How to Perform Forced Manual Failover of Availability Group (SQL Server) and WSFC (Windows Server Failover Cluster) with scrpiting

I have a scenario with the three nodes with server 2012 standard, each running an instance of SQL Server 2012 enterprise, participate in a
single Windows Server Failover Cluster (WSFC) that spans two data centers.
If the nodes in the primary data center are unavailable due to data center outage. Then how I can able to access node in the WSFC (Windows Server Failover Cluster) in the secondary disaster recovery data center automatically with some script.
I want to write script that can be able to check primary data center by pinging some IP after every 5 or 10 minutes.
If that IP is unable to respond then script can be able to Perform Forced Manual Failover of Availability Group (SQL Server) and WSFC (Windows Server Failover Cluster)
Can you please guide me for script writing for automatic failover in case of primary datacenter outage?

You are trying to implement manually what should be happening automatically in the cluster. If the primary SQL Server becomes unavailable in the data center, it should fail over to the secondary SQL Server automatically. Is that not working?
You also might want to run this configuration by some SQL experts. I am not a SQL expert, but if you have both hosts in the data center in a cluster, there is no need for replication between those two nodes as they would be accessing
the database from some form of shared storage. Then it looks like you are trying to implement Always On to the DR site. I'm not sure you can mix both types of failover in a single configuration.
FYI, it would make more sense to establish a file share witness in your DR site instead of placing a third node in the data center for Node Majority quorum.

please post you question on failover clusters in the cluster forum. THey will explain how this works and point you at scipts.
You should also look in the Gallery for cluster management scripts.

+1 to David's comment. I would not suggest to run a script automatically. During such failover you might have data loss and decision has to be made with business owners during disaster.
During such situation, you need to start cluster service in force quorum mode (/fq switch) and then perform manual failover of AG to DR site.

SQL AlwaysOn Availability Group modifies preferred owner node on move/failover

I have a two node Windows Server 2012 R2 failover cluster with two SQL Server 2012 Enterprise AlwaysOn Availability groups configured. Within the cluster I have configured a preference order on which node a AlwaysOn Availability Group should run.
Get-ClusterGroup -Name "AlwaysOn1" | Set-ClusterOwnerNode -Owners "node1","node2";
Get-ClusterGroup -Name "AlwaysOn2" | Set-ClusterOwnerNode -Owners "node2","node1";
After configuring the preference and retrieving the preference order it is configured as it should be. When I do a failover the preference order is adjusted to first the node it currently runs on and second the other node instead of leaving the preference
order as it was. It doesn't matter if I use the PowerShell "Move-ClusterGroup" or the "ALTER AVAILABILITY GROUP [AlwaysOn1] FAILOVER" T-SQL command. From the cluster log it is shown that the preference is modified after the resource
has been moved.
INFO [GUM] Node 2: executing request locally, gumId:15859, my action: /rcm/gum/SetGroupPreferredOwners, # of updates: 1
INFO [RCM] rcm::RcmGum::SetGroupPreferredOwners(AlwaysOn1,<vector len='2'>
The default groups within the cluster "Available Storage" and "Cluster Group" keep their preference setting when configured (only configured for testing to verify it has to do with the SQL Server Availability Group resource type).
The Windows Server 2012 R2 servers are updated using the latest Windows Updates and SQL 2012 has build number 11.0.5556.
For other cluster groups which I have configured in the past like file, Hyper-V (used for affinity to get VM's which have a lot of traffic between them within the same virtual switch to reduce latency and additional hops. it would be nice if vNext will have
a affinity option for cluster groups besides the anti-affinity within the current version)
I would like to know if someone could explain why the SQL Server Availability Group resource always modifies the group preference. I might understand this with a three node cluster where the first two are running in Synchronous commit mode and the third
one in Asynchronous commit mode.
Thanks in advance,
Dennis van den Akker

Hi Dennis van den Akker,
Do not use the Failover Cluster Manager to manipulate availability groups, for example:
Do not add or remove resources in the clustered service (resource group) for the availability group.
Do not change any availability group properties, such as the possible owners and preferred owners. These properties are set automatically by the availability group.
Do not use the Failover Cluster Manager to move availability groups to different nodes or to fail over availability groups. The Failover Cluster Manager is not aware of the synchronization status of the availability replicas, and doing so can lead to extended
downtime. You must use Transact-SQL or SQL Server Management Studio.

The lease timeout between avaiability group and the Windows Server Failover Cluster has expired

Hi,
I am having some issues where I get a lease timeout from time to time. I have a Windows 2012 Failover Cluster with 2 nodes and 2 SQL 2012 Always-on Availability Groups. Both nodes
are a physical machines and each node is the primary for an AG.
From what I understand if
the HealhCheckTimeout
is exceeded without the signal exchange the lease is declared 'expired' and the SQL Server resource dll reports that the SQL Server availability group no longer 'looks alive' to the Windows cluster manager. Here are the properties I have setup
which are the default settings:
LeaseTimeout - 20000
HealthCheckTimeout - 30000
VerboseLoging - 0>
FailureConditionLevel – 3
Here are the events that occur in the Application Event Viewer:
Event ID 19407:
The lease between availability group 'AG_NAME' and the Windows Server Failover Cluster has expired. A connectivity issue occurred between the instance of SQL Server and the Windows Server Failover
Cluster. To determine whether the availability group is failing over correctly, check the corresponding availability group resource in the Windows Server Failover Cluster.
Event ID 35285:
The recovery LSN (120881:37533:1) was identified for the database with ID 32. This is an informational message only. No user action is required.
SQl server logs are too long to post in this box but I can send them if you request.
The AG is setup to failover automatically but it did not failover. I am trying to figure out why the lease timed out. Thanks.

From what I've been able to find out, this is due to an issue with the procedure sp_server_diagnostics. It sounds like the cluster is expecting this procedure to regularly log good status "Clean" in the log files, but the procedure is designed not
to flood the logs with "Clean" messages, so only reports changes, and does not make an entry when the last status was "Clean" and the current status is "Clean". The result is that the cluster looks to be unresponsive. However, once it initiates
the failover, the primary machine responds, since it was never really down, and the failover operation stops.
The end result is that there really never is a failover, but the database becomes unavailable for a few minutes while this is resolved.
I'm going to try setting the cluster's failure condition level to 2 (instead of 3) and see if that prevents the down time.

[Forum FAQ] How to install and configure Windows Server Essentials Experience role on Windows Server 2012 R2 Standard via PowerShell locally and remotely

As we all know,
the Windows Server Essentials Experience role is available in Windows Server 2012 R2 Standard and Windows Server 2012 R2 Datacenter. We can add the Windows Server
Essentials Experience role in Server Manager or via Windows PowerShell.
In this article, we introduce the steps to install and configure Windows
Server Essentials Experience role on Windows Server 2012 R2 Standard via PowerShell locally and remotely. For better analyze, we divide this article into two parts.
Before installing the Windows Server Essentials Experience Role, please use
Get-WindowsFeature
PowerShell cmdlet to ensure the Windows Server Essentials Experience (ServerEssentialsRole) is available. (Figure 1)
Figure 1.
Part 1: Install Windows Server Essentials Experience role locally
Add Windows Server Essentials Experience role
Run Windows PowerShell as administrator, then type
Add-WindowsFeature ServerEssentialsRole cmdlet to install Windows Server Essentials Experience role. (Figure 2)
Figure 2.
Note: It is necessary to configure Windows Server Essentials Experience (Post-deployment Configuration). Otherwise, you will encounter following issue when opening Dashboard.
(Figure 3)
Figure 3.
2. Configure Windows Server Essentials Experience role
(1) In an existing domain environment
Firstly, please join the Windows Server 2012 R2 Standard computer to the existing domain through the path:
Control Panel\System\Change Settings\”Change…”\Member of. (Figure 4)
Figure 4.
After that, please install Windows Server Essentials Experience role as original description. After installation completed, please use the following command to configure Windows
Server Essentials:
Start-WssConfigurationService –Credential <Your Credential>
Note: The type of
Your Credential should be as: Domain-Name\Domain-User-Account.
You must be a member of the Enterprise Admin group and Domain Admin group in Active Directory when using the command above to configure Windows Server Essentials. (Figure 5)
Figure 5.
Next, you can type the password for the domain account. (Figure 6)
Figure 6.
After setting the credential, please type “Y” to continue to configure Windows Server Essentials. (Figure 7)
Figure 7.
By the way, you can use
Get-WssConfigurationStatus
PowerShell cmdlet to
get the status of the configuration of Windows Server Essentials. Specify the
ShowProgress parameter to view a progress indicator. (Figure 8)
Figure 8.
(2) In a non-domain environment
Open PowerShell (Run as Administrator) on the Windows Server 2012 R2 Standard and type following PowerShell cmdlets: (Figure 9)
Start-WssConfigurationService -CompanyName "xxx" -DNSName "xxx" -NetBiosName "xxx" -ComputerName "xxx” –NewAdminCredential $cred
Figure 9.
After you type the commands above and click Enter, you can create a new administrator credential. (Figure 10)
After creating the new administrator credential, please type “Y” to continue to configure Windows Server Essentials. (Figure 11)
After a reboot, all the configurations will be completed and you can open the Windows Server Essentials Dashboard without any errors. (Figure 12)
Figure 12.
Please click to vote if the post helps you. This can be beneficial to other community members reading the thread.

Part 2: Install and configure Windows Server Essentials Experience role remotely
In an existing domain environment
In an existing domain environment, please use following command to provide credential and then add Server Essentials Role: (Figure 13)
Add-WindowsFeature -Name ServerEssentialsRole
-ComputerName xxx -Credential DomainName\DomainAccount
Figure 13.
After you enter the credential, it will start install Windows Server Essentials role on your computer. (Figure 14)
Figure 14.
After the installation completes, it will return the result as below:
Figure 15.
Next, please use the
Enter-PSSession
cmdlet and provide the correct credential to start an interactive session with a remote computer. You can use the commands below:
Enter-PSSession –ComputerName
xxx –Credential DomainName\DomainAccount (Figure 16)
Figure 16.
Then, please configure Server Essentials Role via
Add-WssConfigurationService cmdlet and it also needs to provide correct credential. (Figure 17)
Figure 17.
After your credential is accepted, it will update and prepare your server. (Figure 18)
Figure 18.
After that, please type “Y” to continue to configure Windows Server Essentials. (Figure 19)
Figure 19.
2. In a non-domain environment
In my test environment, I set up two computers running Windows Server 2012 R2 Standard and use Server1 as a target computer. The IP addresses for the two computers are as
below:
Sevrer1: 192.168.1.54
Server2: 192.168.1.53
Run
Enable-PSRemoting –Force on Server1. (Figure 20)
Figure 20.
Since there is no existing domain, it is necessary to add the target computer (Server1) to a TrustedHosts list (maintained by WinRM) on Server 2. We can use following command
to
add the TrustedHosts entry:
Set-Item WSMan:\localhost\Client\TrustedHosts IP-Address
(Figure 21)
Figure 21.
Next, we can use
Enter-PSSession
cmdlet and provide the correct credential to start an interactive session with the remote computer. (Figure 22)
Figure 22.
After that, you can install Windows Server Essentials Experience Role remotely via Add-WindowsFeature ServerEssentialsRole cmdlet. (Figure 23)
Figure 23.
From figure 24, we can see that the installation is completed.
Figure 24.
Then you can use
Start-WssConfigurationService cmdlet to configure Essentials Role and follow the steps in the first part (configure Windows Server Essentials Experience in a non-domain environment) as the steps would be the same.
The figure below shows the status of Windows Server Essentials.
Figure
25.
Finally, we have successfully configured Windows Server Essentials on Server1. (Figure 26)
Figure 26.

How to monitor MySQL Server installed in Windows Server using Nagios

You can do this via NSClient as Gary posted. The NSClient is a communications system that allows nagios to send commands to a target system over the nsclient protocol and they are executed on the remote system. You will still have to build some kind of vbscript or plugin to run on the target system to do the actual query to check on mysql.There are other options to. If you enable snmp on your target computer you can use a few nagios plugins to query the snmp agent on the target computer to see if a service is running. To do this via snmp you will need this plugin "check_snmp_process.pl" fromthis site.Your check command will look something like this:check_win_process:= check_snmp_process.pl -H $HOSTADDRESS$ -C "$USER6$" -n "$ARG1$" -w $ARG2$ -c $ARG3$The service definition will be like this:check_win_process!sqlservr!0!0This will check...

I installed Nagios Core in my Ubuntu workstation 10.04 for me to learn something new in my craft. I use this now to monitor our Windows Server 2008 with MySQL server installed as well as our Datalink Switch (DGS-1210-24). I searched on google on how to monitor a MYSQL server installed in Windows server using Nagios Core but i could not seem to find any. Could anybody who's expert in Nagios give me steps on how to do so. Thanks. All i found in google were steps in monitoring mysql installed in linux and nothing in windows server.

Cluster failover but Availability Group do not

We recently had an issue where a file share was unavailable. It caused the cluster to failover. However, the Availability Group did not failover. The application was trying to connect to the secondary database which it couldn't since the failover had not
happened. We are set up using Quorum with a File Share Witness. We have manually failed this over successfully. Any ideas on why the Availability Group did not failover would be most appreciated. We do not have any experts in this area so please help us figure
out where to look.

Availability listener are a good way of providing a fault tolerance for the client and in addition providing read-intent or read-only access to the secondary replicas. If you need it, you can go through these documentations. They show the why and how to
set them up. If you have any additinal questions let me know.

Always make sure to configure AG relevenat parts through SSMS not the cluster Service manager itself. There are some points that you might want to tweak in the cluster manager, but most parts should be configured (and for most cases they are sufficient)
in the SQL Server related tools (SSMS)

How come the same apps that are available for my iPhone and my iPad are not the same as the apps in the app store on my mac

I want some of the same apps available on my iphone and ipad2 to be available on my macbook pro app store and to be able to link them through icloud. Is this not possible? If not, why not?

The Mac uses Mac OS X and iDevices use iOS. These are two different operating systems and the apps must be written for each operating system specifically, even when the apps go by the same name, such as the iWork apps, they are two ifferent versions of the same app for the two different platforms.
So, as an example, Safari has been written for three different operating systems, Mac OS X, iOS and Windows. And the Safari apps, as similar as they are visually, are not interchangeable for the different platforms.
