SQL 2012 :: Primary Server Went Down And Unable To Failover Services To Second Node
Mar 27, 2015
y'day we faced situation one of the primary server went down and unable to failover the services to second node . by checking in logs we found
Cluster network 'Public' is partitioned. Some attached failover cluster nodes cannot communicate with each other over the network. The failover cluster was not able to determine the location of the failure. 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.

I have not used log shipping before and find myself in a position where I need to reboot the secondary node and then the primary node and I don't actually need to failover.
Is there anything I need to be aware of. When rebooting the secondary node I assume the transactions will be held in the primary nodes log till the secondary comes back and just carry on once back up?
When rebooting the primary node nothing needs to be done and the log shipping will just start again once it has come back?

During the installation of the SSISDB in SQL 2012 AG, the password used to encrypt the database was not preserved. Now when the server is failed over, the SSISDB on the new primary node is not use-able.Document the password and decrypt after using the master key after failover.

I have a SP that runs on the primary in 18 min and 45 min on the secondary( poorly written cursor,trying to fix it).Both machines are Exactly the same.I ran them in the middle of the night when no one was on the Sec. Node as we use it for reporting.
PLE: 7,000+

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.

if for any reason AG fails over to async node, how replication behaves? As data will not be in sync with previous primary replica, how replication will work? I think that we have to reset replication from scratch as there's a high chance subscribers might be more updated than current primary replica as failover to this node causes data loss. How to keep replication in sync without resetting up? Can we achieve this?

I am running SQL 2014 2-node AlwaysON Availability groups, Enterprise Edition in our environment and 5 databases are part of AG.
Question is, sometimes AG is getting failed over to node2 but always our preferred node is node1 due to some business needs otherwise some of our jobs will fail.
So, what I looking for is, a sql script which can handle a situation wherein, for some reason, AG is failed over to node2, it should be able to detect if node1 is back online or not and if so, it should fail back to node1. How to do this using tsql query or stored proc or sql agent job ?

I'm contemplating running two availability groups on a two node WSFC. The WSFC is setup with a file share witness (i.e. no shared storage). Can I safely run 1 AG on one primary node, and the other AG on the other node (as primary). Each AG would have replicas on the passive node. This would effectively allow both servers to be in use at the same time. In a failover event, I understand that both workloads would transfer to a single server - so the box needs to be sized appropriately.

We are in the process of building a 3 node SQL Server Cluster (Server 2012/ SQL Server 2012), and we have configured the quorum so that all 3 nodes have a vote (no file share witness as we already have an odd number of nodes).
As I understand it, this should allow the cluster to run as long as 2 of the nodes remain online.
However, the validation report states that 2 node failures would be acceptable and, when we tested this by powering off two of the nodes, the cluster did indeed continue to run on a single node.

I have a 3 node 2014 AlwaysOn setup. The primary and secondary are set for automatic failover. The third node, of course, is manual (until 2016). The 2 nodes with are automatic are sitting in one datacenter, the third is in another. If the first datacenter was to go down, I would manually have to failover to the third node? What's the normal process here for having two datacenters and ensuring the availability group is always available?

Hello,
I wanted to instal sql server 2005 on our sql 2000 failover cluster.
The first thing i did was deinstal sql 2000.
The installation hangs on the dialog screen configuring components and does not present een error.
If i install the cluster with one node there's no problem.
But if i want to add the second node the installion hangs.
When i go to the second node and stop the scheduled task the installations stops.
Do you have any suggestion

I'm trying to do a SQL 2008 cluster installation.I installed one node and now I'm trying to add a failover cluster node.in the "add Node Rules" I get following message:
Rule Check Result...Rule "SQL Server Database Services feature state" failed.The SQL Server Database Services feature failed when it was initially installed. The feature must be removed before the current scenario can proceed.

I have a 2 node cluster with 2 standalone 2k14 instances having alwayson setup. As per client requirement we have created a client access point with a cname alias in dns to connect to secondary replica. Now, everytime whenerver the roles switch over one has to manually move this resource from the previous secondary node to the new secondary node. This is tedious, and should not be done manually either, so I am looking for a way to automate it so that as soon as the role switches over, the resource group after some time should also switch over to the current secondary.
Env details
xa (current primary)
y2a (secondary)
client access point (resource group): aglreadtest

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. Â 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

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

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.
Â
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 ?

When adding a node to a SQL Server 2012 Standard edition cluster, how I do I identify the location for SQL server shared components and the rest of the SQL Server installation binaries?
When adding a node to a SQL Server 2012 Standard edition cluster all the binaries went to the C: drive default location. We put those files on a different drive when installing the first node. What needs to be done so both nodes have the binaries on the same drives and folders?

I am creating simple report in ssrs and pass one parameter only. It will work perfectly (here user enter the parameter value). but i need that i should select the value in drop down box. i had tried many time and did different ways but I am unable to do it.
First i gave the parameter in my sql query in Data set (like WHERE COUNTRY = @COUNTRY) and i checked the Parameters tab in the data set. Here by default comes the Parameter Name: COUNTRY and Parameter value: [@COUNTRY].
Next i select COUNTRY Parameter in the Report Data Pane. and go to properties Here in General Tab: Name COUNTRY Prompt: COUNTRY, Select Get values from query in available values Tab (and also i tried with Select Get values from query in Default Value Tab) and Select Data set: Data Set1, Value field: COUNTRY and Label Field COUNTRY. And Click Ok
And tried to preview the report, it throwing below error
"An error Occured during local report processing. The definition of the report is invalid. The Report Parameter 'COUNTRY' has a DefaultValue or a ValidValue that depends on the report parameter "COUNTRY". Forward dependencies are not valid.
How can I achieve dropdown list.What i missed? Even i unable to do it Multi valued parameters and Cascading parameters.
Actually i am working on SQL Express 2012 version.

I have set up a 2 node availability group to take advantage of using the secondary node for a read-only replica. I actually am having two issues. The first being I can connect to the primary node using the listener dns name and ip address, but no longer can connect via its actual host name or ip address. I can ping the address with no problem, but I can't connect to port 1433 using the actual host name or ip address.
I am no problem connecting to the secondary node using its host name, but can not get to it through the listener using the applicationintent=readonly. Eventually I would like for everything to connect through the listener name, but for now still need to connect via the server's host name and don't understand why; everything I read is that the primary node should be able to be connected via both the host name and the listener name.

I'm sure there is a simple answer to this but it eludes me at the moment.
I€™m using the Developer Edition of SQL Server 2005.
The MSDB node under Integration Services->Stored Packages refuses to open.
It always fails with a login timeout message and that the connection was
actively refused.
I€™ve run the SQL Server Surface Area Configuration tool and allowed remote
and local access, even though it€™s all installed on the local machine. This
didn€™t help.
The next thing I did was to turn off all my firewalls and internet access
control software and it€™s still not working.
I€™m using integrated authentication and the user is part of the
administrators group,
any ideas how I can try and rectify this?
Thanks

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 read these instructions:
http://msdn2.microsoft.com/en-us/library/ms191545(SQL.90).aspx
But I'm not sure if I have to install SQL Server first on node 2, then add it to the cluster. Or does adding it to the cluster also install the software?
Thanks

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.

Test1:
Failover Server1 to Server2 --> Able to connect Listener
Failover Server2 to Server1--> Able to connect Listener.
Failover Server1 to Server3--> Able to connect Listener.
Failover Server3 to Server1 or 2 --> Unable to connect Listener. Unable to ping Listener.
Failover Server 1or2 to Server3--> Able to connect Listener.

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.
