Synopsis

Calls the Amazon Relational Database Service FailoverGlobalCluster API operation.

Syntax

Start-RDSFailoverGlobalCluster

-AllowDataLoss <Boolean>
-Switchover <Boolean>
-TargetDbClusterIdentifier <String>
-Select <String>
-Force <SwitchParameter>
-ClientConfig <AmazonRDSConfig>

Description

Promotes the specified secondary DB cluster to be the primary DB cluster in the global database cluster to fail over or switch over a global database. Switchover operations were previously called "managed planned failovers." Although this operation can be used either to fail over or to switch over a global database cluster, its intended use is for global database failover. To switch over a global database cluster, we recommend that you use the SwitchoverGlobalCluster operation instead. How you use this operation depends on whether you are failing over or switching over your global database cluster:
  • Failing over - Specify the AllowDataLoss parameter and don't specify the Switchover parameter.
  • Switching over - Specify the Switchover parameter or omit it, but don't specify the AllowDataLoss parameter.
About failing over and switching over While failing over and switching over a global database cluster both change the primary DB cluster, you use these operations for different reasons:
  • Failing over - Use this operation to respond to an unplanned event, such as a Regional disaster in the primary Region. Failing over can result in a loss of write transaction data that wasn't replicated to the chosen secondary before the failover event occurred. However, the recovery process that promotes a DB instance on the chosen seconday DB cluster to be the primary writer DB instance guarantees that the data is in a transactionally consistent state. For more information about failing over an Amazon Aurora global database, see Performing managed failovers for Aurora global databases in the Amazon Aurora User Guide.
  • Switching over - Use this operation on a healthy global database cluster for planned events, such as Regional rotation or to fail back to the original primary DB cluster after a failover operation. With this operation, there is no data loss. For more information about switching over an Amazon Aurora global database, see Performing switchovers for Aurora global databases in the Amazon Aurora User Guide.

Parameters

-AllowDataLoss <Boolean>
Specifies whether to allow data loss for this global database cluster operation. Allowing data loss triggers a global failover operation.If you don't specify AllowDataLoss, the global database cluster operation defaults to a switchover.Constraints:
  • Can't be specified together with the Switchover parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ClientConfig <AmazonRDSConfig>
Amazon.PowerShell.Cmdlets.RDS.AmazonRDSClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-GlobalClusterIdentifier <String>
The identifier of the global database cluster (Aurora global database) this operation should apply to. The identifier is the unique key assigned by the user when the Aurora global database is created. In other words, it's the name of the Aurora global database.Constraints:
  • Must match the identifier of an existing global database cluster.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'GlobalCluster'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.RDS.Model.FailoverGlobalClusterResponse). Specifying the name of a property of type Amazon.RDS.Model.FailoverGlobalClusterResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Switchover <Boolean>
Specifies whether to switch over this global database cluster.Constraints:
  • Can't be specified together with the AllowDataLoss parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-TargetDbClusterIdentifier <String>
The identifier of the secondary Aurora DB cluster that you want to promote to the primary for the global database cluster. Use the Amazon Resource Name (ARN) for the identifier so that Aurora can locate the cluster in its Amazon Web Services Region.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesSK, SecretAccessKey
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesST

Outputs

Amazon.RDS.Model.GlobalCluster or Amazon.RDS.Model.FailoverGlobalClusterResponse
This cmdlet returns an Amazon.RDS.Model.GlobalCluster object. The service call response (type Amazon.RDS.Model.FailoverGlobalClusterResponse) can be returned by specifying '-Select *'.
