OVM support for NPIV and pass through disks

Hi Gurus,
I have a couple of questions -
1) Does OVM support NPIV?
2) Does mapping the physical disks via the phy: definition in the vm.cfg file equivalent of pass through disks to the guest OS?.
thanks!

Thanks!. The pass through question was actually in context of usage with snap* products from netapp as they work with VMware. All the snap* work with RDM's in VM's (pass through's), so i was wondering if the snap* could be made to work with the phy: def to the VM's as well. The RDM def should be equivalent of the phy: def ..right?. So ideally, they ought to work?No idea, to be honest -- I haven't worked with NetApp gear yet. You're probably better off checking with NetApp directly as well.

  • Need help on Hyper V 2012 for configuring pass through disks

    Hallo guys,
    I have 7 hypervisors of Windows server 2012 running on bare metal, all are in cluster. I also configured SCVMM 2012 server.I created 10 Vm's. Now i want to make clusters of 2 node each & assign LUNs to my VM.
    Storage guys have assigned all the LUNs to my physical servers, when i go to disk management of my physical servers , i see all LUNs are offline state(by default..)
    My question is how do i assign the LUN to my VM? what is the steps for this ? i also wil be making 2 node cluster of VM's.
    Regards,
    Amol Sutar

    Hi Amol,
    >>i see all LUNs are offline state(by default..)
    It's normal. To ensure the Guest has exclusive access to the storage, the LUNs must be placed in an
    Offline state from the Hyper-V server perspective.
    >>My question is how do i assign the LUN to my VM? what is the steps for this ? i also wil be making 2 node cluster of VM's.

  • Should I Install SQL Server 2008 R2 on a VHDX or Pass-through disk

    Hi,
    I am in going to be setting a virtual server running Windows Server 2008 R2 on my Hyper-V cluster and I will be also adding SQL Server 2008 R2 once the OS is configured. Can you please suggest whether I should setup a VHDX or a pass-through disk? I have
    read articles online suggesting to use a pass-through disk from my SAN but I also read that since Windows Server 2012, VHDX is as good as a pass-through disk, especially because it will allow to have snapshots taken, unlike the pass-through which will not.
    Please advise on whether I should chose a pass-through disk or a VHDX.
    Thanks in advance,

    Hi Aquila,
    There are three basic types of Virtual Hard Disks (VHDs) that you can use with VMs, such as dynamic VHD, fixed VHD, and differencing disks. Usually, the fixed VHD is almost always the best choice for virtualized SQL Server systems that run a production workload.
    You can use dynamic disks for noncritical production workloads, as well as for testing, training, and lab environments. Pass-through disks offer the highest level of performance for VM storage, however, Pass-through disks can't be moved without incurring downtime,
    and they don't support VM snapshots. For more information, see：http://sqlmag.com/sql-server/sql-server-virtualization-tips
    In addition, there is an article about how to setup boot from VHD for a SQL Server. You can review the following link.

  • Cannot clear "Current read-only" on pass through disk

    This is not the end of the world, but it's very annoying so I'm hoping somebody can explain what's going on or perhaps suggest some additional troubleshooting.
    Here's the scenario: Server 2012 Core VM  with the file services role installed and running as a role on a Server 2012 Hyper-V failover cluster. IDE 0 is a standard VHDX in clustered storage. There are 2 pass through disks on SCSI targets 1 and 2. I
    proceed to attempt to add a 3rd pass-through disk:
    1. Create a 750GB LUN
    2. Mask the LUN to the cluster
    3. Online the new disk on a cluster node
    4. Initialize the disk on the node
    5. Offline the disk
    6. Using Failover manager, add the disk as new Available Storage in the cluster
    7. Using Failover manager to modify the file server VM's settings, add the new storage to SCSI target 3
    8. Using diskpart on the VM, clear the readonly flag from the disk
    At this point, I was able to create a partition on the disk using new-partition with the -usemaximumsize flag, but I was unable to format it. It turns out the new partition size was 0 bytes. So I went back into diskpart and lo and behold, although the readonly
    flag is cleared, the "Current readonly status" on the disk is still yes.
    To test the issue, I offlined the disk in the VM, removed it from the virtual SCSI chain, removed it from cluster storage and then onlined it in the owner node. I was able to partition it, format it and create an empty folder, so it is not flagged readonly
    at the host or SAN.
    So I offlined it on the node and added it back to cluster available storage and then added it back to SCSI target 3 on the VM.
    Again, I removed the readonly flag from the disk and again it cleared but the disks "current" status remained "Yes" and I was unable to manipulate the disk.
    Stop/start vds did nothing and as this is a production server I could not restart it midday.
    So I offlined the disk in the VM and removed it from SCSI target 3, then added it to SCSI target 4. This time, when I online it in the VM and use diskpart to clear readonly, both readonly and "current" readonly clear just fine and now the pass-through
    disk is operating as expected alongside the other 2 pass-through disks on the server.
    Any ideas what went wrong in all this or how I can clear SCSI target 3 for another disk without having to restart the VM?

    Hi,
    If the disk that you want to add appears in Disk Management but does not appear after you click Add a disk, confirm that the disk is configured as a basic disk, not a dynamic
    disk. Only basic disks can be used in a failover cluster.

  • CSV V/s Pass through disks with HV 2012 R2 failover cluster

    "The juice isn't worth the squeeze" (c) ...
    Tim is 200% correct here: any performance gains (if any...) you'll get will fade in darkness compared to management burden you'll have with pass-thru disks (issues with failover, VM migration and no
    real support with a major VM backup vendors). Making long story short: don't do it.

  • Reading hyper-v pass-through disks using WMI?

    How do I read pass-through disks for a guest VM from a Hyper-V using WMI? I'd like to read the pass-through disks that are available to a guest VM using the below mentioned ways:
    1. Add a disk to Hyper-V server, take it offline and assign it as a physical disk to VM
    2. Configure iSCSI initiator in guest VM to get a disk directly from storage array
    3. Use VFC to export a fiber channel lun to guest VM directly.
    Thanks/Hem

    You had another post with very similar questions, and I replied to it.  A broad answer is to use PowerShell as it does most, if not all, of the WMI work for you.  If you are having issues, it would be helpful for you to post specific questions
    about the issues you are seeing.  If they are scripting questions, you would reach more scripting experts in the Scripting Guys forum (http://social.technet.microsoft.com/Forums/scriptcenter/en-US/home?forum=ITCG). 
    And you can go to the scripting gallery (http://gallery.technet.microsoft.com/) to find examples of many, many different things.

  • ZAM support for Debian and CentOS

    I'm planning to install Zenworks Asset Management and I would like to know if it would release a support for Debian and CentOS. We have a heterogenous network environment and there are servers that are running Debian and CentOS. Is it possible for ZAM to release a support for these operating systems?

  • Feature Request: Support for .idea and .psdx extensions

    I've noticed that Adobe Bridge does not have any support for .idea and .psdx files.  The .idea files will show a idea file icon but the .psdx will be a blank, unknown file icon.  Both do not show any preview in Bridge.  I do not know why this is as previews for these files can be seen when they are uploaded to creative cloud or the new creative cloud mobile app.

    Hi,
    I've logged an enhancement request on this.

  • Just purchased photoshop cs6 for windows and received installation disk.

    Just purchased photoshop cs6 for windows and received installation disk.  Where do you find the serial number on the disk?  What should the serial number start with?  The disk was in the original box and I see a number that start with 910.....
    The box was in a brown envelope and there is barcode sticker on the back with more numbers.  Where should I look for the actual serial number.

    No, we have consolidated on the Apache XML/XSL stuff. You are free to use

    I think you're a little confused about what "Open Source" means. Itdoesn't mean "unsupported." If you want support then you need to pay forit,
    just like any software. One of the advantages of open source software is
    that you aren't tied to a single vendor for your support - anyone with the
    appropriate skills can take the source code and
    provide support, as BEA have chosen to do in this case.

  • Maximum Nodes supported for NLB and Cluster in Windows Server 2008 Standard Edition ?

    Hi.
    I am looking for information How many nodes supported for NLB and Cluster in Windows Server 2008 Standard Edition ?
    If you can provide for all the versions that would be great.
    -Thanks
    - Ajay Chanana

    Hi,
    You can configure a Windows server 2008 NLB cluster with up to 32 nodes. However,
    scaling beyond 8 nodes will cause a slight performance hit because the network traffic is broadcasted to every node and only one NLB node accepts the connection.

  • Firewall Rules for Printing and Scanning through Windows Firewall

    Hello,
    I am having trouble determining the Ports, Programs, and Services required for printing and scanning with my AIO.
    I am using Windows Firewall in Windows 7, and am only allowing certain rules in and out.
    I know the firewall is the problem, for when I disable it, everything works fine.
    Which rules are required for printing and scanning through the firewall?

    4th Bump,
    Is there anyone who can help me with this?
    As I said before, other printer manufacturers such as Lexmark and Brother provide this exact information.
    Why doesn't hp have a document for this? Does everyone just disable their firewall or open every port?
