SQL Server 2012 :: Remove Named Instance From Failover Cluster
Oct 13, 2014
In QA we have a two-node cluster with four instances of sql. In trying to add a fifth, I was given an IP address already in use so the install hung.
I removed it from the cluster but it is still there in the registry etc on the node I was working on.
I read about using the maintenance tab of the sql server install to "remove a node" but the terminology is confusing. To me a node is a physical server and an instance is an instance of sql server -- not the same at all but they are often referred to as the same thing.
I definitely don't want to remove one of the servers from the cluster.
I am new to SQL Server 2012 clustering.I added a new instance to one of the two nodes.when I try to move it to the other node it fails.Do I need to install it on both?If so, what options do you install on the second node?
I have destroyed the cluster in failover cluster manager and then i am trying to remove node from the sql server installation centre.I am facing the cluster node and cluster service verification errors.I am not able to start the cluster service in services as well.
I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.
I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.
I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.
Should I be able to connect as serverinstances for a named clustered instance in 2012 ?
I've a fresh installation of SQL Server 2014 Enterprise on Windows Server 2012R2. I've setup de Windows Server Failover Cluster and the validation test has been successfully passed. I use mountpoint so I've disk M: that is the host drive for mounted volume m:Isql2014A that is the base folder for mounted volume
into these 5 mountpoint I've placed the SQL Server files.
After the installation of the first FCI I've re-run the cluster validation wizard and again it has passed successfully. When I try to failover the instance from one node to the other I have 2 problem:
1) every time I do failover, some disks fail to come online for a while and then succeed :
Cluster resource 'CLD - IstA - TempDB Data' of type 'Physical Disk' in clustered role 'SQL Server (ISQL2014A)' failed. The error code was '0xaa' ('The requested resource is in use.').
2) sometimes the SQL Server service fails to start, in the error log I see that the master database is not accessible. The master database in into the m:isql2014abinbackup.
I am trying to setup a client alias to connect to a named instance on another server.
TITLE: Connect to Server ------------------------------ Cannot connect to fred. ------------------------------
ADDITIONAL INFORMATION:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

------------------------------ BUTTONS: OK ------------------------------
I have set up the alias on the server and as expected it works. On the client side I have used the SQL Server Client Network Utility to configure the client side alias but no luck
I am using TCP/IP with a specific port ..
By the way the SQL is SQL Server 2012 Ent and the O/S is Windows 2012 R2 minshell
1. 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.
I have virtualbox installed on my notebook. For testing purpose, is it possible to setup SQL Server Fail-Over cluster using virtual box? I don't have a shared storage. How can I simulate that?
I am trying to create a failover cluster without the log shipping in 2012 as i've done it with a static instance with some database.Is the "AlwaysON" feature the solution when an application creates random and numerous databases within the instance and we need a failover scenario ?
I had a cluster running on 3 nodes (windows failover cluster) with server 2012 and SQL server 2012 running in the cluster. Well, I thought I'd just go ahead and rename all 3 of the hosts with new hostnames and it apparently broke the cluster pretty bad. Now when I open failover cluster manager I cannot see anything nor can I connect to the cluster object in AD. I re-named all of the hosts back to their original names but that didn't work.
We are implementing a multi-site (Windows Server Failover Cluster) WSFC to enable Always On between our primary and DR site. We are not going to use SQL clustered instances. We are not planning to use shared disks. Each node is running a standalone instance of SQL 2012.
I have successfully configured a 3 node multi-site Windows failover cluster with no shared storage. For quorum, I have defined a File Share Witness (FSW). The FSW has voting rights and is in the DR site. The setup looks like this –
WSFC –
•Node A – Site #1 (voting right = 1) •Node B – Site #1 (voting right = 1) •Node C – Site #2 (voting right = 0) •FSW – Site #2 (voting right = 1)
Again - There are no shared disks in our setup. We are not going to use SQL clustered instance. We are going to use Always On with these 3 nodes.
SQL Always On –
•Node A – Site #1 (Primary Replica) •Node B – Site #1 (Readable Secondary) •Node C – Site #2 (Readable Secondary)
All the setup including the “availability group” works properly under this setup. However, a failover to site #2 under DR situation is not working and I know why but don’t know what needs to be done to fix the problem.
The following works fine –
•Automatic failover between nodes A and B (same site – site #1) •Forced failover to node C in site #2 provided at least one of the nodes in site #1 is up (non – DR situation) - this will ensure the cluster is up
The following is not working –
•Forced failover to node C in site #3 when both nodes in site #1 are lost (true DR situation) – This is because the cluster is not up at this point.
I know I have to bring the cluster up somehow and I have not been able to do so by restarting the cluster service.
I tried to run the command to start cluster service.
Question –
How can I FORCE the cluster to come up in Site #2 on node C when it has no voting rights?
I have always worked with even number of nodes and shared disks with traditional clustering. I am not sure what needs to be done in this scenario with 3 nodes and a FSW.
How can we find the cluster failover count in always on ?
As my AG is configured as synchronous mode , AG went offline and we manually restarted the AG service when we check the properties on AG role they r in default setting ?
Prod - shared storage between server 1 and 2 Server1: clustered SQL instance with availability group as primary Server2: Passive server for clustered instance of PROD
DR - shared storage between server 1 and 2 Server1: Clustered SQL instance with availability group as replica Server2: Passive server for clustered instance of DR
Approach 2: Using replicated SAN Prod - Server 1: Standalone instance with availability group as Primary Server 2:Standalone instance with availability group as replica
DR - Server 1: Offline until Disk group 1 (Prod server 1) has been broken and brought online at DR Server 2: Offline until Disk group 2 (Prod server 2) has been broken and brought online at DR
Both these approaches will work wont they? I have only built and played with normal availability groups across servers, not mixing it with clustered instance replicated SAN
I am trying to install SQL Server 2012 onto an already configured and validated windows failover cluster (server 2012) but the process is hanging after installing the setup files.
The last entry in the log is:
running discovery on remote machine
and I've left it hanging like this for 4 hours and nothing happens.
would like to know if it's possible to install SQL Server Failover cluster instance with shared storage along with standalone installation with Always on ( always on uses WSFC underneath).
The box I am trying to connect to is running two instances of SQL Server. There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'. I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" /> However, I am having trouble connecting to the Default SQL Server 2005 instance. I have tried: <add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" /> but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used: <add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" /> but this doesn't work either.
Am I mssing something here? Any help much appreciated Thanks...
I've two instances(Default, Named[dynamicsFINANCE]) running on SQL server 2014. However, when I try to connect to named instance say (dynamicsFINANCE) using SQL authentication from local SSMS, I get below error message:
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
I assigned a static port number to the named instance [dynamicsFINANCE] 1450. I also setup the firewall rule to allow access to Port 1450.
I'm trying to configure a named instances of SQL Server 2012 SP2 to have specific IP addresses and listen to that IP on port 1433. Alongside this, I have the default instance running on a different IP and listening to that on port 1433.I've managed to get them configured so that they are reachable using the IP, and looking at the log for each they are listening correctly on that IP on port 1433; in addition, the default instance connects fine using the SERVERNAME.However, when I try and connect to the named instance using the SERVERNAME/INSTANCENAME syntax, I receive the following:-
"Cannot connect to SERVERINSTANCE. Instance failure. (System.Data)"
Configuration for the TCP/IP protocol for that instance is as follows:-
Protocol Tab
Enabled= Yes Keep Alive = 30000 Listen All = No
IP addresses Tab
IP1 Active = Yes Enabled = Yes IP Address = 10.1.1.1 TCP Dynamic Ports = 0 TCP Port = 1433
[code]...
The SQL Browser service is running and prior to switching off Listen To All, I could connect to the instance remotely using the instance name.
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 an active/active two-node QA cluster with four instances of sql. I need to add a fifth. In the past I always moved existing instances to the other node while installing a new instance.
Other than impacts to users from install reboots, is that a hard requirement?
QA is reluctant to have me put the four existing instances on one node for most of a day, fearing big performance slowdowns. Each node has 250GB of memory and each instance is allowed 50GB. Netapp disk backend.
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.
We have 2 nodes window Server 2012 R2 and SQL Server 2012 Enterprise Version cluster setup. We can switch roles and Node to one node to another and revert back to previous node with out any issues. But we are facing when one Node is restarted. We could not restart that Node in cluster Service start in Failover cluster Manager. Error Details is displayed as below inside double code."Cluster node NODE1 could not to join the cluster because it failed to communicate over the network with any other node in the cluster. Verify the network connectivity and configuration of any network firewalls."
I checked windows firewall. windows firewall is all of in Node1, Node2, SAN and DC.I have disabled and enabled the Internal and private network of Node 1. I have validated the cluster. it is showing no error though.
Node1: Public IP: 10.10.0.11 SubNet Mask:255.255.255.0 Default Getway: 10.10.0.1 Prefered DNS: 10.10.0.10 (Ip of DNS)
[code]....
Private Network: Not configured.pinging to each other ip is successful from one node to another.
We have sql server 2005 installed locally on 2 servers and want to set up failover clustering. Do we need to uninstall what we have then install as failover cluster? Thanks.
I have a production failover cluster running SQL Server 2000 at SP3that I want to upgrade to SP4. I do not have a test failover clusterto test with so I need the install on the primary server to work thefirst time. Per the information I have I just install the patch on theprimary server and it will install both on the primary and on thesecondary.However, I remember when I did the initial install and it failed. Thefirst problem traced to the fact that the install uses temporary filesunder the profile of the installing administrator and the id had neverlogged into the second server so the install failed on creating thetemporary file. The was a second problem that related to an OS featurethat had to be off for the install to work.If anyone out there has done this upgrade and remembers encountering aproblem and its fix/workaround I would appreciate a head up warning.Thank you-- Mark D Powell --
I have installed 2 node windows Fail-over clusters successfully. But QUARUM Configuration is not appearing in Failover cluster manager instead "Witness: Disk (Disk Cluster 4)". I have also configured quarum configuration from Quarum "Configure Cluster QUARUM Settings". I have attached the snapshots of windows cluster configuration. Is it the issue or not. I have not got any warning and error during cluster validation while installing Windows failover cluster. I am assuming it is okay and i can move ahead to installation of SQL Failover cluster setup.
Products used for installation in Virtual Machine: Windows Server 2012 R2 SQL Server 2012 R2 Note: Service Pack is not installed.
