Supermicro Megaraid 3108 drive marked as UB, windows bad config on boot? raid 6

[markm75]

I had a failing drive (in port 3) on the AOC-S3108L-H8iR card, so I put a brand new drive in its place. This is a raid 6 array of 8 drives, the OS was carved out of that.

I put the new drive in slot 3, it initially didn’t show as rebuilding, it was offline, so in the windows interface for this machine I did the option to bring online (it warned about bringing the drive online, i thought just a standard warning, i expected it to rebuild the array and be fine, but windows immediately bsod). Wondering if this broke the full array in some way, as now I get "bad system config info" bsod on booting windows server 2019.

So I booted up to the megaraid bios area. The "new" drive was marked UB, i tried to mark unconfg. good and now its foreign.


If i use a boot stick and boot to a command prompt i can actually see all the drive letters still there, so im not sure why windows is giving the bsod if the data is there. I just cant seem to figure out what to do to get the new drive detected correctly or mark it as hotspare (maybe i need to diskpart/clean it first)?

Im unsure if the OS/data in the raid 6 array are entirely corrupted nor can i seem to change the new drive to be a hotspare (and the old flaky drive now shows UB).

Anyone ran into this before?

Thanks for any suggestions

on reboot at the bios prompt it asked to import the foreign disk, doing this it now says rebuilding.

I don’t suppose I should have done this to the flaky dying drive instead (which was also marked ub)? At this point I guess too late since it says 2% rebuilding?
(when I use the boot stick to get into 2019 windows, the c:\windows\system32\config folder is blank (not a good sign)

After a chkdsk /f , the data on the c drive reappeared (config folder), it then restarted normally and is doing a windows update finalization, unreal, never seen this happen before.

The easiest thing to do is from the Drive Management screen, choose the new drive and make it a Hot Spare ( I believe that card calls it a Global HS) and since you only have a single array it should automatically start to rebuild the degraded array.
