• Physical RDM virtual RDMs taken in charge in vSphere 6.0

  Anyone know if this process in KB 1006599 works in vSphere 6.0 +?

  VMware KB: Switching between physical and virtual compatibility modes in ESX/ESXi, a mapping of raw data

  We are about to move a bunch of RDM to VMDK, but we need to convert physical to virtual RDMs first (you can live storage migration [to VMDK] with virtual RDM but not medical examinations). The other part of the story is that we are running vSphere 5.5 and are about to upgrade to vSphere 6.0

  KB wrote on October 17, 2014 and I wonder if this is still the method support in vSphere 6.0 and that it has not been updated; or if it is no longer supported, in which case I have to do the migration before the upgrade?

  Thank you

  I see no reason why this will not work in vSphere 6, given that the procedure is simply to remove the physical RDM disks and add them again as RDM virtual disks... In my view, that the KB is just outdated.

• Convert the RDM virtual disk

  I have two or three of Phsyical MSY and want to conver in VMDK... What is the process to do this?

  I got your PM, basically just treat your virtual machines of RDM, such as a physical server and convert it through the process and it will be automatically created in VMDK format.   Just make sure you select the disks attached to RDM and it can convert.  Which requires you have enough storage space, but the same process as you did with the physical server.

  If you found this information useful, please consider awarding points to 'Correct' or 'useful '. Thank you!!!

  Kind regards

• Convert a RDM a VMDK (virtual disk)

  We are currently running vSphere/ESX 4 and EMC SAN.  Our SAN is replaced by an updated model.  Dell/EMC will perform the data migration and recently told us that if we want to keep our RDM they would be able to copy their bit to bit.  Which means that we cannot change our size of the LUN.

  They told us to move our existing data to LUN more (or less) that we need to convert our RDMs VMDK.

  We currently have three separate virtual computer that will connect to a RDM on SAN (Exchange, SQL, and a file server).

  Is it possible to convert the RDM in VMDK?  If so, how?

  I searched the forums and has been unable to find an answer.

  Keep your support ticket opened until the problem is solved - you did update the VMware Support?

• physical conversion RDM virtual RDM

  Hello

  is this possible without actual destroying RDM and constituting in RDM virtual physical? We have more than 2 TB of data on it and online extension is problem because virtual RDM must be restarted to recognize the new drive size...

  Damir

  Hello

  It can happen only when the virtual machine is turned off.

  Best regards

• Problem of cluster Failover MS after physical RDM conversion to VMDK

  Hello

  Last week I had to migrate 7 x 2-nodes virtual MS Failover clusters to a new data center. All clusters have been configured with the configuration of the cabin and all shared disks were in physical RDM mode.

  The target data center does not RDM disks so I had to convert all RDM disks VMDK files and use config before the migration of the IPC.

  I used vmkfstools to convert VMDK eagdrzeroedthick RDM files.

  5 clusters have been migrated successfully, but two cluster got strange question even if the procedure for all groups was the same.

  So in two groups, I have a problem where the second node in the cluster can not put online some of the shared disks. The first nodes in the clusters have no problem with the disks/SSP.

  But when I try to failover of all services, the second node may not bring online disc 1 or 2 shared, even if she can put the other shared disks online.

  VMKernel.log is not errors or warnings. I checked the configuration of virtual machines and everything seems OK.

  Any ideas what I could check?

  Just in case anyone else is facing the same problem.

  I could not find the root cause of the problem, even if it's without a doubt the conversion that triggered the problem. However, we found quite a simple solution - added new shared VMDK files, copied the files over and replaced the defective discs.

• Help with converter and RDM

  Hello.

  I need to convert a virtual machine that has a disc RDM.

  That's what I did.

  First convert the machine with stand virtual converter only, but excluding disc RDM.

  Then, when the new VM is ready I just add the RDM disk, but windows does not detect it.

  After that I have rescand disks but nothing happens.

  I added the new drive virtual and physical also.

  Why the STRP operating system does not detect the new disk?

  Thank you...

  Yhe comments should see the disc RDM (both physical and virtual).

  Make sure that your have remove old drivers comments (for example the HBA driver) and you have installed the latest VMware tools.

  Then, add the RDM and rescan the drive.

• Do > 2 TB physical RDM NEED Directpath IO?

  I've been struggling with this for over a week now so I could really use some advice.

  5.1 ESXi

  I need to install three hard drives 3 to and give them direct access to a virtual computer running FreeNAS (or other) for a ZFS ZRAID configuration to store data.

  From my research, it looks like a physical RDM is my best solution. I want that the BONES of the VM to exert direct and complete control to readers with title bit VM intervention as possible. Reason being, I want readers to be able to be exchanged in a physical server to spare if necessary to recover the data.

  I am able to do a physical RDM using the command line and I'm able to add them in a virtual machine. Once attached, they do not work in the operating system. The operating system can see the disks, but may not use it.

  I am unable to make the virtual RDM because obviously, readers are more 2 TB - 512 k.

  Where can I activate? Do I NEED to have material supporting Directpath IO to use the large RDM? I can't confirm this, but it's the only thing else that I can think of. New versions of ESXi should support up to 64 TB with the RDM...

  My hardware does not support Directpath IO so I can't spend it just a map of entire storage with the disks attached. But I can buy a new motherboard supporting the pull-out decision if that's the answer. Also, for the physics of the RDM will I need to pass to the virtual machine a whole controller (card) or can I just use the physical RDM as on the use of the SATA connectors on board?

  Any advice would be greatly appreciated. ;-)

  What type of storage do you use? ISCSI or FC?

  You certainly don't need direct i/o path for a raw device mapping physics > 2 TB (-512). So that you can safe money

  What's that it is mentioned in vmkernel.log when you join the RDM?

• Convert a RDM

  Anyone can guide me please how to change a virtual RDM Mode to a physical RDM Mode.

  I therefore need an active Windows 2000 Adv Server VM. The number of logical unit on the backend is a Symmetrix VMAX drive, running on the virtual machine as a virtual RDM Mode.

  Thank you.

  Turn off your virtual machine

  Remove your disk of rdm. Make sure you know what is the path

  It readd as a raw physical disk

  * Note Remove any snapshots that you have

  Here's a walkthrough, if you need it.

• SQL snapshots in physical RDM mode help?

  If a virtual machine with a drive located on a RDM in physical mode, doing things like SQL snapshots work?

  There is a discussion where some people wondered if them soon be virtualized servers SQL must use internal iSCSI client to connect directly to a SAN logical unit number or if you are using a physical RDM mode. They were not sure if features like SQL snapshots work.

  Operating system doesn't "know" what type of disc it uses (virtual physical RDM, RDM virtual disk), so that all the functions as snapshots made within the OS itself will work the same. It's only the instant VMware that has no effect on a physical RDM.

• Limitations of architecture with replication of VM with physical RDM Mode

  What are the Limitations of Architecture with replication of VM connected with physical RDM Mode in vsphere replication. Why VMware does not support this?

  I will add some colors to the response of GS. A particular interest with regard to the physical path RDM (pRDM) works, summarize these two chips of the article:

  • Physical mode specifies minimal virtualization SCSI of the mapped device, allowing greater flexibility for SAN management software.
  • VMkernel passes all SCSI commands to the device, with one exception - the REPORT LUNS command is virtualized, so that the VMkernel can isolate the LUN to the virtual machine owner. Otherwise, all the physical characteristics of the underlying hardware are exposed.

  There is an integrated in vSphere vSphere (RV) replication agent that has several functions. In particular, she keeps track of the Scriptures to the virtual machine. When a replication cycle occurs, the changed data is replicated to the target location. The VR agent should be able to 'see' These Scriptures to follow. Given that the physical mode all SCSI commands directly to the device, the VR agent is unable to follow these changes for replication.

• PvSCSI adapter for physical RDM expandable disk using?

  Hi all

  Can anyone here please indicate if the scenario below is supported for RDM physical disk with the extensible feature in the future?

  R2 Windows Server 2012

  Physical RDM: NTFS table partition GUID 2 TB which can be expandable to 12 TB + in the future

  SCSI controller: pvSCSI SCSI 1:1

  Because the KB article: VMware KB: configuration of disks to use VMware Paravirtual (PVSCSI) SCSI adapters says:

  • Do not use the PVSCSI on a virtual machine running Windows with split volumes. Data may become inaccessible to the guest operating system.

  
  

  Thank you

  If you use physical (amp) RDM, why would you use volumes split inside the guest?  You present a lun 12 to large or smaller and covering inside the guest OS?

• Independent drive persistent and physical RDM Mode

  Hi all

  Need your opinion on taking snapshot backup in option of the few VMs via NBU 7.6

  We intend to resume via auto-created snapshot NBU, but is that all VM have persistent independent drive along with some VMs have physical RDM Mode.

  I am aware that the physical RDM mode supports not instant, but is independent of the persistent drive?

  Thank you and best regards,

• VMotion with RDM - p discs?

  I read in an online course that vmotion don't is not supported when you use rdm - p discs.

  Is this true? Why is this?

  The reason why I ask, this is that, in my essay vmotion seems to work very well in this scenario. So, I wonder what it is.

  Thank you!

  This may be a limitation MSSQL/Microsoft Clustering and not a limitation of vSphere-large: Microsoft Clustering on VMware vSphere: guidelines for supported Configurations. Someone with more experience who may be able to provide more information on this front.
