• Replication Failover clustering & Hyper-v on a two-node cluster

  Hello

  We have two identical servers.  One to use as a main server, which houses two virtual machines.  The other should be used as a back up in case the main server is not somehow.  We planned on using a solution of third-party software to back up our virtual machines and launch them in the event of failure of the principal server.  However, we discovered just gave the failover clustering in Windows Server R2 2012.

  We have tried to set up a cluster 2 nodes, with our virtual machines properly replicated to the backup server.  Excited by the present, we tried then to simulate failure of the primary server (by pulling on the cable network).  We were a little disappointed to find that the backup server is not automatically run virtual machines.  We did a survey and read than a solution of two nodes requires storage space for additional network (in addition to our two servers).

  I wonder if that's okay?  In other words, a two-node failover cluster requires separate network storage space.  If this is not correct, can someone point me to a set of instructions to correctly configure a two-node failover cluster that will automatically launch the virtual machines on the server backup (in the case of a failure of the principal server).

  Thank you

• Can I use ASM / ME to windows server 2012 file server failover clustering?

  Hi all

  Can I use ASM / ME to windows server 2012 file server failover clustering?

  We can use it with exchange, sql, sharepoint,..., but I can't find any document for file server.

  Thank you.

  HIT / working ME with CSV W2K12/R2, W2K8 CSV volumes cannot bear not to cancel the MAPPING is the main difference.  But HITTING / will allow ME to create the active copies and replicas of volumes CSV

  Yes the cluster file shares are supported with SUCCESS / me.    If you think about it, SQL, Exchange are indeed a "sharing".   Because it is an NTFS volume with services that run against her.  SQL, Exchange or fileshare services.

• ESXi HA and SQL Failover Clustering - resolved

  Dears

  My current environment is

  3 5.5 Esxi with active HA hosts

  Requirement;

  I prepared 2 R2 2012 Windows of the virtual machine and I need to build a node two SQL cluster on them. (with WFCS) and I was reading the article for taking in charge option and discovered I need activation were of affinity

  VMware KB: Microsoft Clustering on VMware vSphere: guidelines for supported configurations

  I got confused and lost on how to enable these options on HA only clusters.

  grateful if someone could share their experience in this regard,

  DRS requires vSphere Enterprise license. This is the reason why it does not show these options in your environment. vSPhere HA requires vSphere Standard edition. As you have the standard version, you are able to configure HA.

  There is NO as such impact.

  1. you use MSCS as a cluster of virtual machines & if anything happens to the clustering configured application, MSCS are switched to another VM in the MSCS cluster.  (I'm assuming you use IPC config. Cluster in a box)

  2 vSphere HA allows you to give an extra level of HA at the host/VM level. As you use your virtual machines to the MSCS cluster on top of guests. vSPhere HA is additional HA.

  3. in the case, host fails, vSphere HA are toggled MSCS grouped all VMs to other available inside the HA cluster host vSphere. That is to say it will restart all virtual machines on the other host. Please note that the restart of a virtual computer will have minimal downtime. In this case, as all virtual machines are on the same host, same MSCS cluster will have same downtime as vSphere THAT HA will have. But if you use CAB (Cluster in the box) as MSCS configuration, you can minimize interruptions of service MSCS VMs.

  4. in the case, VM itself fails (no host), vSphere HA will restart the VM has failed on the same host. In this case MSCS are switched all your app on the other virtual machines in the MSCS cluster.

  You have only vSPhere HA without Drs It should be good. Just as DRS gives you more flexibility.

  Please note that in any HA solution, in case of failure, you will come across with minimal downtime (time may differ across different solution HA).

• Microsoft Windows 2008 R2 failover clusters

  I read the documents of VMware where Windows 2008R2 failover cluster installation options can be "in a box" or "out of the box '.   There is another, but I need to have two virtual knots.

  In the option "outside the box", it indicates that the shared drive must be a FibreChannel drive.   Is this correct?  Can this be any other type?

  It depends on the version of vSphere that you use. FC has been the only way supported up to vSphere 5.1. With vSphere 5.5 support for iSCSI and FCoE was introduced. See http://kb.vmware.com/kb/2052238

• Microsoft Failover Clustering - issue of persistent reservations

  Hello

  I am trying to set up a fresh Win 2008 R2 failover cluster on my 5.0 ESXi hosts and unfortunately the verification of the cluster fails with an isssue of persistent reservation.

  I follow all the kb articles and white papers correctly build 2 VM of the client as follows:

  Windows 2008 R2 Enterprise SP1

  NIC for public traffic

  NETWORK map for the private heartbeat traffic

  Disk EagorThickZero for system

  RDM added in physical compatibility mode

  Controller SCSI (1:0) used in physical mode for both nodes

  Storage matrix that I use is a 5300 VNX

  I have Powerpath 5.7 running on each host ESXi

  Does anyone have an idea where this problem?

  I have attached the below error message.

  

  Hello

  The two guests are running on the same host? Have you tried posting when they are running on different hosts?

  Is something I can't work on my own how this file: http://www.VMware.com/PDF/vSphere4/R40/vsp_40_mscs.PDF

  Is part of the roadmap of documentation: http://www.VMware.com/PDF/vSphere4/R40/vsp_40_esx_roadmap.PDF

  Should I just consider that last?

  Thank you

  It has to do with availability solutions.

  You can protect aid comments clustering or using the solution services that protect the virtual machine (such as VMware HA and VMware FT).

• MS failover clustering Windows 2012 R2 on ESXi 5.5 overall of boxes (Cluster in boxes)

  Hi all

  Sorry if this noob question. I did search but geeting contradictory information.

  I want to install MSCS (using W2K12 R2) on the two machines of ESXi 5.5. I shared the storage through CF. It seems that doing CAB (Cluster across boxes) I have to configure my disks shared as RDM. I was wondering if I can do this with a simple shared VMDK disk. The VMDK disks reside in a shared data bank (Fibre Channel).

  Is this supported? Or a simple shared VMDK disk is supported only for the CIB (Cluster in a box)?

  Thank you!

  fix. Together in a box, it will work.

  Cluster in the box, you still need physical rdm mode (scsi controller).

• Services of files in Microsoft Clustering with failover in ESXi 4.1

  Helllo,

  I have a virtualization environment with 5 hosts ESXi 4.1 on location A and two hosts ESXi 4.1 location B, all with high availability, which is the host 7 ESXi 4.1 are highly available.

  I need to set up a file of Microsoft with Failover Clustering in ESXi 4.1

  I want to create a file from Microsoft with Failover Clustering with 3 VMs that are 2 VM on a location and 1 VM on site B.

  Geographic VM cluster is supported by vmware?

  What is the maximum nodes in the cluster in guest virtual machines?

  Thank you

  jVidalll

  Welcome to the community,

  Only 2-node MSCS is supported in ESX (i)

• Problem of cluster Failover MS after physical RDM conversion to VMDK

  Hello

  Last week I had to migrate 7 x 2-nodes virtual MS Failover clusters to a new data center. All clusters have been configured with the configuration of the cabin and all shared disks were in physical RDM mode.

  The target data center does not RDM disks so I had to convert all RDM disks VMDK files and use config before the migration of the IPC.

  I used vmkfstools to convert VMDK eagdrzeroedthick RDM files.

  5 clusters have been migrated successfully, but two cluster got strange question even if the procedure for all groups was the same.

  So in two groups, I have a problem where the second node in the cluster can not put online some of the shared disks. The first nodes in the clusters have no problem with the disks/SSP.

  But when I try to failover of all services, the second node may not bring online disc 1 or 2 shared, even if she can put the other shared disks online.

  VMKernel.log is not errors or warnings. I checked the configuration of virtual machines and everything seems OK.

  Any ideas what I could check?

  Just in case anyone else is facing the same problem.

  I could not find the root cause of the problem, even if it's without a doubt the conversion that triggered the problem. However, we found quite a simple solution - added new shared VMDK files, copied the files over and replaced the defective discs.

• Is Microsoft Failover Cluster ESXi 4.1 Shared Disk of NFS data store, it supported?

  Is Microsoft Failover Cluster ESXi 4.1 Shared Disk of NFS data store, it supported?

  We have a request from MS Failover Cluster configuration on Windows 2008 R2 2 guests with a storage shared for a web application. However, there is no VMFS storage of data or the ability of the CF to presending RDM. So, I created the disks shared on a NFS datastore using option "Setup for Failover Clustering and Microsoft Cluster Service" and have added the cluster disk and tested successful failover.

  But the MS cluster validation control cancelled storage and I want to know if that configuration is not taken because of supported.

  A notice would be useful.

  We are also working on setting up a cluster of ESXi for iSCSI storage, which can be leveraed for this purpose.

  Shyam-

  Its not supported.

  4.1, your only options supported are:

  • CF storage with pRDMs
  • iSCSI storage with initiators guest.

• Is there anyway around this limitation? -> Clustering on disks, iSCSI (VMware ESXi)

  This is in the article (http://www.vmware.com/pdf/vsphere4/r40_u1/vsp_40_u1_mscs.pdf): Setup for Microsoft Cluster Service and Failover Clustering

  Environments and the following features are not taken in charge for the setup of MSCS in this version of vSphere:

  • Clustering on iSCSI and NFS FCoE disks.

  Is this in any way about this?

  I would like to create a simple 2-node, Windows 2008 active/passive cluster in VMware ESXi using my FAS2020 iSCSI solution.

  Thanks for your time in advance!

  As I said earlier. Treat your virtual machines and physical and use the iSCSI initiator in the operating system.

• Creating a failover cluster Windows 2008 on ESX 3.5

  Hello

  I would like to create a cluster Windows 2008 on ESX 3.5.  As I understand it browse the forums supporting parallel SCSI as a type of shared bus was abandoned for Failover Clustering in Windows Server 2008.  To enable clustering, you need to use iSCSI on a target server.  Additional costs of license option for the introduction of a target server.

  Is ESX 3.5 update to support Windows 2008 failover clustering?  If so, when?

  Is there another solution that involves no additional cost?  I watched StarWind but the free version does not give us enough resources that is necessary.

  How ESX 4.0 supports Windows 2008 failover cluster?

  Thank you

  Brian

  In ESX 3.5, you can do a 2008 failover cluster with a software initiator in the node Windows 2008.

  For ESX 4 no problem.

• Windows Server 2012 R2 - configuration redundant server

  Hi all

  I am setting up two servers for a company and trying to set them up so that if omitting server01, server02 will resume all requests for service.  I tried to use failover clustering, but we were hoping that we could use the storage we have in servers (we installed 2 3TO drives in each and in the opposite direction of their), and failover clustering requires an external storage Center.

  The two servers running Windows 2012 R2.  Initially, Essentials has been installed on them, but they have since had the keys to standard product enabled, providing the functionality of the standard on the generation of an Essentials.

  Also, note that the service is not a standard Windows service, but an application.  Is also to be noted that we are not interested in the use of virtual machines of any kind (without Hyper-V, VMWare or Virtual Box).  The company is currently using old servers running XenServer, and we had problems with them.

  Any help is appreciated.  Thanks in advance.

  This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)
