Recovery :: Error When Setting Up Failover Cluster
Aug 26, 2015
I'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.

I'm getting an error adding Replica to SQL AlwaysOn failover cluster in the new availability group wizard. When I enter the name of the target node (secondary replica) server and press connect, I get the following:
A network-related or instance-specific error occurred while establishing a connection to SQL Server.
The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2) The system cannot fine the file specified
The SQL Browser service is up and running on the target. I am using an Azure VM for my SQL instance. This cluster spans geographies from our on-premise site to Azure via a VPN. This is a multi-subnet cluster. I'm attempting to create a new AG from the primary replica node and the target is a node on Azure called SSASNodeAz03.

1. In alwaysON fail over cluster, Once fail over to secondary replica, what will happen to connected session in primary node? can the session fail over to secondary seamlessly or need to re-login. what happen committed transactions which has not write to disk.
2. Assume I have always on cluster with three nodes, if primary fails, how second node make write/ read mode.
3. After fail over done to 2nd secondary node what mode in production(readonly or read write).
4. How to rollback to production primary ,will change data in secondary will get updated in primary.

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.

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?

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.
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 ?

Server : Windows server 2008
DB Server : SQL Server 2008 (SP1)
Here are the series of events which happened.
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.
2.) Event ID: 1049
Cluster IP address resource 'SQL IP Address 1 (XYZ)' cannot be brought online because a duplicate IP address '10.9.8.113' was detected on the network. Please ensure all IP addresses are unique.
3.) Event ID: 1069
Cluster resource 'SQL IP Address 1 (XYZ)' in clustered service or application 'SQL Server (MSSQLSERVER)' failed.
4.) Event ID: 1049
Cluster IP address resource 'Cluster IP Address' cannot be brought online because a duplicate IP address '10.9.8.112' was detected on the network. Please ensure all IP addresses are unique.
5.) Event ID: 1069
Cluster resource 'Cluster IP Address' in clustered service or application 'Cluster Group' failed.
6.) Event ID: 1066
Cluster disk resource 'Cluster Disk 25' indicates corruption for volume '?Volume{88552e6f-aea2-11df-9790-0026b92fffa7}'. Chkdsk is being run to repair problems. The disk will be unavailable until Chkdsk completes. Chkdsk output will be logged to file 'C:WindowsClusterReportsChkDsk_ResCluster Disk 25_Disk16Part1.log'. Chkdsk may also write information to the Application Event Log.
7.) Event ID : 1066
Cluster disk resource 'Cluster Disk 26' indicates corruption for volume '?Volume{88552e05-aea2-11df-9790-0026b92fffa7}'. Chkdsk is being run to repair problems. The disk will be unavailable until Chkdsk completes. Chkdsk
output will be logged to file 'C:WindowsClusterReportsChkDsk_ResCluster Disk 26_Disk4Part1.log'. Chkdsk may also write information to the Application Event Log.
8.) Event ID: 1049
(Same message as point 2)
9.) Event ID: 1069
(Same message as point 3)
10.) Event ID : 1049
(same message as point 4)
11.) Event ID :1069
(same message as point 5)
12.) Event ID :1205
The Cluster service failed to bring clustered service or application 'Cluster Group' 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.
13.) Event ID: 1069
Cluster resource 'Cluster Disk 17' in clustered service or application 'SQL Server (MSSQLSERVER)' failed.
14.) Event D : 1049
(same message as point 2)
15.) Event ID: 1069
Cluster resource 'SQL IP Address 1 (XYZ)' in clustered service or application 'SQL Server (MSSQLSERVER)' failed.
16.) Event ID : 1205
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 ?

We have set up Mirroring with a witness server and everything works fine when we failover from the SQL Management console.
However, if we failover when our Maccola client is connected, the client blows up - clearly because it can no longer connect to the database.
The ODBC DSN used by the Maccola client shows a checkbox for the 'select a failover server' but the checkbox is grayed out.
Also the summary of settings for the DSN at the end of the wizard reveals that the failover to server (y/N) option is set to N.
The default setting for this DSN is 'populate the remaining values by querying the server' but it doesn't appear to be getting the settings for failover from the server or any other interactive DSN settings either. The server is clearly set for mirroring.
Another suspicious item is that the DSN cannot connect to the server with SA permissions, even though the server is set to mixed security and we use the correct authentication.
Is it possible that the client MACHINE is not authenticating with the domain or sql server properly. We are logged into the client with the domain account that is the SQL admin account on the sql server box.
We should be able to interact with the sql server settings through the ODBC DSN on the client shoulnd't we?
Are we missing a service pack on the client?
Thanks,
Kimball

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.

Two node AO cluster setup.
I found errors frequently in cluster events at logs as below
"Cluster network interface 'Node1 - 10.X.XXX.1' for cluster node 'Node1' on network 'Cluster Network 1' failed. 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 adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges."
How to fix this issues? is it missing any patch OS or cluster side?

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.

Could 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.

Hi I just set up a new cluster and everything was working. Now when I try to test failovers like unplug the public network card etc...
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?
TIA

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 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

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.

Hi. Was hoping to get some advice on applying a hotfix to a SQL Server 2005 failover Cluster.
The hotfix I am applying (KB933508) relates to a Maintenance Plans issue with Server 2005 Service Pack 2. During installation I'm advised that unless the SQL Server and other services are stopped a reboot will be required, although I can still install the hotfix. However the installation is failing. There are error details in the relevant logs created in C:Program FilesMicrosoft SQL Server90Setup BootstrapLOGHotfix to the effect that the 'Debug' value in registry key 'SoftwarePoliciesMicrosoftWindowsInstaller' can't be read and that SQL Server was unable to add a user (the account under which SQL Server Agent and Analysis Services run) to a local group (the domain group in which SQL Server logins are contained).
Is this something simple like explicitly shutting down the services first before applying the hotfix or is there something else going on?
Regards,
YaHozna

Does any one know, any software out there that can provide a solid failover / cluster / high availability solution for SQL Server 2000 Databases.
I have tried Incepto but it requires an extra column in every single table that involves in Replication and its not gonna work
So Please advise.
