Function Get-DbaAvailabilityGroup { <# .SYNOPSIS Outputs information of the Availabilty Group(s) found on the server. .DESCRIPTION By default outputs a small set of information around the Availability Group found on the server. .PARAMETER SqlServer The SQL Server instance. You must have sysadmin access and server version must be SQL Server version 2012 or higher. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. .PARAMETER Detailed Output is expanded with more information around each Availability Group replica found on the server. .PARAMETER AvailabilityGroups Specify the Availability Group name that you want to get information on. .PARAMETER Simple Show only server name, availability groups and role. .PARAMETER Detailed Shows detailed information about the AGs including EndpointUrl and BackupPriority. .PARAMETER IsPrimary Returns true or false for the server passed in. .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. .NOTES Tags: DisasterRecovery, Backup Original Author: Shawn Melton (@wsmelton) | Chrissy LeMaire (@ctrlb) dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
