I recently migrated my drives and Mobo into a Supermicro 4U case with BPN-SAS2-846EL2 backplane.  8 Disks were previously connected through HBA and breakout cables, with the remaining 3 on SATA.  On initial startup, the array hung when started.  Server was showing the 'array is starting' notification, docker and VMs hang, nothing happened when I clicked 'stop array.' 

 

Booted server in safe mode,  traced it to Unassigned Devices, and uninstalled, server functions normally.  I tried deleting the plugin folders from the config folder and reinstalling, reissuing UUID, and probably a couple of other things mentioned in threads and help.  After reinstalling plugin, the array mounts normally, but all array disks show up in UD, with greyed out Array bar, as well in the Array Devices list.  The array is functional, and docker and VM's load, but won't spin down with UD installed, and the log stops if I issue the stop array command. 

 

The issue seems to be that the sdx drive assignments are in disagreement between Unraid and UD.  I see reference to this in the instructions, but can't find any instruction on how to fix it.  I'm getting the same device id error on all of the backplane disks.

First turn off and stop vm/docker services. seting docker off, settigns vm off..

as this sounds like a existing disk confi issue... My recommendation is to go to tools > new config and preserver and pool device and reset up your d1, d2, party disk if any...

 

Could you clarify this a bit? I ran through a new config with preserve pool and array slots selected, and preserved parity, thinking maybe that would flush some sort of bad config setting, but no dice.  Are you saying I should rebuild parity?

This means that some devices are being detected twice, make sure you are not using two expanders on the same enclosure, Unraid does not support SAS multipath.
