SMART Status not supported: Incomplete response, ATA output registers missing (CCISS)

[fereshtehloghmani]

hello
I user server HP (DL360 G8) and raid controller p420i.
I install smart on this server and I have some SATA and SSD hards that all of them are in a raid.
when i use these command like:
smartctl -a -d cciss,0 /dev/sg1
smartctl -a -d cciss,0 /dev/sda

i receive this error:
SMART Status not supported: Incomplete response, ATA output registers missing

could you please help me with how can I monitor all kinds of hard in G8 and G7 HP servers? and is this problem related to the type of raid controller or type of server or something like this?

thanks in advance

This is likely a bug or limitation of the SATL (SCSI/ATA Translation Layer) in controller driver or firmware.

For further diagnostics, please provide output of

smartctl -r ioctl,2 -H -d cciss,0 /dev/sg1

as an attachment to this ticket. Do not use screenshots, redirect smartctl output to a file and attach this file instead.

hello again
thank you for your response and here I provided the output of this command in the attachment.(attachment: out.txt)

Hello
I take another test on G8 and G9 hp server but this time with hp sas hard.
In this case when i run command:
smartctl -a -d cciss,0 /dev/sda
i didnt receive the error that i mention in firt ticket.
Now could you please help me is the that error related to SSD hard(in my firt test my hard was ssd evo 850 samsung) it means is it related to type of hard like ssd or sata hards? Or is my hard has a problem?

SMART Status not supported: Incomplete response, ATA output registers missing

This means that the SATL (SCSI/ATA Translation Layer) does not return ATA output registers properly. The SAT standards require that the ATA PASSTHROUGH SCSI commands return these registers in SCSI sense data if requested. This is not properly implemented here.

This is a typical limitation or bug in controller driver or firmware. This does not indicate disk problems.

If this occurs, smartctl check the attributes instead, which results in this output:

SMART overall-health self-assessment test result: PASSED
Warning: This result is based on an Attribute check.

SAS disks are not affected by this bug, because ATA PASSTHROUGH is not used.

This is a bug in controller driver or firmware. Cannot be fixed by smartctl.
