Add DirectAccess 2012 R2 to DirectAccess 2012 Cluster

Does anyone know if it is supported or possible to add DirectAccess 2012 R2 to an existing DirectAccess 2012 cluster?
Hoping to use this approach to upgrade and to DirectAccess 2012 R2 without creating a new cluster and configuration.
Thanks

I've never tried it, but I don't know of any reason why it wouldn't work. Server 2012 and above handle NLB/clustering quite a bit differently than UAG did, where the nodes are really more individualized and there's not a "master/member" mentality
anymore. So when you add the new 2012 R2, if you experience problems with it or notice that no user sessions are flowing to it, you can simply remove it from the array again, and then you'll know for sure. :)
If I had an environment online right now where I could test this for you I would, but I would give it a try if you have the server ready to go. Just make sure that you install the Remote Access Role, and also the NLB feature, to your new server before you
try adding it to the array. You'll also need to have IP addressing and certificates in place on this new node before you will be able to join it successfully to the array.

Guide to migrating a HV 2012 cluster managed by VMM to HV 2012 R2 + VMM R2

Hello everyone,
I have a task on hand and even after searching the ‘net for quite some time, I have not come across a solution listed on one page. I hope this thread becomes a “Guide to migrating a Hyper-V 2012 cluster managed by VMM 2012 to Hyper-V 2012 R2 + VMM 2012
R2”.
My searches did find these useful threads but they do not have all the information I need:

So let me start by listing what I have right now:
I have a 4 node cluster running Hyper-V 2012 SP1 (the free, core edition).
It is currently being managed with SC VMM 2012 SP1.
99% of the VMs are running on CSVs cut off a Fiber Channel SAN. I have some VMs on local drives and they are not HA.
Everything is in production. I have around 90 VMs total.
I do have capacity to take up to two HV hosts out of the cluster and still survive just fine.
I also have two other spare servers which have no OS on them.
What I don’t have:
I do not have SCOM or DPM or any other SC component.
Well, I used to have SCOM 2012 but I uninstalled it and removed it. Long story, don’t ask! I do plan to install SCOM 2012 R2 at some point soon.
Here is what I want to do:
Upgrade both the cluster and VMM to 2012 R2 version.
This time, I want to use Server 2012 Datacenter edition (with GUI).
I plan to join the spare servers to the 2012 R2 cluster.
Here is what I have learnt up until now (and correct me if I am wrong):
The steps I need to take to accomplish all this are:
Upgrade VMM 2012 to VMM 2012 R2 version
Eject at least one host from the cluster
Install Server 2012 R2 on that server.
Configure a one server (or more, if possible) cluster running 2012 R2
Give that server the same old CSVs
Use the “Copy cluster roles Wizard” to copy VMs from old cluster to new cluster. However this will incur downtime.
I have not started doing all this because I am not 100% sure on some things.
Here is the list of my questions:
1. About step #1: Upgrade VMM to VMM R2 version
Is there any reliable / official guide out there for this? I have seen these on the net:
http://technet.microsoft.com/en-us/library/dn469607.aspx
http://www.systemcentercentral.com/migrating-from-vmm-2012-sp1-to-vmm-2012-r2-step-by-step-upgrading-to-2012-r2-series/
The problem I see is that none of them talk about upgrading a clustered scenario. Do I assume that the steps of upgrading VMM 2012 to 2012 R2 are the same with or without a cluster?
On the server I eject from the cluster, do I upgrade the OS or do a fresh install? I prefer doing a fresh install.
2. Is there a way of doing all this with no downtime?
I am worried about needing downtime for the last step “copy roles…”. I wish there was a way of migrating the roles (VMs) without any downtime.
3. Anything I need to worry about?
I wonder if I need to be careful about granting access to the CSVs to the new R2 Cluster. Will that cause any problem?
Any inputs on this topic are highly appreciated! I promise to update the first post so that it becomes a guide as I get corrections and inputs from everyone :-)
Thanks!

Time to tackle the actual Hyper-V Cluster migration:
So by this time, I have two nodes in the old Hyper-V 2012 cluster managed by SC VMM 2012 R2. I wiped out the OS on the other 2 nodes and installed Windows 2012
Datacenter on them. This time I am not installing the Core edition for Hyper-V. After working with Core for a year or so, I feel Core gives way too much trouble for very little gain.
Now I plan to follow a technet document which describes how to
migrate virtual machines from a Hyper-V cluster using Cluster Shared Volumes (CSV). Although this document does not describe VMM I think VMM should be able to use those migrated VMs. Here is this migration strategy in a nutshell:
Create a new cluster using 2012 R2
Present the existing CSVs to the new cluster.
Leave the disk offline on the new cluster.
Use the copy cluster roles wizard in Failover Cluster Manager to copy VMs from old cluster to new cluster.
Virtual machines are created on the new cluster but are not turned on.
Turn off the virtual machines and take the disk offline on the old cluster and then on the new cluster you need to enable the disk and start the virtual machines.
Hmmm…sounds pretty involved to me. Well let’s get on with it. First things first…in order to use this migration strategy we need to create a new cluster.
Here are the steps I took to create a new cluster:
Install 2 Windows 2012 R2 on the same 2 servers I ejected from the old cluster.
Correct drive letters of local hard disk drives and optical drives, if needed.
Update them.
Setup networking. Take care of main network, heartbeat for cluster and iSCSI networks (if applicable). Here are some best practices:
http://blogs.technet.com/b/askcore/archive/2014/02/20/configuring-windows-failover-cluster-networks.aspx
http://blogs.msdn.com/b/clustering/archive/2011/06/17/10176338.aspx
https://social.technet.microsoft.com/wiki/contents/articles/9711.hyper-v-network-design-configuration-and-prioritization-guidance.aspx
http://technet.microsoft.com/en-us/library/dn550728.aspx
Make sure your bindings order is correct. I had to correct mine because by default, the heartbeat network was at the top!
I also followed this checklist of Hyper-v’s best practices.
http://blogs.technet.com/b/askpfeplat/archive/2013/03/10/windows-server-2012-hyper-v-best-practices-in-easy-checklist-form.aspx
Much of the stuff in there is very relevant.
Add the domain account used for host management and the SCVMM service account to the local admin group on the 2 new servers.
Use SC VMM manager to install Hyper-V role on the two new servers. VMM can do that as a part of the “Add Host process”.
In VMM, right click on “All Hosts” and click on “Add Hyper-V hosts and clusters”. Go through the wizard and add the two new servers.
When I did this, it failed. I got three errors, Error 10441, Warning 10444 and warning 26179.
I logged into one of the new servers locally and from Server Manager >> Dashboard >> Add roles and features.
On the “create virtual switch page, I selected the NIC connected to the main company network (as this time I have only one NIC for the company network, you should have at least two).
Unfortunately, even this time I get an error: Access is denied: 0x800700005
This is very strange because I am already logged on as an admin here.
Now I started checking for windows updates. I remembered that the checklist above also has a set of recommended updates. There was a huge 890MB), cumulative update available KB2919355. I installed and restarted after that.
I also installed the feature “Multipath I/O” since I was getting the “warning 26179”.
After this installation, I ran windows update again. No available updates.
Now I went back to VMM. I really want to enable the Hyper-V role using VMM. So I repeated step # 8. Interestingly, this time I did not get any error. VMM rebooted the host automatically. Yay!
Now I repeated steps 14 to 16 on the second server. Worked fine!
At this point we are ready to create a new cluster using the two nodes. I followed this document:
http://technet.microsoft.com/en-us/library/gg610576.aspx
At this point I ran into a problem. I talked about it on my thread: When I try to create a new HV cluster using the "Create HV Cluster" wizard in VMM, it comes to a screen titled "Storage" where it shows all the existing LUNs as disks and
it says "select the discs you want to cluster". That is all good but at the bottom it says "Any data on the disks will be overwritten”. Of course I want to keep my data intact so I can use the copy cluster roles wizard later on! How can I create a new cluster
which uses the same disks as the old cluster WITHOUT wiping out the disks?
Ok so I did not get an answer on the forum, so I decided NOT to take a risk and do a quick test. Here is what I did: I masked/unexported all CSVs. Then I created a test CSV, put some data on it and proceeded to create a cluster using that
CSV and a quorum/witness disk.
This time on the storage page, For the test volume I checked the checkbox under CSV. I left the format boxes unchecked << THIS IS WRONG read below for updates
The attempt failed. Somehow the test CSV got configured as a local disk on host #1, it was showing up as NTFS instead of CSVFS. The VMM cluster creation process stopped. I found out that both the CSV and the quorum disk were online on the
node #1. I made them offline.
Retried , got the same error as last time : Mounts storage disk on (servername).
FINALLY I realized that step # 21 bove is WRONG! You need to select “Do not format” under the file system column. This will leave the CSV untouched.
Unfortunately, even this did not work. So I just took away ALL CSVs and tried to recreate the Cluster. It STILL did not work! LOL! The error is 25303
I corrected the permissions as this:
ON the HV hosts, inside local administrators group add VMM service account, Host admin account and VMM server’s computer account
Inside “Virtual Machine Manager Servers” group add VMM server’s computer account
Unfortunately, it still did not work! The error is 25303 (same). I looked everywhere including all the logs (system and security) nothing there. I searched on the net but never found a solution. Eventually I accepted defeat and tried to
create a cluster from outside VMM…using “Failover cluster manager”
Even then I got an error! It seems to me that it failed on creating the computer name of the cluster in AD.
I tried it again with a different computer name in AD…something which had never been created earlier (I had mistakenly created a computer name for the cluster and then deleted it). This time it worked! However I got an error that the witness
disk was not created because it does not have an acceptable file system. Hmmmm.,….I had not formatted the witness disk since I thought the cluster wizard will do it. I created a Witness disk later, manually.)
Interestingly, when I opened VMM again, I see the cluster in there and I am able to manage the cluster from within VMM…interesting!

Adding existing SQL Server 2012 to a New SQL 2012 Cluster

We currently have a SQL 20012 Server setup and running on our domain. We would like to switch this to a clustered environment. Is it possible to setup the new SQL 2012 Cluster and add the existing SQL 2012 server as a node in the cluster
without losing any functionality. All servers will be built with same drive letter.

No its not possible to convert standalone installation to cluster.Moreover first you need to configure Windows cluster then backup all SQL server databases logins jobs packages and install fresh instance of SQL Server in cluster aware mode

Sql 2008 r2 cluster side by side with sql 2012 cluster on Windows 2008 R2

We have a SQL 2008R2 active/passive SQL cluster running on Windows 2008 R2 cluster.
I would like to add a SQL 2012 clustered instance to the same Winows 2008 R2 cluster.
Are there any issues involved having a SQL 2008 R2 clustered instance running side by side with a SQL 2012 instance in same Windows 2008 R2 cluster?
Are there any pitfalls/"gotchas" to watch for with SQL 2012 cluster install?
Thank you so much!

Hello,
Two instances, one SQL Server 2008 and the other SQL Server 2012, side-by-side, is fully supported.
I would like to recommend you to assign a different port (not port 1433) to the non-default instance
to avoid an IP address conflict between both instances.
Hope this helps.

Windows 2012 cluster, CLIUSR cannot be created, password does not meet security requirements

Trying to create a Windows 2012 cluster (Not R2). The cluster creation wizard goes through without problems. However, after a few minutes the cluster service dies with EventID 1556 and error code 2245 "The
password does not meet the password policy requirements. Check the minimum password length, password complexity and password history requirements." The error repeats every few minutes.
Looking at the cluster log, we find:
ERR Workitem(Sweeper::Sweep) callback threw exception: (2245)' because of '[CLI] Account Creation failure: 2245, 4294967295'
ERR [CORE] Shutting down cluster service because of unhandled exception in a worker thread
It appears it is trying to create the local CLIUSR account, but the self-generated password does not meet complexity... The local password policy is the default deployed with Windows 2012 -
No unusual password requirement (8 characters with built-in complexity requirement)
I saw Elden's description of CLIUSR in
https://social.technet.microsoft.com/Forums/en-US/95929983-a50c-42b3-a520-6a171e542948/win-server-2012-two-node-cluster-local-cliuser-issue?forum=winserverClustering - so I believe I understand what it is doing, but how can it not generate a password complex
enough? And I do not see any report of anyone having this issue, so I suspect a local configuration / issue.

Hi FrankJB,
Please verify that the Cluster Service account has the appropriate user rights on each node of the cluster. The Cluster Service account must be
in the local administrators group and should have the rights listed below. These rights are given to the Cluster Service account during the
configuration of the Cluster node. It is possible that a higher level policy is over-writing the local policy or that an upgrade from a previous
operating system does not add all of the required rights.
If you can confirm your current account meet the cluster create conditions, please disable all your firewall then run the cluster validation and
post the warning and error information.

Can't back up VMs in 2012 Cluster 0x80042301

I have a 2012 Cluster with a CSV. I have the Dell Equallogic HIT v 4.5 installed on both nodes, as well as the SCDPM 2012 SP1 Agent. When I add a replica to DPM to back up one (or any) of the virtual machines on the cluster the vss writer for Hyper-V is
put in a bad state and DPM gives me the following error:
The VSS application writer or the VSS provider is in a bad state. Either it was already in a bad state or it entered a bad state during the current operation. (ID 30111 Details: VssError:A function call was made when the object was in an incorrect state

The following VSS errors are logged in the Eventlog of the Cluster Node:

. This is often caused by incorrect security settings in either the writer or requestor process.

Hyper-V guest SQL 2012 cluster live migration failure

I have two IBM HX5 nodes connected to IBM DS5300. Hyper-V 2012 cluster was built on blades. In HV cluster was made six virtual machines, connected to DS5300 via HV Virtual SAN. These VMs was formed a guest SQL Cluster. Databases' files are placed on
DS5300 storage and available through VM FibreChannel Adapters. IBM MPIO Module is installed on all hosts and VMs.
SQL Server instances work without problem. But! When I try to live migrate SQL VM to another HV node an SQL Instance fails. In SQL error log I see:

Does a sql server client application needs to be modified to allow it to have benefits of running on a SQL Server 2012 cluster?

I have a client application in c++ which interacts with sql server database. My question is whether I need to make any changes to the client application code to allow it to have the benefits of running on a SQL server 2012 cluster environment.
To elaborate more on my query my concern is for e.g if my application has called an api to execute a sql query and during
the execution of this query the sql server (part of the cluster) goes down then as per my understanding the sql cluster would ensure that another node takes up the task from the current sql server which has gone down. Is this transition transparent to the
client application or in such a case my client application needs to again make a new connection and again execute the query?

Hello,
Just as Shanky post above, When you connected to a database in an availability group and specify the availability group listener in the connection string, if the availability group fails over, the original connection is broken, your application
should try a new connection after the failover.
So, when connect to an availability group, please try to increasing connection timeout and implementing connection retry logic to increase the probability of successful connection.

SQL 2012 Cluster install - error msg

Hi
I am in the process of installing SQL server 2012 cluster, on the Instance configuration page where i gave "SQL Server Network Name" as "appsqlclsA" and the "Named Instance" as "Ins01". I am getting the below
error msg, i am not sure exactly what permissions i need.
"The SQL Server failover cluster network name "appsqlclsA" is not valid. The name must be a valid DNS and Wins name.
So what i understand is i do not have permission to create the virtual sql name account "appsqlclsA"" in the AD.
But i need help finding exactly what permission i need.
Thank you for your help

Take a look at this
TechNet article for assigning permissions in Active Directory to create the virtual computer object. Either you are granted the appropriate permissions or the virtual computer object be pre-staged prior to installation

SQL 2012 Cluster- How to or Steps to Move Tempdb Files from Local drive to Shared volume

Hi..
I did Installation of SQL Server 2012 Cluster. During this setup I installed Tempdb Files on Local drive. Now I want to move this tempdb files from local drive to Shared Drive . When I am trying to move I am getting below error.
Does any one can help me or provide the steps to move this tempdb files from local drive to Shared Drive ?
Msg 5184, Level 16, State 1, Line 1
Cannot use file 'Z:\Tempdb\tempdb.mdf' for clustered server. Only formatted files on which the cluster resource of the server has a dependency can be used. Either the disk resource containing the file is not present in the cluster group or the cluster resource
of the Sql Server does not have a dependency on it.
Thanks
Regards..
Please Mark As Answer if it is helpful. \\Aim To Inspire Rather to Teach

Hi,
The error message may be thrown out when you attempt to create a database on another shared cluster drive when the SQL Server resource is not dependent on that disk.
Check if you are in the scenario which mentioned in the following article:
How to create databases or change disk file locations on a shared cluster drive on which SQL Server was not originally installed

SQL 2012 Cluster Multi Instances !

Hello,
For SQL 2012 Cluster Multi Instances setup, Does the Storage Space should be different for each instance or can be the same?
Kindly help me in this.
Regards !

Hello,
The reason is that's what Microsoft decided to do. It's also that way because disks are a clustered resource and belong to a single resource group. Each SQL Server install will have its own resource group. If a disk could belong to more than one resource
group, and a group fails - then all of the instances with the same disk would fail. That's not what you'd want from an HA solution. Microsoft clustering is a shared nothing model to which this is part of.
Before installing:

◦The base drive, the one with the drive letter, cannot be shared among failover cluster instances.

Can I add windows 2012 R2 host to VMM 2008 R2?

We are running VMM 2008 R2 on Windows 2008 R2. When attempting to add a Windows 2012 R2 as host to VMM, I receive this message:
Error (2915)
The WS-Management service cannot process the request. Object not found on the mdnjdqgxd2.xxxx server.
(Unknown error (0x80338000))
Can I add windows 2012 R2 host to VMM 2008 R2? If yes, what could be the problem?
Bob Lin, MCSE & CNE Networking, Internet, Routing, VPN Networking, Internet, Routing, VPN Troubleshooting on http://www.ChicagoTech.net How to Install and Configure Windows, VMware, Virtualization and Cisco on http://www.HowToNetworking.com

The VMM Server should never have the Hyper-V Role enabled.
The VMM 2008 can only be installed on 2012:
http://technet.microsoft.com/en-us/library/gg610562.aspx#BKMK_SupportedOS
You need to look at the support matrix of the SCVMM version and the Hyper-V Server Version.

In this case it is beyond 'support' it is what actually will work.

Backups - Transactional Logs - 2012 Cluster Always On

Hi,
We have a SQL 2012 cluster that we can successfully perform a full backup of databases however we cannot seem to perform transactional logs backups. The databases are in FULL mode yet no success when using a maintenance plan.
any ideas?
Mark

Hi Mark,
There are some known issues with using the maintenance plans on Availability Groups such as the ones defined below.
Maintenance Plan Does not Backup Database or Log of Database Defined in Availability Group
Database Backup Maintenance Plan Fails on backup verify when running on
an Availability Group primary replica
To implement effective backups on Availability Group, you can customize you own stored procedure to backup the database and create SQL Server agent jobs on each replica. For more details,please review this blog:
Backing Up SQL Server Databases Participating In AlwaysOn Availability Groups.

Can I add a 2012 R2 server to a 2008 SP1 DFS?

I have a DFS system on a Server 2008Stnd SP1. I am adding a new VM Server 2012 R2 server at my data center. I want to add my 2012 server to the DFS and remove the 2008 server after it syncs. I will add a new 2012 server at my main site later. Can this
be done? Or can I add a new DFS using the 2012 server?

Yes you can.
You can add your Windows Server 2012 to current DFS replication group and remove the Windows Server 2008 after replication finished. However it is recommended to do a pre-staging instead of waiting for the initial replication as it will take a long time
if data size is large.
And creating new DFS namespace is also fine on that Windows 2012 system.

Add additional IP to Windows 2008 SP2 Cluster

Dears,
I have a 2 node SQL 2008 Cluster 64bit (non r2) on Windows 2008 SP2 64bit (non r2) Server.
I need to add additional IP (different subnet) to the Cluster Quorum Resource.
Kindly guide me the steps to add the IP ?
Thanks
Tariq

HI Tim,
Well we need more than one IP address on the Cluster (Quorum) for our replication to work as for some reason we cannot use the production IP which is currently configured for this Cluster.
Further if you are doing multi-site cluster with different subnet then you may need two IP with different subnet on the cluster (not for services or application)
I found this usefull command and it worked on the win 2008 sp2 (non r2) server:
C:\>cluster . res "FS IP Address" /create /group:"file server" /type:"IP Address" /priv address=192.168.1.106 subnetmask=255.255.255.0
For win 2008 r2 servers there is powershell command through which we can achieve the same.. :)
it took me hard time to figure out that "failoverclusters" module will not work for win2008 SP2 server.. !!
Thanks
