Description

The Suspend-SqlAvailabilityDatabase cmdlet suspends data movement on an availability database. This cmdlet suspends a database on the replica that is hosted by the current server instance. If you suspend a secondary database, this cmdlet sets its state to SUSPENDED. It falls behind the corresponding primary database. If you suspend a primary database, data movement stops on every secondary replica.

Examples

Example 1: Suspend synchronization for a database

PS C:\> Suspend-SqlAvailabilityDatabase -Path "SQLSERVER:\Sql\Server\Instance\AvailabilityGroups\MainAG\AvailabilityDatabases\Database16"

This command suspends data synchronization for the availability database Database16 in the availability group named MainAG on the server instance named Server\Instance.

Example 2: Suspend synchronization for all databases

PS C:\> Get-ChildItem "SQLSERVER:\Sql\Server\Instance\AvailabilityGroups\MainAG\AvailabilityDatabases" | Suspend-SqlAvailabilityDatabase

This command gets all the availability databases that belong to MainAG, and then passes them to the current cmdlet by using the pipeline operator. The current cmdlet suspends each availability database.

Example 3: Create a script to suspend a database

PS C:\> Suspend-SqlAvailabilityDatabase -Path "SQLSERVER:\Sql\Server\Instance\AvailabilityGroups\MainAG\AvailabilityDatabases\Database16" -Script

This command creates a Transact-SQL script that suspends the availability database named Database16 in the availability group named MainAG. The command does not perform this action.

Parameters

-AccessToken

The access token used to authenticate to SQL Server, as an alternative to user/password or Windows Authentication.

This can be used, for example, to connect to SQL Azure DB and SQL Azure Managed Instance using a Service Principal or a Managed Identity.

The parameter to use can be either a string representing the token or a PSAccessToken object as returned by running Get-AzAccessToken -ResourceUrl https://database.windows.net.

This parameter is new in v22 of the module.

Type:PSObject
Position:Named
Default value:None
Required:False
Accept pipeline input:False
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

-Encrypt

The encryption type to use when connecting to SQL Server.

This value maps to the Encrypt property SqlConnectionEncryptOption on the SqlConnection object of the Microsoft.Data.SqlClient driver.

In v22 of the module, the default is Optional (for compatibility with v21). In v23+ of the module, the default value will be 'Mandatory', which may create a breaking change for existing scripts.

This parameter is new in v22 of the module.

Type:String
Accepted values:Mandatory, Optional, Strict
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-HostNameInCertificate

The host name to be used in validating the SQL Server TLS/SSL certificate. You must pass this parameter if your SQL Server instance is enabled for Force Encryption and you want to connect to an instance using hostname/shortname. If this parameter is omitted then passing the Fully Qualified Domain Name (FQDN) to -ServerInstance is necessary to connect to a SQL Server instance enabled for Force Encryption.

This parameter is new in v22 of the module.

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

-InputObject

Specifies availability database, as an AvailabilityDatabase object, that this cmdlet suspends.

Type:AvailabilityDatabase[]
Position:1
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Path

Specifies the path of an availability database that cmdlet suspends. If you do not specify this parameter, this cmdlet uses current working location.

Type:String[]
Position:1
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ProgressAction

Determines how PowerShell responds to progress updates generated by a script, cmdlet, or provider, such as the progress bars generated by the Write-Progress cmdlet. The Write-Progress cmdlet creates progress bars that show a command's status.

Type:ActionPreference
Aliases:proga
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Script

Indicates that this cmdlet returns a Transact-SQL script that performs the task that this cmdlet performs.

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

-TrustServerCertificate

Indicates whether the channel will be encrypted while bypassing walking the certificate chain to validate trust.

In v22 of the module, the default is $true (for compatibility with v21). In v23+ of the module, the default value will be '$false', which may create a breaking change for existing scripts.

This parameter is new in v22 of the module.

Type:SwitchParameter
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

Inputs

Microsoft.SqlServer.Management.Smo.AvailabilityDatabase[]

You can pass an availability database to this cmdlet.
