I have an Dell PowerEdge R720xd.

I've been running on an H310 Mini Mono in Non-RAID mode. I just picked up one of the H310 Mini Mono's in IT mode from ArtOfServer.

After plugging in the new controller, I checked in the RAID BIOS to make sure all my disks were seen. They were so I proceeded to boot into Unraid.

It failed to start. I have 2 "missing disks" as well as the Cache missing.

I can add the cache drive back and its happy, but when I add the other two missing disks it says they're wrong even though their SN's match the missing disk info. It looks like a GUID or some kind of ID number is missing.

Not sure what to do. I do notice that the drive letters ie. sdb, sdc, etc are different than with the other controller.

Do I need to put the old controller back in, identify which disk is associated with its letter or path? Then put the new controller back in and do a new config on the array and redo parity?

 

Edit: Added diags with IT Mode H310 mini installed.

For Unraid this:

HITACHI_HUA723020ALA640_YFJ7HEWA

is not the same disk as

HITACHI_HUA72302_YFJ7HEWA_35000cca223df9798

 

One of the problems with using RAID controllers, you can do a new config and trust parity to accept the new identifiers.

Thats what I thought I needed to do, but I wanted to confirm so I didn't kill my server.

 

Its all up and running.

 

Thanks!
