• 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 In my view, that the KB is just outdated.

• 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...

  Hello

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

• How to know the difference between RDM physical and virtual

  Hello!

  How can I see if a RDM (RAW device) is physical or virtual?

  I can see it in the vmx file or easily elsewhere?

  I have a few servers running both VMFS and RDM disks inside the virtual machine, and when you use ESX Ranger and make an instant backup, they are ignored to be backed up.

  Grateful for a response

  When you change the settings of the virtual machine and choose the RDM - there will be a radio button selected for the RDM mode, it is - it is really obvious. She'll be selected for the physical or virtual.

• RDM (Raw Device mapping) physical or virtual?

  Hello:

  I have VM and will add a hard drive.  RDM will be, but I was wondering what "Compatibility Mode" choose "physical or virtual?

  It's my production Oracle machine and this new drive will contains about 500 GB of DATA...

  I think it would be nice to use the 'virtual' mode, to make snapshots, but I'm worrying that, for this one big disk, it will take a lot of time and a lot of space... There are other arguments that I should consider?

  Thank you very much.

• Physical to virtual (P v) Conversion of vCenter Server

  What are all the things I need to think about when convering vCenter server from one physical machine to a virtual machine?  For example:

  1 if the SQL database is on the same server, it can be corruputed?

  2. If I create P to V would be vm and let it sit for a day, while the physical vCenter server is in place, what is happening with Active Directory when I stop the physical and virtual vCenter server takes over?  The vCenter Server virtual would have a less recent synchronization with Active Directory than the physical server, I just stopped.  No problem?

  Welcome to the community-

  (1) as long as the DRS HA cluster hosts see data even warehouses there will be no problem

  (2) once more, also longer than the nose can see data warehouses including the LUNS as the RDM it home should be without issue.

  (3) Yes multiple instances of the free version of ESXi can access LUNS shared - Yes it can be used in a production environment, but remember you can not handle the free hypervisor with vCenter.

• VMware 5.1 with compatibility virtual RDM and Microsoft SQL Cluster mode

  Hello

  I am a bit confused by the VMWare documentation and hope someone can point me in the right direction.

  I want to know if it is possible and supported to create a cluster of SQL 2008 R2 2 nodes (Server 2008 R2 SP2 are VM) on a 2 node cluster VMWare 5.1 with the use of Virtual RDM compatibility?

  When you read the PDF on vsphere5.1 on the link below on page 9, there's a indicating note 'NOTE Clusters on multiple physical computers with no-pass-through RDM is supported only for Windows Server 2003 clusters. It is not supported for clustering with Windows Server 2008. »

  http://pubs.VMware.com/vSphere-51/topic/com.VMware.ICbase/PDF/vSphere-ESXi-vCenter-Server-51-Setup-MSCS.PDF

  So that means that I want "a 2-node cluster sql 2008 R2 server" is not supported?

  But I also found this link below and in the table of the column on the Cluster SQL line RDM is said 'yes' with a 2.

  VMware KB: Microsoft Clustering on VMware vSphere: guidelines for supported configurations

  Means 2/redirects-> for more information on shared disk configurations, refer to the Disk Configurations section in this article.

  -> Disk configurations

  • RDM: Configuration using a shared Quorum for storage or data must be on Fiber Channel (FC) based on RDM (physical cluster across boxes "CAB" mode, virtual mode for cluster in a box "IPC") in vSphere 5.1 and previous versions. RDM on storage other than CF (iSCSI and FCoE) are supported only in vSphere 5.5. However, in earlier versions, FCoE is supported in very specific configurations. For more information, see Microsoft clustering solutions table above note 4 .

  What follow-up note4->

  1. In vSphere 5.5, native FCoE is supported. In vSphere 5.1 update 1 and 5.0 Update 3, two cluster configuration of the node with Cisco NAC (VIC-1240/1280) cards and driver version 1.5.0.8 is compatible with Windows 2008 R2 SP1 64-bit guest operating system. For more information, see the VMware hardware compatibility guide:
     • Cisco UCS VIC1240
     • Cisco UCS VIC1280

  This means that it is suuported, I "m confused.

  Hi Bypy,

  Two windows 2008 R2 SQL virtual cluster nodes with RDM is supported only for the IPC or Cluster In a Box that is to say if the two virtual machines reside on the same host ESXi. The same configuration is not supported for the cabin or Cluster across boxes (virtual machines running on different hosts ESXi).

  The CAB, you go for the physical RDM mode.

  According to this link, http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1037959

  SQL Cluster using windows 2008 R2 is supported for both physical and virtual mode RDM. Between physical and virtual mode depends on whether you want the CAB or IPC respectively.

  I hope this helps.

  See you soon,.

• How to-disk snapshot RDM in physical mode and RDM issues.

  Hi all

  I want to upgrade a few VMS version 4 to 7 production equipment, so I can save them using vDR.

  One recommendation is to take snapshots of the necessary virtual machines before the hardware upgrade, I'm unable to do so because of the disc RDM in physical mode.

  I'm looking for the answers to the following questions:

  -How do we or can we change disc RDM in physical to virtual (all risks, process involved, etc...)?

  -How a US dismantle and mount RDM disk without losing any data?

  -Can we dismantle and mount RDM disk to a different virtual computer?

  -We convert RDM to a normal virtual disk on vmfs data storage?

  Enjoy your time reading/response.

  Ta

  Hi dia,.

  Please find the answers online.

  -How do we or can we change disc RDM in physical to virtual (all risks, process involved, etc...)?

  Remove the drive from RDM virtual machine and add the ROW again using virtual mode.

  (Do not select the option Remove evil in the virtual machine and delete the files from disk)

  -How a US dismantle and mount RDM disk without losing any data?

  Same as above. (if I understand your question)

  -Can we dismantle and mount RDM disk to a different virtual computer?

  Remove from VM-1 and add the VM-2 by using the VM settings.

  -We convert RDM to a normal virtual disk on vmfs data storage?

  Yes, we convert RDM on the virtual disk using the Migration (SVMotion). To do this the virtual machine must be powered off the coast of the State.

  Let me know what answers your questions.

• Physical to virtual clustering on vmware

  Hi all

  We plan to convert one of our (AD) domain controller in Virtual box, then must make grouping with another physical box (DHCP).

  Can someone help me on this...

  First need to know

  1 can we do clustering on physical Virtaul-bix in a windows environment. ?

  2. Keeeping (ADC) box of vmware domain controller is recommended... a... ? If so can we Virtaul virtual or physical to virtual clustering.

  Note: The controller (ADC) of area intended only DHCP enabled no specified ROLE on this.

  Thanks in advance

  Concerning

  Konate

  What do P2V ADC?

  This is a wrong approach

  AD is a database structure that could not be stopped on a running system.

  So the only way to make a coherent P2V, it is use a cold conversion (but you need the Enterprise Converter) or try to do it in Restore Mode Active Directory.

• Possible to have the physical and virtual units of ESA in the same group?

  Given the scarcity of available information about virtual appliances, anyone have any ideas if it is possible to run a physical C160 and a C300V running the same version of ASyncOS in the same cluster.  I need to migrate from physical to virtual and has been evalualting the possbilty of the migration to the C300V from the C160 by adding a C300V to a cluster and then decommissioning the C160.

  Someone know about this?

  Thank you

  Nathan-

  Yes.  You can, as long as the appliance and virtual appliance running the same AsyncOS.  The "clusterconfig" command will work in the same exact way.  You need to just make sure that your C300V has the featurekeys loaded in order to run the cluster.

• Physical vs Virtual DMZ

  I implement the vCloud Suite of products in a multiclient environment and currently do not have a demilitarized zone.   In seeking to define what the DMZ network will look like, devrais I guess that I need one that is defined by a separation of physical networks such as the following:

  (Outside of the physical <>- physical <>- DMZ-<>- Firewall firewall network <>- internal network)

  Is to have a demilitarized zone in a conventional, as above, with two firewalls of both sides, always recommended?

  Can I do the same thing with POSSIBLE and when is it appropriate to set my DMZ in software vs hardware?

  Hello

  Well the following will work using only virtual Firewall:

  <->outside the physical switch <->outside Teddy <->VDS <->FW <->VDS DMZ <->FW <->Outside outside inside VDS

  Physical switch <->Teddy <------------------------>VDS DMZ DMZ DMZ

  Then attach a physical DMZ via the DMZ VDS and specific ports outside your chassis and a physical switch in the DMZ upstream.

  Or the following if you want to combine physical and virtual firewall

  Outside <->physics FW <->DMZ Phsysical Switch <->Teddy <->pvNIC <->DMZ VDS <->FW <->DMZ VDS from inside the DMZ

  If you want to use a DMZ or not depends on what you're really trying to do.

• Conversion of physical server into a virtual machine

  Hello

  I would like to take a physical server and convert it to a virtual machine on the same box.  I'm new to VMs, so please tell me if this is possible and if yes, what is the best way to do it. Right now, I think these are the basic steps:

  (1) take operating system image current (2003 Server STD) using Acronis.

  (2) wipe server and install ESXi 4.

  (3) use the free VMware Converter to convert the Acronis image to a guest VM on the ESXi host.

  Will this work? Am I missing something? The traps that I should look out for?

  A few questions more to go with this:

  -J' currently have an ESXi 3.5 on a desktop host. Wouldn't be better to convert this machine on the fly to a guest on this 3.5 host, then move the guest to the new 4.0 host once it is ready?

  -This server is now an application server and has a few databases, such as WSUS and Kaspersky Administration kit and maybe something else I can't think right now. Is that causing trouble with the DBs in the transition from the physical to the virtual?

  -The machine has also acts as a file server and is connected to our iSCSI SAN. Will be a problem or I would be able to remap the LUN to the virtual machine quite easily just like I did to the physical machine?

  Sorry for the long post. Any help would be greatly appreciated. Thank you!

  As long as you can take decisions associated with the image with Acronis and then convert it to a virtual machine, I think this is a good approach.  You can convert the server in a virtual machine running on your ESXi 3.5 environment but I would not run a server database production on class workstation hardware.  The performance would be probably pretty bad if you had a large number of users hitting that database.  As for using Acronis I know that it is supported but in the past I have never tried to convert an Acronis image for a virtual computer by using converter.

  The databases themselves should not have any problem on a virtual machine.  SQL runs in a virtual machine and saw complex databases even accomplish a lot.

  Reconnect to your iSCSI SAN shouldn't be a problem either.  You must ensure that the networking on the newly built 4 ESX host is configured to allow you access to all the VLANS required (iSCSI VLANS, server VLAN, etc.).  It is an important step to ensure that you have right or you will not be able to reinstall your iSCSI LUNS, once the server is converted.  Once the networking is configured the process of reconnecting to the iSCSI LUN from inside your virtual machine is the same as if it was physical.

  Good luck!

• Physical to virtual conversion

  I will be converting a physical server to virtual in a few days. The server is located in a RAID 5 partition with a system of 12 GB drive and a D: 90 GB drive.

  When I go to convert, is it wise to increase the space on the system drive of 12 GB to 15 GB?

  Also, how can I change my username to vmware. It's driving me crazy!

  Thank you

  Thanks BuRinger,

  Let us know if problems..,.
