SQL 2012 :: Add Node To Server Cluster

Oct 3, 2015

Can I add a new node to an existing sql server 2012 cluster witthout stopping all the current resources?

Currently, there are 2 nodes and 3 sql server instances, which can not be shutdown. Is the process of adding nodes a "online" process?

SQL 2012 :: Running 2 Distinct AGs On Each Node Of A Two Node Cluster?

Oct 23, 2014

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.

SQL 2012 :: 3 Node Cluster Runs With 2 Node Failures?

Jun 11, 2015

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.

SQL 2012 :: Specify Server Installation Location When Adding Second Node To Cluster

Jun 6, 2014

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?

Do I Need To Install SQL Server To Second Node In Cluster Prior To Adding The Node?

Jun 12, 2007

I read these instructions:

http://msdn2.microsoft.com/en-us/library/ms191545(SQL.90).aspx



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?



Thanks

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.

SQL 2012 :: Cluster With Multiple Instances On The Same Node?

Jul 14, 2015

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.

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 ?

SQL 2012 :: Node Cluster Active / Passive With 10 Instances

Jun 5, 2015

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.

SQL 2012 :: Instance Name Not Appearing In Drop Down List On Cluster Node Configuration Window

May 29, 2013

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.

Trying To Add A Node To A SQL Server Cluster

Jan 31, 2008

We have been working on a project to upgrade the servers in our 2-node SQL Server environment. I evicted a node after removing it from the instance. We added the new node under a new server name. I then start the Add remove programs, choose to change the SQL 2005 environment, type the virtual server name. Choose to maintain virtual server, pick to add new node. All seems well, I enter all prompted questions, and when the install begins I get the error below.

Product: Microsoft SQL Server 2005 -- Error 1706. An installation package for the product Microsoft SQL Server 2005 cannot be found. Try the installation again using a valid copy of the installation package 'SqlRun_SQL.msi'.

So I copied the SS2K5 Enteerprise Edition software to the local C: drive, point it too the 'SqlRun_SQL.msi' in the setup folder and still get the error.

Any one experience this or have any suggestions?

SQL 2012 :: MSDTC In Multi-node / Multi-instanced Cluster

Aug 17, 2015

More often than not, I typically don't touch DTC on clusters anymore; however on a project where the vendor states that it's required. So a couple things here.

1) Do you really need DTC per instance or one for all?
2) Should DTC be in its own resource group or within the instance's group?
2a) If in it's own resource group, how do you tie an instance to an outside resource group? tmMappingSet right?

How Do You Determine The Active Node Inside A Stored Proc For An Active/passive 2-node Cluster?

Jan 16, 2008

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.

SQL Server 2005 Standard On 2 Nodes Of A 4 Node Cluster

May 23, 2006

My question is, I'd like my actual cluster to have 4 servers. The virtual server that will be running SQL 2005 will only be installed on 2 of those nodes. Will this work or do I have to split my cluster in to 2 to meet the SQL Server 2005 2 node failover limitation? A basic config for the cluster would be like below....

ClusterSQLNode
Active SQL 2005 Server
ClusterExchNode
Active Exchange Server
ClusterAppNode
Active Application Server
ClusterFailoverNode
Failover SQL 2005
Failover Exchange
Failover Application

Will SQL 2005 install in a 4 server cluster if I only install it on to two of the nodes? Any potential gotchas?

DB Engine :: Defining MAX And MIN Server Memory Settings On 2 Node Cluster

Sep 29, 2015

On first Node A: The server has 16 GB of physical RAM. 
On second Node B: The server has 10 GB of physical RAM.

Now, this being Active Active, Node A can be clustered on failure onto Node B..Now reporting server is configured under these two nodes, with defined MAX and MIN server memory of 12 as MAX and 0 is min IN GB.Now with this setting on SQL whenever the cluster moves, such config make OS goes low on node for 10 GB.I am only left with option of switching this MAX and MIN to a default setting or is there any other alternative such as script which can change this setting accordingly when cluster moves to respective server.

SQL 2012 :: Log Shipping - Reboot Secondary Node And Then Primary Node

Apr 20, 2015

I have not used log shipping before and find myself in a position where I need to reboot the secondary node and then the primary node and I don't actually need to failover.

Is there anything I need to be aware of. When rebooting the secondary node I assume the transactions will be held in the primary nodes log till the secondary comes back and just carry on once back up?

When rebooting the primary node nothing needs to be done and the log shipping will just start again once it has come back?

Active/Active Cluster Failure - How Do You Rebuild And Rejoin A Node In The Cluster?

Aug 30, 2006

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.



Thanks

Remove DC From Cluster Node

Nov 9, 2006

We have:

A Microsoft cluster, (SQL Failover cluster) with one node as the domain controller. The cluster was built off site and the domain name used is the same as our existing domain where we eventually need to install this cluster.

We need: (At least I think we need:)

To remove node 2 from the "cluster domain", DCPROMO node 1 and eliminate the "cluster domain". We then need to join the cluster (nodes) to the existing domain. We also need to recreate the accounts and groups used during installation.

Questions:

1) What will happen to the "domain accounts" used when installing SQL2005? (Other than they will go away. I mean what adverse impact will that have on the installation?)

2) Will I have to re-install SQL 2005?

3) Is my paranoia real or imagined? (Will Elvis live?)

Any prior experience with this would be greatly appreciated. In fact, a WAG is appreciated too.



Regards,

Mike

Cluster Recovery From Node Failure

Jul 20, 2005

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.

Cannot Apply SP2 To 2 New Nodes In A 4 Node Cluster ?

Oct 12, 2007

HI There

We had an existing 2 node active / active cluster, 1 running a default instance of Sql Server 2005 Enterprise Edition 9.0.3152 (SP2 + Hotfixes) and the other running a named instance of the same version.

We recently added 2 new nodes to the cluster, they were successfully added and we tested the cluster group failover successfuly to the new nodes.

Last night we tried to install Sql Server 2005 Enterprise edition on the new nodes.

I followed to proper proceudure of modifying the installation for both instances and selecting the 2 new nodes to apply them to. This went 100%. Sql Server 2005 successfully installed for both instances on the 2 new nodes, all log files were successful.

We then tried to apply SP2, we tried the following:

1. We ran SP2 from the active node, but when we go to the screen to select what you want to apply SP2 too we could not select anything, if you clicked on database engine the message said that these instances were already at a later version and we could not proceed. This is how i successfully applied SP2 to the original 2 node cluster but it does not work for additional nodes to an exisitng cluster.

This is also what all the documentation we could find said, refer to SP2 release notes under the topic "Failover Cluster Installation", it is also the method we found when googling.

2. We then tried what is described under SP2 release notes "Rebuild a SQL Server 2005 SP2 Failover Cluster Node".
We ran SP2 from the new nodes while they were passive, but when we got the screen where you select what to apply the SP2 too we could not select database engine the message at the bottom said that SP2 must be run from the active node and that we were attempting it from the passive node, this is what we tried in step 1 described above.

3. This was a last resort. We were advised to try failing over the instance to the new node and then running SP2. Personally i thought this was a bad idea, one should never fail over a instance of sql server to a node with incompatible binary versions and secondly when we installed sql server on the new nodes a warnng popped up before hand stating that the instances were at a later version and that the new nodes must be at this version before attempting fail over. I thought that sql would not even start, to my surprie we successfully failed over the sql group to the new node, when we ran SP2 it looked good we could select the database engine on the new node to apply SP2 too, BUT after clicking next after a few seconds the SP2 installation just closed, NO INFORMAITONAL MESSAGES NO ERRORS NO WARNINGS it just closed an never came back.

I had never seen this happen on a cluster before, needless to say this made me very nervous so we failed the sql group back to the original nodes and gave up.

PLEASE can some tell me how to apply SP2 to 2 new nodes in a 4 node cluster all methods descibed in SP2 release notes and other documentation as descibed above in step 1 and 2 do not work !

Thank You

Identifying The Cluster Node By TSQL

Jan 18, 2008



Does anyone know of a way within T-SQL to identify the cluster node that the current SQL Server is runinng on?

We have a cluster of two SQL 2000 servers - one active and one passive. For some reason the two nodes are not identical and some code needs to run differently on each node. We need to do a check before running some code to find out what node the SQL instance is running on?

At present the only way we can find this out is through the cluster managemenr on the server.

Any help would be much appreciated!
