• Microsoft Cluster in vSphere using RDM disks

  Gentlemen, I have doubts that sounds simple, but it is better to ask than to the hurt things.

  Here, in the company where I started work two weeks ago. We have two servers of files Windows Server 2012, both are part of Microsoft Cluster Services, these two servers are virtualized on VMware ESXi 5.5, each on a host, here we use vCenter HA and DRS.

  Well, these file servers 03 RDM disks connected to the fibre channel, storage only disks are online only on node 1, node 2 drives are present in the computer Manager, but marked offline.

  To my knowledge, my experience of simple Microsoft cluster, the disks must be online on all nodes for disaster recovery is quick, for example through cluster in Windows Server 2008 R2 and Hyper-V Server R2 of 2012 using iSCSI storage and always leave the disks online on all nodes.

  My question is: is there a reason why a node drives remain online and the other node is taken offline? Because of RDM technology?

  I can then do disks on node 2 as well as online without risk?

  I'm an environment that left another analyst configured, had never made Windows Server 2012 in virtualized VMware vSphere servers cluster using RDM disks, so made the questions, so instead of simply in clicking on node 2 of disks and makes them online it is better to ask before

  Thank you!

  Ivanildo, is the normal Windows Server Failover Clustering behavior, since it is an active/passive cluster architecture, where a single node read/write a disk at a time, and is not a problem due to the use of RDMS in vSphere environment.

  The bellow image show two discs a WSFC, where 6 disk Offline on that particular node and the 7 disc is online:

  

  And, do TRY not to put the disks as offline being online on another node through disk management, this task must be performed by using the Failover Cluster Management console.

• Microsoft Cluster Services - vmware

  If a virtual machine is running in 2008 and will be used for Microsoft cluster services, can drive BONE be thin commissioning?

  Hello.

  No, the disc format should be thick.  It is documented in the document "Setup for Microsoft Cluster Service and Failover Clustering".

  Good luck!

• Compatibility with Microsoft Cluster DRS

  OLA,

  Hello

  Microsoft Cluster works with DRS ?

  
  I found le VMware the site documents what to say Yes et others not . What would be le right answer ?

  Jones, disco os vc esta publicando cluster por iSCSI direto para o Windows e nao por Raw Device?

  Neste caso, esses disco nao aparecem na lista devices da VM, product?

  Dessa forma o snapshot deve funcionar, pq na pratica nao tem bus sharing nas configuracoes da VM. So don't o nao gerado nao sumergida os discos publicados por iSCSI snapshot.

• Physical-virtual MSCS (Microsoft cluster service)

  Hello

  I have 2 physical Windows 2003 servers (IBM Blade / SAN boot) and MSCS with SAN lun data.

  Now, I don't want to migrate cluster node1 virtual machine on ESX 3.0.1and stay node2 cluster on the physical computer.

  What worries me is what will happen with the data on these LUNS/disks when I map RDM (physical RDM compatibility) in ESX server?

  What is the safest way to a virtual node and not lose any data?

  THX

  Dejan

  the safest would be to create a 3rd node (virtual) and add this to the cluster and then expel the old physical node, rather than perform a P2V

• Break a Microsoft cluster and attends independent P2V in a VMware environment

  I searched and searched for the best possible, answering this question and can not find specific answers!

  I have a file server Windows Server 2003 in a 2 node cluster (active/passive) with resources on a San, and what I want to do is:

  1 remove the cluster and have all the resources on a single machine.

  2. rename the machine with the resources on the virtual server name (cluster name)

  3 do a P2V to the file server in my cluster vmware environment

  I have no problem with the steps 2 and 3, but remove the cluster and will strictly autonomous is my Goliath. What I have read, I need to move all resources to one node, then stop the cluster service on the other node, then delete the node. From there I don't know what to do. Help, please! I want to achieve in the coming weeks.

  Check this Microsoft kb article.

  Another option could be to create a new file server in a virtual machine and then attach the storage where the actions as a RDM.

  Options are always good.

  Good luck!

• Setting up Microsoft Cluster

  Hi all

  I followed this guide: http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-50-mscs-guide.pdf

  for the clutser installation program. My first RDM (virtual), SCSI 1:0 added Quorum disk. When I add the same drive my second node, I get this error message when turning on/off.

  "An unexpected error has been received of the ESX host turning on VM vm-329.
  Reason: Cannot lock the file.
  Cannot open disk ' / vmfs/volumes/4fa9769c-f8aaa808-ee31-00221924bc69/db07/db07_10.vmdk' or one of the snapshot disks it depends on.

  Any ideas?

  Do not mix the mode of physical and virtual compatibility for the RDM with 'Sharing of Bus SCSI' for the controller. In the case of a single host, the "shared SCSI Bus" for the controller (not disks) must be virtual.

• Initiators of software iSCSI Microsoft Cluster in guest

  Hi guys

  I have a client who have iSCSI Storage... now they want to create a cluster, but I read that only FC SAN is supported for RDM...

  but it seems that iscsi is supported as iscsi in guest...

  If someone knows the configuration for this?

  or is it as simple as:

  1. create iscsi volume of Quorum

  2. create iscsi for data volumes

  3 activate the iscsi initiator in Windows 2008 guest VM

  4 map these to W2008 VM iscsi volume

  5. create an another PortGroup-VLAN for the private heartbeat (is it necessary or the private sector can take thje same segment as the notrmal network)?

  Thank you very much

  Oh, sorry I didn't answer your original question.

  You are right, you must configure the virtual computer with 3 vNIC on 3 different subnets, then make sure that the public network is on top, when configuring the network order in the BONE (don't know where it was in 2008 for Windows, in Windows 2003 is configurable in the advanced network settings) Guest.

• Microsoft Cluster in a virtual environment

  Is it possible to run a Windows 2008 Failover Cluster in a virtual environment using ESX 3.5?

  Kind regards

  Daniel9999

  The Windows 2008 Clusters are only supported with vSphere.

  But if you have an iSCSI storage, you can use a solution 'unsupported' (but functional) using iSCSI initiator inside Windows 2008 SMV to point to a few LUNS shared.

• P2V microsoft cluster (file) with shared PV220s (SCSi) storage

  Hi guys

  I'm quite new in the VMWARE world. So please forgive my ignorance. If it's my third message in the last 2 days.

  Scenario: basically, we have a MS cluster running on two windows (our file server) server that is attached to the DELL PV220s matrix raid (scsi) with 11 drive running raid 5 config... Now it of almost complete @ 1 TB and also will be out of warranty soon.

  We want to virtualize these two servers (essentially the cluster), and then move all the data to the DELL EQUAlLOgic SAN we have on our site as well.

  Now, I've read that MS Clusters are supported in Update1 of VMware 3.5.

  So, how is it less setting this up. What I've read so this option seems like the next three - provide details of them my knowledge in VMware/SAN is very limited at present, but in the hope of picking up very soon.

  1 P2V cluster as it is

  2 break the cluster, then P2v each.

  3. create a new node 3 in VMware. (how we should go on the PV220s San data movement) - we should create a new volume-LUN of the SAN?

  I read that the signatures of discs cause problems etc..

  Please discuss your experiences and your thoughts on P2V ING a MS cluster.

  I'll be very be very thankful to you guys if you can answer because it will speed up our project.

  Concerning

  Hello

  Moved to the forum of the Virtual Machine and the guest operating system.

  Read http://www.vmware.com/pdf/vi3_35/esx_3/vi3_35_25_u1_mscs.pdf very very carefully before you P2V a cluster, there are things you need to do to create the virtual hardware correctly. If it were me, I would not use P2V but fresh start installs correctly configured virtual hardware.

• vCenter 5.5 cluster using Fibre Channel & MSCS (Win 2003)

  Hi all

  I need to create a Cluster of 2003 of Windows (MSCS) as well as storage Fibre Channel shared on vCenter Server 5.5.  I need to work so that if a server crashes, the second server goes into action and support.

  I have a two-node Windows 2003 R2 64 bit running on the same host.  Virtual machines are created with an operating system installed.  I use for Fibre Channel storage and I have created and attached 6 discs in thick eager set to zero.  I also created and configured two NICs (Public and private) on each node.  The shared SCSI Bus is set to "Virtual" on both nodes.  I managed to get the two nodes to market and both can see the 6 disks.  The disk configuration is identical between nodes.  All drive letters to even the SCSI virtual peripheral nodes (1:X).

  I have not yet created the Windows cluster.  The problem is that, in node 1 when I create a folder in one of the attached disks, I don't see this folder in the same drive in node 2.  Is it a problem, a bad configuration or is this a normal behavior?

  Are there any other setup that I should consider to make this work?

  It's the doc that I follow:

  https://pubs.VMware.com/vSphere-55/topic/com.VMware.ICbase/PDF/vSphere-ESXi-vCenter-Server-55-Setup-MSCS.PDF

  Thanks much for any help!

  Since you not yet configured the cluster, this is normal behavior. Go ahead and configure the cluster, then the software cluster will manage the discs... do what you try can cause data corruption.

  And after the configuration of the cluster, take in mind that the drive will be online to a single node by time, as the Microsoft cluster is an active/passive cluster, in this way you will be able to see the disc and online with the letter assigned only on the active node.

• ESXI 5.0 with Microsoft Windows 2003 lost RDM after reboot host Cluster

  Whenever I need to do maintenance on an ESXi host who has a 2003 microsoft cluster after the host is restarted all RDM Cluster Microsoft disks loses access to the RDM disks and displayed with 0 KB size. Only it is possible to restore the cluster off the second node of a Microsoft cluster and by removing and adding RDM disks. Someone already had this problem?

• MSCS on an active DRS Cluster HA?

  Hi all

  We are setting up a 6 host DRS activated cluster HA with a host as the host of the previous day. Two of our virtual machines will run MSCS cluster (with active and passive node). What we want is that:

  1 - Normal VM must be restarted on a host sleep by using cluster HA when an ESX fails.

  2 VM Normal should be vMotioned DRS decides.

  3 clusterises MSCS VM should restart on a host sleep by using cluster HA when an ESX fails.

  4 MSCS group of VM should not be vMotioned automatically. Must reside on the specific host.

  Are higher than 4 point if possible please confirm how we do. I'm a little confused that as per below document MSCS is not supported on active DRS cluster.

  Kind regards

  According to the doc of vmware, the installation program for the Clustering failover and Microsoft Cluster Service to Vsphere5 no problem when you use the DRS and HA together. but it takes only

  1 - two nodes must never operate in a single host for HA and DRS
  2. to do this you must create the rules below

  -HA, create a host of DRS group, and then create a group of Virtual Machine DRS, then A VM host affinity rule must be created, with a group of virtual machine DRS and a host of the DRS group.
  -DRS, create anti - affinity machine VM-virtual rules specify which virtual machines should be stored on different physical hosts and turn on strict application of the law of affinity rules virtual machine configuration

  Or you can also disable the DRS for these 2 nodes and enable only HA, but even once you must ensure for HA 2 nodes never operate in an ESXi host

• 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.
