Issue with my controllers and green drives

I suddenly had unraid v6.2.1 say 2 of my WD Greens are failing, but when checking SMART, I see no errors logged. It doesn't look like they are failing and preclear on them went fine a few days prior. The errors logged on the webui main tab happened when copying data to them.

You can see what the 2TB HDDs show as here:

This is a small snippet from the system log:

[Mon Nov  7 15:56:08 2016] program smartctl is using a deprecated SCSI ioctl, please convert it to SG_IO

To check the errors were not coming from unraid, I tried this command and got the following:

watch -n 5 "dmesg -T| tail -n $((LINES-6))"

The last line gets repeated over and over, so this is only a snippet.

I have since reset the server as when trying to stop the array, the webgui locked up and could not kill and restart it. The HDDs still came up with the red x.

Now both those drives are on my RocketRaid r750 controller on the same port multiplier channel.

I also have a 3ware 9650SE-8LPML controller as well. No drives in the pool are on it yet though.

I have many more EADS and EARS green HDDS still to add. All my drives have been set to never spin down, and unraid is also set to never spin them down. I do notice for some reason, unraid is still spinning them down as if I try to access them after awhile of inactivity, they take about 15 seconds to respond. I recently came from FlexRaid and never had this initial sluggishness with these green drives as I do now.

I'm not sure if there is an issue with the driver used for my controllers and/or with WD Green drives in general on unraid. But not sure what to do next.

I noticed one other oddity, when hovering over the X, it says the drives were being emulated, but I have not even computed parity yet, so not sure how it could emulate them. This seems like a bug.

So I was able to get rid of these errors:

3w-9xxx: scsi1: ERROR: (0x03:0x010D): Invalid field in CDB:.

All I did was move the one drive on that controller onto my r750. The 3ware bios no longer gets installed on boot because no drives are attached to it. So I take it the error is related to the controller and not any issues with the drive. Just sucks if I use that controller, I'll have that error flood my log and don't know how to fix it.

My log is still constantly flooded with these though:

Nov 9 05:06:02 Storinator kernel: program smartctl is using a deprecated SCSI ioctl, please convert it to SG_IO

I still have yet to figure out the issue with my WD Green drives.

See here.

See this post regarding the 3ware 9650: https://lime-technology.com/forum/index.php?topic=38245.msg354467#msg354467. It was posted nearly two years ago so the situation might have changed since then. There are other HBAs that are supported by unRAID - you should have asked first

yeah but these cards are pretty good value, wish they could work as well... 

Not sure if you already know this, but even if you get your hardware problems cleared up you must rebuild those drives before unRAID will use them again.

What do I do if I get a red X next to a hard disk?
