Effective and Efficient Ways to Recover Database in Suspect Mode

If you are a user of an SQL server, then you may encounter this issue. Sometimes we may find that a database is marked as a suspect when we attempt to connect to a SQL server, prohibiting us from accessing our database. 

In this article, I've covered two ways to recover SQL database in suspect mode. The first is the manual method, and the second is the use of the SQL Database Recovery Tool. It also highlights the various reasons why SQL databases are in suspect mode.

What is a Suspect Mode in MS SQL Server?

When your database server is in suspect mode, it has gotten corrupted or damaged. In this situation, neither you nor the server can access the SQL database while it is starting up. You must fix the damaged or corrupted files in order to resolve the suspicious mode problem.

In addition to all of this, SQL Server suspect mode may occur for a number of reasons. Look at the main causes of the SQL database (dB) being labeled as SUSPECT when the user encounters it. You may recover the MS SQL Database from Suspect Mode using the technique found here.

Reasons for Database Suspect Mode in SQL Server

There are multiple reasons why suspect mode in SQL servers happens. Here are some of the main causes behind this:-

●    Insufficient Disc Space

●    The system did not open data or log files on the device.

●    The installed antivirus cannot access data or log files while coming online.

●    An incorrect shutdown of the SQL database server.

●    A sudden Power Outage leads to the database in suspect mode.

●    Files in databases are stored by the operating system, third-party backup software, etc.

●    Sometimes, the SQL server crashes, leading to SQL data corruption.

Manual Methods to Recover Database in Suspect Mode

Follow the steps mentioned below to recover the SQL database in suspect mode.

Step 1: Set Suspect Database to EMERGENCY Mode

●    Launch SQL Server Management Studio, Connect the database, and choose the new query. After then, turn off the suspect mode and switch the database to emergency mode.

●    EXEC sp_db_name SET EMERGENCY

●    ALTER DATABASE db_name SET EMERGENCY

Step 2: Identify Database Damage

Apply a Consistency Check on the master file. Its main function is to locate any logical and physical errors in the database.

DBCC CHECKDB ( Database name)

Step: 3 Run Repair Command to Recover SQL Database from Suspect Mode

Run the next SSMS query after that. Despite this, there may be some data loss as a result of this query.

DBCC CHECKDB (N’Database_Name’, REPAIR_ALLOW_DATA_LOSS) WITH ALL_ERRORMSGS, NO_INFOMSGS;

Step 4: Return to multi-user mode

Now you can switch from the Single-user mode to multi-user mode and also check the data connectivity.

ALTER DATABASE dbName SET MULTI_USER

Following the above-mentioned procedures, you can successfully recover the database in suspect mode.  But if your SQL server is severely corrupted, then the manual process is inappropriate.  In that situation, we advise selecting the  Microsoft SQL Repair Tool. This tool is the ideal solution for fixing and recovering all of the NDF and MDF files for faulty SQL databases.
