Enables failover on an exchange database availability group (DAG) that has been provisioned using ESI.
Syntax
Enable-EmcExchangeFailover [-DatabaseAvailabilityGroup] <DatabaseAvailabilityGroup> [-Silent] [<CommonParameters>]
Description
This command can be used together with the Disable-EmcExchangeFailover and Update-EmcHAExtension cmdlets to prepare a database for failover operations. The Enable-EmcExchangeFailover example shows how to do this.
Parameters
-DatabaseAvailabilityGroup <DatabaseAvailabilityGroup>
Attributes: Required, Position: 2
Specifies the DAG to enable failover on.
-Silent <SwitchParameter>
Attributes: Optional, Position: named
Turns off all the informational and verbose messages. However, it still displays errors.
<CommonParameters>
This cmdlet supports these common parameters: Verbose, Debug, ErrorAction, ErrorVariable, WarningAction, WarningVariable, OutBuffer, and OutVariable. Type get-help about_commonparameters for more details.
-------------- Example 1 --------------
C:\PS>$dag = Get-EmcDatabaseAvailabilityGroup MyDAG
C:\PS>Disable-EmcExchangeFailover $dag
# Before invoking the next command the Administrator should create databases and database copies in the DAG
C:\PS>Update-EmcHAExtension $dag
C:\PS>Enable-EmcExchangeFailover $dag
This example disables failover on the MyDAG DAG, updates the database copy map, and then re-enables failover.
