Database Is in a Clean Shutdown State

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime.

The Microsoft® Exchange Server Analyzer Tool has determined that your Exchange Database is in a Clean Shutdown state.

A database that is in a Clean Shutdown state has been shut down correctly and detached from the log file stream. As a result, if you want to mount the database again, you may do so with out performing any recovery operations.

If you cannot mount a database that is in a Clean Shutdown state, the reason is not because the database requires additional transaction log file replay. However, it is possible that transaction log replay required for other databases in the same storage group may prevent a Clean Shutdown database from mounting. Before any database in an Exchange storage group can be mounted, all databases in that storage group must be recovered and brought to a mountable state.

A database that is in a Clean Shutdown state can be mounted with its previous transaction logs or with a different set of transaction logs. If you mount a database that is in a Clean Shutdown state and no transaction logs exist, a new set of transaction logs will be generated.

Generally, you should not delete existing transaction log files, even if all databases in a storage group are in Clean Shutdown state. If you delete existing transaction log files, you will not be able to roll forward from previous backups. However, deleting transaction log files when all databases in a storage group are in a Clean Shutdown state does not affect the current databases. As a best practice, if you delete all transaction log files for a storage group, you should immediately create a full backup of all databases in the storage group.
