I have one disk in my cluster that is showing as a Local disk in Explorer. Strangely DISKPART shows this disk and all of the others as Clustered when I run DETAIL DISK. This disk is being used by the cluster (it's a SQL Server instance). I also compared permissions to another disk that is correctly marked as Clustered and they are identical. Any ideas what might be causing the problem? I have not tried failing over--this is a heavily used production system and failovers are difficult to schedule, so my troubleshooting options are limited.
Output from DISKPART (disk 14 (S:) is the disk displaying as Local, disk 15 (T:) is displaying correctly):
