• Storage vMotion - WITH RDM? - Or will they ignored most of the time?

  Hi all - I have a storage vMotion, 5 hosts in the cluster - five or 6 virtual machines with RDM are pinned to specific hosts for the love of the DRS, but I want to go where the readers of the OS, then to VMDK is one San to another. If the virtual machine has a C:\ drive on the data store, all the other disks on the virtual computer is through physical RDM. ALL I need to move is the c:\(VMDK) in the process of storage vmotion.

  Time without are connected and work today to the ESX host in the cluster, all hosts are sized to see the RDM.

  My question is, when we go to perform the storage vMotion, how to avoid such failure? the RDM are my concern in the past, I think I remember a machine do not migrate when he had attached RDMs.

  any comments or thoughts would be really useful.

  You can also move the ROW pointers with the data store 'change' - Assistant. Just be sure to select "same as source" for the format of the target disk. If you choose thick or thin, the RDM will be transformed into a VMDK, but with "same format" simply the ROW pointer is moved to the new data store.

• 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.

  Please notify

  Normal VMotion with RDM, whether virtual or physical compatibility mode is possible and fully supported. Storage vMotion is supported too but real data RDM physical mode can be moved in the process.

• Machines MSCS with RDM, how to change the data store?

  
  Hello world

  I'm having a problem of displacement of 2 machines with RDM disks.
  We have 2 guests ESxi 4.1 with virtualcenter, but no license for vmotion.

  This 2 machines is building a MSCS Cluster (Microsoft) (file server) with multiple disks (5) RDM,
  for a total area of 8.9 TB. Of course, for use with MS cluster, the WDR is with physical compatibility.

  The problem is that the local vmdk (and also rdm.vmdk files) for these 2 machines are on the local data store (a machine for each host) and I need to move them to the shared storage. But if I power off of a computer and trying to change with the ROW data store attached, I get an error because the VMFS of the commune dastore (block size = 1 MB) does not support these large files (up to 2 TB).

  I read a lot of articles
  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1031041
  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1026256
  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1002511
  and a few other discussions of communities.

  In accordance with article
  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1005241

  I tried to turn off the machine, remove the RDM, migrate to another data store, and then reconnect the RDM.
  There is a big problem with the last point, because I don't know how readd the RDM manually (vmfsktools?).
  I want to add an existing drive, but he was in local storage, and I don't want more no reference to the file in the local storage...
  According to the documentation of vmware for MSCS, the second node of the cluster disks can be added simply to add a drive existing and selecting the
  existing node. If it is no problem of shared storage, but the host cannot read local storage to another host...

  Any suggestion to migrate a computer virtual with RDM shared storage room? Thank you

• VMotion VM with RDM failure

  I am facing a problem that I can not vmotion/migrate a VM with RDM. Other virtual machines with the RDM can vmotion, but I have a problem with a virtual machine. The error is:

  VMware KB: Difference between RDMs physical compatibility and virtual RDM compatibility

• Poor with RDM only when added to the CAB MSCS cluster performance

  Hey guys, thanks for taking a peek at this question... I'm looking for some ideas.

  I have 2 virtual machines running Windows 2008R2.  They put MSCS in place and works as a taxi (cluster across boxes).  I use a 7500 VNX, fiber channel and RDM physical drives.  Is on an 8 node ESXI 5.1 v1117900 implemented.  Functionally, everything works fine.

  The problem is that the performance is very poor on only the RDM that have been added to the MSCS cluster.  I can take the same drive, remove the cluster, run IOmeter and it's fast.  I add to the cluster, MSCS, leaving in storage, and it is 1/15th the IOPS performance / s.  Remove the drive of MSCS and it goes back to when you run as usual.

  I tried different controllers SCSI (LSI Logic SAS vs Paravirtual) and it doesn't seem to make a difference.  I have physical MSCS clusters that do not seem to present this kind of performance problem, so I wonder if it was not something goofy with the MSCS on the configuration of virtual machines.

  I've already implemented in this article: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1016106

  I saw this poor bus rescan the performance issue until I put the RDM perpetually booked, but it was not a problem since I implemented the fix.

  For any help or suggestion is appreciated...

  Thank you

  Recently, I upgraded my esxi from 5.0 to 5.1 environment and have a bunch of systems with RDM. I had a problem as well. What I found, was that during the upgrade it changed all the policies of path to the LUN and rdm, it's the turn of robin. This causes a huge performance issue in my environment. I changed all the paths to MRU and it solved the problem.

• SRM 5.1 & NetApp - VM with RDM and MSCS

  Hello

  I implement SRM 5.1 with NetApp (with SnapMirror) and I have several questions:

  -Replication of the volumes through the table Manager, runs successfully

  -How the replication of virtual machines with RDM? can also be done through the Bay (with SnapMirror) Manager or better do with vSphere replication. Can be achieved by vSphere replication?

  -Make all the tips for the replication of virtual machines in a cluster of Microsoft?

  Thanks for all!

  I'm not a person of NetApp, but this should be documented in the documentation of the SRA.

  Another point is that MSCS RDM cannot be configured with political tourniquet (which is usually is the default value for NetApp LUN). You must reconfigure the LUNS to MRU.

  Edit: Just have done a quick search on Google and found this pdf that looks like what you need:

• Add new storage "opération TimedOut" with RDM LUN on host. Pls Help

  Hello

  Installation program:

  4 ESX 3.5 hosts each with 2 HBA adapter connected to the HP MSA1000.

  Question:

  I set up MSCS SQL 2000 with RDM through host, MSCS failover without problem, performance wise is not a problem at all too. But the problem is that if the MSCS SQL resource is managed by the Active virtual machine that is running on host1, I can navigate to storage / adding LUNs, set in shape of new LUN with no problems.

  If I want to add new storage on the other host "host2" I received the error "Tor time to ask"is it because of the resource ROW being busy serving the machine virtual active it is why the host not allowing do not change with the addition of new storage?

  Guests see these LUNs. I can add the data store or to do a new analysis also long the LUNS are not presented to the host. Also I can browse the data store, able to see the addition of Storge Wizard when adding new

  Data store and make a new analysis only on the host where the operation of the active node. Suppose the preseneted RDM LUN on host1 and host2 and VM SQL running on host1, I can only browse the data warehouses, a new analysis and add new storge to this host. I can't do the same thing with

  hosts2.

  But if I take these "RDM LUN" LUNS in host2, host3 and host4. I can do a rescan, adding other LUNS as the RDM presented to the virtual machine, able to see the add storage wizard.

  I googled the error and found that the Ontario server is question, or DNS

  Best regards

  I had similar questions to those two problems here where I couldn't add a data store as he would expire and I got the long startup time. I also use RDM which I use for MSCS in the whole of boxes 2. Here's a quote from my previous post in which I found a response that helped me. Changingthe SCSI retry time increased my boot time and allowed me to add one more time without the question of the time-out, data warehouses.

  Response to previous Post:

  I did some research and I think I've made some progress. I found that I get lots of SCSI errors in the VMkernel newspaper. I did some more research and found out that I can change the time retrying SCSI 80 to 10 and it has done wonders for my time to reboot. Now, instead of taking 20 minutes to start, it takes less than 5 minutes now. Much better. I made the change in the host-> advance-> SCSI--> SCSI configuration try again. 80 a the default and 10A was suggested as being a good value. It helped and I will keep an eye on what can make the effect, but so far it has helped with startup times.

• SQL, vmotion and RDM

  Hello

  I am a beginner and I would try to create a virtual machine with a database of sql 2005 with rdm lun.

  I created my vm on a lun that is shared between two hosts esx (for the vmotion).

  Now, I would like to add 2 rdm lun. The first on lun raid 5 for the data base, the second on a lun raid 1 for newspapers.

  But when I add the row on my vm as the vmotion and I try to migrate the virtual machine to the compatibility of field, it is 'impossible to migrate from esx1 to esx2. Virtual disk is mapped lun direct access which is not accessible.

  you have any suggestions?

  Sorry for my English

  Hello

  LUNS that are configured for the RDM plan must be visible on all ESX servers participating in the activity of vmotion. They must also have the same ranking of LU.

  for example

  ESX 1:

  READ 0 = store VMFS

  READ 1 = RDM

  ESX 2:

  READ 0 = store VMFS

  READ 1 = RDM

• MSSQL server VM cluster should be in the same host or different hosts with RDM

  Could someone me on how to place the code SQL cluster s VM with RDMs in ESXi hosts for advice.

  What is the best practice to place the SQL VM s in ESXi hosts.

  Affinity or an anti-affinite...?

  Appreciated your valuable answers.

  Depends entirely on the use case.

  • 2 MS SQL nodes on the same host to see the availability of the software
  • 2 nodes on different hosts to see the availability of the equipment

  I'd say MS Clusters on the same host (at the time of HA and vSMP FT) are redundant VMware features and represent an increase in management fees. The MS cluster on hosts provide something in addition to what VMware vSphere alone can provide!

• Live VMotion with vGPU

  Is a feasible direct VMotion with Horizon 6.1 and 6.0 vSphere assuming that both hosts have the same graphics card?

  It depends on using vSGA Yes, you can, but if you choose the vDGA option, unless I missed something, you can't, take a look here: https://www.vmguru.com/2014/03/vmware-horizon-view-graphics-vsga-vs-vdga/

  And view 6.1 documentation: 3D Rendering for desktop configuration

  Because vDGA and NVIDIA GRID vGPU use pass through PCI on the ESXi host, VMotion directly is not supported. vSGA and 3D app supports direct VMotion.

• RS 5 with netapp SRA, FCOE site iSCSI with RDM

  Hi team, could someone please help to veify if it works in this scenario.

  We have PROD site running vmware vcenter 5.0, esxi5.0, SRM 5.0, Netapp 3210 ONTAP8.1 version file server. The VMs are windows Server2008, MS SQL2008 as major DB. Virtual RDM database files. Only FCOE for this site. AD is a physical Server 2003. The rest are virtual machines

  We offer you to have SRM for DR site deployment. The DR site is synchronized with netapp SRA snapmirrror, controlled by the console SRM5.0. Recovery site has no FCOE, only iSCSI and NFS license availble. Always RDM but using iScsi. vCenter 5.0, 5.0, netapp ONTAP8.1 2040 esxi.

  My questions are:

  1. If VMware SRM support DR failover for this case with the different protocol, PROD is FCoE, iscsi DR

  2. If the SRM supports failover with RDM in our case

  3. If the AD DR Server site need to be installed as a new best practices, or we will have to use SRM to switch production announced on website of Dr. What is recommended.

  4. If the physical AD can be kept as the common way and always taken SRM supported

  5. to the recovery site, which is the best practice? To use NFS to store data and iSCSI for iscsi? Or store data and RDM using iSCSI LUNS to simplify?

  
  

  Thank you!
  

  1. Yes
  2. Yes
  3. I would recommend if possible having a domain controller AD, already running on the DR site - it may be a virtual machine
  4. Yes, the PROD site domain controller can be physical
  5. I'd keep all compatible iSCSI so so -.

• Proper installation and use of Vmotion with 4 NICs

  I have a new VMWare esxi to 5.1.0 two server installation.  Each server has 4 network cards.  I currently have two NICs configuration for iSCSI and installation of two NICs for network administration.  What is the best way to add vmotion in this environment?  Should I include it with iSCSI or administrative network?  The vmotion network must be on the same IP network as the adminstrative or iSCSI network or can it be it's own pattern IP?

  I have a second environment where each server has 8 cards, vmotion is on its own network with its own network card and thus the reason for my lack of knowledge.

  Thank you

  Welcome to the communities...

  My suggestion would be as below:

  What is the best way to add vmotion in this environment?  Should I include it with iSCSI or administrative network?

  Suggest to include vMotion with (administrative) network management traffic, create a second group of VMkernel ports for vMotion on the network to management switch

  For the management network-> Set as active nic1 and nic2 as standby

  For vMotion Network-> NIC2 defined as asset and NIC1 as standby

  The vmotion network must be on the same IP network as the adminstrative or iSCSI network or can it be it's own pattern IP?

  Best practice is to have a separate network for vMotion traffic
