SQL Server cluster installation checklist

List of checks you may need to perform before you install SQL Server Cluster.

1. Verify your system meets the minimum requirements
910228 SQL Server 2005 Readme and installation requirements
http://support.microsoft.com/default.aspx?scid=kb;EN-US;910228
907284 Changes to the readme file for SQL Server 2005
http://support.microsoft.com/default.aspx?scid=kb;EN-US;907284
327518 The Microsoft support policy for a SQL Server Failover cluster – Please note that ONLY Microsoft Failover Clusters are supported.
http://support.microsoft.com/default.aspx?scid=kb;EN-US;327518
SQL Server 2008  Before Installing Failover Clustering
http://download.microsoft.com/download/4/5/3/453739ed-cb74-46b1-b7af-f157ee71db20/SQL2008Readme.htm.
http://msdn.microsoft.com/en-us/library/ms189910%28v=SQL.100%29.aspx

2. Log on as an Administrator.
SQL Server 2005/2008:  Log on to the cluster node as a domain administrator that is also local administrator on all nodes, but not necessarily an account that is to be used as a service startup account for the SQL Server services.

Pre create user groups in active directory for different SQL Server 2005/2008 services(SQL,Agent,FT).SQL Server setup will add the service accounts of SQL Services to this groups during setup. You have to pre create unique group name for each Service in AD and enter it when prompted during SQL Server2005/2008 Cluster setup.
SQL Server Setup grants the following Windows NT rights and privileges to the Group you enter during setup (If you can not run the setup as domain administrator then add the service logon accounts to the security groups created in AD before the setup).
For SQL Server group
Log on as a service (SeServiceLogonRight)
Act as part of the operating system (SeTcbPrivilege) (only on Windows 2000)
Log on as a batch job (SeBatchLogonRight)
Replace a process-level token (SeAssignPrimaryTokenPrivilege)
Bypass traverse checking (SeChangeNotifyPrivilege)
Adjust memory quotas for a process (SeIncreaseQuotaPrivilege)
Permission to start SQL Server Active Directory Helper
Permission to start SQL Writer
and many more
For  SQL Server Agent group
Log on as a service (SeServiceLogonRight)
Act as part of the operating system (SeTcbPrivilege) (only on Windows 2000)
Log on as a batch job (SeBatchLogonRight)
Replace a process-level token (SeAssignPrimaryTokenPrivilege)
Bypass traverse checking (SeChangeNotifyPrivilege)
Adjust memory quotas for a process (SeIncreaseQuotaPrivilege)

3. There should not be a pending Reboot requirement

Check pending Reboot requirement in following registry:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager
In the right-hand pane, is there a value of PendingFileRenameOperations?  If so, is it empty?
If empty close the registry editor.  If not empty, reboot the machine prior to running setup.  After logging in, re-check this registry value to make sure it is empty.

4. Verify Cluster “Heartbeat”
For a Failover Clustered Instance installation on Windows 2003 or earlier, verify cluster networking was setup per:
258750 Recommended private “Heartbeat” configuration on a cluster server
http://support.microsoft.com/?id=258750
NOTE: This needs to be followed explicitly in regards to the binding orders and your heartbeat adapter’s configuration.

5. Verify the TCP\IP Advanced DNS settings are identical on the “Public” network adapters between all Failover cluster nodes

6. Stop All Non- Microsoft Services  Excluding services required by SAN or network adapters online

7. Make sure  below services are running on all node’s
Cryptographic Services <====This must be running on all nodes.
DNS Client
Event Log
Remote Registry Service <====This must be running on all nodes.
Task Scheduler
Windows Management Instrumentation Driver Extensions
Windows Management Instrumentation

8.  Flush Cached DNS Entries
Flush the DSN cache.

Ipconfig /flushdns
then… Referesh te netbios name registered
Nbtstat –RR

9. Verify Logon Server
Open a command prompt on each node and enter the command:

set logonserver

Verify if logon server is same on all nodes.

10. Verify Admin Shares
IPC$
C$
Admin$
DriveLetter$
DriveLetter = Disk in which you have setup files.

Use the “Shared Folders” MMC snap-in  to verify the existing Administrative shares.

11. Only One RDP Session

Make sure no one else is logged in to any of the nodes. There should be only one logon session in active node which we use for setup.
12 . Make sure we are able to failover SQL Server groups to all nodes.

13. Cluster MSDTC
Create MSDTC resource.

14. If windows2008+ Grant  “Create Computer Objects” permission for  the computer object created for the cluster  (Computer Name object(CNO)).

http://mssqlwiki.com/2009/03/26/installation-of-sqlserver20052008-fails-on-windows2008-cluster/

15. For Windows 2008, see How to configure DTC for SQL Server in a Windows 2008 cluster http://blogs.msdn.com/cindygross/archive/2009/02/22/how-to-configure-dtc-for-sql-server-in-a-windows-2008-cluster.aspx
Use the following KB article to Cluster MSDTC if not already clustered on Windows 2003:
301600 How to configure Microsoft Distributed Transaction Coordinator on a Windows Server 2003 cluster
http://support.microsoft.com/default.aspx?scid=kb;EN-US;301600

16. Grant Read SPN and write SPN permission for startup account of SQL Server (or) Security group provided during installation for SQL Service startup account.

17) Verify Dependencies http://support.microsoft.com/default.aspx?scid=kb;EN-US;835185

HOW TO INSTALL SQL Server CLUSTER IN HYPER-V

To install SQL Server failover cluster we need to have windows cluster configured with a shared disk.

Step 1

If you do not have a windows cluster configured you can create using Hyper-v

Follow the steps in HOW TO CREATE CLUSTER USING HYPER-V to create Domain controller and two member servers which will act as nodes of the cluster.

Once the domain controller and two member servers are created proceed to step 2

Step 2

Once the domain controller and nodes are created install failover cluster feature and create cluster 

To install the failover cluster feature and create a cluster follow the steps in How to install cluster in windows 2008 and windows 2012

Step 3

Once the cluster is created we have to create shared Disk for installing failover aware clustered application like SQL Server.

Follow the steps in ”How to create shared disk using iSCSI Software Target” to create a shared disk using iSCSI target software.

 

Once shared disk is configured invoke Setup from  SQL server installation media .Make sure the node in which you perform the  installation has shared disk online.

How to create shared disk using iSCSI Software Target

One of the mandatory requirement to install SQL Server and similar application in cluster is to have shared disk.

I will explain how to create shared disk using iSCSI software target in this blog. You can download iSCSI Software Target from This link.

Installing Microsoft iSCSI software target.

When you invoke the self extracting package from downloaded above link it extracts  X64 and x86 version of installer.

  • Select iSCSI_target  for installation on the system which will act as iSCSI target. We will create iSCSI target disks in this machine and these disks will be shared by nodes using iSCSI initiator.
  • Select iSCSItargetClient_public and install in nodes in which you would like to have shared disk probably all nodes which is going to be part of cluster you are installing.

 

INSTALLATION IN CLUSTER NODES:(Follow same steps in all the nodes which will be part of cluster which you are installing)

Install iSCSItargetClient _public in all nodes which are going to be part of cluster which you are installing .

Run the file to start the installation.

clip_image001[6]

Click Next and continue

Select the type of installation as Typical.

clip_image001[12]

Specify users account that is member of administrators group in system which is acting iSCSI target and iSCSI initiator (current system).

clip_image001[16]

Configure other settings.

clip_image001[18]

Start the installation by clicking Install button.

clip_image001[20]

 

clip_image001[22]

 

Click finish to complete the installation

 

Install the  iSCSI_target on the system which will act as iSCSI target probably file server (or) Domain controller if you are installing failover clustering for testing.

 

CONFIGURE iSCSI INITIATOR IN CLUSTER NODE’S:

After installation,Open ISCSI initiator.

clip_image001[24]

  • Select yes  and continue.

clip_image001[26]

  • Type the target server name and click on Quick Connect

clip_image001[28]

                                       (Or)

  • Click Discover panel and select the target sever.

 

clip_image001[30]

  • Give the server IP address.Click ok.

clip_image001[32]

Similarly Follow the above steps and select the target in all nodes of cluster.

 

Configuring iSCSI target

Now after selecting the target,we have to add the all the iSCSI clients in iSCSI target.

Open MS iSCSI Target in system which is acting as iSCSI target.

 

clip_image001[34]

Right click iSCSI target->create ISCSI target.

clip_image001[36]

Create target wizard will open.

clip_image001[38]

 

Specify the target node name,click Next.

clip_image001[40]

Browse and select the iSCSI initiator,click ok. 

clip_image001[42]

Selected initiator will appear.Click Next.

clip_image001[44]

Click Finish and complete the target creation.

clip_image001[46]

Target Node1 is added.

clip_image001[48]

Follow the above steps in all nodes.

 

CREATING VIRTUAL DISK FOR  ALL NODES:

To create virtual disk in iSCSI target right click Node1->Create virtual disk.

Click Next.

 

clip_image001[52]

Specify the file name which will be used as virtual disk.Specify it with .vhd extension.Click Next.

clip_image001[54]

Specify the size for your virtual disk.Click Next.

clip_image001[56]

  Click Finish.

clip_image001[58]

For node2,Right click Node2->Add Existing virtual disk to iSCSI target.

clip_image001[60]

Click OK.

clip_image001[62]

CLUSTER NODES:

Now after adding the nodes as target in DC,we have to initiate the server in cluster nodes.

Select iSCSI initiator.Click Refresh,if you didn’t get any discovered target.

clip_image001[64]

Select the target  and connect it.Click OK.

clip_image001[66]

Open Disk management in cluster nodes:

clip_image001[68]

Right click Disk1->Online

clip_image001[70]

  Again ,Right click Disk1->New Simple Volume.

clip_image001[72]

New Simple Volume Wizard->Format this volume with the following setting.Click Next.

  clip_image001[76]

Then Finish the setting.

 

Open Failover cluster manager.Expand SQL Cluster.mssql.wiki.com.

Storage->Add a disk.

clip_image001

Click OK and add disk to a cluster.

clip_image001[4]

Disk is added. (If disk is created for one node,automatically it will be shared by other node)

clip_image001[8]

 

Now the shared disk is ready for use and can be used for installation of SQL Server cluster (or) any other cluster aware application which needs shared disk.

How to stimulate a SQL Server resource failure in cluster

How to stimulate a SQL Server resource  failure in cluster?

If you like to perform a check in SQL Server cluster to identify if the SQL Server resources are failing over properly follow the below steps. you can use Step 2 to create a SQL Server hang and deadlocked scheduler dump in standalone server as well.

 

 

1.       Create a instance failures scenario by  issuing “shutdown” command to SQL Server which will terminate/Shutdown SQL Server. SQL Server resource DLL in cluster should detect that the SQL Server have failed and start the SQL Server resource automatically.

 

Steps

a.       Connect to SQL Server using an account which has Sysadmin privilege and execute Shutdown command.

 

 

2.       Create a SQL Server hang scenario by creating excessive blocking, once SQL Server exhaust all the available threads SQL Server will stop accepting connections and will go unresponsive. SQL Server resource in the cluster should detect that the SQL Server resource have failed and restart/failover SQL Server.

Steps

a.        Connect to SQL Server and below SQL Statements. (Do not close the session)

 


Create database test;
use test;
create table block  (a char(10));
insert into block values ('Test');
go 10
begin transaction;
update block set a ='Test1'

b. Download the Ostress.exe

c. Execute the following command in ostress.exe

ostress.exe -Sservername\Instancename -E -d test -Q "select * from test..block" -n 2000

Note: Replace servername\instancename with your server name and instance name. Above Ostress command creates 2000 connections and execute “select * from tempdb..block” which will in turn cause excessive blocking and make SQLServer exhaust all the available worker threads.

Is Alive check will fail once the threads are exhausted causing SQL Server to reach hung state. SQL Server resource DLL’s should detect that SQL Server is hung and restart/failover SQL Server.

 If you do not know what is SQL Server LooksAlive and IsAlive Check follow This blog
