Missing Disks after Firmware Update/USB Key Restore

[ThisGuyRightHere]

I am running UnRaid on an older IBM server (x3650 M4) that I recently picked up and the firmware hadn't been updated in a significant amount of time (3-4 years).  I successfully updated the firmware (IMM2, UEFI, DSA) but due to an issue I hit during this, I had to recreate my USB key.  Thankfully I had backed it up before starting, but now when I boot up UnRaid it shows all my disks as missing.  I have 4 in total (cache, parity, and 2 data disks).  All of them are listed as missing, but there's a drop down under each where it shows the disks that are in the system.  It looks like the disk names are slightly different now (there's additional characters after the original name).  I tried selecting the disks that should be for each drive location but it always says 'Wrong Disk'.  Not sure where I should start with this.  Any suggestions are greatly appreciated.

You will have to New Config to get it to accept the "new" disk assignments. Be very sure you don't accidentally assign a data disk to the parity slot. You can check the box to tell it to trust parity.

So I should just format the usb drive and start with a fresh install, or is there some option to set it to 'New Config'?  If I have to format the usb drive, will I be able to recover my VMs/Dockers?  Thanks for your reply.

Tools -> New config.

Sorry, just found that in the manual.  RTFM FTW   I'll give it a try tonight.  Thanks.

Alright, back up and running.  I really appreciate the quick responses!  For anyone that may stumble across this, I used the methods described here to determine which drive was the parity disk:

Read it carefully and double check what drives you choose!
