SQL 2012 :: Server Cluster Without Windows Failover Cluster

Feb 18, 2014

I´ve been reading that SQL Server 2012 Always On is dependent on having a Windows Failover Cluster setup. Is that correct ?

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.

Failover Cluster Using 64 Bit Windows 2k3 On Single HBAs And DS400 With Dual Controller

Apr 12, 2006

We are trying to setup a system to system failover cluster using twonodes (x346) which each have a single hba running to seperatecontrollers on the DS400.For full redundnancy, IBM recommends dual path from each node but wedont need that. The current setup has two completly seperate paths. hbaon node 1 to controller A on DS400 and hba on node 2 to controller B.If i take a controller offline, failover works fine to jumo to othercontroller and throw all resources to it's node but if i shutdown anode- the cluster loses all attached storage and DS400 is unaware toswitch ownership to other controller.Is there a way to us mscs without dual path from each node?anotherwords... if either node or controller fails on a single path, wewant the other path to become active.our main goal is to use sql server 2005 clustering on the cluster.everything checks out perfect if i only use one controller on the DS400for both nodes but this brings us back to another single point offailure.I saw that Qlogic has MPIO drivers on thir website for the DS400 but itseems as though they are for 32bit systems and the install errors outwith:C:Driversmpio1.0.8.4 (w32)>install.exe -iPre-Installing the Multi-Path Adapter Filter...SuccessInstalling the Multi-Path Bus Driver...Failure.

SQL 2012 :: Renamed Failover Nodes For Cluster And Broke It

Apr 17, 2014

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.

SQL 2012 :: Multi-Site AlwaysOn Failover Cluster

Oct 6, 2014

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.

SQL 2012 :: VMWare Snapshot Breaks Windows Cluster?

Dec 17, 2013

We have set up SQL server 2012 alwaysOn availability group on windows 2012. It runs and fails over successfully. Recently, a VMWare creates a snapshort of a primary and it breaks a cluster. We saw errors in a cluster log.

In VMware setting, The quiesce option is turned off for these VMs. Also, we configured cluster setting :Windowssystem32> (get-cluster).SamesubnetThreshold = 10 ( Relaxed )

Cluster node 'Test1' 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

File share witness resource 'File Share Witness' failed to arbitrate for the file share 'TestTEstQuorum'. ensure that file share 'TestTestQuorum' exists and is accessible by the cluster.In alwaysOn error log, A connection timeout has occurred on a previously established connection to availability replica 'Test1' with id [CAD40D99-E333-457E-9993-BBE977D2CDA2]. Either a networking or a firewall issue exists or the availability replica has transitioned to the resolving role.

Upgrade SQL Server 2000 Failover Cluster From SP3 To SP4

Sep 13, 2006

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 --

DSNLess Connection With Failover On SQL Server 2005 Cluster ?

Nov 20, 2006

Hi,

We have configured two SQL Server 2005 in a cluster (without Witness).

We have severals ASP (using ADO) that are connecting to SQL Server 2005 with SQL Native Client in a DSNLess connection String :

driver={SQL Native Client}; server=MAINMAIN; Failover Partner=BCKUPBCKUP; uid=log;pwd=pwd;database=MyBase

When using this connection string, the connection to MAIN is alrigth, but when we simulate a unavailability situation on "MyBase" or on the entire MAIN instance, the new connection are joining the MAIN and not the BCKUP SQL Server.

We tryed several Connection Strings including Failover_Partner, Initliag Catalog instead of database... but no one succed in joining the BCKUP SQL Server.

I precise that the DNS on the PC that connect to SQL server is configured and both MAIN and BCKUP are resolved in command line or in explorer.

Is there an other driver that must be used, or is there an other parameter to set in the connection string ?

Regards.

Sql Server 2005 SP2 Unattended Install For Failover Cluster

Jan 17, 2008



Hello All, I am trying the following script to upgrade SQL Server 2005 SP1 to SP2. I have an Active Passive cluster configuration. I have default instances of SQL Server. I am using the following script.

start /wait c:1sqlserversp2SQLSERVER2005SP2-KB921896-x86-ENU.exe /allinstances /quiet.

The sql server install fails to run. When I used the above command with just

start /wait c:1sqlserversp2SQLSERVER2005SP2-KB921896-x86-ENU.exe /quiet still the summary.txt file came with authentication success and that is all. I changed the above script and did

start /wait c:1sqlserversp2SQLSERVER2005SP2-KB921896-x86-ENU.exe /instancename=instancename of the cluster

This worked, however the install patched the passive node (DB engine, all the cluster unaware components) but failed to patch the DB engine on the Active node. I had to run the SQL Server sp2 install manually but still it did not patch the DB engine on the primary node

1. Can someone please help me with this issue as I want the unattended install to work. so it installs both active and passive node. I will post the final output and also the ADS script to do this as a bonus if this works.

Here is the summary.txt file.

SQL Server 2008 :: Change IP Address Of Failover Cluster Instances

Mar 9, 2011

IF 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.

SQL Server 2008 :: Installing Reporting Services On Failover Cluster

Jun 16, 2015

if it is supported to install Reporting Services on both the active and passive nodes in an SQL Server Failover Cluster and use the non-active node as a warm standby?We have relatively simple reporting requirements so the idea would be that if Node 1 went down, we could just repoint our users are Node 2 temporarily. Both reporting services instances would be configured to target the same SSRS database running on the SQL Cluster.
