The disks in the screen shot and the photo do not match. Any suggestions on what might be wrong?
Have you check this post: 45Drives Tools: dalias - Error Duplicate Device Path Found Ignoring - #18 by Krushal
There is a script that should recognize which drive is in the slot.
The disk order is updated during a boot up.
Hope this helps you.
Hi @igor14051, It looks like the cabling of the system and our aliasing tool are backwards.
As @pcHome suggested you can run the script to realias the system for the wiring or if you would like you can swap the cables plugged into the motherboard which should also fix the issue
There should be 4 connectors total (2 different types), all you need to do is switch the pairs of cables in the system and then the drives should show up correctly

When you have a working HL15 (or other system), where the alias of 1-1 thru 1-x is shown in the houston UI, a drive needing to be replaced may not have the right alias.
While dalias is a great tool, the process is going to force you to remove the drive and replace it. It may or may not cause resilvering again.
I found the python script for dalias is great for the initial setup and in my case, I needed to fix

I wanted to have slot 1-9 and 1-10 back as the houston UI’s zfs module will not know the status of these two drives (/dev/sdi and /dev/sdj).
If you have /etc/vdev_id.conf with the right content (example from my hl15):
# This file was generated using dalias (2.0.0)
alias 1-1 /dev/disk/by-path/pci-0000:00:17.0-ata-1
alias 1-2 /dev/disk/by-path/pci-0000:00:17.0-ata-2

Then you can do a simple zpool export
remove the /etc/zfs/zpool.cache
then use zpool import -d /dev/disk/by-vdev MyPool
everything will be back to how the HL15 was originally configured (using the slots)
zpool status
pool: MyPool
state: ONLINE

Hope this is helpful. For me this saved me from having to remove/insert each drive.
I am working on a minor python script to run a series of commands to stop the needed services, unmount the needed disks, to then export the Pool, remove the zpool cache files, run a few udevadm commands, zpool import the pool, start all the services backup, etc
