• Virtual MSCS Cluster physics to physics of MSCS Cluster passing

  I have a MSCS Cluster of SQL running on Windows Enterprise Server 2003 2000. I need to move nodes in this cluster as a virtual machine. I have searched using a variety of terms and read a few large documents, including vi3_vm_and_mscs.pdf, but I have not found a single shot high level or low level description of the steps that must be taken.

  So far, I have has all the cluster resources to node in the cluster physical and used Converter P2V Enterprise the other node. It worked well. I must now get the quorum drive and other shared drives seen by the new virtual machine. I know that this will require of RDM, but I wonder if there are traps, that I should be aware, or if there is a white paper or a best practices document detailing the process of virtualization of a node of an MSCS cluster direct.

  Any help is greatly appreciated.

  You will have to:

  The LUNS of existing data/quorum at the zone ESX Server

  Rescan your ESX storage adapters

  Stop the virtual machine, you want to add the ROW

  Add a disk, raw device mapping, physical compatibility mode, select the Lun you zoned in, find the SCSI ID, select 1:0. This will create a new SCSI adapter

  Change the new physical to be bus SCSI adapter shares

  Start your virtual machine, and you should be able to see the new drives

• 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.

• Number maximum official virtual computers Win2k8 supported in a MSCS cluster

  Please can someone point me on the official document or an answer to the following questions:

  • What is the maximum number of Windows 2008 virtual computers based supported in a MSCS cluster (based on vSphere 4.x cluster)

  • more generally, what is the maximum number of Windows 2008 virtual computers based supported in a MSCScluster (based on any cluster ESX/ESXi)

  All the documentation I've seen only speak of 2 nodes (and other sources mention that only 2-node MSCS clusters are supported by VMWARE), but I want a definitive answer to VMWARE or documentation that specifies the maximum number of VMs of Windows 2008 that can be in a MSCS cluster hosted on ESX/ESXi clusters.

  Thank you.

  The documentations are correct. Even though you may be able to create a cluster with more than two nodes, the supported limit is 2 knots.

  Take a look at MSCS documents to http://kb.vmware.com/kb/1004617

• How to make a submission even as RDM for two Virtual Machines

  Hi I have a question.

  We have a server ESX4.0 with two Virtual Machines running on it. I presented a 100 GB of SAN storage to this particular ESX host, this storage space must be shared between two virtual machines as RDM.

  But when I add this storage on a computer virtual as RDM, it does not allow me to present the same storage another VM, of RDM is displayed under the name hidden. Is it possible to do so.

  Kind regards

  Khurram Shahzad

  This is only possible with the MSCS clustering functionality.  With the same logic unit or disc number to multiple hosts without clusting will damage the volume of data / as the new system will try to initialize the disk.

  Your RDM may also need to be in virtual compatibility mode to do this.

  The guide of vmware on clustering with MSCS and there should be information about it.

• Cold migration of MSCS cluster node clients?

  Work on the establishment of a MSCS cluster on 2 hosts.  The hosts are the ESXi 5.5 build 1892794.

  My shared disks are RDM compatibility mode physical that I have attached to a second SCSI controller in physical sharing mode.

  My cluster validation wizard is successfully completed.

  However, if I turn off the guests, everyone migrate to a different host (with FC to the RDM LUN connectivity), turn on and then run the cluster validation Wizard error e/s disk wizard reports on tests of arbitration and failover.

  I learned that when I see these mistakes I can unsubscribe the VMs, detach the storage from the host, restart the host, attached storage, re - save virtual machines, and then validation is successful.  However, it is a bit complicated and if I say lose a blade and need to put one of my guests node elsewhere, I want to do without the time and hassle.  Is this possible?

  I know vMotion is not supported with the physical bus sharing, but this ban applies to cold (power off) so migration?  Or is this an indication that I screwed up my configuration?

  Any thoughts would be great.

  Thank you

  Here's what VMware has sent:

  =======================

  -A virtual machine that has a ROW in a MSCS cluster connected in physical compatibility mode cannot be vMotioned.

  -Even if you do a cold vMotion (stop the virtual computer, then vMotion), the ROW could be detected as vmdk and you may need to remove
  She and present it back or re - enter as you mentioned.

  -Best practices recommend Vmware are that - before the migration, remove the ROW of the virtual machine, and then migrate the virtual machine. Once the
  VM was vMotion, then you can attach the RDM to the virtual machine.

  Unfortunately there is no work around on this
  scenario.

  ======================================

  So I guess the cold, you can migrate the MSCS cluster nodes but sometimes it does not work quite as well and so its best to remove the ROW before migration cold.

  Thanks to all who have posted!

• Quorum configuration - option 'Add an existing drive' and no Quorum disk appears

  Hi all..

  I'm MSCS Faiover 5.1 of vSphere clusters management document and everything went well till I myself am page 24... Add the Quorum disk to the second physical host.  He mentions I should add existing hard drive, then select RDM quorum I added to the first host.

  When I go to select the disc, it does not appear in the data of the list store... is there a setting I'm missing?  All fine on the first host mapped RDM, but none are appearing for me to add on the second host.  I don't know that it's a trivial config, I forget, but cannot understand where he might be.

  Any help would be appreciated...

  Thank you very much

  When you add a logical unit number to a virtual machine as a RDM, ESXi will create a hard of mapping file in the folder of the virtual machine (default). For the second virtual machine, use "Add an existing virtual disk" and navigate to the folder of the first virtual machine, where you will find hard to mapping files.

• He had to set multiple RDM on a virtual machine

  Hello geek,

  I'm writing a powercli script that attach multiple RDMs to a virtual machine. I google and a lot of scripts I received yet, but it's not obvious.

  I thought to create the csv file containing all the canonical of the RDM and importer names that helps import-CSV, then no idea how to go further.

  New drive hard cmdlet will join but how to attach multiple of RDM?

  Please answer

  Thank you

  The UseCulture switch takes care of different separator characters that exist in different locales (locale).

  Get-Help Import-Csv-parameter UseCulture

  The character '%' is an alias for the ForEach-Object cmdlet.

  You can check by doing a

  Get-Alias %

  The Get-Help and Get-Alias cmdlets are very useful when you use PowerShell.

  Another useful is the Get-Member cmdlet, which displays the properties and methods on an object.

• Reboot ESX with MSCS Cluster nodes

  Hello

  I have an ESX Cluster that must be restarded. This host cluster to a MSCS Cluster (without recommendations affinity VMWARE DRS...).

  What is the best practice?

  -Keep maintenance mode, as the other VMS running vmotion or,

  -Set the DRS affinity as soon as possible and the node of MSCS Cluster stop when necessary (only comments stop or other actions to do before?) or,

  -Any other idea?

  Thank you

  Should not able to vmotion for DRS wikll MSCS cluster node does not work - strting with the ESX host that has the standby node place it in Maintenance mode and manually knew node MSCS nodes - restart the host ESXi get node maintenance - once it is up and the lcuster MSCS is stable - the main failover node MSCS and shute to the bottom of the virtual machine - place this host ESX to Maintanance mode allowinf DRS to evacuate VMS running - restart the ESX host brings the VM MSCS back up and replace the workload in this node MSCS.

• Cannot add space on a virtual drive?

  I try to add space on a virtual disk existing on one of my VM file servers so that I can extend this partition on the guest OS and vSphere gives the following error:

  Current disc size is 1000 GB and try to add 250 GB of this existing drive.  I was able to do this in the past on this same server on the same drive in the past.

  

  I haven't restarted this server yet but wanted to see if anyone else has had this problem.  This works on other VM servers, I have as I have tested a few minutes ago is specific to that server VM.

  Hi Pyr0TeK,

  Maybe you have reached the maximum size of the file. You can take a look at the following kb.

• How to re - add RDM (physical)

  Hi all

  Had some problems of migration of a virtual machine to another host - turned out be because she have the RDM (physical) disks. If the virtual machine and it migrated offline and has been properly migrated - but now I could not power on it, because he complained of not found disk. I therefore change the VM and removed the RDM (leave records) so that I could then add again. However, I could not add RDMs now because it is grayed out (from the add new hard drive Wizard).

  When I looked at the data store, I see the RDM files (pls see attached screenshot)-it is, how to add them to the virtual machine?

  Thank you very much.

  Since the new host are you able to see Raw LUNs? The RDM is essentially a special VMDK is nothing else that a pointer to the RAW LUN, and if the new host cannot see the raw LUN, so won't it be able to access it from the VM on the host - new
