Module availability, target configuration and delegated permissions determine whether it can run in your environment. Documentation and parameter text: Microsoft, CC BY 4.0; formatting adapted by Cmdlet World. No execution testing is claimed.

 [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]

Required permissions

Use an account with the target resource permissions documented for Grant-SRAccess. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Supported environments

Windows / StorageReplica · Windows Server 2025 documentation; feature/module prerequisites apply

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

-Cluster (required)

Specifies a partner failover cluster NetBIOS name or fully qualified domain name (FQDN) of a cluster. This cmdlet adds this cluster to the Storage Replica access control list on the local cluster to enable replication. You must run this cmdlet for both clusters before you create a partnership.

-ComputerName

Specifies a single replica host computer NetBIOS name or FQDN on which this cmdlet grants access. The default value is the local computer.

-Confirm

Prompts you for confirmation before running the cmdlet.

-Force

Forces the command to run without asking for user confirmation.

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Prerequisites

Windows with the StorageReplica module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.

Security considerations

This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.

Examples
