詳細描述

The Start-VMInitialReplication cmdlet starts replication of a virtual machine using the method you select. You also can schedule replication to start up to 7 days later.

參數

-AsJob

Runs the cmdlet as a background job.

-CimSession<Microsoft.Management.Infrastructure.CimSession[]>

在遠端工作階段或遠端電腦上執行 Cmdlet。輸入電腦名稱或工作階段物件，例如 New-CimSession 或 Get-CimSession Cmdlet 的輸出。預設為本機電腦上目前的工作階段。

-ComputerName<String[]>

Specifies one or more Hyper-V hosts on which replication of a virtual machine is to be started. NetBIOS names, IP addresses, and fully qualified domain names are allowable. The default is the local computer. Use localhost or a dot (.) to specify the local computer explicitly.

-Credential<System.Management.Automation.PSCredential[]>

Specifies one or more user accounts that have permission to perform this action. The default is the current user.

-DestinationPath<String>

Specifies the path to use when copying the files for initial replication; assumes use of external media as the method for initial replication. External media is typically a removable drive that is shipped to the location of the Replica server. When the external media arrives at the Replica site, use the Import-InitialVMReplication on the Replica virtual machine to copy the files.

-InitialReplicationStartTime<DateTime]>

Specifies the time to start the initial replication, when scheduling initial replication to occur later. You can specify a time up to 7 days later. When this parameter is not specified, initial replication occurs immediately.

-Passthru

Specifies that a virtual machine object is to be passed through to the pipeline representing the virtual machine on which replication is to be started.

-VM<VirtualMachine[]>

Specifies the virtual machine on which replication is to be started.

-VMName<String[]>

Specifies the name of the virtual machine on which replication is to be started.

-VMReplication<VMReplication[]>

Specifies an object that represents the replication to be started. You can get this object from the Get-VMReplication cmdlet.

-UseBackup

Indicates that you want to use a copy of this virtual machine on the Replica server as the basis for the initial replication. Specify this option only if it was specified when replication was enabled on the primary virtual machine.

-Confirm

在執行指令程式之前提示您確認。

-WhatIf

輸入

輸入類型是可透過管道傳送至指令程式的物件類型。

輸出

輸出類型是指令程式所發出的物件類型。

• None by default; Microsoft.HyperV.PowerShell.VirtualMachine if –PassThru is specified.

範例

Example 1

This example starts initial replication of virtual machine VM01 over the network.

PS C:\> Start-VMInitialReplication VM01

Example 2

This example starts initial replication over the network for all the virtual machines on the local Hyper-V host for which initial replication is pending.

PS C:\> Start-VMInitialReplication *

Example 3

This example exports the initial replication of all virtual machines on the local Hyper-V host for which initial replication is pending, to the location R:\IRLoc. This example assumes that the location is an external drive, which would be shipped to the Replica site so that the initial replication can be completed.

PS C:\> Start-VMInitialReplication * -DestinationPath R:\IRLoc

Example 4

This example uses several consecutive commands to start initial replication from backup. First, it enables a restored copy of virtual machine VM01 on the Replica server as a Replica virtual machine. Then, it enables replication for VM01 from the primary server. Finally, it starts the initial replication to use the restored copy of VM01 on Replica server as the basis of the initial replication.

PS C:\> Enable-VMReplication VM01 -AsReplica –computername MyReplica.contoso.com
PS C:\> Enable-VMReplication VMO1 -ReplicaServerName ReplicaServer01 -ReplicaServerPort 80 -AuthenticationType Kerberos –computername MyPrimary.contoso.comPS
PS C:\> Start-VMInitialReplication VM01 –usebackup –computername MyPrimary.contoso.com

Example 5

The first command returns a VMReplication object for the VM named MyVM and stores it in the variable $VMRepl.

The second cmdlet then uses this object to start the initial replication for the stored VM.

PS C:\> $VMRepl = Get-VMReplication -VMName MyVM 
PS C:\> Start-VMInitialReplication -VMReplication $VMRepl
