Dell/NetApp SAS Hard Drive Not Assignable

[koshia]

Hello all.  I'm very green to UnRaid - finally got it up and running two days ago, after a few weeks of troubleshooting. Most of my drives are detected now and came up just fine.  There's a few that i'm having issues with and would like anyone's feedback if they now why or suggest things I can do to get it working.

 

Issue with Dell Drive: ST32000444SS // 2tb // sas

This drive came on and was assignable during my troubleshooting of the server.  At one point, I had accidentally hit the spin down button and since then, it's won't come back up.  Even after initiating a new parity and placing the drive in different bays.  I had even restored the USB drive and redid unRAID from scratch.  Nothing seems to get it back up.

 

Issue with NetApp Drive: X411_HVIPC420A15 // 450GB 15k // sas

While I understand that NetApp and EMC has proprietary firmware on their controllers that read these specially formatted drives at 520/528 blocks - I found an article that if you use sg_format, you could potentially get the drive reformatted to 512 and be able to use it.

 

My UnRaid setup detects these drives and I was able to get sg_format installed on unRAID and had formatted the drives to 512, but I cannot seem to assign them to anything. 

 

The symptoms are the same for both types of drives in the assignable storage locations and cache location.  If I select it in the storage location, the page refreshes and the sd? does not get assigned.

 

If I assign it to the cached area, the page refreshes and a message "no device" appears in the slots.

 

----diagnostics log--

I'm on Stable 6.2 - I tried to get a diagnostics log generated/exported but it doesn't look like it is working. The loading icon comes up in the browser, the page refreshes and the message about log generation disappears.

 

Alternatively, this is from the WebGUI Log
