Troubleshoot AlwaysOn availability databases in Recovery Pending or Suspect state in SQL Server
This article describes the errors and limitations of an availability database in Microsoft SQL Server that is in a Recovery Pending or Suspect state and how to restore the database to full functionality in an availability group.
Original product version: В SQL Server 2012
Original KB number: В 2857849
Summary
Assume that an availability database that is defined in an AlwaysOn availability group transitions to a Recovery Pending or Suspect state in SQL Server. If this occurs on the availability group’s primary replica, database availability is affected. In this situation, you can not access the database through the client applications. Additionally, you can not drop or remove the database from the availability group.
For example, assume SQL Server is running and an availability database is set to the Recovery Pending or Suspect state. When you query the dynamic management views (DMVs) at the primary replica by using the following SQL script, the database might be reported in a NOT_HEALTHY and RECOVERY_PENDING state or in a SUSPECT state as follows:
Additionally, this database may be reported as being in the Not Synchronizing / Recovery Pending or Suspect state in SQL Server Management Studio.
When the database is defined in an availability group, the database can not be dropped or restored. Therefore, you have to take specific steps to recover the database and return it to production use.
More information
The following content discusses the errors and limitations of an availability database that is in a Recovery Pending state in various situations.
Database status prevents restoring database
You try to run the following SQL script in order to restore the database that has the RECOVERY parameter:
When you run this script, you receive the following error message because the database is defined in an availability group:
Msg 3104, Level 16, State 1, Line 1
RESTORE cannot operate on database DatabaseName because it is configured for database mirroring or has joined an availability group. If you intend to restore the database, use ALTER DATABASE to remove mirroring or to remove the database from its availability group.
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.
Database status prevents dropping database
You try to run the following SQL script in order to drop the database:
When you run this script, you receive the following error message because the database is defined in an availability group:
Msg 3752, Level 16, State 1, Line 1
The database DatabaseName is currently joined to an availability group. Before you can drop the database, you need to remove it from the availability group.
Database status prevents removing database from availability group
You try to run the following SQL script to remove the database from the availability group:
When you try to run this script, you receive the following error message because the availability database belongs to the primary replica:
Msg 35240, Level 16, State 14, Line 1
Database DatabaseName cannot be joined to or unjoined from availability group AvailabilityGroupName. This operation is not supported on the primary replica of the availability group.
Because of this error message, you may be compelled to fail over the database. After the database is failed over, the replica that owns the recovery pending database is in the secondary role. In this situation, you try to execute the following SQL script again in order to remove the database from the availability group at the secondary replica:
However, you still can not remove the database from the availability group, and you receive the following error message because the database is still in Recovery Pending state:
Msg 921, Level 16, State 112, Line 1
Database DatabaseName has not been recovered yet. Wait and try again.
Resolution when the database is in the secondary role
To resolve this issue, take the following general actions:
To take these actions, connect to the new primary replica, and then run the ALTER AVAILABILITY GROUP SQL script to remove the replica that is hosting the failed availability database. To do this, follow these steps.
These steps assume that the primary replica first hosts the damaged database. Therefore, a failover must first occur to transition the replica that is hosting the damaged database into a secondary role.
Connect to the server that is running SQL Server and that is hosting the secondary replica.
Run the following SQL script:
Run the following SQL script to remove the replica that is hosting the damaged database from the availability group:
Resolve any issues on the server that is running SQL Server and that might contribute to the database failure.
Add the replica back into the availability group.
Resolution when the primary replica is the only replica in the availability group
If the primary replica hosts the damaged database and is the only working replica in the availability group, the availability group must be dropped. After the availability group is dropped, your database can be recovered from a backup, or other emergency recovery efforts can be applied to restore the databases and to resume production.
To drop the availability group, use the following SQL script :
At this point, you can try to recover the problematic database. Or you can restore the database from the last-known good backup copy.
Resolution when you drop the availability group
When you drop an availability group, the listener resource is also dropped and interrupts application connectivity to the availability databases.
To minimize application downtime, use one of the following methods to sustain application connectivity through the listener and drop the availability group:
Method 1: Associate the listener with a new availability group (role) in Failover Cluster Manager
This method lets you maintain the listener while dropping and re-creating the availability group
On the instance of SQL Server to which the existing availability group listener is directing connections, create a new, empty availability group. To simplify this process, use the Transact-SQL command to create an availability group that has no secondary replica or database:
Start Failover Cluster Manager, and then click Roles in the left pane. In the pane that lists the roles, select the original availability group.
In the bottom-middle pane under the Resources tab, right-click the availability group resource, and then click Properties. Click the Dependencies tab, delete the dependency to the listener, and then click OK.
Under the resources, right-click the listener, click More Actions, and then click Assign to Another Role.
In the Assign Source to Role dialog box, select the new availability group, and then click OK.
In the Roles pane, select the new availability group. In the bottom-middle pane, under the Resources tab, you should now see the new availability group and the listener resource. Right-click the new availability group resource, and then click Properties.
Click the Dependencies tab, select the listener resource from the drop-down box, and then click OK.
In SQL Server Management Studio, use Object Explorer to connect to the instance of SQL Server that hosts the primary replica of the new availability group. Click AlwaysOn High Availability, click the new availability group, and then click Availability Group Listeners. You should find the listener.
Right-click the listener, click Properties, type the appropriate port number for the listener, and then click OK.
This makes sure that applications that use the listener can still use it to connect to the instance of SQL Server that is hosting the production databases without interruption. The original availability group can now be completely removed and re-created. Or the databases and replicas can be added to the new availability group.
If you re-create the original availability group, you should reassign the listener back to the availability group role, set up the dependency between the new availability group resource and the listener, and then reassign the port to the listener. To do this, follow these steps:
Method 2: Associate the listener with an existing SQL Server Failover Clustered Instance (SQLFCI)
If you are hosting your availability group on a SQL Server Failover Clustered Instance (SQLFCI), you can associate the listener clustered resource with the SQLFCI clustered resource group while you drop and then re-create the availability group.
Start Failover Cluster Manager, and then click Roles in the left pane.
In the pane that lists the roles, select the original availability group.
In the bottom middle pane under the Resources tab, right-click the availability group resource, and then click Properties.
Click the Dependencies tab, delete the dependency to the listener, and then click OK.
In the bottom middle pane under the Resources tab, right-click the listener, click More Actions, and then click Assign to Another Role.
In the Assign Resource to Role dialog box, click the SQL Server FCI instance, and then click OK.
In the Roles pane, select the SQLFCI group. In the bottom middle pane, under the Resources tab, you should now see the new listener resource.
This makes sure that applications that use the listener can still use it to connect to the instance of SQL Server that hosts the production databases without interruption. The original availability group can now be removed and re-created. Or the databases and replicas can be added to the new availability group.
After the availability group is re-created, reassign the listener back to the availability group role. Then set up the dependency between the new availability group resource and the listener, and reassign the port to the listener:
Method 3: Drop the availability group, and then re-create the availability group and listener with the same listener name
This method will result in a small outage for applications that are currently connected because the availability group and listener are dropped and then re-created:
Drop the availability group.
This will also drop the listener.
Immediately create a new, empty availability group that includes the listener definition, on the same server that hosts the production databases.
For example, assume that your availability group listener is aglisten. The following Transact-SQL statement creates an availability group with no primary or secondary database, but it also creates a listener named aglisten. Applications can use this listener to connect.
Recover the damaged database. Then add it and the secondary replica back to the availability group.

Introduction
SQL Server is the backbone of organizations dealing with a large amount of data. However, DBAs may find a lot of difficulties while managing the SQL database. For example, SQL shows ‘Recovery Pending’ status for a database after a restore attempt fails. We will go through the reasons and ways to deal with this issue.
Why does SQL Server display the ‘Recovery Pending’ status?
The different SQL Database States
When the core files of the SQL database are damaged or corrupted, it leads to an inconsistent state. And, the severity of the damages is decided based on different states of the SQL database. Some of them are mentioned below:
How to change ‘Recovery Pending’ State in SQL Server?
You can resolve this error in two ways:
Method 1: Initiate Forceful Repair by Marking Database in Emergency Mode:
Before starting the repair, check the state of SQL database with the help of the following command
SELECT name, state_desc from sys.databases
GO
Now, execute the mentioned set of queries and you will be able to resolve the issue of Recovery Pending.
ALTER DATABASE [DBName] SET EMERGENCY;
GO
ALTER DATABASE [DBName] set single_user
GO
DBCC CHECKDB ([DBName], REPAIR_ALLOW_DATA_LOSS) WITH ALL_ERRORMSGS;
GO
ALTER DATABASE [DBName] set multi_user
GO
Method 2: Detach the Main Database and Reattach it after Marking Database in Emergency Mode:
Type the set of queries and execute them to solve the pending state error:
ALTER DATABASE [DBName] SET EMERGENCY;
ALTER DATABASE [DBName] set multi_user
EXEC sp_detach_db ‘[DBName]’
EXEC sp_attach_single_file_db @DBName = ‘[DBName]’, @physname = N'[mdf path]’
The above commands will free the server from the corrupt log and automatically start to build new logs.
Please Note:
Backup the SQL data before you try any of the above workarounds. Having a safe copy of data will never leave you empty-handed even if the procedure fails to execute correctly. The methods are highly technical and should be performed under the guidance of technical experts.
What to do when SQL data is inaccessible due to database corruption?
SQL data can be inaccessible due to SQL database corruption. You should avoid trying the manual SQL recovery methods if you’re not a technical expert.
