SQL 2012 :: Two Node Active / Passive Cluster Installation
May 3, 2015
Few questions on a SQL Server 2012 two node active/passive cluster installation on Win2012.
1. What are the permissions required for the user used to install SQL Server 2012 cluster. Does it need to have any rights on DC or anywhere else apart from the local nodes ?
2. Can we give ANY meaningful name to "SQL Server Network Name" during installation ? Do we need to manually configure it anywhere else before or after the installation ?
3. On what scenarios we need to check/uncheck DHCP check box ?
It is an active passive cluster which doesn’t allow any testing. All instances have to be failed over together, we aren’t allowed to just failover 1 even for testing purposes. Node 1 is the active node and we can failover to node 2 for 30 days free of charge but services have to then be failed back.
We need to run the cluster with node 1 as the primary node always and 2 just use for failover testing or for less than 30 day periods whilst performing cluster patch upgrades etc.
Now l am sure we could fail over 1 instances at a time for testing and diagnosing issues plus if add a new instance that's not production to get to the platform level as the rest of the instances this would avoid taking production down in the fail over process.
I invoke xp_cmdshell proc from inside a stored procedure on a 2-node active/passive SQL 2005 SP2 Standard cluster. Depending on which server the xp_cmdshell gets executed on I need to pass different arguments in the shell command. I thought I could use host_name() function to get the runtime process server, however, I am finding that it's not behaving correctly. In one example I know my active node is server2, but the host_name() function is returning server1. The only thing that I could possible explain this is that the MSDTC cluster group is not always on the same active node as the SQL server group and in the case I am talking about the cluster groups are in this mode (differnet nodes). Does the xp_cmdshell get executed by the SQL active node or the MDTC active node? And what is the best way to find out which server is going to run my xp_cmdshell?
Thanks.
Edit:
Perhaps another by product of this is that if I run select host_name() from the Studio Management query window i get different results depending on which server I am running the Studio Management on. On server1 I get server1 and on server 2 I get server 2, all the while server2 is the active node. I need a different function that will always let me determine the correct server that'll be running the xp_cmdshell...
Edit 2: I guess I could determine the running host inside the command shell itself, but I am curious to see if i can do it (cleaner) from SQL.
We have a SQL cluster server running with SQL 2005 Enterprise Edition SP2 on Windows 2003 Enterprise Edition. Currently the cluster has 2 nodes with Active/Active. Now I need to add a new node as a Passive node. So after I have done it, the cluster will be a Active/Active/Passive cluster.
Because the cluster is a production server, I need to know exactly how I add a new node onto the current cluster without breaking anything. Also this is my first time to install a passive node, so it is difficult for me to understand how to install and configure it.
I have already added the physical node onto the cluster group so I can see the new node €˜paused€™ from the Cluster Administrator. Now I need to install the SQL but I am too nervous to run the installation program.
My questions are:
1. Do I need to run the SQL install program from one of other active nodes in order to install the SQL on to the new node? Or is it ok to run the SQL install program from CD? 2. Do I need to create a new virtual name, a new SQL named instance and a virtual IP address for the new passive node?
Physical node name Virtual name SQL Server Instance Name IP address Node1 (active) SQL1 SQL1 xxx.xxx.xxx.100 Node2 (active) SQL2 SQL2SQL2 xxx.xxx.xxx.110 Node3 (passive) SQL3??? SQL3SQL3????????? xxx.xxx.xxx.120????
3. Is there a risk to delete or change the current active nodes? If so, will you let me know as I will be super-careful not to do it.
I have some doubt about the IP Required for configuring cluster(both Window and SQL server)
Details : ---------- How Many IP(Public & Private) Required for 2 Node Active/Passive both window and SQL server Cluster ?
IP(Public & Private) Required : --------------------------------------- 1 : For Window Clustering : 2 node Active/Passive Cluster ? How many ip ? 2 : For Sql Server Clustering : 2 node Active/Passive Cluster ?how many ip ? 3 : Is there any mathematics for that ? How to analyse the IP requirement ?
Could someone give me an ideal of what it takes to upgrade the memory in my cluster. Is it as easy has upgrading the passive node, switching the nodes, then upgrading the other server. And do I need to re-configure the windows cluster. And will both server need to be down at the same time at any point.
Or is their more to the process? Thanks for any assistance.
This is the 1st time we are building a active/passive cluster with 1 node each. we usually install default instance and setup domain account as service account which will have an spn delegated. Now for active/passive cluster is it ok to use same domain account as service account for both clusters with both creating as default instance again as the windows was built as SERVER1 and SERVER2.
I am having some teething problems while installing SQL on a 3 node cluster. Within the Cluster configuration I have 3 Cluster Groups with each of them having their associated disk resources. All these disk resources physically exist on a SAN.
The actual cluster is running absolutely fine and I can access all the disks from their respective owner node. The problem only starts when I start installing SQL Server 2005 on this cluster. I specify the Cluster group from the Cluster Group Selection and choose the desired partition and then the error message pops up
"There is not enough diskspace on the destination disk for the current SQL Server data files. To proceed, free up disk space to make room for data files, or install the data files to a different drive"
But the disk I am trying to install it on is 264Gb and none of it is used. I have also tried to change it to a different disk within the same Cluster group but to no avail. I have even tried to install it in a different cluster group all together but I get the same error message.
I have googled around havent found anything so far. The disks have got full permissions for the account I am installing SQL with.
In desperate need of implementing a solution where the customer has purchased a CMS to replace their corporate site and wants to use MSSQL as the DB server type. I have 3 servers allocated to me to complete this and I could use some advice on the best setup. THey're running windows 2003 standard server along with sql 2000 standard server. The intended plan is for the 2 servers to become web servers with the last server becoming the sql server. The CMS will reside soley on the sql server and the content for the web site on the seb server(s). What I need to know is if it's possible to set up an active/passive node to accommadate this using the items mentioned above? From what I've been reading sql 2000 enterprise does clustering but I'm hoping this version of sql can be used for something. Any responses are appreciated.
We have (had) an active/active cluster. 2 physical machines, each running their own instance, clustered together. Node1/Ins1 and Node2/Ins2.
Node2 failed and Ins2 failed over to Node1 as it should. Node2 required that we rebuild the server (rebuild = reinstall O/S). Now we need to get Node2 back into the cluster and get Ins2 failed back over to Node2.
Does anyone know, for certain, the correct steps to accomplish this? Obviously, we could backup everything and completely destroy Ins2 and recreate it on Node2 then rejoin the cluster. But I'm looking for something less destructive.
Is it possible to reinstall SQL, then rejoin the cluster, and then fail Node2 over? Or will there be registry conflictions?
Any help would be appreciated. Also, if you have any links to some official documentation, that would be great too.
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 sql server 2005 standard edition with Active/Passive Cluster in production.
I have a new requirement where i need to create a new instance on this active/passive cluster that can be used by our sharepoint servers. Can somebody please let me know what are the steps that i need to follow like
1.What i need to ask my network admin? 2.How i need to proceed installing? I am planing to do this over the weekend where i have the liberty of some down time. Any help greatly appreciated Thanks
I have a 2 way cluster and I want to apply SP4 on it.
Basically, I have 2 servers. Server A runs a default instance and another instance. While the default services is disabled and the other instance is running, Server B runs the default instance and has the other instance disabled. This basically acts like a 2 way cluster (active/passive).
How can I apply SQL Server 2000 SP4 on the 2 servers and have all the nodes come up the correct way? What are the steps to achieve this?
I just tried to apply SQL 2005 Std SP2 on a cluster, and all succeeded except for the Database Services. I've looked about and can't see any specific information for this. The Summary.Txt is below. I thought I was following the appropriate steps, according to the SP2 Readme.
Thanks for any help. (I'm at the client today)

We have a SQL 2014 active passive cluster with 5 instances. When the cluster was installed one of the nodes was a virtual machine. As we started to have problems and this is not a Microsoft supported configuration we decided to replace the virtual node with a phyiscal one. On 3 of these 5 instances we configured static ports (1433 TCP) this was required for applications and firewall implementation.
Now with the physical node joined to the cluster we have issues with these three instances. Whenever one of these instances is moved to the passive node the server authentication is changed from mixed to windows only. I'm no SQL expert at all but to me it looks like the configuration of the instances are not replicated to the passive node? I found some similar problems on the net but these are mostly under sql 2008.
I have upgraded our test server and on non cluster production machine. My next server is a cluster and I don't have a test cluster server. Do I upgrade the active node and that is all or am I going to need to fail it over and upgrade the other node.
Also the prerequesite for the upgrade advisor is .net 2.0 I am going to up that on each server one at a time but I am only going to add the upgrade advisor to one node is that ok.
I read the SP1 documentation and it clearly states only patch the active node and do not patch the inactive nodes.
I need to install the SSIS components on the referenced database server. I believe the SSIS components are cluster aware, so I was planning on just doing add/remove and selecting the components. Rather than breaking the cluster apart to patch the components back to SP1, I was thinking of just running the SP2 install right over the top of the running cluster to bring everything up to SP2.
I'm looking for any suggestions/comments on whether this is the proper way to proceed or if I'm going to have a problem.
I want to host 2 seperate SQL databases and wanted to know if it would be possible to run this in an active active cluster config which each database running on a different server.
The clustering would be there in the event of failure of one of the servers but for normal operation the two sql instances would be completely seperate.
Is this configuration possible and would this give the best performance and resiliance from a 2 server setup.
Help, I have an active/active cluster with SQL2k5 Ent with SP2 installed on node1 that is currently running live apps, I need to add the 2nd node to have fail over functionality but if I use the Change Install from Add or Remove Programs on the primary node to add the 2nd node I get the following error.
"The File 'c:....SqlRun_SQL.ms' is not a valid installation package for the product Microsoft SQL Server 2005(SQL2K5VVS01). Try to find the installation package 'SqlRun_SQL.msi' in a folder from which you can install Microsoft SQL Server 2005(SQL2K5VVS01).
No I assume this is because node 1 has had service pack two applied. Does anyone have instructions how I can add node two without having to completely uninstall Node 1, as the doc€™s with SQL2005 SP2 say it can not be removed, a complete uninstall of 2005 must be done???
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.

I'm contemplating running two availability groups on a two node WSFC. The WSFC is setup with a file share witness (i.e. no shared storage). Can I safely run 1 AG on one primary node, and the other AG on the other node (as primary). Each AG would have replicas on the passive node. This would effectively allow both servers to be in use at the same time. In a failover event, I understand that both workloads would transfer to a single server - so the box needs to be sized appropriately.
We are in the process of building a 3 node SQL Server Cluster (Server 2012/ SQL Server 2012), and we have configured the quorum so that all 3 nodes have a vote (no file share witness as we already have an odd number of nodes).
As I understand it, this should allow the cluster to run as long as 2 of the nodes remain online.
However, the validation report states that 2 node failures would be acceptable and, when we tested this by powering off two of the nodes, the cluster did indeed continue to run on a single node.
I have installed SQL Server 2012 on Node1 successfully and trying add node on Node2 and its failing with below message. I attached the screen shot.
Here we are not doing multi-subnet failover clustering. Why we are getting extra and asking for IP and what IP should we enter there?Add Node option should automatically detect the IP we configured on Node1.
[Error Message] To support SQL Server multi-subnet failover clustering, you must select at least one valid IP address for every subnet in the cluster.
[Details] Microsoft.SqlServer.Configuration.Cluster.ClusterIPAddressPublicValidationException: To support SQL Server multi-subnet failover clustering, you must select at least one valid IP address for every subnet in the cluster.
What I have- Sql server 2012 (Standard Ed) Cluster on Windows 2012 R2 with both instances running on the same node- just to save on License, i.e. technically it’s Act/Pas cluster.
What I am looking for- how to configure cluster (e.g. via quorum, etc) to force both instances failed together? Means if for some reason 1-st instance will fail to node 2 another instance should follow (otherwise it will be Act/Act cluster and 2-nd license is required).
If there is no standard way (cluster configuration I mean) to do it I should create some custom process to monitor where each instance is running.
I am trying to install the MS SQL Server 2012 Failover Cluster on Windows Server 2012 . I successfully Installed the Failover cluster instance on my primary node.
But when I am running the installation process on passive node to add node in the failover cluster I am stuck with very unique kind of issue.
I am following the Standard process of Installation and I am getting the same windows for each next process, but after License Agreement window when I get the Cluster Node Configuration window, then in "SQL Server Instance Name" drop down box I am not getting the Name of Instance which is already installed on the primary node. But this Instance complete information is appearing in below given box.
Only issue is Instance name is not appearing in the drop down list, that's why I am not able to select and when I click on next it trough error and do not proceed.
(1) During installation of second node in active /passive mode do we have to assign new virtual sql sever name and IP address or can we join existing first node Virtual SQL server ?
(2) Do we have to carry full instllations in 2 nd node or only clint instllations ?what about location binary and data in 2 nd node ?
But I'm not sure if I have to install SQL Server first on node 2, then add it to the cluster. Or does adding it to the cluster also install the software?
