Windows 2008 R2 Failover

We have a 2 node Failover cluster created in a Node and Disk Majority (recommended) condition. The nodes have shared Quorum and Data Disks on iSCSI SAN.   The only application on these nodes is SQL Server.   When
we tested the failover by moving the application, we found that the Quorum disk did not failover and the services did not start automatically.    My readings on Windows 2008 R2 failover suggests that the first situation with the Quorum is normal
but I don't know about the services.   Can anyone assist?   This is our first go at Failover.
SQL Server is one of a very few application you'd better install using own clustering features instead of a generic failover clustering. See:

How to install a database on a MS Windows 2008 R2 failover cluster?

Hello,
I have to install a Oracle 11g R2 database onto a MS cluster (Windows Server 2008 R2 Failover Cluster with 2 nodes and shared storage). I installed the DBMS on both nodes. On the first node, I created a tablespace, the files are on the shared storage. I can connect to that database, up to here everything is fine.
But the problem is: How do I have to configure the DBMS on the second node to use the existing database files in the case when the second node gets the Cluster IP and the shared storage? The switchover is done, all database files (in the filesystem) can be seen on the second node.
The goal is to connect to the database from an external application, regardless which node is active.
I know the "Oracle Fail Safe Manager", it is already installed on both nodes.
A link to the related documentation would be helpful, I can't find anything.
Best regards,
C. Jost

Hello,
But the problem is: How do I have to configure the DBMS on the second node to use the existing database files in the case when the second node gets the >Cluster IP and the shared storage? The switchover is done, all database files (in the filesystem) can be seen on the second node.When you switch the database from one node to another one do you have any error ?
Can you connect to the database and check for the Tablespaces ?
Normally, with OFS you define Groups. In one Group you'll have the Database, the Disk, the IP address and the Listener. So when you move the Group from one node to another one, the disk will be recognized on the second node then, the database, listener, ... will start and, there's no reason to loose a datafile.
Please, find enclosed, an introduction to Oracle Fail Safe concept:

How to test node failover in Windows 2008 R2 Failover Cluster?

Can anyone give me advice on how to properly test a node failure with a 2 mode Failover Cluster in Windows 2008 R2?

To test the failover of a clustered service or application
In the Failover Cluster Manager snap-in, if the cluster that you want to configure is not displayed, in the console tree, right-click
Failover Cluster Manager, click Manage a Cluster, and then select or specify the cluster that you want.
If the console tree is collapsed, expand the tree under the cluster that you want to configure.
Expand Services and Applications, and then click the service or application for which you want to test failover.
Under Actions (on the right), click Move this service or application to another node.
As the service or application moves, the status is displayed in the results pane (center pane).
Optionally, repeat step 4 to move the service or application to an additional node or back to the original node.

The acount information could not be verified - SQL 2005 SP3 installation on Windows 2008 R2 Failover Cluster

Hi,
We have a problem when we are trying to install SQL SP3 on SQL 2005 cluster.
The problem is described bellow:
We installed a new Windows 2008 R2 x64 failover cluster with two nodes.
As a next step we installed SQL 2005 Enterprise edition x64 on this failover cluster. We have finished the installation without problems. After SQL installation we are trying to install SQL SP3 . We have logged on using a domain administrator account and
we start the installation of SP3 with that user. In authentication mode screen the test gives a success status using either domain administrator-windows authentication or sa-sql authentication. On remote user account screen, when we give the domain
administrator account we get the message "the account information could not be verified. Press ok to return to authentication mode screen to determine the reason for failure".
We have tried to give the SQL services startup user on remote user account screen but the error is the same.
the domain administrator account exists on security logins of SQL with sysadmin rights.
Can someone help?
Thanks.

Hi StelioMavro,
According to your error message, when you install SQL Server 2005 SP3 in your failover cluster, we need to verify if there was other instance that had been removed and the installation did not pass the login check. I recommend you use windows authentication
instead of SQL Server authentication when applying SP3. And the windows account used to run the SP3 setup program must have administrator privileges on the computer where SP3 will be installed.
For more information about how to install SQL Server 2005 SP3 in failover cluster, you can review the following article.

How to install DB6(DB2 for LUW) on a windows 2008 R2 failover cluster NodeB

Hi Gurus,
I am building a ECC6 EhP4 cluster on windows 2008 R2, I am following the installation guide chapter 7(document name: Installation guide SAP ERP6.0 EhP4 Ready SR1 ABAP on windows: IBM DB2 for Linux, Unix and Windows). But the step listed in the guide are not so clear and I have trouble for the database installation on the second node.
What I have done is:
1. 7.4.1 Preparing the database for MSCS step1 and 3
2. 7.4.2 Windows Server 2008: Creating the sap services and application
3. 7.4.3 Installing the central services Instance for ABAP (ASCS)
4. 7.4.4 Configuring the first MSCS node
5. 7.4.5 Installing the database instance on an mscs node(as i have done 7.4.1, i got some error in this step, then i checked some note and in note 1493410, it mentioned don't do step 7.4.1, so I uninstall the DB2, and get this step finished)
6. 7.4.6 Configuring the database for MSCS
7. 7.4.7 Configuring the Additional MSCS Node
8. 7.4.8 Installing an Enqueue Replicaiton Sever
9. 7.4.9 Installing the central instance
10. 7.4.10 Installing the dialog instance
Now I got problem on the database group, I cannot fail this to the second node. the DB2 Server resource cannot bring online to the second node. I think step 1, 4 and 5 may has some issue, but I don't know how should I install this database.
note 1493410's word confusing me, below is part of that note:
Chapter "Preparing the Database for MSCS"
You must not apply this chapter at the beginning of the installation. Instead, start the installation process with the next chapter "Configuring the First MSCS Node"
Follow the instructions in chapter "Preparing the Database for MSCS" in the exit step described in the chapter "Installing the Database Instance on an MSCS Node" before executing the db2mscs tool on the additional MSCS node only.
Point "3. Install all required operating system users ..." of this chapter is obsolete.
Anyone think my cluster still have chance to be fixed or I need rebuild it from scratch again. If I need build it again, I still don't know how to do the database installation on the second node
BR,
Peter

Hi pal,
Have you identified Ips and group names on which your sap application and DB should run..
I will give a overview...
Exam ples -
NODE A                  - 192.168.x.1
NODE B                   - 192.168.x.2 are the one which you idetify physical systems
1) Identify the drives you want to map for application and DB and make a partation and name the drives
2) Initially create Microsoft cluster service which creats cluster group----
CLUSTER GROUP   - 192.168.x.3 - Cluster name could be any thing meaningful...
Quorum disk          - 192.168.x.4 - 1 Gb drive
In point 2 if you are creating Cluster service with Heart ips you will naother ips for NODE A and NODE B ( 10.0.0.1 and 10.0.0.2)
3) Test and validate cluster configuration and ensure no erros are reflected
Above activities can be done with the help of OS Admin....
Now start working with SAP installation, even before that identify 2 names and ip address for SAP installation
Application group name can be as follows --
APPLPRD - 192.168.-x..5
Database group name can be as follows -
DBPRD - 192.168.x.6
You when you identify above drives for file systems and groups , you can start installation as mentioned in th guide...
Also let us know if you atrying to install EHP4 or EHP4.. as there some corrections to be followed in EHP4..
Open a new thread if you facing futher issues...
thanks,

Windows 2008 R2 Failover Cluster - Netapp FAS6280 Black Screen on Restart when in cluster IGROUP

Hello everyone,
I've been working on this issue for a month now and have tickets open with Netapp and Microsoft. We have not been able to resolve the issue as of yet and since I'm losing all my hair I thought I should post it...
Scenario:
Two Windows 2008 R2 Enterprise SP Fail-Over Clusters (C1 & C2)
Two Netapp FAS6280 Filers for SAN storage
8 DELL R815 servers w/ 2x QLE2562 8GB FC HBAs all paths used (9.1.9.47 - newer did not resolve)
Netapp DSM 4.0 & SnapManager 6.4.2 (we also tried 1 rev newer, 1 rev older without luck)
C1 has 2 nodes & C2 has 4 nodes.
We are trying to add new nodes into the clusters. We were originally on EMC Clariion arrays and have been migrated to the netapp. Prior to moving we had 3 nodes in C2 and added node 4.
Now we want to add 2 more nodes, one to each cluster. We were able to configure the OS and get everything installed and matching the other nodes. we can assign HBAs to a test IGROUP and assign a lun, format it use it restart all is well and normal.
As soon as we change the HBAs to the IGROUP for C1 or C2's LUNs the servers don't want to restart properly. They hang at a black screen. The little green windows start splash screen runs the bar at the bottom. it then is supposed to fade
out and come back with the grey screen saying starting windows but that doesn't always happen. Sometimes it can take 4 hours to restart, or the machine will not come back onine at all. The pre-existing nodes *do not* experience this issue.
They restart in 5-10 minutes without issue.
We know drivers are part of the issue, but the maddening part is that it all works fine until we try to add the HBAs to the existing cluster storage group. We have a suggestion to create separate IGROUPs for each cluster node and add all luns to the
separate igroups. We configured this on one node and it still restarts long. We plan to modify the other nodes during our maintenance window and try again.
On the other cluster we were able to successfully complete the validate wizard and join. everything fails over and works except the server does not come up upon restart. If I unplug the HBAs it will come up fine, then I can plug them in and the
cluster functions.
Does anyone have any other ideas for us to try? Currently support for both netapp and Microsoft appear stumped. Sunday is our Window and we plan to try reconfiguring but I'm losing optimism...
Thanks for any feedback/ideas!
-Ryan

Thanks everyone who looked at this and offered feedback.
The issue appears to be resolved after the configuration change suggested by Netapp support.
The originally recommended configuration for our storage migration was similar to how I've seen storage groups configured on EMC arrays in the past. 1 storage group / igroup with all hbas/initiators for each host in the WFC/SQL cluster added to this
group. that group then gets all LUNs assigned to it.
The change in configuration that was recommended is to have 1 storage group / igroup for each host and put all initiators/hbas for each host in their own separate group. Then assign the all LUNs to each of the individual host igroups.
There is a lack of documentation on this, but it appears to work. We had 1 hit for separate igroups but had to go through a couple of support techs to get one to confirm this.
After applying this configuration in our change window today the issue is resolved. we were able to fail all resources onto the new node and restart it without issue. The question remaining for us is why the old systems continued to work while
the new nodes did not. The old nodes were originally migrated off an EMC and the version of ONTapp at that time was 8.1.2 and they worked fine.
We had upgraded to 8.1.3 to resolve an issue with flash cache and it seems like machines that we tried to attach to this igroup after that time did not work. all drivers software etc the same. We are wondering if this is somehow related and have
asked about it.
I wanted to update this thread, and perhaps it can save someone else some trouble down the line.

Windows 2008 R2 Failover Clustering Issue - The operation returned because the timeout period expired.

I am trying to get a new Windows 2008 R2 cluster to work on two VMware servers (VMware ESXi 5.0.3) and am experiencing some form of timeout issue during the creation of the cluster according to the logs.
All validation checks pass successfully, whether trying to create a single node or dual node cluster, but the same error message is seen when creating the cluster. I have tried various suggestions found but none of them have made a difference. In an effort
to further diagnose the issue I enabled the following diagnostic logs:
- FailoverClustering
- FailoverClustering-Manager
- FailoverClustering-Client
The only useful error I can find is in the FailoverClustering-Client log which reports an error 'Couldn't resolve tcp binding to cluster' for each physical node to be part of the cluster.
In order to further diagnose the cause of the issue, I am looking for any options for increasing logging when attempting to create the cluster. Is there a way to increase the logging to see what the actual timeout is occurring with?
Alex.

Sorry, I should have been more clear ...The servers I am attempting to create a cluster with are Virtual Servers running on a VMware ESXi (5.0.3). They have access to two shared disks (connected to each VM using a separate SCSI Controller from that for the
disk used to install the OS) with Virtual SCSI Bus Sharing set within VMware.
Each Virtual Server has two NICs configured (with static IPs) - one for internal (domain connectivity) and the other for heartbeat connectivity. The servers can ping each other via both interfaces, as expected, but only domain connectivity works via the
internal NIC.
I have tried creating a single node or dual node cluster and get the same error each time. When the cluster is attempting to be created I can see the new computer object is created in Active Directory (which is then deleted when the cluster creation fails)
and I have also tried pre-creating the computer object and specifically setting permissions on it.
When creating the cluster I have tried via the GUI and via PowerShell (both with and without the option to attach the shared storage) but always get the same type of timeout error message. I am hoping there are further debugging options that can be used
to provide a better output as to what the timeout is occurring with.

Microsoft update KB 3002657 and 2008 R2 failover cluster for virtualization

After installing Microsoft update KB 3002657 on my Windows 2008 R2 failover cluster for virtualization, nodes in cluster lost connection to CSV and all my VM's were moved to node owning the volume.
I lost whole day to solve that problem.
But should i keep that update not installed on cluster nodes or anyone maybe has a solution for that ?

Hi a3pl,
Unfortunately, the available information is not enough to have a clear view of the occurred behavior from the cluster perspective. Please offer us
more information such as the failover cluster validation error, the failover error event ID, with the current information it is difficult to presume which part may cause this issue, we strongly suggest you install the following update when you use failover
cluster.

Windows 2008 Failover Cluster - Cannot add a generic service

Trying to add a generic service in a failover cluster.
Select the option Services and Application and it opens the wizard and then displays the error "An error was encountered while loading the list of services. QueryServiceConfig failed. The system cannot find the file specified"
The cluster validation wizard completes successfully. Permissions do not appear to be an issue as this account can seemly do everything else so I am at a loss to understand why this API is failing when it tries to query the server for services information.
Having searched the Internet the only thing I have found was someone posting a similar issue in the Greek language Technet forum(if I recall correctly) and their comment was they rebuild their cluster.
Windows 2008 (SP2) x64 two node cluster running a non-Microsoft database. We need to add a non-Microsoft Enterpirse backup solution and this is their documented method (adding it as a generic service) - both bits of software are from big vendors.
Symantec AV, but have tried with that disabled so don't think it has anything to do with that. Something is stopping the API from reporting back but I can't find what.
Really appreciate some help before we have to log a chargable call with Microsoft support
Thank you

Windows 2008 failover clustering fails with Event ID 1205 1069 1558

I have a two nodes Windows 2008 and SQL 2008 cluster running in active\passive. I was restarting
my nodes after applying windows update then I received the following error message below within Failover Cluster Manager. I get errors with Event ID 1205 1069 1558 this happens every month .. Could someone help me on to find the root cause for
this issue how to check if it is an issue with network or Quorum drive ?

First, take a look at the 1069 event. This should point out which resource is failing.
Then, open a command prompt and run the command: cluster log /g
This will generate a cluster.log file that you can use to further troubleshoot this issue. The log file will be located in the C:\Windows\Cluster\Reports folder.
The cluster.log will be based on GMT time, so you may need to translate this to the local time zone in order to find the events you are looking for. Look for ERR or WARN messages and these should hopefully give you more insight as to why the resource is
failing.
Hope this helps.

Which account is used to failover to passive node of Windows 2008 R2 2-node cluster?

When I set up drive letter for shared drives in Windows 2008 R2 2-node cluster, I accidentally used a drive letter which has already mapped automatically due to the login I used.   After I run the cluster validation tests, all the drive letters
for shared drives are changed.   I fixed this issue by disconnecting the automatic mapped drive and reassigned all the drive letters.
However, I wonder whether CNO is used to perform the failover so such issue will not occur actually. Also, what happen if someone is logged on the passive node when the failover occur and any of the drive letters assigned for the shared drives
is already mapped due to that person's login.

Hi Sebastian,
Let me clarify my question. For example, there are clustered drives W:, M:, and L:.   Active Directory Group Policy has policy for some users to have mapped drive M:.
What will happen if failover occurs when one of the users having that policy is still logged on the passive node?
What will happen if failover occurs but that user has already logged off the passive node?
AKAIK, mapped drives are tied to the current logon user not for all users.
I don't know which account is actually used for the failover process. CNO, VNO, the domain user account used to create the windows cluster, or ?
Thanks.

Can't remove Failover Cluster feature on Windows 2008 R2

Hello
When remove the Failover Cluster feature has following message:
Cannot remove Failover Clusting
This server is an active node in a failover cluster. Uninstalling the Failover CVlustering feature on thos node may impact the availabilty of clustered service and applications. It is recommended that you first evict the server from cluster membership. This
can be done through the Failover Cluster Management snap-in by expanding the console tree under Nodes, selecting the node, clicking More Actions, and then clicking Evict.
I'm sure there no cluster formed, so how can I remove it?
Thanks !

Hey I have the same problem,
Somehow cluster got installed on one node on windows 2008 R2 but it was not showing anything in cluster fail over manager wizard and cluster service is
not running
when I am trying to remove the fail over cluster it says
"This
server is an active node in a failover cluster. Uninstalling the Failover CVlustering feature on those node may impact the availability of clustered service and applications. It is recommended that you first evict the server from cluster membership. This can
be done through the Failover Cluster Management snap-in by expanding the console tree under Nodes, selecting the node, clicking More Actions, and then clicking Evict."
But there
is no cluster at all, I am not sure how remove it
So let
me know will that power shell command "clear-clusternode" fixes my problem?
and please
let me know do I need to run it in normal Power shell command line or Power shell failover cluster manager command line?

Multiple identical Windows 2008 Clusters for file sharing, how to create a failover, since DNS CNAME is not an option?

Hello,
We have multiple SAN devices that expose block storage to multiple Windows 2008 Storage Edition clusters, which consume them via iSCSI. To simplify, here is what we have:
machine1+machine2 --> cluster --> storage1 (accessible via
\\storage1.domain.name\shares)
machine3+machine4 --> cluster --> storage2 (accessible via
\\storage2.domain.name\shares)
The 2 clusters have replication from active (storage1) to standby (storage2), so in theory they both include pretty much all the files.
We have hundreds of applications that are pointing to \\storage1\shares. In case of a disaster, however, it is an immensely laborious task to change all the end-points from
\\storage1\shares to \\storage2\shares, and then back.
I was trying to declare a CNAME (\\activestorage) in our internal DNS, and point it to the
currently active storage system. I tried both an alias and an IP pointing to the cluster. However, when I try to access
\\activestorage\shares, I got an error that the network share does not exist. I have been reading about this, and now I understand that CNAMEs are not possible in 2008 and only allowed in 2012 for this particular purpose.
I also understand that I may have to register a CAP (Client Access Point) to create an "alias" for my storage. However, the CAP approach does not seem to address (or does it?) my initial problem - I am not looking to create an alias just for a
particular storage cluster, but rather for the
active storage cluster. This way, if disaster strikes, I can simply go and change an IP somewhere, and all the applications will starting using the standby storage system.
I realize that there is an extra administration of ensuring that the two clusters are identical from shares perspective, and that's something we are already doing. All I need is a clue into how to make this architecture work in a less painful way.
Thank you for your help,
Isaac

I think you got confused between DFS and DFS replication. The primary use of DFS is namespace virtualization. It also has additional components which aid in real time replication. You can opt to use only the name space virtualization and not the replication.
The following link may provide some detailed information about DFS in 2008 R2. As I said.. You may not want to sue DFS Replicaiton, but DFS Namespaces is a perfect fit for your requirement (and very simple to implement)

Error 0x80070490 trying to launch VM without SCVMM on Windows 2008 Server R2

Hello everybody,
I get a weird issue trying to launch a VM.
This is the current situation : I get a server, Windows 2008 R2. I've only install Hyper-V and Failover Cluster. I can create a VM but when I try to launch it, I get an error message into a popup (translated from french) : "The application encountered
an error during modification of 'vm_name' state". "'vm_name' could not be initialize". "Could not initialize machine remoting system. Error 'Element not found'. (0x80070490). "Could not find a usable certificate. Error: 'Element not found'. (0x80070490)."
So, I'm unable to launch my vm's.
I'm not using SCVMM yet. I want to resolve this issue before.
I read some articles and posts about SCVMM certificate issue but I'm not using SCVMM.
More fun, I read articles about this issue but on Windows 2008 Server (not R2) : problem resolved by a fix, unapplicable on my Windows 2008 R2 :)
I'm totalyblocked and ain't got no idea how I can resolve it.
If someone gets I idea ...
