Description

The Set-SRGroup cmdlet modifies settings of an existing replication group. A replication group contains one or more data volumes and an associated log volume. A replication group is the container for replication.

Examples

Example 1: Add a volume to a replication group

Set-SRGroup -Name "ReplicationGroup01" -AddVolumeName "F:"

This command adds the F: volume to the existing replication group named ReplicationGroup01 on the local computer.

Example 2: Remove a volume from a replication group

Set-SRGroup -Name "ReplicationGroup01" -RemoveVolumeName "F:"

This command removes the F: volume from the existing replication group ReplicationGroup01 on the local computer.

Example 3: Resize volumes in a replication group

Set-SRGroup -Name "ReplicationGroup01" -AllowVolumeResize $True

This command lets you resize volumes in the replication group named ReplicationGroup01 on the local computer. By default, the Storage Replica driver prevents volume resizes in order to protect from block mismatches. To grow a volume, enable the allow volume resize mode on both resource groups, increase the size of the volume on both servers to be the same size, then disable this mode.

Parameters

-AddVolumeName

Specifies an array of drive letters or mount point paths of partitions for the replica to add to the group. The volumes must exist. The volumes cannot be mapped drives or UNC paths.

This is an ordered list. The order of volumes determines the order of replication. For more information, see the DestinationVolumeName parameter of the New-SRPartnership cmdlet.

Type:	String[]
Aliases:	AV
Position:	2
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-AllowVolumeResize

Indicates that the replication group enables resizing of volumes.

Type:	Boolean
Aliases:	VR
Position:	10
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-AsJob

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

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-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.

Type:	CimSession[]
Aliases:	Session
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Compression

Indicates that this Storage Replica group should use SMB compression for data transfer.

Type:	Boolean
Aliases:	CMP
Position:	10
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-ComputerName

Specifies a single replica host computer NetBIOS name or fully qualified domain name (FQDN) of a computer. The default value is the local computer.

Type:	String
Aliases:	CN
Position:	0
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Description

Specifies a description for the replication group.

Type:	String
Aliases:	D
Position:	6
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Encryption

Indicates this partnership should encrypt connections by using SMB AES-128-GCM. Enabling encryption can protect Storage Replica block transfers from man-in-the-middle interception or reading. Enabling encryption decreases performance.

Type:	Boolean
Aliases:	ENC
Position:	9
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Force

Forces the command to run without asking for user confirmation.

Type:	SwitchParameter
Aliases:	F
Position:	100
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-LogSizeInBytes

Specifies the aggregate size of log files on each server in the replication group for the volumes that are associated with this replication group. The minimum size 512MB. You can specify a value by using the Windows PowerShell byte conversion capability, such as 4GB or 3200MB.

A value that is too small may cause decreased replication performance or increased recovery time after an interruption between computers.

Type:	UInt64
Aliases:	LS
Position:	4
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Name

Specifies the name of the replication group to modify.

Type:	String
Aliases:	N
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-RemoveVolumeName

Specifies an array of drive letters or mount point paths of partitions for the replica to remove from the group. The volumes must exist. The volumes cannot be mapped drives or UNC paths.

This is an ordered list. The order of volumes determines the order of replication. For more information, see the DestinationVolumeName parameter of the New-SRPartnership cmdlet.

If there is a partnership already configured, before you change this replication group, you must remove the partnership by using the Set-SRPartnership cmdlet. Then you must remove the same volumes from the previously partnered replication group.

Type:	String[]
Aliases:	RVN
Position:	3
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-ReplicationMode

Specifies the desired mode of replication for this source and destination pair. The acceptable values for this parameter are:

• Synchronous or 1. The synchronous mode requires all writes to commit on the destination server and commit on the source server, which guarantees data integrity between computers.
• Asynchronous or 2. The asynchronous mode writes to the source server without waiting for the source server, which allows for replication over high latency, geographic networks.

The default value is synchronous. The default asynchronous recovery point alert time is 5 minutes. You can modify it by using the Set-SRPartnership cmdlet. The alert time has no effect on replication behavior, only on reporting.

Type:	ReplicationMode
Aliases:	RM
Accepted values:	Synchronous, Asynchronous
Position:	8
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-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.

Type:	Int32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-WhatIf

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

Type:	SwitchParameter
Aliases:	wi
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
