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 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.

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.
Hi all,I have recently changed IP addresses on my MS SQL cluster (the new IPaddresses belongs to a different network). Both physical node's IPaddresses and resource's IP addresses have been changed.Everything seems to work fine. The cluster is up and respondingnormally. The resources failover to another node when needed correctly.However, I have noticed that the time it takes for the resource tofailover to another node is much longer than in the past (before IPaddresses change). I have noticed that "Network Name" is the resourcetype that causes the delay. Could you please advise if there issomething that I overlooked and needs to be changed.updated as well, sothat groups fail over faster?Thanks,Aleu
View 5 Replies View RelatedIF you need to change the IP Address of a SQL Server Failover Cluster instance, here is the steps:
1. Open up Failover Cluster manager.
2. Expand the MS Cluster Instance that your SQL Cluster instance resides on.
3. Expand Services and applications.
4. Select the SQL Server Service.
5. In the main window pane (Middle Screen), you should see your SQL Server Cluster name, expand the plus to the left of it.
6. Under your SQL Server Cluster name, you should now see an 'IP address' section, right click on it and go to properties.
7. In the properties pane, you can change your IP address by entering a static IP.....or assigning a DHCP enabled IP.
I'm using SQL Manager from my Enterprise server to connect to my SQL Express server that will act as a witness to a db mirroring system. If I try to connect to the SQL Express server using its IP address, I get a "named pipes error 53." If I connect by browsing the network and connect to the Name of the Server "MachinenameSQLExpress", I am successful. I would like to be able to connect to the IP directly as it's not dependant upon certain services to be started or configured a certain way.
Thank you,

Hi,
I am trying to connect to SQL Server Express 2005 from a remote connection through the internet using an IP address in a string like this;
Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword;
the error I am getting is this
A connection was successfully established with the server, but then an error occurred during the login process. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)
anyone have any suggestions or maybe another way to achieve this type of connection?
Thanks,

Hi All
This is a Pearler !!. SQL 7 and NT 4
Site A and B are 30 miles apart
"Site A" SQL 7.0 Cluster with Drives on Shared Storage.
"Site B" SQL Server Cluster with Drives on Shared Storage
Both Configured as Active/Active (8+ databases <100GB total)
How can I get the DB's (all) from Site A and allow a DIFFERNET cluster to control them.
Basically, I want to move all DB's from "Site A" and bring them into "Site B" with all relevant data ..ie master DB etc . I have a time window of 90 Mins and I cannot lose one single piece of data.........( I need to lie down now)
Help would be apprecitated)
We have an HA configuration with an Active-Passive Cluster / Shared Disk SAN which is working great. I have been looking for how to replicate the information to our DR site. We have many databases (some are more static vs. other transactional). I had some questions:Would it make sense to configure a snapshot for the static databases? 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? Is it possible from a clustered primary?Is log shipping too archaic?
View 4 Replies View RelatedDear all,
I wasn't able to connect to my SQL server 2000 database (which reside in the network in a windows 2003 server) after the IP address of the server has changed and the server is shut down, moved and re-started.
I was able to connect to this server by using ADO using VB. I was able to register this server in my EM and was able to create ODBC connection. Just when using ADO.NET, I wasn't able to connect. Any ideas? Will there be any caching within ADO.NET still pointing to the old IP address?
Thank you for all the help in advance.
Hi, I am connecting from clientside with sql server 2005 installed trying to connect to a database running on a server with sql server 2000 installed. this is not a 2000 to 2005 compatibility issue.
I can connect locally fine to the server and log in using the sa account, however for BDE admin i HAVE to use the server name instead of ip address. If i try to use the ip address of the server, the connection dosnt get established. *this is all happening localy on our own network.
How to I use ip address to connect instead of the server name? I will need to connect remotely outside of our network later on, and i dont think I can use the servername. Does anyone have a solution? thanks.
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.
View 1 Replies View RelatedI 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?
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?
I am trying to cluster two sql node server on hyper-v both virtual and my situation is below :
two hyper-v host connected to vnxe storage
two hyper-v are mapped to 3 LUN ( SQL Data , SQL logs , Quorurm)

three LUN are mapped to the virtual SQL01 and SQL02 as VHDX and configure it on virtual machine as IDE below is the picture
LUNs are presented to the guest SQL01 and SQL02 and visible through disk management
When create the fail over cluster i am not getting the disk to add them to cluster
Getting the below error when validate the storage :
No Disks suitable for cluster disks were found, For diagnostic information about disks available run the Validate config wizard’..
Also , regarding this LUN how i can make them shared on the host side ?
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?

"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.

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...

does anyone know of any potential issues of using a 32 bit sql server 2005 instance used for disaster recovery of a 64 bit sql 2005 cluster ?
thanks
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?
My environment has a 4 node cluster , 2 in primary and 2 in sec dc. Storage is sperate for both.
Need to setup always on for 4 Instances there on the 2 nodes of the primary dc. Is there any restriction in setting up always on for multiple instances for a cluster.
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: A connection timeout has occurred on a previously established connection to availability replica 'FIN-IE-PA078' with id [6910F4A9-87E7-4836-BA79-0F41BE90266D]. Either a networking or a firewall issue exists or the availability replica has transitioned to the resolving role.
05/08/2015 11:18:06: 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.
Is it possible to have more than one instance of SQL Server on a failover Active/Passive cluster? What are the concerns/ramifications if that indeed is possible?

I am having trouble to use SSMSE to remotely connect SQL Express server using IPs other than the base IP of the machine.
Machine settings:
(1) Has multiple IP configured. Those IP are accessible remotely
(2) Firewall is not on.
SQL Express server configuration:
(1) TCP/IP and named pipe are on
Browser service state:
(1) running
(2) listening at 0.0.0.0:1434 (UDP)
SSMSE connection results:
(1) with <baseIP><instance>, connects OK
(2) with <otherIP><instance>, connection failed.
Both connections use exactly the same authentication information.
Testing results using telnet:
(1) telnet <baseIP> 1434, OK
(2) telnet <otherIP> 1434, OK
Does SSMSE actually only listen on the base IP even it shows to listen on all the IPs?
I am having Windows 2012R2 Std with SQL2012SP2. Trying to add SQL cluster node2 but unable to locate the instance name when I click on drop down button.Understand that SQL Server Agent is required but it is not listed as cluster resource. Therefore, I perform the followingFrom Windows Power Shell with Administrator rights
1. Import-Module FailoverClusters
2. Add-ClusterResourceType "SQL Server Agent" c:windowssystem32SQAGTRES.DLL
Error: Add-ClusterResourceType : Unable to locate the cluster service executable on node1.The network name cannot be found.No problem to ping all cluster related names as well as fail-over to and from next available node.
I have a 3-nodes AlwaysOn cluster (Windows Server 2008 R2 SP1 + SQL Server 2012 RTM), Node Majority quorum, the quorum vote for each node is 1.
Today the AlwaysOn AG was suddenly down due to the cluster service on node 1 stopped and can't be started.
The error in eventlog is -
The cluster database could not be loaded. The file may be missing or corrupt. Automatic repair might be attempted.
The Cluster Service service terminated unexpectedly. It has done this 2 time(s). The following corrective action will be taken in 120000 milliseconds: Restart the service.
The failover cluster database could not be unloaded. If restarting the cluster service does not fix the problem, please restart the machine.
The Cluster Service service terminated with service-specific error The system cannot find the file specified..
The error log in cluster log is -

Now the cluster service can't be started on node 1, error code 2. Looks like the clusdb in C:windowscluster is missing or corrupted. How to restore the clusdb file? And how to prevent this happen again?
All nodes were well patched, AlwaysOn and cluster related hotfixes were all installed. [URL] .... doesn't wok.
In case of hardware unrecoverable issue, I have two msdn articles which states different things.
First one claims you remove the node from mscs.
[URL]
Second one claims you should remove it using sql server installation and links to the first link which says you should do it from mscs:
[URL]
Then this third article invalidates the second article. "To remove a node from an existing SQL Server failover cluster, you must run SQL Server Setup on the node that is to be removed from the SQL Server failover cluster instance."
[URL]
It is a hardware faillure where the secondary node is inaccessible.
So what is the proper way to evict a node you cannot access due to a hardware failure?
note: I don't plan on adding back the failed nodes after removing it. i.e. I am interested in the removing part.
