function Repair-DbaDbMirror {
    <#
    .SYNOPSIS
        Attempts to repair a suspended or paused mirroring database.
 
    .DESCRIPTION
        Attempts to repair a suspended mirroring database.
 
        Restarts the endpoints then sets the partner to resume. See this article for more info:
 
        http://www.sqlservercentral.com/blogs/vivekssqlnotes/2016/09/03/how-to-resume-suspended-database-mirroring-in-sql-server-/
 
    .PARAMETER SqlInstance
        The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function
        to be executed against multiple SQL Server instances.
 
    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
    .PARAMETER Database
        The target database.
 
    .PARAMETER InputObject
        Allows piping from Get-DbaDatabase.
 
    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.
 
    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.
 
    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
