Recovery :: Server Cluster Installation
Aug 24, 2015
I am learning SQL Server failover cluster installation. My question is regarding the options to install failover cluster instances on the Windows Failover Cluster. I have seen ead there are two options to do so.
From the installation center, installation option-> New SQL Server installation option and afterwards add node to SQL Server failover instance.From Installation Center, Advanced option-> Failover cluster preparation and then Failover cluster completion step.What is the difference between these two options and which option to use in which scenario?

I want to install service pack 3 to my SQL Server 2012 Enterprise running on windows server 2008 R2 Enterprise fail over cluster, I read about the SP installation in technet, its mentioned that the passive node should be patched first and to do this the passive node should be removed from the cluster, I need to know whether I should completely remove the node from windows cluster or remove the node by using SQL Server installer and install the service pack and then add it back to the cluster, Can I do this by pausing the node in cluster and perform the service pack installation ?

We have a requirement to build SQL environment which will give us local high availability and disaster recovery to second site. We have two sites- Site A & Site B. We are planning to have two nodes at Site A and 2 nodes at Site B. All four nodes will be part of same Windows failover cluster. We will build two SQL Cluster, InstanceA will be clustered between the nodes at Site A Server and InstanceB will be clustered between the nodes at Site B, we will enable Always On Between the InstanceA and InstanceB and will be primary owner where data will be written on InstanceA and will be replicated to InstaceB. URL....Now we want we will have instanceC on the Site B and data will be writen from the application available on Site B, will be replicated to the instance on the Site A as replica.

can we join a node in a windows cluster which is already in a different cluster?
We have this requirement as we need to setup readable secondary ( always on AG) on the third node.

We are planning to change all IPs of PRODUCTION Failover Cluster Setup. In my cluster setup ... we have 2 Physical Nodes with windows-2008, Roles are MSDTC and SQL-2008R2.
IP change for:
1. Both Nodes(Physical)
2. MSDTC
3. SQL ServerÂ
4. windows ClusterÂ
So Almost... All IPs are going to change.
Im DBA here, I need to take care of SQL cluster and MSDTC. But I haven't performed this activity before.So I'm worrying about Impacts and consequences of this change. steps how should I perform this activity.

During the installation of Adding node to a SQL Server failover cluster(On passive node) getting error like.. The MOF compiler could not connect with the WMI server. This is either because of a semantic error such as an incompatibility with the existing WMI repository or an actual error such as the failure of the WMI server to start.We  run the below commands but didn’t get any resolution & got the same above error .
Â
1<sup>st</sup> Method…
1. Open console command (Run->CMD with administrator privileges).Â
2. net stop winmgmtÂ
3. Rename folder %windir%System32WbemRepository to other one, for backup purposes (for example _Repository).Â
4. net start winmgmt

I have an urgent query that we are running SharePoint server 2013 on single server and installed SQL server 2012 on single server, our management decided that we need to configure failover cluster on existing SQL server. I want to confirm that it is possible that we can install failover clustering services on existing SQL server and then add an other server on SQL 2012 for high availability or do we need to first install failover cluster service and then install SQL server for failover clustering.

Hi,
A few months ago, I was trying to install SQL Server 2005 SP2 on a cluster (Active-Active), the Cluster has 3 instances, 2 lives in one node and the other one in the other node. When I try to make the deployment an error message appear, I do not have the error right now but it€™s something like €œCould not connect to the passive node, installation failed€?. The worst part of the error was all instances shut down and I couldn€™t bring on line and I have to reinstall all instances. I need to install SP2 but I€™m a little afraid fail again. Do you know the best way to deploy the SP2 on a cluster? Maybe move all instances in one node before install SP2? Can you help me with your comments. Do you think I have problems with the windows cluster?
Thanks and Regards,

When adding a node to a SQL Server 2012 Standard edition cluster, how I do I identify the location for SQL server shared components and the rest of the SQL Server installation binaries?
When adding a node to a SQL Server 2012 Standard edition cluster all the binaries went to the C: drive default location. We put those files on a different drive when installing the first node. What needs to be done so both nodes have the binaries on the same drives and folders?

I have a Windows 2003 Enterprise x64 edition cluster setup and functioning normally. Now, I am trying to get SQL Server 2000 installed as a failover cluster but am having some difficulty. When installing, I get the message '[sqsrvres] ODBC sqldriverconnect failed' in the event log. The message happens when the installer is trying to bring the SQL Server Service resource online.
I am able to ping the name of the instance successfully. I am able to manually start the 'MSSQL$InstanceName' service. I have turned off the firewall on both machines, but this did not help. I have the DTC Service setup as a resource in the same cluster group.
I also read http://support.microsoft.com/default.aspx?scid=kb;en-us;815431 which seemed promising, but did not reolve the problem.
Any help would be much appreciated.

Hi All,
We have been experiencing issues with SQL Server 2005 SP2 upgrade on cluster servers.
After running the setup, it gives failure message for Database services.
Installing SP2 on 64bit cluster server we get error regarding "passive node not patched properly or run the setup from passive node". However, select serverproperty(€˜productlevel€™) returns the output as "SP2". On more digging we found from SQL Server Error log, that the resourcedb of that server is of level 9.0.0.3199
€œThe resource database build version is 9.00.1399. This is an informational message only. No user action is required.€?
However if we do the SQL Server 2005 SP2 upgrade on standalone machines with the same software repository, it upgrades successfully and also resourcedb upgraded to 3042 version. So if we look at the errorlog of a standalone machine it gives following message.
"The resource database build version is 9.00.3042. This is an informational message only. No user action is required."
I again reiterate that, this is the issue we have faced on 64bit SQL Server 2005 SP2 upgrade only on cluster SQL Servers, however on standalone machine it works fine and 32bit SP2 installation works fine.
Please let us know the solution for this.
regards
Jay Mehta

Hi Everyone,
I have problem when installing SQL 2005 Enterprise to my Windows 2003 R2 cluster. I install the SQL instance on the first node in my cluster, it analyses the cluster and comes up with no errors or warnings, i answer all the installation questions and proceed with the installation. When installing the SQL engine I see the status changing as the instance is started and then stopped again etc, finally the status changes to "removing backup files" when it get an error that reports:
"The setup has encountered an unexpected error while Completing Commit. The error is: The specified module could not be found."
Unfortunately there isnt any more information to go on. Any help would be appreciated.

Due to a SQL 2014 cluster installation failure related to security while setting up the primary node, I had to remove the node and any related installation programs from the node and redo the installation again. However I am unable to use the machine name as the SQL network name during the instance configuration, I get the following:
Microsoft.SqlServer.Chainer.Infrastructure.InputSettingValidationException: The SQL Server failover cluster instance name "MachineName" already exists as a server on the network. Specify a different failover cluster instance name.I am still getting the same name since the node name "MachineName" is listed under the cluster name. I have used machine name as SQL network name without an issue. I do not have any existing SQL machine name in network using same machinename which I want to use for this installation.

The SQL Server service failed to start. For more information, see the SQL Server Books Online topics, "How to: View SQL Server 2005 Setup Log Files" and "Starting SQL Server Manually."
The error is (17058)

We have SQL cluster installed on top of windows cluster on VM environment. Node1 and Node2 under Windows Failover Cluster. SQL instance is currently on node2 the instance is up and running, but SQL Cluster service remains online pending and it restarts the instance on every 5 minutes.
SQL Browser service are running successfully.TCP/IP ports are enabled and configured.If we start the SQL server agent it is on for seconds and stopped immediately  .Cluster Service is attempt to connect to the SQL service every few minutes (setting in SQL cluster resource) for the IsAlive check, if this fails then the SQL resource is restarted even if the instance was online. Hope this is what happening exactly.

We have an HA configuration with an Active-Passive Cluster / Shared Disk SAN which is working great. Â I have been looking for how to replicate the information to our DR site. Â We have many databases (some are more static vs. other transactional). Â I had some questions:Would it make sense to configure a snapshot for the static databases? Â Is that possible from a clustered environment using it as the publisher?Would it make more sense to configure the clustered environment to use transactional replication? Â Is it possible from a clustered primary?Is log shipping too archaic?

Cluster services gives the high availability needed - that is great.But I have never seen any discussion about what happens when a nodefails - what do you do to get everything back to the active-passivetandem.I imagine there is not much difference in terms of recovery procedurefor either active or passive node. So I'm just going to make up ascenario that we have encountered. The system hard drive (not theshared disk) on primary node fails. Cluster fails over to the passivenode. Following are the problems I have at hand:-After installing windows, I need to install driver and configure thepermission to access the SAN. There is no way I could do it since thesecondary node has exclusive access to the disks.-Imagine I got that working, is there anyway to install SQL so SQLwould know this server used to be the primary node and attach the DBand translog automatically-Finally, there is no proper way to apply SQL 2000 service pack 3a.Originally when the cluster was fully functional, the service pack wasapplied to active node and that automatically upgrades passive node.Now we have a machine without 3a and a machine with 3a alreadyinstalled. See any problem?Consider all of the above as this one big question: What is a properprocedure to restore a cluster when one of the node goes down? Whetherit's the active or passive node.

I have inherited two separate SQL clusters. One cluster instance is called DESQLSC1INST1 and the other is MKSQLSC1INST1.
On MKSQLSC1INST1 I can connect by using MKSQLSC1INST1, MKSQLSC1 and the IP address that the cluster is running on.
On DESQLSC1INST1 I can only connect using DESQLSC1INST1.
I have checked configuration manager but it does not show me how this is set up.
Is there another way to configure this?

We have 2 clusters, 1 running SQL 2008 on Windows 2008 R2 server and 1 running SQL 2000 on Windows 2003 Server. Because of a disaster with the disks, each of the passive nodes had to be rebuilt and Ive been asked to install SQL on the nodes.
Ive not done this before. Does this mean simply adding a new node to the cluster through the wizard? Or do I need to reinstall the entire cluster?
I think SQL 2000 is too risky as its unsupported, so Im going to resist that. But how should I approach the SQL 2008 Instance?

"The address 10.10.10.111 is not valid for its associated network"
I'm following the instruction in the book for the 70-462 exam. Â There was a step that had me create a DNS A record for the address sql-cluster.contoso.com. Â The IP address was mapped to 10.10.10.111. Â I'm not sure if this is the culprit but its the only time I used that IP address in the setup.

I saw following point on Technet article about RBS.The local FILESTREAM provider is supported only when it is used on local hard disk drives or an attached Internet Small Computer System Interface (iSCSI) device. You cannot use the local RBS FILESTREAM provider on remote storage devices such as network attached storage (NAS).It looks like that we cannot use FILESTREAM on Failover Cluster because to setup Failover Cluster we need to have NAS. But then the NAS is made available locally for Failover Cluster so FILESTREAM should work right?Found another article which talks about setting up FILESTREAM on Failover Cluster. URL...

The main objective is to have a third party program operate on a failover cluster. The OS is Windows Server 2012 Datacenter loaded on 2 nodes. A virtual node exists along with supporting disks. This client software uses a SQL Server database. SQL Server 2012 Enterprise is installed and operating in a failover environment. However the client software is not failing over. If the connection to node A is lost, SQL Server fails over to node B. But the client application does not.Â
What needs to occur in order to associate the client software with the failover cluster? This software has 6 services total installed. Some are referred to as servers - looks like to communicate between remote client computers and the database. What is the process to associate the client software with the failover?

I have had a serious issue with a production AlwaysOn cluster whereby the service did not successfully transition to the secondary node and I cannot find the root cause of the issue.
Some details: It is a 2 node cluster (same datacenter) with a shared disk quorum, Windows Server 2012, both are virtual machines running on VMWare vSphere  5.5. SQL Server version is 2012 Enterprise SP2 CU6
The failover occurred because of a network incident (a spanning tree recalculation caused a connection timeout between both nodes). Initial entries in the SQL Log look normal for this event, for example:
05/08/2015 11:18:06:Â A connection timeout has occurred on a previously established connection to availability replica 'FIN-IE-PA078' with id [6910F4A9-87E7-4836-BA79-0F41BE90266D]. Â Either a networking or a firewall issue exists or the availability replica has transitioned to the resolving role.
05/08/2015 11:18:06:Â AlwaysOn Availability Groups connection with secondary database terminated for primary database 'UserManagement' on the availability replica with Replica ID: {6910f4a9-87e7-4836-ba79-0f41be90266d}. This is an informational message only. No user action is required.
[code]....
My interpretation of this is that the cluster failover attempts failed, because the network condition still persisted. The network interruption lasted approximately 2 minutes, and I would have expected the cluster to come back online at this point, after the restart delay period as suggested in the last entry in the error log. However this did not happen.

we have to build high availability SQL 2012 cluster for VDI and we have two options. One option is to build a server cluster with combination of failover and mirroring and other option is to build failover cluster with AlwaysOn.We are not sure which option to chose. We have contacted Microsoft support to provide us some documents and instructions for failovermirroring combination but they have send us instructions for AlwaysOn option.
What would be best way to build high availability cluster for VDI? Also, since first option is very complicated.
