New-DatabaseAvailabilityGroupNetwork

Applies to: Exchange Server 2010

Topic Last Modified: 2011-03-19

Use the New-DatabaseAvailabilityGroupNetwork cmdlet to manually create a network for a database availability group (DAG). After you create DAG networks, you can use them for log shipping and seeding for mailbox databases hosted on servers in the DAG, or use them for client access to mailbox databases in the DAG.

Support for network encryption and network compression in a DAG is configured at the DAG level, and not at the network level. You can use the Set-DatabaseAvailabilityGroup cmdlet to configure network encryption and compression settings for the DAG.


New-DatabaseAvailabilityGroupNetwork -Name <String> -DatabaseAvailabilityGroup <DatabaseAvailabilityGroupIdParameter> [-Confirm [<SwitchParameter>]] [-Description <String>] [-DomainController <Fqdn>] [-IgnoreNetwork <$true | $false>] [-ReplicationEnabled <$true | $false>] [-Subnets <DatabaseAvailabilityGroupSubnetId[]>] [-WhatIf [<SwitchParameter>]]

Parameter Required Type Description

DatabaseAvailabilityGroup

Required

Microsoft.Exchange.Configuration.Tasks.DatabaseAvailabilityGroupIdParameter

The DatabaseAvailabilityGroup parameter specifies the name of the DAG that'll use the network being created.

Name

Required

System.String

The Name parameter specifies the name of the network being created.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch 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 switch.

Description

Optional

System.String

The Description parameter specifies an optional description of up to 256 characters for the network being created.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.

IgnoreNetwork

Optional

System.Boolean

The IgnoreNetwork parameter excludes a network from use by the DAG.

ReplicationEnabled

Optional

System.Boolean

The ReplicationEnabled parameter specifies whether the network being created is used for log shipping. Networks enabled for replication do not allow client access to databases in the DAG.

Subnets

Optional

Microsoft.Exchange.Data.DatabaseAvailabilityGroupSubnetId[]

The Subnets parameter is used to manually specify the subnets that make up the network being created.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, 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 switch.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the"database availability group" entry in the High Availability Permissions topic.

Error Description

 

This example creates a new DAG network named DAGNetwork1 for a DAG named DAG1. A subnet of 10.0.0.0 with a bitmask of 8 is assigned to the DAG network, and the DAG network is also enabled for replication activity.

New-DatabaseAvailabilityGroupNetwork -DatabaseAvailabilityGroup DAG1 -Name DAGNetwork1 -Subnets 10.0.0.0/8 -ReplicationEnabled:$true
