Hyper-V Core HA Cluster

Hi, 
I am bulding a Highly available cluster from two Hyper-V 2012R2 core nodes and need to clear some things.
I would like to know, how to solve AD, when I need the domain controller Highly available.
I thought I would have one domain running on a separate server (third server, not a node of a cluster), just for the cluster and Hyper-V services and a second one, running the whole Company domain.
Can this be solved another way? E.g. installing full WS2012R2 as nodes and using them as domain controllers? I would like to avoid having another server running. 
Thank you.

will the virtual AD DC always be up earlier than the cluster? I was told, that without AD alive the cluster will not start.
It's a safe assumption that 1 of the 2 hosts will be up at any given point in time. Which means 1 AD DC is up as well. I don't see a scenario where the cluster is unable to start due to absent AD. If both hosts are down, there would be no cluster to start. 
I recommend using a quorum disk for the cluster regardless of the number of nodes.

  • Migrate from server core 2008 r2 hyper-v with failover cluster volumes to server core 2012 r2 hyper-v with failover cluster volumes on new san hardware

    We are getting ready to migrate from server core 2008 r2 hyper-v with failover cluster volumes on an iscsi san to server core 2012 r2 hyper-v with failover cluster volumes on a new iscsi san.
    I've been searching for a "best practices" article for this but have been coming up short.  The information I have found either pertains to migrating from 2008 r2 to 2012 r2 with failover cluster volumes on the same hardware, or migrating
    to different hardware without failover cluster volumes.
    If there is anyone out there that has completed a similar migration, it would be great to hear any feedback you may have on your experiences.
    Currently, my approach is as follows:
    1. Configure new hyper-v with failover cluster volumes on new SAN with new 2012 r2 hostnodes and 2012 r2 management server
    2. Turn off the virtual machines on old 2008 r2 hyper-v hostnodes
    3. Stop the VMMS service on the 2008 r2 hostnodes
    4. copy the virtual machine files and folders over to the new failover cluster volumes
    5. Import vm's into server 2012 r2 hyper-v.
    Any feedback on the opertain I have in mind would be helpful.
    Thank you,
    Rob

    Hi Rob,
    Yes , I agree with that "file copy " can achieve migration.
    Also you can try "copy cluster wizard " :

  • Hyper-V Core and OWIN/Katana web app

    Hi, Is it possible to run an OWIN/Katana app on Hyper-V Core?
    Best Regards Biagio Paruolo Italy

    Actually, with one server being Intel and the other being AMD, you cannot cluster them.  Nor can you do live migration because of the different processor types.
    In regards to the management of the Hyper-V hosts, it is much easier to keep them both in the same domain.  You can manage them if they are not part of the domain, but it requires more set-up, so I would keep them in the domain, particularly for your
    home lab.
    As for best practices, here is a good blog post -

  • Upgrading Hyper-V Server 2008R2 Cluster to 2012R2

    I have a Hyper-V Server 2008R2 (free 'core' version) cluster that I would like to upgrade to Hyper-V Server 2012R2 (same 'core' version).  I found
    this document that seems to outline the process, however I have the following questions...
    Any reason this process won't work on the "core" version of Hyper-V.  i.e. "Microsoft Hyper-V Server 2008R2".  I currently have a 2-node 2008R2 HA cluster with "core" servers and am looking to migrate that cluster
    to the "core" version of 2012R2.
    Is there no way to do this "in place", meaning without a dedicated target server?  It seems like the process assumes you just have extra servers sitting around that can act as targets.  I suppose I could shuffle VMs off one cluster node,
    evict that node from my current cluster, rebuild it with 2012R2 core, add it to a new cluster as the only node and carry on with the process outlined here?  Once all VMs are on the new "cluster" of one 2012R2 node, I would destroy the original
    cluster, rebuild those machines with 2012R2 and add them as nodes to the new cluster?
    Any reason the "Failover Cluster Manager" tool, version 6.1, I've been using to manage my 2008R2 environment won't work to do the migration?  Or are there new 2012 tools I need to have installed on my workstation.  Remember, since this
    is the "core" version I can't manage anything from the server.
    Thanks,
    Todd

    Here's an update on what happened...
    The first VM that failed turned out had 1 snapshot, which I know is a no no, but I generally never snapshot servers so it didn't even occur to me to check.  So that's why the migrated VM wouldn't boot.  When I recreated the VM manually and pointed
    to the VHD file it obviously didn't include the AVHD content so it booted the server into a 2 month old state.  That led to the domain problems since the AD server account password had changed sometime in the last 2 months.  I tried a bunch of fixes
    but the only thing that finally worked was to remove the server from the domain and re-join.  Of course, that then broke Citrix, but that's getting off-topic.
    The second VM that failed was because for some reason a CSV that it relied on was not migrated over and I didn't notice that in that in the report.  And then I couldn't find any way to bring that CSV in after the fact.  I re-ran the pre-migration
    and it still didn't show it.  Of course this is my biggest volume at 800GB.  So I then re-mapped one of my old cluster nodes back to the LUN (after removing the new node), brought up the lost CSV, copied the VHD file on it to external media, brought
    the old cluster down again, the new one up and was going to blow away that LUN and create it as a new CSV on the new cluster.  Of course, when I went to go create the CSV it showed my LUN available for storage and I just had to add it and all the data
    was brought with it.  So 2 hours of copying for nothing!  I'm not at all sure what happened with this problem, but it seems either rebooting the old cluster node or the new one jarred things lose.
    Just wanted to report back saying everything is going again.  And also to vent about how poor and riddled with pitfalls this migration is.  The snapshot issue is ridiculous, how hard would it be for the tool to check for that and then throw an
    error in the migration report?
    For anyone that needs to upgrade from 2008 to 2012, good luck!

  • Hyper-v core physical harddisk

    I am running a Hyper-v core 2012 server and I want to add 2 physical disks to a VM. These will be setup in raid1 after they have been connecting.
    I have done some research but it is difficult to find information about this related to the "core" version, and lots about the GUI way in server 2012.
    Are these steps correct:
    - Offline the disks using diskpart (They are new disks I will get today)
    - Add an SCSI controller
    - Add both disks to the SCSI controller
    Do I miss a step somewhere?
    I appreciate any help.

  • Hyper-V 2012 R2 Cluster Creation Fails

    I am trying to create a 2 Node Hyper-v 2012 R2 Cluster.  The Cluster Validation passes with no errors or warnings but the the cluster creation fails. 
    The error is similar to
    here . 
    In this case he solved it by joining the Nodes to a Windows 2012 Domain.  We don't have that option in  our environment. 
    In the System Logs Events 7024 The cluster service terminated... The cluster join operation failed,  and 7031 Cluster Services Terminated unexpectedly. 
    Anyone have an idea?
    Todd

    Hi Todd,
    For troubleshooting , please try to create a new OU then move cluster nodes computer to that new OU then block inheritance , restart the nodes .
    After this try to use domain admin account logon the cluster nodes to build cluster again .

    I would also look strongly at no antivirus as well, but if you do, here are the recommended exclusions and possible issues with Anti-Virus to look out for.
    Look for the Hyper-V section:
    http://social.technet.microsoft.com/wiki/contents/articles/953.microsoft-anti-virus-exclusion-list.aspx
    Big things to stay away from from a VM level too:
    1. Do not have a set time when all VMs will kick off a scheduled full disk scan.  This can create an I/O storm on your hosts as well as saturate the CPUs as well.   Look for products or settings that allow for randomization of full disk scans on
    the VMs or do not do full disk scans and only keep the real time scanners active on the VMs for incoming writes.
    2.  Watch for Antivirus products that update all the VMs at the same time.  Again, sometimes you can randomize or exclude a scheduled full disk scan, but sometimes an automated update that kicks off say at 12am can then automatically kick off a
    mini scan.   This can also create disk I/O and CPU storms.
    The problem that still exists with many Antivirus products today is that they try to scan as fast as they can and then get out of the way.  This works ok for endpoint desktops or laptops, but when you have 50 or more VMs on a host all ramping up trying
    to get done as quick as they can, then this can cause some issues.

  • Cisco Expressway Core & Edge Cluster, or Disaster Recovery Setup

    Hi All,
    Dear experts,
    I have two sites HQ & Branch.below are my questions for Expressway Core & Edge Cluster
    1. Can i create one cluster for 6 sever for  Expressway Core and distribute 3 server in HQ &  3 server in Branch for HA
    2. Can i create one cluster for 6 sever for  Expressway Edge and distribute 3 server in HQ & 3 server in Branch for HA
    3. How would be the DNS SRV records and call flow work if the main site  Expressway Edge goes down in HQ. How the Branch Side Expressway Edge becomes active for B2B calls.
    4. What is the best design to have disaster recovery for Expressway core and Expressway Edge between Sites(HQ & Branch)
    Regards,
    Irf

    Regarding 1 and 2, as long as the round trip delay is no more than 30ms maximum, you should be fine.  I presume the HQ Branch offices for the Expressway-Core have a shared internal network, since the Core goes inside the corporate network, while the Edge goes in the DMZ or outside the network for public access.
    For 3, as long as you have your SRV records setup correct, you can set the priority of which office gets used first, and then second, in case of a failure.
    I don't have an answer for 4 unfortunately.

  • Hyper-V core 2012 R2 - Unmanageable

    Hi everybody,
    Got a fun one, kinda. So started to upgrade from hyper-v 2012 core 2012 to R2. Migrated the VMs. Formatted the system drive. Reinstalled from scratch. Added to the domain. Rebooted.
    I could remote desktop, connect with Hyper-V manager.
    Connected back to the hyper-v 2012 R2 core with RD, installed iSCSI and set the target, installed and configured MPIO. Rebooted.
    And I lost access from every where to the Hyper-V Core. The only way I can access them is via remote powershell sessions. Server manager does not work, I can't ping anymore, can't RD to them, can't SNMP either. They are in the same OU as the other servers
    still running 2012 normal.
    Any idea why, after the second reboot most access went down the drain ?
    I feel like the system thinks it is not on a domain network anymore and thus the firewall started. But even stopping the firewall did not help for one of the 2 servers. And I d rather not disable the FW anyway. I also tried hvremote, no luck.
    Regards,

    Hi,
    I am using the same plan for the MAC as for the IP. The last 3 octets of the MAC are the same as the last 3 octets of the IP. That is for the VM.
    The thing is, every time I install Hyper 2012 R2, create a LBFO team, add the management adapter, that management adapter always get 00-15-5d-00-00-00. And I install from CD. If I remove it and recreate it, same thing, still get 00-00-00. I just think it
    is painful the way the hosts are setup in Hyper-V. I come from VMWare world where a virtual switch can have multiple adapters and hold multiple VLAN. In Hyper-V you have to create the aggregate to support the virtual switch. I also never had MAC issues in
    VMWare and I keep getting them in Hyper-V be it on hosts or VMs.
    But then I am using the free tools available at the moment. Maybe VMM would work better but we can't pay that. If we were to go for paying solution, VMWare essentials would work better for us. We are kind of right between big enough to need the tools but
    not big enough that they are truly worth it. At least the Microsoft ones.
    Anyway, going back to my original issue:
    * 2012 R2 does not work with domain firewall on, even when I add the following rules:
    Enable-NetFirewallRule -name RVM-RPCSS-In-TCP,RVM-VDSLDR-In-TCP,RVM-VDS-In-TCP
    Enable-NetFirewallRule -DisplayGroup “Windows Remote Management”
    Enable-NetFirewallRule -DisplayGroup “Remote Event Log Management”
    netsh advfirewall firewall set rule group="Windows Management Instrumentation (WMI)" new enable=yes
    netsh advfirewall firewall set rule group="Remote Volume Management" new enable=yes
    The remote desktop is set via GPO at domain level and it works perfectly fine for all except Hyper-V 2012 R2 core. And the VMs are running 2012 R2 standard / datacenter.
    The Hyper-V core 2012 hosts work perfectly fine. Am I missing something specific to Hyper-V core 2012 R2 ?
    Have a fun week :)

  • Hyper V hosts with Cluster Shared Volume do not provide Shared VHDX ability

    Hi there, i've configured a pair of Hyper V hosts (UCS B230 M2) with SAN-Boot and access to a Shared Fiber Channel LUN.
    No matter what I try, when I add a SCSI Adapter and one VHDX virtual disk to a VM, the option for "Advanced" never shows up therefore I can not share the VHDX file between another VM, which prevents any VM based clustering from working (IE: Clustered
    SQL server)
    Here are the settings I have configured:
    The LUN has been formatted with NTFS
    The Hyper V hosts have been configured as a Windows Cluster with an IP address and the Fiber Channel LUN configured as a Cluster Shared Volume
    I follows the guides below
    Create a CSV
    https://technet.microsoft.com/en-us/library/dn265980.aspx
    Create a shared VHDX
    https://technet.microsoft.com/en-us/library/dn282283.aspx
    Further details:
    Two HyperV server core hosts built
    Both joined to AD
    Both joined to a Windows failover cluster
    One 2TB Fibre Channel LUN presented from an EMC VNX array to both hosts
    LUN formatted as NTFS
    LUN created as a Cluster Shared Volume
    Cluster Shared Volume present on both HyperV hosts
    VM created within the Cluster Shared Volume
    VM Booted up and Windows 2012 has been installed
    VM gracefully shut down
    Through the HyperV Manager, going in to VM settings,create a SCSI adapter, create a new VHDX file inside the CSV, the “Advanced” option for the VHDX is not present, therefore the option to make the VHDX file shared is not available
    I have followed all steps in the Microsft Technet pages to create a CSV and a VM with Shared VHDX
    I’ve cleared all settings and restarted multiple times, but this option is not present

    Hi Sir,
    >>No matter what I try, when I add a SCSI Adapter and one VHDX virtual disk to a VM, the option for "Advanced" never shows up therefore I can not share the VHDX file between another VM
    >>Yes we are using Hyper-V Server 2012 R2
    As we know Hyper-v server 2012R2 is a free version without GUI , I'm afraid you are not using Win 8.1 or other windows server 2012R2 to manage that free version hyper-v server .
    Shared vhdx is a new feature came with 2012R2 , if use previous windows to manage 2012R2 you will not see "advanced" option (The blue circle belongs 2012 , the red circle belongs to 2012R2 ):

  • Exchange 2013 MBX in DAG along with Hyper-V and Failover Cluster

    Hi Guys! I've tried to find out an answer of my question or some kind of solution, but with no luck that's why I am writing here. The case is as follows. I have two powerful server boxes and iSCSI storage and I have to design high availability
    solution, which includes SCOM 2012, SC DPM 2012 and exchange 2013 (two CAS+HUB servers and two MBX servers).
    Let me tell you how I plan to do that and you will correct me if proposed solution is wrong.
    1. On both hosts - add Hyper-V role.
    2. On both hosts - add failover clustering role.
    3. Create 2 VMs through failover cluster manager, VMs will be stored on a iSCSI LUN, the first one VM for SCOM 2012 and the second one for SCDPM 2012. Both VMs will be added as failover resource.
    4. Create 4 VMs - 2 for CAS+HUB role and 2 for MBX role, VMs will be stored on a iSCSI LUN as well.
    5. Create a DAG within the two MBX servers.
    In general, that's all. What I wonder is whether I can use failover clustering to acheive High Availability for 2 VMs and at the same time to create DAG between MBX-servers and NLB between CAS-servers?
    Excuse me for this question, but I am not proficient in this matter.

    Hi,
    As far as I know, it’s supported to create DAG for mailbox server installed in hyper-v server.
    And since load balance has been changed for CAS 2013, it is more worth with DNS round robin instead of NLB. However, you can use NLB in Exchange 2013.
    For more information, you can refer to the following article:
    http://technet.microsoft.com/en-us/library/jj898588(v=exchg.150).aspx

  • Hyper-V 2012 R2 Cluster - Drain Roles / Fail Roles Back

    Hi all,
    In the past when I've needed to apply windows updates to my 3 Hyper-V cluster nodes I used to make a note of which VM's were running on each node, then I'd live migrate them to one of the other cluster nodes before pausing the node I need to work on and
    carry out the updates, once I finished installing the updates I'd then simply resume the node and live migrate the VM's back to their original node.
    Having recently upgraded my nodes to Windows 2012 R2 I decided to use the new functionality in Failover Cluster Manager where you can pause & drain a node of its roles, perform the updates/maintenance, and then resume & fail roles back to the node,
    unfortunately this didn't go as smoothly as I'd hoped, for some reason it seems like the drain/fail back decided to be cumulative rather than one off jobs per-node ... hard to explain, hopefully the following will be clear enough if the formatting survives:
    1. Beginning State:
    Hyper1     Hyper2     Hyper3
    VM01        VM04       VM07
    VM02        VM05       VM08
    VM03        VM06       VM09
    2. Drain Hyper1:
    Hyper1     Hyper2     Hyper3
                    VM04       VM01
                    VM05       VM02
                    VM06       VM03
                                   VM07
                                   VM08
                                   VM09
    3. Fail Roles Back:
    Hyper1     Hyper2     Hyper3
    VM01        VM04       VM07
    VM02        VM05       VM08
    VM03        VM06       VM09
    4. Drain Hyper2:
    Hyper1     Hyper2     Hyper3
    VM01                       VM04
    VM02                       VM05
    VM03                       VM06
                                   VM07
                                   VM08
                                   VM09
    5. Fail Roles Back:
    Hyper1     Hyper2     Hyper3
                    VM01       VM07
                    VM02       VM08
                    VM03       VM09
                    VM04  
                    VM05
                    VM06
    6. Manually Live Migrate VM's back to correct location:
    Hyper1     Hyper2     Hyper3
    VM01        VM04       VM07
    VM02        VM05       VM08
    VM03        VM06       VM09
    7. Drain Hyper3:
    Hyper1     Hyper2     Hyper3
    VM01        VM04
    VM02        VM05
    VM03        VM06
                    VM07
                    VM08
                    VM09
    8. Fail Roles Back:
    Hyper1     Hyper2     Hyper3
                                   VM01
                                   VM02
                                   VM03
                                   VM04
                                   VM05
                                   VM06
                                   VM07
                                   VM08
                                   VM09
    9. Manually Live Migrate VM's back to correct location:
    Hyper1     Hyper2     Hyper3
    VM01        VM04       VM07
    VM02        VM05       VM08
    VM03        VM06       VM09
    Step 8 was a rather hairy moment, although I was pleased to see my cluster hardware capacity planning rubber stamped, good to know that if I were ever to loose 2 out of 3 nodes everything would keep ticking over!
    So, I'm back to the old ways of doing things for now, has anyone else experienced this strange behaviour?
    Thanks in advance,
    Ben

  • Hyper-V 2008 R2 cluster down

    Hello,
    We have a 3 node Hyper-V 2008 R2 failover cluster. Yesterday we had problems and all VM's on node 3 went down. At 17:00 the back-up starts of the VM's which are on CSV(with DPM 2010 and hardware providers for Dell) but then one nodes crashed. It look like
    node 3 tries to take CSV04 ownership but node 1 doesn't accept that. See the cluster log below. Can someone tell me what triggered this? And how to fix this? Many thanks!
    It start with a message that some Volume manager disk group and Geocluster disks are not found. This says nothing to me.

    Hi,
    Unfortunately, the available information is not enough to have a clear view of the occurred behavior, from the cluster perspective.
    Network activity could be related to our scenario too, although it is difficult to identify the specific cause. Maybe you can try reconnect the node 3 storage connective.Could
    you offer us more information such as the failover cluster validation error, the failover cluster log original error log.
    Regards.

  • Unable to connect copied vhd files to VM Hyper-v high availability cluster.

    Hi
    I have my VMs VHD files stored on my SAN  and I have a copied one of the LUNs containing a vhd file which I have then exported to the shared storage of the hyper-V cluster which is just like and other VHD. The problem comes when trying to connect this
    copied vhd to the VM which still uses the original VHD . The system refuses reporting that it cannot add the same disk twice.. 
    These are two different VHD files
    I have: renamed the new file, changed the disk ID, changed the volume id and using vbox (because it was the only way I could find do it ) changed the uuid of the vhd file.  But still no joy.
    I can connect the volume to any other VM without any issues, but I need to be able to connect it to the same VM..
    I'm not sure how  Hyper-v is comparing the two VHD files but I need to know so I can I can connect the copy VHD without having to copy all its contents to a new VHD which is impractical..
    Anyone got any ideas or a procedure??
    windows 2008 R2 cluster with 3par SAN as storage.
    Peter

    Hi perter,
    Please try to refer to the following items :
    1. create a folder  in the LUN , then copy the problematic VHD into it ,attach the copied VHD to original VM.
    2. copy the problematic VHD file to another volume ,then attach it to original VM again .
    Best Regards

  • Hyper-V - 2 node cluster goes down if one server shutsdown

    Hi all,
    I built a 2 node cluster with tiered storage and then I started doing some tests:
    * Drain one node and all the VMs moved to the other node, perfect
    * shutdown the drained node.
    The entire cluster crashed!!! The remaining node is trying to re-connect to the iSCSI SAN without success.
    * I booted the drained node. And it would not re-connect to the iSCSI SAN either. I had to force the reconnect in the iscsi control panel to make it re connect.
    So why would shutting down one node kill the cluster ? Sure it was the node that had the tiered pool online, but even then, isn't failover cluster supposed to put that one back and working on the other node ?
    Why did the active node lose the iSCSI connection too ? It had VMs running on it prior to the shutdown of the other node. My DC that was running on that other node is also now un available, can't ping it or anything.
    So what did I miss in the configuration of the cluster ? I followed the msdn 2 node hyper-v cluster doc.
    I am really worried atm since I had over the past 3 months a ton of issues with hyper-v going from using tiered storage, shutting down nodes, MAC address on the VMs and the hosts,... I thought that after hyper-v 2008, Microsoft had really made some progress
    with Hyper-V but I truly regret not going with VMWare again this time around.
    That cluster was supposed to go into homologation phase tomorrow at the datacenter but now I am unsure if I ll ever be able to trust it to work.
    The SAN is an MD3200i which is reported as Hyper-V ready.
    Any hint on where I have gone wrong would be appreciated.
    Regards,
    Edit: even from the host with powershell I was not able to shutdown the DC and reboot it clean. Said the integration services were not reachable... it is a 2012 R2 servers...
    Edit2: One of my VM is gone ! Can't even find the file on the disks either locally on the hosts or on the SAN. WTF!!!

    Actually comes across very reasonable. And I think you are right. I tend to compare Hyper-V to vSphere with vCenter included. I have not seen nor used VMM. Also true that Storage Pools and iSCSI is not Hyper-V, but to me it comes as a package just as much
    as ESXi 'comes' with it.
    As for burning personnal hours and money on books, I have, just as much as I go to conferences when I can and can afford it. And the only thing I would envy you, is the fact you have your colleagues to bounce idea of / lay on if necessary.
    As for the few hundred box for the management suite. I believe the stack you speak of would actually cost my current company about 14k$, that is not a few hundred box. That is pretty much the cost of one of the 2 SANs.  By 14k$, I mean that
    we have 6 servers with 2 sockets each, running a lot of VMs, which means Datacenter licences which list price is 3.6k$. I am not even including the CALs. Or am I mistaken on the licensing ?
    If VMWare, I would be going with essentials which, at the same server perimeter, would be 30% less expensive. We don't really need the full blown one at our level.
    I am also locked by hardware that was ordered by my predecessor which do not provide the service we need them for. (I blame the vendor on that one, my predecessor was not an infrastructure guy). As for storage, if you are referring to SMB3 and using
    a failover cluster to provide the disks to the hyper-v hosts, I agree. I am just not too sure on the technology yet and went more for safety until I can test it thoroughly in the dev environment.
    I also hope Microsoft will add an easier way to set the media type on disks as well as allow for more than just SSD and HDD or even allow us to define our own.
    I actually fooled the system this time around because SSD are too expensive and too high a failure rate compared to 15kRPM (yes the performance are lovely) at the moment. So I made the 15kRPMs into SSD.
    For the remote management issue, i meant that actually, at this time, I have to disable the domain firewall to be able to manage the hyper-v 2012 R2. I tried hvremote, adding all the necessary rules, etc... What I did for 2012 worked perfectly fine and I
    had full controls. 2012 R2 does not. I have another thread on this in the forum and I ll come back to it as soon as I can.
    I don't really care for the no interface thingy, I enjoy Powershell and scripting fine :) Does a lot of automation for me :) I am used to scripting anyway and it is faster to reproduce steps that way. You do it once, and you got something you can apply with
    little changes to everything.
    I joined the company in November last year and I got dropped a full stack to upgrade in 6 months while maintaining the current one. Encountering the problem now is better and is, fundamentally, good, though it is time consumming.
    By full stack I mean:
    * Help the dev re-design the apps so it handles load better. Get out of Windows 2003 and migrate to 2012 and validate all the applications on 2012 as well as improve security.
    * Implementing a monitoring system for the infrastructure and the applications.
    * Upgrade SQL Server 2005 to, in this case 2012 Standard (no choice and enterprise not in the price range of the company). Converge our current test and prod environments. Optimize all the queries... And naturally validate the applications.
    * Upgrade the certificate authorities so they are available on all sites. Haven't scratched that one yet.
    * Design a fully site redundant architecture so that if a site goes dark we have no impact. If there is partial failure on one site, no issue either, and so on XD. I wish I had AG :)
    * Implement a single windows domain on all the sites, that will be a relief :) Running 4 domains and about 10 different workgroups atm
    * Upgrade the firewalls, switches, servers hardware, ... Implement the necessary networks for virtualization and improved security rules... (Don't buy SonicWalls, had a worse headache with them than Hyper-V :) )
    * Migrate the users from old domain to new one. Windows 8 does not have the user migration tool anymore :(
    * Plan the DR tests and processes :)
    * Gotta get Hyper-V replica working as well as backups.
    * And naturally make all the documentation so that if I happen to get under a bus, anyone in the company can just follow the documentation in case of an emergency.
    And I am sure I am still missing some part of the environment no one knows about at some places :) Found a new network today XD.
    As for the mixed VM management, I mean some that are in HA on the cluster and others that don't need and must not failover. Am sure there is a way to configure them in the failover cluster so they don't failover. I just need to spend the 15 minutes looking
    into it :)
    Since I have had that SAN, I spent about 5 days on the phone with Dell support. That iSCSI issue is not the first one I got :( But in the production environment, that issue has disappeared. So at this time, i have switched working on other issues. And with
    the information you provided, I'll be able to know if one of the node of the cluster lose the connectivity which will help avoid this issue in the future.
    And it is a very good and interesting challenge. I am just running in way to many issues doing a 10 year old system upgrade :) I was expecting to have an easier time with Microsoft Virtualization than I've had.
    Oh and just for the fun, I also had VM disappear, no more file, no nothing, just poof. Have not figured how that happened yet. Had the backup so not much of an issue, but still, it went poof when the original issue happened.
    Thanks for the time and the tips :)
