Restrictions on dbcc checkstorage for Shared-Disk Clusters

Restrictions for using dbcc checkstorage on shared-disk clusters.

You cannot include instance-only named caches with dbcc checkstorage. dbcc checkstorage issues this error message if you do so:
```
The cache %1! cannot be used because it is an instance only cache
```
To run dbcc checkstorage against a local temporary database, you must run the command from the same instance that owns the local temporary database.
For performance reasons, dbcc checkstorage in the Cluster Edition may not query the latest version of a page in the cluster. This may cause the Cluster Edition to report more soft faults than other versions.

For well-partitioned applications where a single instance updates a database, dbcc checkstorage behaves as earlier non-Cluster Edition SAP ASE versions.
