I am using SQL 2012 SE with clustering on Windows server 2008 R2. Now I want migrate it to windows server 2012 with minimal down time. So I want to evict the passive node and add a new node with windows server 2012 and install sql server 2012 SE on the new passive node and perform a failover(make the node with 2012 OS as active) and then evict the new passive node and add another node with windows 2012 and then do the same thing?
View 12 RepliesI 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...

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.

View 6 Replies View RelatedI'm getting the following error when I go to create a cluster in the Failover Cluster Manager in Windows Server 2008.
"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. There was a step that had me create a DNS A record for the address sql-cluster.contoso.com. The IP address was mapped to 10.10.10.111. I'm not sure if this is the culprit but its the only time I used that IP address in the setup.
Below are 2 screenshots. The first screenshot is the error. The second screenshot is my DNS console.
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.
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?
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.
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 ?

1.) Event ID: 1135
Cluster node 'XYZ' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.

The Cluster service failed to bring clustered service or application 'SQL Server (MSSQLSERVER)' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered service or application.
first of all,I went through all the logs, and could not find the reason for fail-over initialization. There should be some thing logged why the failover happened? secondly after failover the service was not coming online due to duplicate IP address detection.
Later when we try to manually bring the service online from cluster management it comes online successfully. I don't understand how would duplicate IP address get resolved when we start manually.
Lastly we see few errors related to physical disk resource between failover retries, is this could be the correlated to failover error ?
I have been facing following Error in Failover cluster setup as below. I have prepared 2 node and 2 instance sql server failover cluster on top of windows failover.I have deleted MTCBJINS07 in AD and recreated even after, problem is not solved. MTCBJINS07 is my 2nd sql instance sql server network name.
Cluster network name resource 'SQL Network Name (MTCBJINS07)' failed registration of one or more associated DNS name(s) for the following reason:
DNS bad key.Ensure that the network adapters associated with dependent IP address resources are configured with at least one accessible DNS server.
Curious on how this will work.. if i install sql 2005 standard edition on one virtual server.. to a fixed disk (actually 2 fixed disks.. one for C, one for D).. then install another 2005 standard edition on another virtual server.. do i just rerun the setup and suddenly the failover cluster option will NOT be greyed out?
Can anyone comment on this?
Thanks in advance.

I´ve been reading that SQL Server 2012 Always On is dependent on having a Windows Failover Cluster setup. Is that correct ?
View 6 Replies View Relatedcan 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 Server
4. windows Cluster
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 .
1<sup>st</sup> Method…
1. Open console command (Run->CMD with administrator privileges).
2. net stop winmgmt
3. Rename folder %windir%System32WbemRepository to other one, for backup purposes (for example _Repository).
4. net start winmgmt
2<sup>nd</sup> Method..
1. Disable and stop the WMI service.
a) Command : - sc config winmgmt start= disabled
b. Command : - net stop winmgmt
2. Run the following commands.
a). Command: Winmgmt /salvagerepository %windir%System32wbem
b). Command: Winmgmt /resetrepository %windir%System32wbem
3. Re-enable the WMI service
Command: sc config winmgmt start= auto
Last command to run after above steps
4. Command: mofcomp "%programfiles(x86)%Microsoft SQL Server100Sharedsqlmgmproviderxpsp2up.mof"
File not found Error for above command.
Can I build a cluster by adding the cluster service, then the SQL instances, then add the other nodes and their passive SQL instances?I would lean to building the cluster first, the add the SQL instances.
View 4 Replies View RelatedCould not able to connect secondary replica below is the error message I am getting when I tried to failover. Cannot connect to VLDBATEAM.
The secondary replica that you selected to become the new primary replica does not belong to the specified availability group. A possible explanation is that the replica has not been joined the availability group. (Microsoft.SqlServer.Management.HadrTasks)
I'd like to understand why it is not possible to automatic Failover Availability Groups using Failover Cluster Instances. I think it would be great for DR and HA. Do you understand why that limitation exists?
The link [URL] ....
SQL Server Failover Cluster Instances (FCIs) do not support automatic failover by availability groups, so any availability replica that is hosted by an FCI can only be configured for manual failover.
I tested the failover clustering for SQL 2008R2.When I stop the SQL server services manully, the failover did not fail to another resource. At the Faiolover cluster manager, SQl server(MSSQLSERVER) only show the status for offline. I think it should be move to another owner intead of just show as offline.

The cluster group fails over correctly but my data and log array's dont failover.
So I unplug the network cable from node 1 (active) the cluster group with the IP, name, and Quorum disk fails over to node 2 but the other groups sql data and sql log stay on node1 and dont failover.
Any ideas?

Hi all:
I was wondering what will happend to the transaction when the cluster failover from one node to another?
In my case the database is in node-001 and I need to restart the server on node-001. So I need to have the database failover to node-002, so I can work on node-001. During this process, will it effect to end-user?
Thanks

I have availability group with 3 node
2 in prod env and other one in DR
all replica configure with Asynchronous status
I would like to test fail-over first scenario prod env i would like to trying shutdown primary server and move to replica in prod.
I should move to replica prod from cluster service management or from SQL management studio
if i do it from cluster manager do you have power shell script for that
if i do it from SQL management studio i need the command
After manual AG fail-over from primary to secondary the application is not able to connect the listener name for atleast for 5 - 10 mins
The telnet fails during this time from app server, the listener ip is on muti-subnet.
At the same when i try to connect it from SSMS from a remote machine it works fine.
We need to start testing our Microsoft cluster servers.
Has anyone heard of any plan or products one can use to test
the failovers?
Please advise

We are running on SQL 2000 on Windows 2003. We have active-passiveclustering set up. We have 16 GB of RAM on each box. This pastweekend, we failed over. I noticed that the Total Server Memory wentfrom about 15.5 GB to 8 GB. I have been trying to figure out why thishas occurred. Any help would be greatly appreciated.

We need to install the webservice and the database on a failover cluster. Our plan was to install the web service on node 1 and the database would naturally be on the cluster aware sql service. We know the RS will not be cluster aware and if node1 bites the dust, reports will be out of business.
We were planning to do this tommorow on development, but then found this little tidbit - read the very last paragraph
http://www.microsoft.com/dynamics/crm/using/deploy/clusteringssrs.mspx
SQL Server Reporting Services failover cluster configurations that are not supported
Do not deploy both SQL Server Report Services and the reporting services databases on each node of a multi-node cluster. Moreover, do not deploy SQL Server Reporting Services in a two-node cluster environment that consists of an active node and a passive node where the passive node becomes active during a failover.
They don't explain why not to do it - as if it will destroy your machine! This is our main dev cluster and we don't need it to go down.
We will not be installing the RS on each node, just one. But I was thinking that if the dns entry for the service points to N1, it will continue to function and make successfull DB calls to the sql server cluster name.
Could this work? I've found posts of people installing RS on both nodes and having success - but this would probably require another license...which we don't have.
Thanks so much for your help - it is greatly appreciated.
