My unraid server was connected to a disk shelf (NETAPP DS4246) that contained all my pool devices, the shelf has suffered a failure and will take a number of weeks while I wait for new parts to be delivered.
My Pool Devices (My SSD drives, 6x1tb) were not in the shelf but directly connected to the server.

My 3tb SSD pool contains the appdata folder and all the docker files are on that SSD. Almost all my docker containers were only reading/writing to the SSD's (with the exception of Jellyfin and maybe some apps that end in arr).
Is there are I can start most of my docker services to get things partially back online while I wait for the spare parts to arrive. As far as I can tell all the Hard Drives are healthy, so as soon as my new disk shelf arrives I would be re-adding all the array drives.

I have a feeling I new to create a new config, if that's the case, do I just need to note what drives were in what slot or do I just need to note which 2 drives were my parity drives?
I have my Unraid install on a Samsung Bar 128gb flash drive, I have a brand new one (unopened) would it be better copy the contents onto the 2nd flash drive as a backup before messing with my config? I assume It's just copying and pasting the files or should I use some cloning software?

Part 2 of this question is restoring my server once I get my new disk shelf. I will be using the same LSI RAID card, but I will have an entirely new shelf (I opted to go new shelf for faster SAS link to the shelf). While the server was in a failing state it only marked parity 2 and disk 3 as failed (the other were spun down). When I rebooted the server all the disks were missing. Parity 2 and Disk 3 do not have the drive serial numbers written under them, all the other disks do both of these drives are Seagate EXOS 18tb SATA drives. I am a little concerned as the disk shelf lit up the drives with 2 drives with an orange light but this was prior to the reboot. (I have 2 Parity + 12 Array, all SATA, mostly Seagate EXOS)

I am also worried about some custom stuff I have running, for things like IPMI control of the server fans. The fans spin at full speed (Lenovo SR650, I think 16,000rpm 2ru) and I use IPMI to spin them down to like 4000rpm. From memory this was something custom I had to download and load into a specific folder on the flash drive and I can't remember how I did it.

Just looking for some advice to the steps I need to take for partial restoration and then what steps to take once I get my new disk shelf.

Yes, you can do a new config with the remaining devices, then add them back the same as they were.
