VMotion VM with RDM failure

• 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 MSCS VM´s

  Hi all

  Just to check:

  -Microsoft cluster with RDM on vsphere 4.0 - I do vmotion?

  -First disk can be created in stock?

  I read vsp_40_mscs.pdf, but it is a double check. (in this guide figure how much limitation vmotion)

  I also read http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1005241

  Thank you all

  First installed the virtual machine Guest OS drive. First disk of old versions be distributed in local disk.

  MSCS documentation:

  You can put the boot disk to a virtual machine on a VMFS volume based on the SAN.

  Can I do vmotion with this scenario?

  No, you cannot vMotion with shared disks MSCS nodes.

• Storage test 55 certification vmotion, storage vmotion fails with "Could not lock file" on the virtual machine during storage vmotion

  In my view, that it is a known problem in ESXi 5.5 Update 2 release notes, someone knows a solution yet? This is an excerpt from the release notes:

  • Attempts to perform live storage vMotion of virtual machines with RDM disks can fail
    Storage vMotion of virtual machines with RDM disks can fail and virtual machines can be considered in turned off of the State. Attempts to turn on the virtual machine fails with the following error:
    
    Cannot lock the file
    
    Workaround: No.

  VMware support for the record said that the patch will update 3, it is known as an intermittent problem. Finally, it happened to me on the 9th attempt.

• VMotion VMs Wit RDM

  People,

  Can you vmotion a VM with RDM LUN inside from one node to another in a cluster on the fly?

  Also, I would like to know if I put the ESXi in maintenance mode, all virtual machines including those with RDM connected gets vmotioned to other nodes in the cluster automatically

  Rahul-

  Hi Rahul

  It is stated in the Documentation that you can use with VM with RDM vSphere vMotion.

  Documentation Center of vSphere 5.5 - on Raw Device Mapping

  With RDM, you can:

  - Use vMotion to migrate virtual machines using raw LUNS.

  
  

  If you use vMotion to migrate the virtual machines with RDM, be sure to maintain Consistent ID LUN for RDM on all participating ESXi hosts.

• 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

• Faced with a failure of OSD task sequence. The failure messages in the end are: failure to file WIM mount (0 x 80070002) & Failed to create media (0 x 80070002)

  Hello

  Faced with a failure of OSD task sequence.

  The failure messages in the end are:

  --------------------------------------------------

  Has no file WIM mount 0 x 80070002

  Cannot create media 0 x 80070002

  CreatTSMedia failed with error 0 x 80070002 details MediaGenerator

  --------------------------------------------------------------------------------------------

  It comes via SCCM 2007 R3 and a version of Windows XP.

  I think 0 x 80070002 means "the system cannot find the file specified."

  But what file?

  How do you determine what the media Wizard is missing to generate this error?

  Is this a driver problem?

  Thank you

• 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!

• 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.

• 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 -.

• SRM with RDM, PRO using DR using iSCSI and FCoE

• 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:

• HA with RDM

  Dear all

  Is it possible HA witch RDM attached VM?

  Thank you

  Scheller

  Yes HA works well with RDM. HA will validate before it restarts the virtual computer if the host is "compatible" or not, in other words is also available on the host RDM, I'll try to restart the VM on.
