Prepare Database Server JBSAG1, JBSAG2 and JBSAG3
-> Make sure below ports are opened for JBSAG1, JBSAG2 and JBSAG3.
5022 (Always On Endpoint)
1433 (SQL Server PortListener Port)
58888 (Backend Pool Port)
Configure Cluster
-> Login to Database Server JBSAG1, JBSAG2 and JBSAG3 and execute below Powershell command. Refer this article for more details on Powershell command related to cluster configuration,
Install-WindowsFeature -Name "Failover-Clustering" -IncludeManagementTools
-> Once installed on both JBSAG1, JBSAG2 and JBSAG3. Restart the database servers.
-> Execute below powershell command that runs all cluster validation tests on Database Server JBASAG1, JBSAG2 and JBSAG3.
Test-Cluster –Node JBSAG1,JBSAG2,JBSAG3
-> View the report and make sure all looks fine.
-> Below hostname and IP Address will be utilized for Cluster and Always On Listener Configuration,
East US
West US
-> Execute below Powershell code to create a cluster,
New-Cluster -Name JBSWikiClust -Node JBSAG1,JBSAG2,JBSAG3 -StaticAddress 172.20.1.19,192.168.1.19 -NoStorage
Configure Always On Availability Group
-> Make sure SQL services are started with a proper Service account. In my case I have used account jbswiki\jbswiki as the SQL Service account.
-> Make sure [NT AUTHORITYSYSTEM] has appropriate access to SQL Server Instances.
-> Enable Always On feature for JBSAG1, JBSAG2 and JBSAG3 from Configuration Manager and restart SQL Server,
-> Configure Always On,
Configure Always On Availability Group Listener
-> Below hostname and IP Address will be utilized for Cluster and Always On Listener Configuration,
East US
West US
-> Open Cluster Administrator, Start -> Run -> cluadmin.msc on Primary Replica JBSAG1,
-> Right click “IP Address 192.168.1.0” and click Properties,
-> Once created, Stop the Role as below,
-> Right click AG resource and click properties,
-> Click dependencies and add the IP Address resource as a dependency,
-> Execute below powershell command on JBSAG1, JBSAG2 and JBSAG3 to set the cluster parameters,
Import-Module FailoverClusters
# Availability Group Name
$AGName = "JBSAG"
$ClusterNetworkName = (Get-ClusterNetwork).Name
$IPResourceName = (Get-ClusterResource | Where-Object { $_.ResourceType -eq "IP Address" -and $_.OwnerGroup -eq $AGName}).Name
$ListenerILBIP = (Get-ClusterResource $IPResourceName | Get-ClusterParameter | Where-Object {$_.Name -eq "Address"}).Value
#Load Balancer Listener endpoint port
$ListenerProbePort = 58888
Get-ClusterResource $IPResourceName | Set-ClusterParameter -Multiple @{"Address"="$ListenerILBIP";"ProbePort"=$ListenerProbePort;"SubnetMask"="255.255.255.255";"Network"="$ClusterNetworkName";"EnableDhcp"=0}
Get-ClusterResource $IPResourceName-> Start the AG role,
-> Connect to the Primary replica using SQL Server Management Studio. Open the properties of Listener JBSAPP and enter the port number as appropriate,
-> Failover and failback Availability group from SQL Server Management Studio and check if Listener connection can be made.
