Upgrade to Server 2019 storage spaces problem - not migrated due to partial or ambiguous match

Steel Contributor

I upgraded a server from 2016 to 2019. After the upgrade one of my Storage Spaces drives went missing. The drives are showing in Device Manger but aren't showing Disk Management and the Storage Pool is gone. At first I thought the problem was a cheap controller (4 Port SATA in home test server) wasn't being supported in Server 2019. I swapped out with a LSI SATA / SAS card that has certified drivers. Still having same problem. All 4 disks are showing this error in device manager:

Device SCSI\Disk&Ven_ATA&Prod_INTEL_SSDSA2MH08\5&10774fde&0&000400 was not migrated due to partial or ambiguous match.

Last Device Instance Id: SCSI\Disk&Ven_Msft&Prod_Virtual_Disk\2&1f4adffe&0&000003
Class Guid: {4d36e967-e325-11ce-bfc1-08002be10318}

Status: 0xC0000719


This doesn't seem to directly be Storage Spaces issue but since they were that way in 2016 I figure it might be related. Anyone have any suggestions?

One other thing I found is disks are listed as Starting?
