Step-by-Step: Configuring a 2-node multi-site cluster on Windows

Server 2008 R2 Part 3

SQL Server 2008 multi-site cluster on Windows

Server 2008 R2

In Part 1 of this series, I showed you how to prepare your multi-site cluster, including setting up the Node and File

Share Majority Quorum. In Part 2, we saw a video example of how to integrate SteelEye DataKeeper, one of the

available cluster replication solutions, with failover clustering to configure a multi-site Hyper-V failover cluster. In Part

3, we will examine how Microsoft SQL Server 2008 can be configured in a multi-site cluster with Windows Server

2008 Failover Clustering and SteelEye DataKeeperCluster Edition.

First, why would you want to deploy a multi-site SQL server cluster? SQL Server comes with a variety of high

availability options, including log shipping, replication (transactional, merge, snapshot), database mirroring and failover

clusters. There is a great article that talks about the High Availability options in SQL Server 2008, so I wont re-inventthe wheel here. If you want to learn more about all of the options, have a look at this article by Ross Mistry, High

Availability Options in SQL Server 2008.

If you read the article, Ross summary makes the following statement

Clearly, failover clustering is the best choice to reduce system downtime and provide higher application

availability for the whole instance of SQL Serverwithin a site; however, a failover cluster does notprotect against disk failure and requires a SAN.

What if you could have all ofthe benefits that Ross outlines and also protect against disk failure and eliminate the need

for a SAN? Well, the good news is that is exactly what you can do by implementing a Microsoft SQL Server 2008

multi-site cluster on Windows Server 2008. SQL Server 2008 multi-site cluster may be a little bit of a misnomer. It

2008 R2 is released. So, for the time being, you will have to span your subnet if you wish to separate your nodes

geographically.

Now that you have determined to deploy a multi-node SQL server cluster, here are the steps you will need to follow.

Configure you basic cluster

Follow the steps in Part 1 of this series to configure a basic 2-node cluster with a Node and File Share Majority

Quorum.

Configure your replicationDeploying a multi-site cluster will require that you work very closely with your replication vendor during this part of the

configuration. Each vendor will have very specific instructions on how to set up the replication and create the storage

resources to be used in your cluster. For the purposes of this demonstration, I will use SteelEye DataKeeper Cluster

Edition to replicate the E drive from the server named PRIMARY to the server named SECONDARY. The E drive

on PRIMARY and SECONDARY are just local attached volumes and not part of any SAN. As long as the E drive

shows up as a local attached disk, DataKeeper can replicate it from one server to another. You can mix and matchSAS, iSCSI, SAN, VHD, or any other storage type as DataKeeper is storage agnostic.

After you have configured your basic cluster as described in Part 1 of my series, run the DataKeeper setup.exe to

install SteelEye DataKeeper Cluster Edition on both nodes of the cluster. You will be prompted to enter your license

key at the end of the install. Enter your license and reboot your servers when prompted. You are now ready to create

your mirror. Launch the DataKeeper GUI and follow the instructions below to create your mirror.

Click on Connect to Server.

Once you have created your mirror, you need to make your mirror available in the Microsoft Cluster Available

Storage. There are a few ways to do this, but the most straight forward way is to use the Windows PowerShell CLI.

Below is an example that shows how to take the existing mirror we just created on the E drive and add it to the cluster

Available Storage, move it to the PRIMARY node and bring it in-service

SQL 2008 is very dependent upon MSDTC, so it is highly recommended that you cluster the MSDTC resource

before you cluster your SQL resource. The following articles are provided for your reference for configuration and

management of your MSDTC resource.

We are just about ready to begin the installation of the first node of the SQL Server Cluster, however, there is one

thing we need to do in preparation Slip Stream SQL 2008 SP1 onto the SQL Server 2008 RTM install media.

Slip stream SQL SP1 onto your SQL 2008 install media

What I have discovered is that SQL Server 2008 will not install on Windows Server 2008 R2 without first

slipstreaming SQL Server 2008 SP1 onto your SQL 2008 install media. Here is a great article that describes how to

slipstream SQL Server 2008 RTM and Service Pack 1. After I read that article and successfully slipstream SP1 onto

SQL 2008 RTM, I found the following Microsoft KB article that describes the same procedure. You may get an error

that looks like the following if you try to install SQL without first slipstreaming SP1 onto the media.

SQL on a multi-node cluster, you must first pass the Windows Server 2008 Failover Cluster validate process.

Unfortunately, a multi-site cluster is exempt from passing the storage related test, so you never are able to actually

pass the validation as far as SQL is concerned. It took a little investigation on my part, but what I have come to find

is that there is a command line parameter that allows you to skip the validation test on the SQL 2008 installation. Here

is the command line.

Setup /SkipRules=Cluster_VerifyForErrors /Action=InstallFailoverCluster

To launch the SQL setup, open a Command window, browse to your SQL 2008 with SP1 install directory and type

the command as shown below.

If everything goes as planned, you should see the screen below. Click OK to continue.

Enter your product key and click Next



19/64

Figure 17 Enter your product key

Accept the license agreement and click Next



20/64

Click Install to install the Setup Support Files



21/64

At the end of the Setup for the Support Files you will receive a warning. Click on Show details and you will see the

message below. You can click Next, ignoring this message since it is expected in a multi-site or non-shared storage

cluster.

23/64

Figure 19 Choose your features

On the next screen, you will choose a network name for your SQL Server. This will be the name that all of the clients

will connect to. Assuming this is the default instance, leave the Instance ID and Instance root directory set to the

defaults. Do not move the instance root directory to the replicated volume.



24/64

Figure 20 Choose your SQL Network Name

It is recommended that you have separate domain accounts for SQLServer and SQLAgent. You can take the time to

create these accounts now if you have not already done so. These accounts require no special permissions, as this

install process will give them the permissions that they require.

Confirm you have enough disk space and click Next to continue.

Choose the default settings to allow a new cluster resource group named SQL Server (MSSQLSERVER) to be

created.

32/64

You will once again see some warnings related to the validation process. You can ignore those messages as they are to

be expected in a multi-site SQL Server cluster.



33/64



34/64

If everything installs as expected, you should see the following screens. Click Next then Close to finish the installation.



35/64



36/64

Congratulations, you have successfully installed the first node of your multi-site SQL Server Cluster. Now we will

install the second node of the cluster.

Install the second cluster node

Installing the second cluster node is similar to installing the first node. We need to run SQL Setup once again from the

command line so that we can skip the Validate process. So, from the 2nd node, open up your command prompt and

run the following command.

1 Install SQL 2008 SP1 (merged set p) on the 2nd node sing the follo ing command:



37/64

That will launch the install wizard as shown below. Click OK to continue.


Enter your product key and click next.


38/64

Accept the license terms and click Next



39/64

Click install to install the Setup Support files.



40/64

You can once again ignore the warning that some cluster validation tests have been skipped. This is to be expected in a

multi-site cluster and non-shared storage clusters.



41/64

Verify you are adding the node to the righ instance and click Next.



42/64

Add the passwords to the service accounts and click Next



43/64

Choose your Error and Usage Reporting options and click Next



44/64

Once again, ignore the warning about the skipped operations.



45/64

Click Install to begin the installation process.



46/64

If everything goes as expected, you should see the following screen.



47/64

Now that you have a fully functional two node cluster, you probably should testing things out by doing some manual

switchovers. Right click on the resource and choose Move to node SECONDARY.

ConclusionI believe that SQL clusters with replicated storage make a lot of sense. Storage has always been a single point of

failure of traditional clusters. You can eliminate that single point of failure by deploying a SQL Server cluster with

replicated storage from SteelEye or any other Microsoft Multi-Site Cluster replication partner. I hope you found this

article informative. If you have any questions or suggestions, please add your comments!

Hi,

I am having Two SQL Server Sites, having one node on each site and using HP XP24000 as storage solution

with Cluster Extension, XP24000 is providing the drives on each node (i.e. replicated drives not shared drives),

so I omitted the Storage tests while creating Windows Cluster, and installed SQL Server Failover Cluster on

Active node by bypassing the Failover Cluster verifications. SQL Server setup completed on Active node

successfully.

But the SQL Server setup fails during disk qulifications check when I am trying to add the passive node to the

SQL Server Cluster, as the SQL Server Setup investigates the disks and dependent resouces on disks. I have

also removed the disk dependcies using Windows Failover Cluster Management and all disks are also in same

group.

There is only once difference from your steps of adding node is that I add passed following parameter

(mistakenly) while adding the node.

Setup /SkipRules=Cluster_VerifyForErrors /Action=InstallFailoverCluster

Can you please suggest me something on this problem?

daveberm said, on October 14, 2009 at 6:26 pm

I think the command line you used should work. So are you failing on the wizard screen Cluster Disk

Selection? If so, do you see the disks at all in the Available shared disks: panel? If not, then you may

have done something wrong in terms of setting up the replicated storage. I am not familiar with the Cluster

Extension XP, but it looks like page 100-130 ofthis manual have the instructions you need to add the XP

Resource to your cluster. Unfortunately, if you have not already done this and used a basic Volume

resource for your first node, I believe you will want to unistall SQL on the first node and start over fresh.

Im sure HP may be able to give you some guidance if you get stuck.

While adding the node B into the FOC of node A, SQL Server Setup checks the shared disk check at

Setup Support Rules step.

- As its mentioned in multi-site cluster documentation, we dont need to have shared storage then why does

SQL Server Setup is checking up the Shared Disks?

- How can I bypass Shared Disks check?

- Is it because I add mistakenly executed the setup with wrong parameter?

Thanks.

Have you read the manual for your storage? I have not used your storage device in a multi-node cluster,

but from what I understand it looks like you need to add the Cluster Extension XP resource type to

WSFC. It is not 100% clear to me how this plays into the configuration of your cluster, but it looks like it

may be dependent upon the Volume resource. Your best bet it to get an HP storage specialist on the

phone to help you out

From what you told me, I would expect the results you are seeing. If you assign a volume to NODE1 and

a different volume to NODE2 then I would expect SQL add-node to fail because the storage used on

NODE1 is not available on NODE2. There has to be some way (provided by HP) to trick SQL into

thinking the volume on NODE1 is also available on NODE2. SteelEye does this by replacing the Physical

Disk resourc with its own cluster resource that looks and feels like a Physical Disk, but is actually a

replicated volume resource that controlls I/O fencing and mirror diection. I am not sure how HP does

this. If there is anyone out there reading this who knows, please feel free to comment. Or if anyone wants

to send me some free HP storage arrays with Cluster Extension XP, Id be glad to write up a step-by-

step guide for multi-site SQL clusters using HP XP storage

Great article. Just what I needed to help plan a proof of concept.

I do however have one question in the case of a failover to a remote site, how do you fail back? ie. In this

example, your data is synchronised from the primary server to the secondary server, but during a fail over when

you are working on the secondary server, how do you get your changed data back to the primary server when

you are ready to fail back?

Thanks,

Gareth

daveberm said, on September 16, 2010 at 3:32 pm

Gareth,

In the case of DataKeeper as soon as the failed server comes back online it assumes the role of mirror

target and a partial resync begins automatically. Basically while it is offline the source of the mirror

tracks the changed blocks in an intent log, so when the failed server comes back online just the changed

blocks are sent. Once all the changes are sent the mirror goes back to a normal mirroring state and youcan then bring the original server back online via the Failover Cluster GUI.

Biggest problem usually involves bandwidth. You just want to make sure your bandwidth can handle your rate

of change. Second issue is quorum settings. In order to facilitate automatic failover to the remote location you

must deploy an even number of cluster nodes and you must locate your file share witness in a 3rd location.

Very good series. Question, What is the main difference between installing SQL Server 2008 multi-site cluster

and installing one instance of SQL 2008 on one VM server within a failover cluster? I have done that and it

seems to work very well. When I failover the VM server housing the SQL server theres no user impact. Im

not a SQL expert so Id just like to know the significant differnce. Thanks

I blogged about the difference between clustering SQL and clustering at the VM layer here.

This should tell you everything you need to know, if not Id be glad to answer any questions.

Data) on a Compellent Dell SAN. OS is Windows Server 2008 R2 sp1, SQL Server 2008 sp1.

Is it possible to install SQL cluster on those instances? I have tried to setup these instances with cluster but it is

installing a new instance of SQL

Can I have two storage resources for same SQL cluster instance?

Reason I am asking is because we have two LUNs, one for Logs and the other one for Databases; and on the

setup it allowed to add only one storage resource (SQL cluster process, for windows everything goes fine).

Last question: I have a SQL server located geographically far from the cluster, whitch has been configured with

same instances and mirrored databases. Can I have Windows SQL server 2008 mirror setup from the cluster to

this server? If the cluster fails over to the other server; would it brake the mirror?

Any help would be much appreciated.

You cannot convert existing instances into clustered instances, you must install new clustered

instances and migrate the databases to the new cluster.

Yes, you can add a second volume resource after the cluster is created and move the log files

to this volume

Yes, this is a common configuration and will work without breaking the mirror.Any help would be much appreciated.

y y Q , g g pp g,

mirroring, transaction replication and peer to peer replication as you mention. Each solution has strengths

and weaknesses, so you have to understand exactly what you want to do. A multisite SQL Server cluster

as described in this article is going to give you the most complete protection as it replicates the entireSQL instance. Most of the other techniques I mention replicate at the individual database layer.

The other factor you have to consider is client redirection. With a multisite SQL Server cluster client

redirection is automatic and supports any application as the SQL instance name is moved between cluster

nodes. The other replication methods are not as robust in terms of client redirection and not every

application is going to work in these environments. Of these other methods Database Mirroring comes

the closest in terms of automatic failover and client redirection, but it does have limitations such as lack ofsupport for SQL instances that use distribute transactions. Even the new SQL Denali HADRON does

not support databases that use distributed transactions, although it does offer some pretty significant

enhancements and is worth investigating.

Peer-to-Peer replication is not something that I would consider as an option for high-availability as writes

are generally limited to one of the nodes. If that node goes away you have to reconfigure your application

and your peer-to-peer replication scheme. In general Peer-to-Peer replication requires a lot more thought

and planning vs Database Mirroring or Log Shipping, which are much better suited for simple database

replication.

Much appreciated your response; it saved me lots of wondering.

So far I have installed one SQL instance (clustered) with a mirror to another server.

Now I have three instances to setup in the cluster, and I am still on the process of gathering information and best

practices prior deploying it to a production environment.

Questions: How large should be each MS Dtc LUN (one for each SQL instance)? Ex: For an instance 500 GB

Dave, first off WONDERFUL article! I very much appreciate your sharing the brain dump.

One thing that I thought you may like to know, that will save you an added step and a bit of time,and that you didnt really cover, is setting the SQL Server clustered service General and Failover

parameters on the First node, BEFORE your section Install the second cluster node.

ON the PRIMARY (First) NODE (after the Your SQL failover cluster installation is complete message)

1) Go to the Windows Failover Cluster Manager and modify the SQL cluster service

2) Under Services and Applications, Highlight SQL Server and Right-click

3) Select Properties, and then, on the General tab, under Preferred owners,4) Put a check-mark in both nodes (ensure PRIMARY node is listed 1st as preferred owner)

5) Ensure the service is set to auto-start

6) Click Failover tab

7) Choose Allow failback button, and Immediately button IF that is right for your environment

[WARNING: IF you are using replication across the WAN, tune these as desired,

Example: Leave "Prevent failback" selected, since you likely want to do "manual failback" in the WAN]

This will make install of the second node easier/faster, as it will form a portion of the SQL Cluster,

(Yes, even before SQL is installed on the 2nd node), making the 2nd node aware

of the already-existing Service Account settings from the 1st/Primary node.

Saves you some time and effort from having to re-enter the accounts/passwords on the 2nd node.

17. Jeffsaid, on August 11, 2011 at 2:44 pm

I stand corrected the password information doesnt get passed through, but the accounts are recognized; so it

still appears to pass through some of the information saving the re entering of the accounts themselves


network binding order. BUT, even after you correct the binding order (via a HIDDEN Alt-N command in

Network and Sharing Center, Change Adapater Settings), AND then you fully reboot everything, STILL the

binding order is reported as incorrect clearly a Microsoft bug.

IsDomainNetworkTopOfBindings Checks to see if the computer domain server is on the network that is

bound to the top of the network order. Warning The domain network is not the first bound network. This will

cause domain operations to run slowly and can cause timeouts that result in failures. Use the Windows networkadvanced configuration to change the binding order.

There may be a registry fix or SP for this (have yet to put SQL 2008 R2 SP1 on will do that in a few

moments).

Hello DaveBerm, very good Article.

I was trying to see the limites of such architecture.

The volume rplication using SIOS DataKeeper is a 1 to 1 replication design. Which means that the cluster is

limited to 2 nodes if using local drives at each site. am i right?

Second question: imagine i have 2 nodes on one site using shared volumes and another 1 node on the other site

with his own volume. How can i setup the replication from shared volume to the single? and above all i wonderhow the failover and failback will proceed?

These questions are mainly about scaling out in order to provide high availability from a local site perspective

first, then intregrated with Disasster Recovery and still High availability.

Thanks for the note. This article illustrates a 1 to 1 design, but by no means is that the limits of the

application. DataKeeper supports multiple targets, so you could build 1 x 1 x 1 x 1 type designs. It also

supports a mixed shared/replicated model, so you can build 2 x 1 or 2 x 2 type models as well. Ive

written about other configurations in some of my other articles. Here is one of those articles:

Hi,

what happens if i create my own custom resource group name instead of letting SQL create it for me?

Ive never tried. What is wrong with the default name? If you do it, let me know how it works out for

you.

Thank you for the post. My first Geographically Dispersed SQL Server Instance (GeDiSSIn in short) is up and

running. Im using SteelEye for my supporting database servers (Distributor, Mirror Witness and General DBA

Management Instances) as Microsoft does not have a way to mirror the distributor database and/or the mirror

witness functionality.Regards

Does a SQL Server 2008 R2 geo-cluster (multi-site cluster) is possible with Standard Edition?

Node 1 is a SQL replication publisher doing Merge, Transact, and Snapshot to its subscribers. In the event of

failure, Node 2 will become the publisher to those same subscribers.

What SQL files will I need to replicate with SteelEye DataKeeper Cluster?

The MDF, LDF of the all databases, and the distributer DB? Is that it?

All of the system and user defined databases and log files should reside on the replicated volumes, same

as a traditional shared storage cluster.

Excellent Post! Thanks alot.

But Instead of Data Keeper can I use any alternate which is freely downloadable or any thing offered by

Microsoft.

daveberm said, on January 18, 2013 at 2:42 pm

Microsoft does not have a host based replication solution for clustering nor is there anything freely

available for download.

Why can't people understand that 2-node cluster with no witness (disk or otherwise) is just a bad idea.
