• great svMotion RDM

  Looking for world real experiences on someone who has svMotion'ed a big RDM or vmdk...

  I am planning on doing a RDM 1.4TB (in virt compat mode)

  Just curious as to how long it took, and if he had problems in such a large Chuck of data moving. I am worried about how long it may take, and how the snapshot will face being here for so long.

  He'll go to a unit number logic on the same SAN with the same level of raid etc. The SAN is an eva8400. No Nottm.

  It is a file server, and access ramps up between 07:00 - 18:00, so outside of the times would really go

  I just did a 1.5 to non - RDM vmdk, a week or two ago.  It was between 2 datacenters with 10g connectivity.  It took less than a day (I guess that 10 to 12 hours, but I don't remember for sure).  It was on ESXi 4.1U1.  I did it during the day, but it was a test system with a database MySQL on this subject.

  I did a 600 + GB non - RDM vmdk between these same data centers while we were still in ESX 4.0 and it took several days.  Moral of the story is to make sure that your ESX installation is current...

• Shared RDM or VMDK of NLB Cluster?

  We have a cluster of load-balanced NETWORK R2 2012 hosting a web application.  We would like to have a shared storage location that can be referenced by each server in real time.  I created a LUN and added a RDM and VMDK, but the other server sees no change, unless I re - mount the drive.  I added the channel multi-writer in advanced options for the two virtual machines thinking that can solve the problem, but nevertheless - I suspect that this could lead to an easy way to corrupt the files.

  That said, what is the best approach for this?  We currently have a network share that is referenced by each server, but for me that adds variables to a network problem, causing problems, or the account used to authenticate the part does not.

  What other options do we have?

  Thanks to this, we recently a million times.

  NTFS (without CSV) is not compatible with the cluster file system and as such cannot handle simultaneous write access from multiple hosts to a block storage device. Your configuration will not work in a world purely physical as well.

  On April 27 I bought RDM + for the storm of App World. Because the operating system updated, my original storm I forgot the license code. After contacting support services, a form, they told me that the code should appear under 'details' in 'My World'. This is not the case. I still have my original confirmation email (removing information) personal, and I'd rather not have to buy twice. Is it possible to re - get an activation code?

• RDM for machine P2Ved?

  Guys,

  We plan to virtualize a server who got (200 GB) SAN attached storage.

  Rather than energize the drive that uses space SAN, I think to present this record in particular a RDM for VM.

  • Is it feasible?

  • All the challenges?

  • I have to UN-map the physical server LUN first inorder to to the virtual machine as a RDM?

  • I suppose, that just I have to present the same LUN on different ESX hosts in the cluster to use the Vmotion/DRS, is it true?

  • Best practices?

  1: Yes

  2: not that I can think of to...  Why RDM on VMFS?

  3: I'd do it.

• 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?

• Storage vmotion a VM with so many vmdk and RDM for NFS

  I try a virtual machine that has so much Storage VMotion vmdk and RDM disks to a NFS data store.

  I do NOT need convert the RDM disks just move the pointer with the VMDK file will be converted.

  Is this possible?

  Now if I try this hot svmotion, I get an error on the RDM which set out the following "virtual disk" drive hard 3' is a direct access mapped LUN that is not supported on the data store 'myEMCNFSds'.»»

  If I try this svmotion cold then I get no warning, but it seems that svmotion is trying to convert the RDM NFS drive.

• Live Conversion RDM in VMDK

  Hi all

  I have a VM (which cannot be turned off) on Esx 4.0 and I want to use storage vmotion to convert a disk (virtual machine has several disks) of RDM VMDK.

  Any advice or experience?

  Thank you very much

  The main question is: is this a way RDM physical or virtual RDM.

  of http://kb.vmware.com/kb/1005241

  For vSphere 4.0 and higher, the virtual disks and Virtual Mode RDM pointer files can be moved in the destination data store and can be converted into discs supplied thick or thin-set during the migration until the destination is not a NFS data store. Physical RDM Mode pointer files can be moved in the destination data store, but cannot be converted.

• Is it possible to make RDM for my Dell Equallogic SAN?

  I now have this connectec by iSCSI but I was wondering if I could make the Raw Device Mapping. It is grayed out and the server is off I understand is necessary to make it work.

  Must be missing something.

  Yes it is possible,

• How files request for vmdk with location of store data using perl sdk

  Hello

  I need to retrieve a list of (xxx - flat hard) and vmdk files for a virtual machine on an ESX Server.

  The virtual machine I have has two disks that are in different data stores.

  I changed the /usr/lib/vmware-vcli/apps/vm/myvminfo.pl to dump the full data.

  I spilled the $vm_view and found that the data you are looking for do not print.

  I'm new to VMWare and don't know how to go forward.

  Any help will be greatly appreciated.

  Thanks in advance

  You should be able to use just LayoutEx property of the VirtualMachine.  Keep in mind this property gets refreshed on a schedule, so don't always present not unless you explicitly referesh it yourself.  However, that can add some overhead VI retesting the data store (s).

  The attached script is quite simple, but it can help you get started.  To % disk_parts hash key is the key of the device, you can use this to get configuration-> hardware-> device information.  The string under layoutEx-> disc keys should be descriptor-> measure.  You can query the type of the object file if you need to be sure or want to only print as well.

  You can exit the script in certain functions or map() calls to make it more readable.  You need to work through the key tables nested loop, so it would probably be good to format into something easier to follow.  Another option would be to create a hash of the file of the key values card, so you can do research without expensive loops.

• Server for vmdk hardware backups using vRanger connection

  Hello

  We try to implement vRanger connection for backup of our VMS (ESX 3.5) and would like to have installed on a stand-alone server. There are currently 36 VMs that is likely to grow. Each virtual machine has a disk of 10 GB C residing in SAN. We want to save these files vmdk SAN to the server where vRanger connection is installed.

  Could anyone here suggest some options for a server to have it put in place? Given that the size of the files would be around 400 GB for now and much more later, the speed of the hard drive must be considered too.

  Thank you.

  Cool! So what kind of records should I go then?

  What is your budget?  SAS is the fastest, but we are talking here about 400GB drive will cost twice what a single 1.2 to or even 1.5 TB SATA.  Even if you have the budget for it, it's a complete waste of money, since you can get 4 times the storage for the same price.

  RAID 0 will give you the most performance, however if you keep several revisions on your backup disk, maybe not prudent to use the RAID 0 in the long term, but there again this depends on your backup strategy, you want backups LONG or SHORT term?  If you make full backups every week, as we do, RAID 0 is fine.  We can accept the risk given that do us COMPLETE each week and because backups are unexpected, not to archive, it is not a big problem for us, but every company is different.

  Network is not your main concern, however, if you have a decent network of 1 GB, that's all you need.  Just buy whatever you can afford for storage, if backup speed is your main concern, go SAS, if not go SATA.

• Compare the performance of virtual machine using RDM for physical Machine with HBA

  With the help of some great users, I recently converted a node of a cluster, MSCS running Server 2003 and SQL 2000 to a virtual machine for the cluster resulting has a physical node and a virtual node using RDM drives. See http://communities.vmware.com/thread/187822 If you're interested.

  Now my question revolves around performance. Colleagues who manage programs running on that cluster related that a backup every night a database on the thesystem take 10 minutes on a physical hardware and takes 30 minutes. A restoration took 45 minutes and now takes a little less than three hours. Is this kind of drop in performance to be expected? Is there some specific changes that I can look to improve performance.

  The virtual machine works like a single virtual machine on a machine of update3 ESX3.5. ESX server has two processors Quad-cores and 32 GB of ram, 30 GB assigned to the virtual machine.

  Any help or pointers to more information would be greatly appreciated.

  Check your card vSCSI.  If you P2V'ed, you're likely to have a Buslogic adapter.  The Buslogic adapter will limit the length of the queue 1 and limit the I/O.  Replace with the free and see if that helps you.

• using disc RDM for SAN management capabilities

  Hello

  I had a quick question.

  Many other uses of RDM, I read that he is used to running on virtual machines SAN management agents.

  I'm just trying to understand what applications (examples?) could be used on virtual machines that would allow SAN management operations.

  What I'm trying to understand, that's why some would install an agent on a virtual machine SAN management? no use case?

  Thanks in advance.
