You cannot manage newly added disks by using Storage Spaces on Windows Server 2012 or Windows Server 2012 R2

Applies to: Windows Server 2012 R2 DatacenterWindows Server 2012 R2 EssentialsWindows Server 2012 R2 Standard

Symptoms


Assume that you are using Storage Spaces in Windows Server 2012 or Windows Server 2012 R2. You hot-add a disk or you remove a disk from an enclosure that is managed by Storage Spaces. In this situation, you may encounter the following issues:
  • You cannot retrieve the slot or enclosure number of the disk.
  • You cannot control the failure or identity LED of the disk.

Cause


This issue occurs because Storage Spaces is not aware of changes (such as hot-added disks) that are made to the physical storage device after it is started.

Workaround


To work around this issue, run the following Windows PowerShell cmdlet after any physical changes are made to the storage device in order to update the cache:
Update-StorageProviderCache -DiscoveryLevel Full 
If you are using Server Manager, restart Server Manager after you update the cache by using this cmdlet.
