[b]Description:[/b] 
I tested to spin down my unused disks with the green button on [Main] page and then later I started the disk with the same button (now unlit). 
After this was done I cannot run any SMART self-tests and cannot see the test results on the disk. The following is displayed:
[See attached image].. "Unavailable - disk must be spun up" ..

I have tried the [Spin Up] button too but no difference. Still same problem. 

I have tried a reboot and also power down of the unRAID server but problem is still there (Unavailable - disk must be spun up). 

Is there any way to solve this problem to have the disks available for SMART tests again? 

I can store information on the disks and also access information from them, so they are actually spun up already... 

I can also see SMART information from the disks.. 

 

Here is the disk information for the two disks that has this problem:

Your Main page doesn't look right at all. It is missing all images. Try to start your system in safe mode and see if this makes a difference. If not, post your diagnostics.

It's a copy/paste of the main page.. hold on, ill make a screenshot and also attach diagnostics.. give me a minute or two  

When you press the button "Spin Up" it should make the disk active. Does that happen?

Nope, that does not work. I have both tried the "Spin Up" button and also the grey button on main page.. The button on the main page goes green but i still see the message "Unavailable - disk must be spun up" and the SMART tests are unavailable...

 

 

What is the output of these commands:

 

hdparm -C /dev/sdb

hdparm -C /dev/sdc

 

root@Tower:~# hdparm -C /dev/sdb

/dev/sdb:
 drive state is:  idle

 

root@Tower:~# hdparm -C /dev/sdc

/dev/sdc:
 drive state is:  idle

 

Does the state change after:

 

hdparm -y /dev/sdb

hdparm -y /dev/sdc

Yes it does.

 

Drives changes from idle -> standby when checking with hdparm -C

 

root@Tower:~# hdparm -C /dev/sdb

/dev/sdb:
 drive state is:  standby

 

root@Tower:~# hdparm -C /dev/sdc

/dev/sdc:
 drive state is:  standby
 

But in the web interface of unRAID i cannot see any difference.. Except when i click a disk on mainpage to see the SMART attributes and the "Spin Up" button. The SMART attribues takes 2 seconds to load (probably because the disk have to spin up again)...

Another thing that is strange.. The other "working disks" (where I can start a SMART self test) they have the status: [active/idle] .. But the two disks that SMART test is unavailable have the status [idle] .... 

 

What is the difference between [active/idle] and [idle]? 

 

[Parity Disk]

root@Tower:~# hdparm -C /dev/sdg

/dev/sdg:
 drive state is:  active/idle

 

[Disk 1]
root@Tower:~# hdparm -C /dev/sde

/dev/sde:
 drive state is:  active/idle

 

[Disk 2]
root@Tower:~# hdparm -C /dev/sdf

/dev/sdf:
 drive state is:  active/idle

 

[Disk 3]
root@Tower:~# hdparm -C /dev/sdd

/dev/sdd:
 drive state is:  active/idle

 

[Disk 4]
root@Tower:~# hdparm -C /dev/sdb

/dev/sdb:
 drive state is:  idle

 

[Disk 5]
root@Tower:~# hdparm -C /dev/sdc

/dev/sdc:
 drive state is:  idle

 

This is from hdparm documentation:

 

-C : Check the current IDE power mode status, which will always be one of unknown (drive does not support this command), active/idle (normal operation), standby (low power mode, drive has spun down), or sleeping (lowest power mode, drive is completely shut down)

 

The state idle should not occur when a disk is active, according to hdparm. Not sure why this is happening. It does explain why the GUI doesn't work: it is looking for the word "active".

 

Ok this is strange... Explains why.. BUT.. From the beginning when i installed unRAID i was able to access the SMART test. Because i did ran a test on all disks.. So it has been working but is not working since i used the green button in [Main] window to spin the disks down since they were not going to be used for a while. After i did that the problem started with accessing the SMART buttons... 

 

Spinning down the array from the Main page can't be the cause for different behavior. I can't explain though.

 

Perhaps try unRAID 6.4 and see if that makes a difference.

Could it be the version and FW of the hard disks creating this problem maybe? Since the problem is not occurring for the other disks... 

 

Instead of trying a next release on my production stuff i will put in another disk of the same brand and see if that creates the same SMART problem, then i will install unRAID on another server and try the next release there to see if that fixes the issue. It will take me a month to fix this though...

 

This issue is not that serious though, but it is annoying.. I can still access the SMART information and that is important to be able to catch errors happening... But i cannot run any SMART self-tests though.. witch might be a problem... 

Was this ever resolved? I'm seeing the same phenomena, on all my array drives (WD SE 4TBs). 

Clicking "spin up" does spin the disk up, it moves to "standby" (a-la hdparm) and green ball, but the SMART buttons are still greyed out and "Unavailable - disk must be spun up". The one button that's functional is the Download button and it works - downloads a perfectly valid SMART report.

 

Any help would be appreciated.

When looking into this I can see:

> smartctl -x /dev/sdh | grep "^Device State:" | sed "s/^.*: *// ; s/ *(.*//"

Active

Whereas 

> hdparm -C /dev/sdh

/dev/sdh:
 drive state is:  standby

@bonienl - this may shed light onto what's going on. hdparm seems to not report the correct state.
