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.
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.
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 FullIf you are using Server Manager, restart Server Manager after you update the cache by using this cmdlet.
