Use the Dismount-Database cmdlet to dismount a database in a storage group on an Microsoft Exchange Server 2007 mailbox server. You can run this command only if the Microsoft Exchange Information Store service is running.


dismount-Database -Identity <DatabaseIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

To run the Dismount-Database cmdlet, the account you use must be delegated the following:

  • Exchange Server Administrator role and local Administrators group for the target server

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.

 

Parameter Required Type Description

Identity

Required

Microsoft.Exchange.Configuration.Tasks.DatabaseIdParameter

Use the Identity parameter to specify the GUID or distinguished name that represents a specific database. You can also include the server name by using the format ServerName\StorageGroup. The "Identity" parameter label is optional.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm parameter causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm parameter.

DomainController

Optional

To specify the fully qualified domain name of the domain controller that writes this configuration change to Active Directory, include the DomainController parameter on the command.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf parameter instructs the command to simulate the actions that it would take on the object. By using the WhatIf parameter, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf parameter.
