Windows 2008R2 Failover Cluster node

I am new to this company and have been asked to take over a task that the previous employee left unfinished. I am "familiar" with Failover clustering but have not done any recently. It looks like the previous employee evicted one
of the 2 node cluster servers to replace the hardware. I've setup the new hardware with Failover cluster but now need to setup the iSCSI volumes on this new node. I have not done this before. All I've done before was create NEW failover
disks and those were Fibre Channel disks. Can anyone give me advice or a link to a tutorial to setup these existing iSCSI volumes on the second node? One more note: the iSCSI volumes are on a Dell EqualLogic system and I've never worked
on EqualLogic before either.

Hi,
If I doesn’t misunderstand it seems you are finding how to setup the fiber channel storage to the node, you can refer your hardware manual to setup the hardware connection,
or call your hardware vendor for the more help, you can refer the following support scenario to configure your fiber channel storage:
The Cluster service allows you to reconnect or replace a cable between the HBA and the switch, and then allows for the node to take ownership of the physical disk resource.
The HBA driver must consider several issues for a Plug and Play rescan to occur. The HBA miniport driver must issue a "BusChangeDetected" notification when the cable is reconnected (an HBA port driver issues an "IoInvalidateDeviceRelations" notification) so
that Windows is notified that a change has been made to the shared bus.

How to Perform Forced Manual Failover of Availability Group (SQL Server) and WSFC (Windows Server Failover Cluster)

I have a scenario with the three nodes with server 2012 standard, each running an instance of SQL Server 2012 enterprise, participate in a
single Windows Server Failover Cluster (WSFC) that spans two data centers.
If the nodes in the primary data center are unavailable due to data center outage. Then how I can able to access node in the WSFC (Windows Server Failover Cluster) in the secondary disaster recovery data center automatically with some script.
I want to write script that can be able to check primary data center by pinging some IP after every 5 or 10 minutes.
If that IP is unable to respond then script can be able to Perform Forced Manual Failover of Availability Group (SQL Server) and WSFC (Windows Server Failover Cluster)
Can you please guide me for script writing for automatic failover in case of primary datacenter outage?

please post you question on failover clusters in the cluster forum. THey will explain how this works and point you at scipts.
You should also look in the Gallery for cluster management scripts.

You are trying to implement manually what should be happening automatically in the cluster. If the primary SQL Server becomes unavailable in the data center, it should fail over to the secondary SQL Server automatically. Is that not working?
You also might want to run this configuration by some SQL experts. I am not a SQL expert, but if you have both hosts in the data center in a cluster, there is no need for replication between those two nodes as they would be accessing
the database from some form of shared storage. Then it looks like you are trying to implement Always On to the DR site. I'm not sure you can mix both types of failover in a single configuration.
FYI, it would make more sense to establish a file share witness in your DR site instead of placing a third node in the data center for Node Majority quorum.

FTP in Windows 2012 Failover Cluster

Hi,
Understand that Windows 2012 is having much improved Failover Clustering features,however i have faced issues when i configured FTP in Windows 2012 Failover Cluster.
1) As per the process configured the shared disk for FTP data path.
2)Installaed FTP feature in both Nodes of Clustert
3)Finally created the Generic Service in Cluster Roles for FTP Service.
After the configuration i found everything working fine but when i try to failover the FTP role found that FTP resource is not moving smoothly. Also i observed that Microsoft FTP service gets in to "starting" mode in the destination Node. To run the FTP
resource Microsft FTP service should be in Started mode.
This happens only when we try to failover else it works fine if you start freshly.
Have any one tried this? Any clue about such issue ?
Regards:Mahesh

Hi,
In earlier versions of Internet Information Services, Microsoft provided generic resource monitor components to support high availability Web server instances by using the Microsoft Clustering infrastructure. However, custom code was needed to fully realize
the potential of this solution. Also, the generic scripts that Microsoft provided did not satisfy customer needs.
From IIS 7 to configure IIS in a clustered environment by using Windows Server failover clustering, you have to use a custom (scripting) code to enable such a high availability scenario.
Note:
We recommend that administrators carefully evaluate the use of Network Load Balancing (NLB) instead of using failover clustering as the primary and preferred method for improving the scalability and availability of Web applications that have multiple servers
that are running new IIS (from IIS 7) . One benefit of NLB is that all servers can actively participate in the concurrent handling of incoming HTTP requests. Another benefit is that in an NLB IIS environment, it can be much easier to support rolling updates
and rollbacks while still providing high availability of Web applications.
To configure high availability for IIS FTP servers using Failover Clustering:
Install the Web Server role on all cluster nodes.
Install the Failover Clustering feature on all cluster nodes and create the cluster.
Set up a file share that will be used for IIS shared configuration
Configure the IIS shared configuration on all cluster nodes
Configure Offline Files for IIS Shared Configuration on all cluster nodes
Configure the FTP site and specify the location of its content on one cluster node
Configure high availability for your FTP site by creating a generic script in Failover Cluster Manager
For more detailed configuration procedure please refer to following MS articles:
Note: I didn’t find IIS 8 in Windows Server 2012 failover cluster configuration guide, below guide was published for II 7 in Windows server 2008 and Windows Server 2008 R2, but its basis configuration procedures should also apply to Windows Server 2012.

The lease timeout between avaiability group and the Windows Server Failover Cluster has expired

Hi,
I am having some issues where I get a lease timeout from time to time. I have a Windows 2012 Failover Cluster with 2 nodes and 2 SQL 2012 Always-on Availability Groups. Both nodes
are a physical machines and each node is the primary for an AG.
From what I understand if
the HealhCheckTimeout
is exceeded without the signal exchange the lease is declared 'expired' and the SQL Server resource dll reports that the SQL Server availability group no longer 'looks alive' to the Windows cluster manager. Here are the properties I have setup
which are the default settings:
LeaseTimeout - 20000
HealthCheckTimeout - 30000
VerboseLoging - 0>
FailureConditionLevel – 3
Here are the events that occur in the Application Event Viewer:
Event ID 19407:
The lease between availability group 'AG_NAME' and the Windows Server Failover Cluster has expired. A connectivity issue occurred between the instance of SQL Server and the Windows Server Failover
Cluster. To determine whether the availability group is failing over correctly, check the corresponding availability group resource in the Windows Server Failover Cluster.
Event ID 35285:
The recovery LSN (120881:37533:1) was identified for the database with ID 32. This is an informational message only. No user action is required.
SQl server logs are too long to post in this box but I can send them if you request.
The AG is setup to failover automatically but it did not failover. I am trying to figure out why the lease timed out. Thanks.

From what I've been able to find out, this is due to an issue with the procedure sp_server_diagnostics. It sounds like the cluster is expecting this procedure to regularly log good status "Clean" in the log files, but the procedure is designed not
to flood the logs with "Clean" messages, so only reports changes, and does not make an entry when the last status was "Clean" and the current status is "Clean". The result is that the cluster looks to be unresponsive. However, once it initiates
the failover, the primary machine responds, since it was never really down, and the failover operation stops.
The end result is that there really never is a failover, but the database becomes unavailable for a few minutes while this is resolved.
I'm going to try setting the cluster's failure condition level to 2 (instead of 3) and see if that prevents the down time.

Windows 2012 Failover Cluster - File server role (vCO)

Hi,
I wonder if anybody can shed some light on a query i have.
A windows 2012 failover cluster will be built in AD domain example.uk. Cluster File server roles will be created and will reside in this domain also.
We also have a requirement to run a cluster file server role in the child domain off secure.example.uk. Is this possible? or do the file server roles and related vCO's have to reside in the same domain as the cluster (CNO).
I know the CNO can be used to create the VCO but could a prestage a VCO in the child domain of secure.example.uk.
Mark

Hi Mark,
By default CNO will create
VCO automatically in default domain computer OU, we generally use the
KISS principle to place the CNO and VCO to the same OU, and as far as I know there no known design document indicate the VCO can be placed in different domain, therefore I suggest you place the CNO and V CO at same OU.

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

Failover cluster node - You do not have administrative privileges on the server 'servername' ?

Hi Hello & Good morning Technet's,
I would like to post a question which i really expecting a solution.
I got 2 domain in one single forest.
Domain 1: hg.corp
Domain 2: iac.corp (iac.corp
is a tree domain under hg.corp forest)
Trust : Transitive
trust between hg.corp and iac.corp
Domain controller 1: dc.hg.corp
(for hg.corp)
Domain controller 2: iacdc.iac.corp
(for iac.corp)
I want to make a Fail-over cluster between this 2 domain controllers ( But both are in different domain literally, but in same forest )
Process Validate cluster in dc.hg.corp
dc.hg.corp can added, but iacdc.iac.corp failed (Error: You do not have administrative privilages on the
server 'iacdc')
Process Validate cluster in iacdc.iac.corp
iacdc.iac.corp can added, but dc.hg.corp failed (Error: You do not have administrative privilages on the
server 'dc.hg.corp')
Technet please provide me a solution for this issue, So i can reduce server box counts.
Thank you & Have a nice day.

Hyper-V Failover Cluster Node Corruption

Dear All,
Some of my nodes are showing abnormal behavior. They are restarting every now and then. I had updated the cluster nodes, but all updates were OS specific, there was nothing specific
with respect to hardware update.
I have analyzed crash dumps and find out that following is causing the crash:
page_fault_in_nonpaged_area
anyone has any idea about this?
Thanks in advance.

Hi ,
What is the OS of the cluster node ?
Did you try to remove the protection client for troubleshooing ?
If it is a 2008R2 cluster , please refer to this thread :

Disk Remove from 2008R2 Failover Cluster

I have a two node Windows 2008 R2 Failover Cluster with only the File Services Role. There are multiple disks on this server, presented by an EMC storage array via FC. I would like to remove one disk that is no longer in use. The disk is currently in available
storage in the cluster and is in an offline state. The dependency report for the disk shows no required dependencies, no 'AND' relationship, no child resources, and no 'OR' relationship.
When I attempt to remove the disk from available storage I receive the warning "This resource has other resources which depend on it. Deleting it will cause those resource to go offline. Are you sure you want to delete Cluster Disk #?"
How can I determine what resources are dependent upon this disk when the report shows no dependencies? And, since the disk is in an offline state and in available storage, if there are dependencies how are they not in a failed or offline state as well?

Hi,
If the disk resource is offline for some time and you make sure it’s no longer in use. You may remove the disk resource in cluster. You may try below command:
Launch command prompt with elevated privilege.
cluster resource
>> Display the status of a cluster resource
cluster resource “resource name” /listdep
>> list the dependencies for a resource
cluster resource “resource name” /fail
>> initiate resource failure
cluster resource “resource name” /delete
>> delete a resource
Try above command and give us feedback for further tourbleshooting.

Windows Server Failover Cluster Tahniques

We have Two Servers Ready to be Deploy the SQL 2012; Need to make Cluster of These two nodes.
We have Servers with 900 GB Unallocated local Disk Space in each server.
We Don't have any kind of Shared Storage.
My Questions are:
- how to make Qourum?
- How to Use these Two Disks on each server so that Data will be Replicated?
- After Making the Cluster, how to Install the SQL server?

Hi,
The shared storage is necessary for the failover cluster, if you don’t have the share storage you can’t build the failover cluster. The two node local disk space can’t be
used as the CSV storage.

Having a problem creating 2 node cluster. I launch FCM, begin the process of adding nodes. Node 1 goes in fine. Node 2 gives an error which is, "unable to connect to xxx.xxxx.com via WMI. This may be due to networking issues
or firewall configuration.
Node 1 and 2 are virtual. Have tried them on the same metal and on different metal.
Any advice would be much appreciated.

Hi shageman0304,
Unfortunately, the available information is not enough to have a clear view of the occurred behavior. Could you provide more information about your environment. For example,
the exact text of any error? When this problem occurs the system log record information, screenshots is the best information.
If you have install any third party software on this node please disable or exit them, please install the Recommended hotfixes and updates for Windows Server 2012-based failover
clusters updates then monitor this issue again.
Recommended hotfixes and updates for Windows Server 2012-based failover clusters
http://support2.microsoft.com/kb/2784261
After install the updates, if the issue still exist please performing the following steps:
1. Open Task Manager on the affected server and check if the wmiprvse.exe is running if not please enable the wmi service.
2. Restart wmi service.
3. Restart the server.
Please rerun the validation test then post the error part, that report will quickly locate the issue.

Perform Forced Manual Failover of Availability Group (SQL Server 2012) and WSFC (Windows Server Failover Cluster)

I have a scenario with the three nodes with server 2012 standard, each running an instance of SQL Server 2012 enterprise, participate in a
single Windows Server Fail-over Cluster (WSFC) that spans two data centers.
If the nodes in the primary data center are unavailable due to data center outage. Then how I can able to access node in the WSFC (Windows Server Fail-over Cluster) in the secondary disaster recovery data center automatically with some script.

Can you please guide me for script writing for automatic fail-over in case of primary data-center outage?

+1 to David's comment. I would not suggest to run a script automatically. During such failover you might have data loss and decision has to be made with business owners during disaster.
During such situation, you need to start cluster service in force quorum mode (/fq switch) and then perform manual failover of AG to DR site.

Apply SP1 to SQL 2012 clustered on a Windows 2012 failover cluster

For earlier versions of clustering there was an ability to prevent a resource from failing to a particular node. I used this when service packing clusters to ensure that no SQL instances would attempt to fail back to the node I was patching. That ability
doesn't seem to exist anymore. ANd pausing or stopping a node causes rule failure in the SP setup.
Has anyone successfully performed this patching and are there any best practises or tips to follow?
Regards, Matt Bowler MCITP, My Blog

Hello Matt,
This is still available, though I'm not sure where you remember it being. You can choose individual resources in a resource group and can also do it at the resource group level as well. It's in the properties of each level and allows each resource or resource
group to be allowed to run on only the nodes selected.
Here is the KB on it (though they use the command line):
http://support.microsoft.com/kb/958734
I'd patch the instances on the nodes that the instance is not currently active (if more than 1), pause the node and reboot if necessary. Continue rolling until services need to be moved or your patched nodes outweigh your unpatched nodes at which point I'd
move the services and patch all remaining nodes.
