The Group PS6100XS and Hyper-V Server 2012: migration of storage between LUNS corrupts VM

Well, I'm puzzled! Summer hit my head against this whole week. Basically, ranging from a virtual machine clustered LUN on the Bay EqualLogic corrupts the virtual machine. Here is my configuration:

  1. SAN 1: PS6100XS 6.0.1 firmware, 2 LUNS configured as CSV, 1 as a quorum disk
  2. SAN 2: FreeNAS 8.3.0, 2 LUN (ZFS-formatted, for what it's worth)
  3. Server 1: Dell R310 running Windows Server 2012 with Hyper-V installed feature. 4 network cards: 2 made team for traffic LAN, 2 for iSCSI with HIT KIT 4.5 configured for MPIO.
  4. Server 2: Old box SuperMicro running Windows Server 2012 with Hyper-V feature installed. 2 network cards: 1 for LAN traffic, 1 for iSCSI with HIT KIT 4.5 installed
  5. Created and all cluster validation tests passed
Here's what works:
  1. Ranging from a virtual machine of the LUN if there is no activity on the VHDX
  2. Move a VM all LUN the EqualLogic to any number of unit logic FreeNAS or vice versa
  3. Move a VM between LUNS on the FreeNAS
  4. Move a VM between LUNS on the EqualLogic BEFORE I created the cluster (just using Hyper-V Manager, not the Failover Cluster Manager)
This is what kills the VM whenever:
  1. Create a virtual machine through the Failover Cluster Manager - is not matter which node owns the storage or the VM - tried all combinations
  2. Take an active virtual machine, power and move a LUN EqualLogic to another EqualLogic LUN. The move signals the success, but the VM blue screen at the end of the move will and will no longer be able to start. It's basically fried.
BTW, I tried also to disable one of the iSCSI NIC on the R310 - what does not help either. Any ideas? I have a case goes with the support of Dell EqualLogic, but so far they have been puzzled. Anyone got something like this works yet?

OK, after Dell tried about 5 different times to tell me that my setup was not supported (actually claimed that EPA software was not supported!) I finally got someone who gave me workaround: disabling ODX by changing the key "reg" HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\FilterSupportedFeaturesMode from 0 to 1. This "fix", but it also takes one of the most interesting features of the 2012 Server + EqualLogic: ODX! With active ODX, I can move 20 GB in< 1="" sec.="" with="" it="" disabled,="" it="" takes="" around="" 2="" minutes,="" depending="" on="" network="">

  • VMware ESXi 5.1 can run Microsoft Hyper-V Server 2012 SMV also, nice!

    I created a detailed instructions (with screenshots and video) using GA-level code here:

    http://tinkertry.com/ESXi-5-1-running-hyper-v-Server-2012

    using the "basic" version of the new Hyper-V, with tips and ideas from these forums and other sites on the previous beta tests.

    Here's the gist:

    • Create a "Microsoft Windows Server 2012 (64-bit)" VM, using the default Configuration
    • Right click on the new virtual machine and material virtual upgrade to Version 9
    • twist the VMX, adding these 4 lines:

    MCE. Enable = TRUE

    Hypervisor.CPUID.v0 = FALSE
    featMask.vm.hv.capable = Min:1″ «»
    VHV.enable = TRUE

    • Remember, it is assigned to a network where the vSwitch is Promiscuous Mode to Accept
    • Turn on the new machine virtual of Hyper-V
    • perform the default installation and configure Hyper-v, hard IP-code if you wish, create an Admin user and password name that matches a customer's system
    • create a Windows 8 'customer' VM, as the Hyper-V Manager takes just a few seconds to add
    • Difficulty of COM security on the client system
    • use Hyper - V Manager this virtual machine to connect to Hyper-V, and then...
    • create a Hyper-V hosted Virtual Machine, can connect you and turn it on to test

    I'm looking forward to suggestions or alternative methods, but for the moment, it was the only way I could get it to work in my own laboratory, thought that others might not want to try to replicate this exercise.

  • New to 8.1 and wanting to run Hyper V and 'try MS server 2012 ".

    Hello

    Built a new PC and dropped in Enterprise 8.1... added Hyper v and downloaded the copy 'try' MS Server R2 2012.

    I pulled the low R2 for Windows Server 2012 on the Technet Evaluation site and got the package: 130928-2229_server_serverdatacentreeval_en-us. VIRTUAL HARD DRIVE

    I got going and he ran a few days (course worked very well, taking 70-410) then a few days later, I just clicked and deleted the instance of the virtual machine in the Hyper-V Manager because I wanted to change the config was not drives or anything else - error 1

    Tried to re - install again and, of course, no joy, tried a few things and vain for 2 days, now this morning spent half a day, re-installation of 8.1 again to try to get the D/L will again... I see little thing Assistant account of that 8.1 restored my profile so maybe that's why the Hyper V ALWAYS failed to load the virtual hard disk.      Just a guess...  Error 2?

    Back in the new Hyper-V install this morning in the reinstalled 8.1 and STILL get the error when I try again:

    -Open the Manager Hyper of V

    -Machine virtual acts-Import

    -Dialog wizard - following

    -Locate the folder - new folder on the hard disk

    -Put in the path = C:\ HyperV files (there is a copy of 130928-2229. *.) Disk virtual hard in the folder)

    -Then click on select file-

    S ' poster in the path = C:\ HyperV can - next

    -Get the Assistant barf:

    Hyper-V not found of VMS to import from location "C:\HyperV Files\".

    The file "C:\ HyperV Virtual Machines\' is not found.  You might not have permission to access.

    So, it is always throwing the error because I crashed two days when I deleted the original installation of work I guess.

    Then it's because I've used the file 'try' once and I pooched when even I have re-installed 8.1?  Or is it a combo of 8.1

    Assistant to put something in the drive?  Or can I go back and re - define something from the test site, or what?

    I have now lost 3 days fart around this problem... am I pooched?   I do not have a complete MSDN Dev account so that I could

    probably manually install a copy of the R2 2012 legit keys into a new virtual machine on PC, but y at - it another way

    for the evaluation copy go even faster!

    Cheers

  • How to activate the Hyper-V Server 2012 on Fusion 5?

    Dear members of the Forum,

    I have a Mac Pro early 2008 Intel Xeon, 16 GB under Snow Leopard and VMWare Fusion 5 installed, as well as a few virtual machines running perfectly. I decided to create a virtual computer that is running Windows Server 2012. The installation went well. However, when I tried to activate the Hyper-V technology I got in trouble.

    In the Virtual Machine settings > system settings > general: I chose "Hyper-V (not supported).

    In the processor and memory, I selected 4 cores, 4 GB and in advanced: enable applications to hypervisor...

    In other/advanced: the virtualization engine preferred: Intel VT - x with EFA

    and all the possible permutations of these selections. Nothing has worked.

    Error messages:

    Hyper-V cannot be installed. The processor has no virtualization required capabilities.

    Virtualized Intel VT-x/EPT is not supported on this platform.

    Preferred mode is unavailable. Using VT - x instead. This host does not support EFA.

    All this leads me to believe that my hardware configuration does not support the operation of computers virtual hyper-v in Fusion. According to your philosophy, we can consider this to be a reality: everything is always possible. However, what drives me nuts are guys on internet blogs, everybody saying he's working on their system! I would like to hear an authoritative voice if possible, or not.

    Thanks in advance

    Hi Eric and welcome on VMware communities!

    It is purely a matter of features of the CPU.  None of the processors that apple delivered in Early 2008 Mac Pro systems supports Extended Page Tables (EPT).  According to the list of the Mac Pro systems, the processor that you have will be E5462, E5472 or X 5482, as well as relevant on the (related) Intel Web site pages show no support for EFA everymac.com.

    Without EFA, we cannot virtualize VT - x.  In other words, the guest operating system cannot see and use virtualization assisted by material, although the merger itself will be able to make use of the hardware support of the functions of virtualization host to run the virtual machine: we can use VT - x, but cannot virtualize to make it available to a nested prompt.

    Hyper-V is entirely dependent on the hardware support for virtualization (VT - x for example), then it won't work as a guest nested in your configuration.

    Companions VMwarian jmattson produced a great entry on nested VMS requirements and functional combinations here: nested VMs running

  • How to update the model of RDS for Windows Server 2012 collection?

    Hi team,

    I want to know how to update the collection of RDS model (model master sysprep) which is used to create the collection?

    I tried the below way but did not get the update of the collection of virtual machines.

    -Start the image of mater of sysprep

    -install the required components

    -resysprep the image and stop it

    -East went to the RDS Collection and added new virtual machines in collection (removed the old his)

    Once created, I opened a session in the machines, but I don't see the updates (I installed some software in the sysprep image however and no is not there in the virtual machines in the pool)

    Can someone let me know if I need to create a whole collection again or the way I do it is a proper way? If it's a good way what could be the reason why I get the new installed software model sysprep image in virtual machines created in the pool, based on the model?

    How do we actually updated for security and other regular patches updated in virtual machines? In my view, we use the same approach?

    Any suggestions will be appreciated.

Read well the hardware specification: http://h18001.www1.hp.com/products/quickspecs/14208_na/14208_na.pdf I see that he has taken a TPM installed on the blade, but I don't know how to make sure that it is activated or used by the Virtual Machine?

    Any kind of help would be greatly appreciated.

    Thanks in advance

    I had a few goes at it and it's not like you can virtualize a TPM. It would make sense if it was the case - the secure TPM was not designed to manage multiple instances of the OS.

    I ended up making USB passthrough on a USB stick and have the Bitlocker key stored on this stick as a demo. Certainly not a transaction supported, but it showed that the storage of key seems to be the only issue.

  • Why the continuous measurement and Logging in LabVIEW 2012 Project uses strings instead of Enums and orders from the queue?

    Hello!

    I noticed that the continuous measurement and a project in LabVIEW 2012 Logging using chains instead of enums and orders from the queue. I wonder if there is a good reason for it?

    Kind regards

    Anguel

    First, string vs enum debate is probably the version of LabVIEW vim vs emacs. There are good arguments on both sides, and I doubt that there is always a "winner".

    A brief summary of our reasoning for the current state of the project examples:

    1. We used enums for the state machine because it is self-contained. A state machine will never tell himself to enter a State, he does not know. Knowing (as the programmer) all possible States with the help of an enum allows you to enlist the compiler in order to help us avoid mistakes to change the time (because you can't quite out an enum and LabVIEW can be said if you are not covering all cases to a structure of the case, etc..).

      Enums provide greater protection and rigidity by ensuring all withdrew at the time of publishing. This is often the 'default' recommendation that we do.

    2. We used strings for messages in queue manager because the producer of message and the message handler could be independent processes that are reused or traded. Channels avoid the need for the compiler to be able to connect the orders and push this responsibility to the programmer. This allows you to develop some sub-components independently as long as you agree to a series of channel commands that you can manage - you need not to share a file 'messages.ctl' or 'states.ctl '. It is conceivable a loop of message management a message it does not, how you can decide to either silently ignore it or will trigger an error (as we do in the model). The strings make it also easier if you want to swap the queues of LabVIEW outside by a TCP implementation for network vacilitate or intra-Processuse communication where the other end may or may not be written in LabVIEW.

      Channels to provide more flexibility (that is, you can add new commands to an existing via plugins system, you can pass parameters as part of the string, etc.) at the expense of pushing her potential errors at run time and to put more responsibility on the programmer.

    3. The actor's gifts frame a 3rd option - using classes such as messages. For me, it combines many of the advantages of these two enumerations (strictly typed, change errors) and strings (flexible and scalable), but with the disadvantage of being somewhat less transparent (you understand OO, be comfortable to navigate through a multitude of screws, legacy of understanding, etc.).

    I don't know there are other reasons, others to the breast OR had or seen as we validated models and examples of projects in-house, but here are my reasons. We know that we can not design for each situation there - our goal is to get useful models against new users to make them aware of what well thought LabVIEW programs are similar to experienced users know their applications better and I hope they do not hesitate to change what we provide or create their own designs, when they feel it's necessary. (On a side note, please share what you come up with - a community of experts sharing models would be really useful to us all LabVIEW users).

    Best regards

  • Problem with the search service on a Windows Server 2012 R2

    Hi all

    I'm having problems setting up my newly installed Server vCenter server.

    Everything seems to be installed properly, at least I got no error message and I am able to connect to the Web Client vSphere.

    However, I can't create a data center as the inventory does not display any server...

    Weird, isn't it?

    When I try to access to the https://localhost:7444 / lookupservice page, a message tells me that the service is not available.

    Is there something else to do here?

    Something else weird to me, a beginner in VMWare environments, is that although I'm loging as administrator, it seems that I have not at all privilege. For example, for roles see, access to licenses and so on.

    How I setting a user administrator 'real '?

    Do you think that my problem might be this question of privilege? And that I do not see any server in the inventory because my administrator user does not have the appropriate rights to view it?



    Thanks in advance for any help you can provide.


    Kind regards
