<h2 id="synopsis">Synopsis</h2>
<p>Automates the creation of availability groups.</p>
<h2 id="description">Description</h2>
<p>Automates the creation of availability groups.</p>
<ul>
<li>Checks prerequisites</li>
<li>Creates Availability Group and adds primary replica</li>
<li>Grants cluster permissions if necessary</li>
<li>Adds secondary replica if supplied</li>
<li>Adds databases if supplied
<ul>
<li>Performs backup/restore if seeding mode is manual</li>
<li>Database has to be in full recovery mode (so at least one backup has been taken) if seeding mode is automatic</li>
</ul>
</li>
<li>Adds listener to primary if supplied</li>
<li>Joins secondaries to availability group</li>
<li>Grants endpoint connect permissions to service accounts</li>
<li>Grants CreateAnyDatabase permissions if seeding mode is automatic</li>
<li>Returns Availability Group object from primary</li>
</ul>
<p>NOTES:</p>
<ul>
<li>If a backup / restore is performed, the backups will be left intact on the network share.</li>
<li>If you're using SQL Server on Linux and a fully qualified domain name is required, please use the FQDN to create a proper Endpoint</li>
</ul>
<p>PLEASE NOTE THE CHANGED DEFAULTS:<br />
Starting with version 1.1.x we changed the defaults of the following parameters to have the same defaults<br />
as the T-SQL command &quot;CREATE AVAILABILITY GROUP&quot; and the wizard in SQL Server Management Studio:</p>
<ul>
<li>ClusterType from External to Wsfc (Windows Server Failover Cluster).</li>
<li>FailureConditionLevel from OnServerDown (Level 1) to OnCriticalServerErrors (Level 3).</li>
<li>ConnectionModeInSecondaryRole from AllowAllConnections (ALL) to AllowNoConnections (NO).<br />
To change these defaults we have introduced configuration parameters for all of them, see documentation of the parameters for details.</li>
</ul>
