# Resetting Maintenance Failovers in a Linux Environment

After performing the necessary maintenance activity on the production CommServe host, switch CommCell operations back to the production CommServe host by resetting the maintenance failover.

## Procedure

1. Log on to either the production CommServe host, or the standby CommServe host.

2. Open command prompt and navigate to the folder associated with the SQL client:

   For example: opt/commvault2/Base

3. Execute the following command to reset a maintenance failover, to the SQL client in the production CommServe host:

       ./CvFailover -OpType Failover -FailoverType MaintenanceFailback -TargetNode ActiveSQLClient

   Syntax:

       ./CvFailover -OpType $[OpType] -FailoverType $[Failover Type] -TargetNode $[Target Node Name]

   Where:

   - `<OpType>` can be one of the following operations:

     Failover - To perform a failover operation.

     GetFailoverConfig - To display the failover configuration status.

     ResetFailoverOperation - To reset a partial failover operation.

     ResetFailoverConfig - To reset an existing failover configuration. (To be used in case of xml corruption.)

   - `<Failover Type>` can be one of the following failover types:

     Production - To perform a production failover.

     ProductionMaintenance - To perform a maintenance failover.

     MaintenanceFailback option - To reset maintenance failover.

     Test - To perform a test failover.

     TestFailback - To reset a test failover.

   - `<Target Node Name>` is the name of the target SQL client in the CommServe host to which the operation must be failed over.

   - -forceUnplannedFailover can be used when the setup is stuck and only when the target node is the node with latest database, to avoid major data loss.

## Result

- The sequence of tasks performed to complete the reset is displayed. The CommServe is redirected back to the production CommServe host.

- All activities in the CommCell are enabled, and all jobs are automatically resumed in the Job Controller.

## What to Do Next

If client certificate authentication during installation was disabled before the failover, set the Force per-client certificate authentication option to Yes from the CommCell Console > Control Panel > Certificate Administration dialog box.
