Cannot add Raw Device Mapping as hard drive

• VM cloning with raw device mapped drive

  Hey people... need help.

  I have a virtual machine that lives on a 500 GB Lun. The virtual machine has a C: drive of 60 GB (OS) and a 1.5 TB Raw Device Mapped LUN.

  My problem is I'm trying to clone this machine to have a backup of it. However when I try to clone a 500 GB or even 1 TB data store it says that I don't have enough space to do. I went and removed the RDM 1.5 TB LUN in cloning options so that it would only clone the C: drive. Still the same message.

  Also I noticed that the data of 500 GB store the VM currently living has a hard 1.5 to file which I assume is the Raw Device mapped LUN. Why this creates a file if it is mapped SAN. How she even to create a file of 1.5 TB on a 500 GB data store?

  Certainly, this seems to be the reason.  Instead of a clone, use vmware converter standalone and treat the VM as a physical server.  That should allow you to continue.  If nothing else, you can 'remove' the raw device of the VM, clone and then add the raw device to the original.  Converter should work well.

• Creation of Raw Device Mapping (RDM) is not supported for local storage (1017530)

  "Often, localstorage devices do not support VPD page 0x83 and can therefore be used for Raw Device Mappings (RDMS)." The content of the page 0x83 is used as a unique identifier for the device. For more information, see creating Raw Device Mapping (RDM) is not supported for local storage (1017530). »

  Does anyone know if this is even the case for modern storage?

  We are a dell shop, wishing to take advantage of the ability to create up to 64 TB RDM.

  However, the storage of the host in question will be local SAS only.

  Prefer not to have to merge muliple 2 TB VMDK into windows to make a record of 4.5 to.

  Then projected on the presentation 1 x 4.5 CT rdm

  If you plan to use a SAS controller, you should be able to do this. Your drive will be identified as a device of the naa, and you will be able to add as an RDM to VM - only with ESXi 5 (which can support more than 2 TB LUN).

• VM 2 not clustered for a raw device mapping

  Hi, I'm new in the world of VMWare. I watch discussions related to this issue, but the only one I met was on "more than a vm in the group for access to the raw device mapping drive". In this thread, we had to change the vmfs to a shared access mode.

  My question is:

  I want to have 2 vm with the same raw disk bound, but only one of them is going to power. This virtual machine (it is power on) will work with the raw disk (data base), while the other virtual machine is turned off. In the case of the first vm failed, I disabled this virtual machine and turn on the virtual machine second. This second vm start working with the database in the raw disk. How can I do this? Is necessary how to access shared for this problem?

  I hope you understand me with my poor English.

  Thank you very much.

  What you want to do is simple, you do not need to use shared mode. Probably the best way to achieve your goal is to build your first virtual machine and get it all set up and then remove (do not remove) the RDM and the clone to the virtual machine. This will result in two virtual machines with the same host name and the same SID (assuming Windows here) - two IDENTICAL systems. Power on each virtual machine in turn (only lit at the time) and add the ROW as an existing drive. As long as one virtual machine is running at the same time, there will be no problem.

• RT: Remote desktop says "cannot find a device suitable for C drive.

  Hello

  There is a french position on exactly the same topic, but I can't apply the solution given here.

  My problem is this: I have a remote, ready to work as a target RT Office. It has been verified for compatibility, the hard drive has been formatted to FAT32, it was found by my host and received a static ip address. I installed the software, I need (LabView RT 9.0) using MAX. Now, when I try to boot with the option 'start using software installed on your hard drive', all I get is the message

  "Cannot find a device suitable for C drive.

  I have reset the BIOS, tried to format the drive hard in the other format, uninstalled and reinstalled the software, tried to start the pc target without the USB, but nothing seems to work.

  You have ideas on what goes wrong?

  Thank you

  Samuel

  Have you tried changing the settings of the BIOS for the hard disk controller?

  There could be different modes available.

• Grey raw device mapping

  We are implementing vsphere 5. our host machine is HP DL 380 G7 and storage storage IBM DS. We are implementing SAS SAN using HBA cables. There is no iSCSI or fiber module. We want to implement file on vphere server using win Server 2008 R2 SP1. We want to access our data directly from SAN LUN and not vmware data store. Whenever we try to add disks of virtual machines, raw device mapping is gray. If we check in the adapters of storage, we can see available LUNS. I don't add it to the data store. still, it is grayed out. Why? Please help us

  Welcome to the community,

  Please read http://kb.vmware.com/kb/1017704 to find out if your storage system supports the RDM and whether it's save to disable the ROW filter. Article is not tagged for ESXi 5.0, but I guess this also applies.

• Virtual Raw Device Mapping

  Can someone explain to me the difference between a regular virtual disk and a virtual raw device mapping? When I create the RDM I am just creating a file pointer to the correct virtual file? If yes why anyone would use virtual raw device instead of just mapping to create a typical virtual drive? I understand the benefits and limitations of the physical RDM I just do not understand the goal of the RDMS virtual.

  Well, even if a RDM in virtual mode allows you to use the tricks and VMware snapshots is not always the same thing as VMFS datastore.   As stated previously, you can easily remove this ROW and the provision of a physical server without losing a bit of data or to copy.

  YYou want to save raw images, but not all? Is that what you mean? When you import into FVP you can select the songs you want and you can set the library in the Inspector to record the files on any player, anywhere.

• Frames and Raw Device Mapping

  We used frames for some time on the storage array that we use for our 8 guests ESXi 5.5

  Of course the frames must be enabled at the end

  Array of the ports of kernel VM VMWare DVSwitch <>- <>- <>- Core Switch <>switch - Bladecenter

  If I SSH in one of our guests and to make a vmkping s 9000 to a port on the Bay, it shows that the frames are working well

  We bought another Bay of storage to be used strictly for home video of a surveillance system. I called cameras server that runs as a virtual machine. I added to it a 3 TB of this new array raw device mapping. Can I use the frames between the new table and the virtual machine that uses the RDM? I'm a little unclear on the string "end-to-end" when you use a RDM. The beginning of the part of the string is shown below. Do not know whether or not the RDM traffic crosses the DVSwitch

  Bay <>- Core Switch <>- Bladecenter switch

  When I SSH into a host that has one of the virtual machines with an attached RDM and use vmkping s 9000 to a port on the table ROW home that doesn't

  I have a vlan not routable separated for all traffic storage

  Usable for RDM frames? If yes how to do this job?

  Yes, that's why I try a ping to 8960. It seems that the frames is enabled but due to the load of package, it is a lower number. Most of the devices and or switching equipment ran to 8960-8972. Here's why.

  ICMP/Ping is not encapsulate the 28 bytes ICMP + TCP header. That is why the maximum size of the data part of package 8972 alone. Try the ping to your windows prompt to 8972 and let us know what you get.

  I hope this helps.

• How to migrate VM from\TO Raw Device Mapping (RDM) (data store)

  Hi all

  I have aske on the migration of VM from\TO Raw Device Mapping (RDM) (data store)?

  Thank you all for your support

  If you are using vSphere 5, then you can SvMotion the VM attached to a RDM (physical or virtual) with no problems. This means that only RDM mapping file will be moved to another data store without any conversion of changes on the real disc of RDM.

  Note: Do not attempt to change the format of disc thin or thick, which would cause the RDM disk converter for virtual disk.

  More info here: http://blogs.vmware.com/vsphere/2012/02/migrating-rdms-and-a-question-for-rdm-users.html

  If vSphere 4.x is used, hot and then migrate the virtual machine to another store of data will not change the format of the ROW, only mapping file will be moved. This is true for virtual and physical RDM.

  However, the cold migrate the virtual machine to another Datatore will change the ROW to virtual disk format.

  HTH... Let me know if you have any questions...

• The kernel cache exists for physical Raw Device Mapping?

  Hello

  I use a SAN storage disk attached to the operating system as "Physical Raw Device Mapping" and mounted at/mnt/disk1.

  I was lke take backup of/mnt/disk1 with "SAN Storage FlashCopy function", which copy entire disk in the SAN storage box, bypassing the operating system Linux and VMware kernel.

  Summary of the backup script is as follows.

  Step1: Synchronize "clear the cache of the Operatiog Linux system

  Step 2: umount/mnt/disk1

  Step 3: ExecFlashCopy ' run SAN Storage FlashCopy function

  Step 4: mount/dev/sde/mnt/disk1

  But if the VMware kernel cache for 'Physical Raw Device Mapping Device', "Empty the Cache of VMware" is necessary in step 2.5.

  You know VMware cache exists for P "effective Raw Device Mapping Device", and how do I rinse it out.

  Thank you.

  Your proposal is false. ESXi is not linux and does not cache for VMFS.

  ESXi does not cache the IO VM guest operating system receives IO acknowledgement when the disk controller to acknowledge completion of e/s.

  ESXi doesn't have any cache for RDM, what is physical or virtual.
