[ralequi]

Ok, I can confirm there is a bug parsing the output of

smartctl -d test /dev/sda
smartctl 7.2 2020-12-30 r5155 [x86_64-linux-5.10.0-19-amd64] (local build)
Copyright (C) 2002-20, Bruce Allen, Christian Franke, [www.smartmontools.org](http://www.smartmontools.org/)

/dev/sda: Device of type 'scsi' [SCSI] detected
/dev/sda [SAT]: Device open changed type from 'scsi' to 'sat'
/dev/sda [SAT]: Device of type 'sat' [ATA] opened

Which is something different from the classic

smartctl 7.2 2021-01-17 r5171 [x86_64-linux-5.13.4-200.fc34.x86_64] (local build)
Copyright (C) 2002-20, Bruce Allen, Christian Franke, www.smartmontools.org

/dev/nvme0: Device of type 'nvme' [NVMe] detected
/dev/nvme0: Device of type 'nvme' [NVMe] opened

(notice there is no "error" detecting the type on the second output but there is on the first one)

[ralequi]

Another issue with your output is the ATA attribute format

SMART Attributes Data Structure revision number: 20 should be SMART Attributes Data Structure revision number: 1

That means this version is unsupported by pysmart, let me check how easy is to parse...

[ralequi]

Hi @Nikolay-Gamzin

Please, checkout the develop branch and tell me if the issue is still there.

You can try running pip install git+https://github.com/truenas/py-SMART.git@develop

If everything looks OK, I might launch release 1.2.4.

Thanks for your contribution!
