Parameters

-CheckpointKey: Specifies a comma-separated list of registry checkpoint keys to add for this highly available generic application. All registry paths are relative to HKEY_LOCAL_MACHINE.
-Cluster: Specifies the name of the cluster on which to run this cmdlet. If the input for this parameter is . or it is omitted, then the cmdlet runs on the local cluster.
-CommandLine (required): Specifies the Windows PowerShell command line to use for the highly available generic application. If the full path is specified, then the current directory is parsed out of the Windows PowerShell command line.
-IgnoreNetwork: Specifies one or more networks to ignore when running the cmdlet. Networks with DHCP enabled are always included, but other networks need a static address to be specified using the StaticAddress parameter or should be explicitly ignored with this IgnoreNetwork parameter.
-InputObject: Specifies the cluster on which to create the highly available application.
-Name: Specifies the name of the highly available application to create.
-Parameters: Specifies the parameters to use for the highly available generic application.
-StaticAddress: Specifies one or more static addresses to use when running the cmdlet. Networks with DHCP enabled are always included, but other networks need a static address to be specified using the StaticAddress parameter or should be explicitly ignored with this IgnoreNetwork parameter.
-Storage: Specifies the cluster disk resource to be added to the created highly available application.
-Wait: Specifies the time in seconds to wait for the cmdlet. If the Wait parameter isn't specified, then the cmdlet waits for completion. If the value 0 is specified, then the call is initiated and the cmdlet returns without waiting.

Prerequisites

Windows with the FailoverClusters 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.
