说明

The New-SqlAvailabilityReplica cmdlet creates an availability replica. Run this cmdlet on the instance of SQL Server that hosts the primary replica.

To create an availability replica before you create an availability group, specify the AsTemplate parameter. To add a replica to an existing availability group, either the InputObject or Path parameter specifies the availability group.

示例

Example 1: Creates a representation of an availability replica

PS C:\> $ServerObject = Get-Item "SQLSERVER:\Sql\PrimaryServer\InstanceName"
PS C:\> New-SqlAvailabilityReplica -Name "PrimaryServer\Instance" -EndpointUrl "TCP://PrimaryServerName.domain.com:5022" -FailoverMode Automatic -AvailabilityMode SynchronousCommit -AsTemplate -Version $ServerObject.Version

This example creates an in-memory representation of an availability replica. No changes are committed to the server. You can use this replica as a value for the AvailabilityReplica parameter of New-SqlAvailabilityGroup

The first command gets an instance of the primary server.

The second command creates the availability replica. This replica uses the database mirroring endpoint located at the specified URL to communicate with other replicas in the availability group. This replica supports automatic failover and the synchronous-commit availability mode. The Version parameter specifies the version of the server instance that will host this new replica.

Example 2: Creates an availability replica that supports manual failover and the asynchronous-commit

PS C:\> $ServerObject = Get-Item "SQLSERVER:\Sql\PrimaryServer\InstanceName"
PS C:\> New-SqlAvailabilityReplica -Name "SecondaryServer\Instance" -EndpointUrl "TCP://PrimaryServerName.domain.com:5022" -FailoverMode Manual -AvailabilityMode AsynchronousCommit -AsTemplate -Version $ServerObject.Version

This example creates an in-memory representation of an availability replica. No changes are committed to the server.

The first command gets an instance of the primary server.

The second command creates the availability replica. This replica uses the database mirroring endpoint located at the specified URL to communicate with other replicas in the availability group. This replica supports manual failover and the asynchronous-commit availability mode. The Version parameter specifies the version of the server instance that will host this new replica.

Example 3: Add an availability replica to an availability group

PS C:\> New-SqlAvailabilityReplica -Name "SecondaryServer\Instance" -EndpointUrl "TCP://PrimaryServerName.domain.com:5022" -FailoverMode Manual -AvailabilityMode AsynchronousCommit -ConnectionModeInSecondaryRole AllowAllConnections -Path "SQLSERVER:\Sql\PrimaryServer\InstanceName\AvailabilityGroups\MainAG"

This command adds an availability replica to an existing availability group named MainAG. This replica supports manual failover and asynchronous-commit availability mode. In the secondary role, this replica supports read access connections. This configuration lets you offload read-only processing to this replica.

参数

-AsTemplate

Indicates that this cmdlet creates a temporary AvailabilityReplica object in memory. Specify this parameter to create an availability group before you create an availability replica. Create an availability group by using the New-SqlAvailabilityGroup cmdlet. Specify the temporary availability replica as the value of the AvailabilityReplica parameter.

If you specify AsTemplate, this cmdlet ignores values for the InputObject and Path parameters.

If you specify this parameter, you must also specify a SQL Server version for the Version parameter, or your current session must have an active connection to an instance.
