• LAN-Free backup of snapshots VMDK of ESX Cluster

  My intention is to perform a backup outside shots VMDK of ESX Cluster to VCB Proxy Server LAN.

  I have a scenario where I have 3 ESX servers with 3 x 800 GB LUNS in a storage group separate on a CX 310 SAN box. The Ids., (HLUs) host these 3 LUN LUN are 0, 1, and 2. All these three LUNS is a VMFS volume each on the ESX Cluster and all three LUNS are visible to all the ESX servers.

  I have a physical host that boot from SAN (the same box of CX 310 SAN) and this host will be designated as the VCB Proxy Server.

  Now, I'm going to add a 1 TB LUN to the storage group as the LUN 4 ESX servers and the Id., (HLU) host LUNS for this one will be 3. This logic unit number will be added as the 4th volume of the cluster ESX VMFS. It will also show all three ESX servers in the Cluster.

  I'll create a Windows VM 'VM2K3' on ESX Server 1, and I intend to add the volume (1 TB) entire VMFS 4th as "D:\". "drive"VM2K3 ". I'll share this disc "D:\". "and it will be mapped as drive"T:\ ". "on the VCB Proxy Server. This disk 'T:\ '. "will be the target for the storage of the VMDK to snapshot backups, in a compressed format. I use VizionCore vRanger software connection to this effect on the server VCB Proxy itself.

  Question 1.

  This scenario will provide the backup off LAN of VMDK instant?

  Question 2.

  In the case of a failure full 1 ESX Server, VMotion will be or a manual movement of the virtual from Windows "VM2K3" machine would affect the LAN-Freee of instant VMDK backup? If so, how will this affect and what will be the impact?

  Question 3.

  The "C:\". "Logic of the VCB Proxy unit number will be a 30 GB SATA LUN and the total size of the RAM on the VCB Proxy Server is 8 GB. The ability to drive "C:\". "30 GB will be sufficient to make faster given the fact that I have about 45 VMs at this point in time?

  Any help or suggestion or two in this case would be very useful.

  Hello

  A physical machine cannot directly access a VMDK in a VMFS. There may directly access LUN, that LUN could then accessible by a VM with RDM or virtual RDM mode. But why would you do it is really beyond me.

  The VCB Proxy running W2K3 and you present all your VMFS volumes (make sure that you don't have a letter assignment drive automatically enabled when you make this presentation). See http://www.vmware.com/pdf/vi3_35/esx_3/r35/vi3_35_25_vm_backup.pdf for assistance with this.

  VCB proxy then read this VMFS and copy data from it to your T:\ drive (MON).

  Remember that no two hosts can access the same logical unit number unless you use a clustered file system.

• VMware DRS and VMware HA

  I'm allowed to use VMware DRS and HA but I'm not familiar with what exactly they can do for me and how they might relate to Vmotion.  I turned on my 2 hosts of vmotion, but I guess my virtual machines do not automatically move from one host to another one grave host fails, until it is completely configured.   Could someone give me a quick description and point me in the right direction on how I can use?

  I have licenses for the company for the full suite of vsphere.

  DRS - distributed Service Resouces

  This process will recommend to move a virtual machine for performance reasons.  This can be set to automatically move virtual machine.  We have defined it this way and it works very well.  VM move on their own see and at night.

  HA - high availability

  If a host goes down, this service starts the VM who have been on this subject, to another host automatically.  The virtual machine will be turned off unexpectedly well.

  FT - fault tolerance

  This feature is introduced in ESX4 and keep a copy running on another host.  If the primary host fails, the other takes over with no downtime.  It is currently limited to VM with one vCPU however.

  DRS and HA are configured in the properties of a Cluster.  If you do not have a cluster, right-click on a datacenter in VC and create a cluster.  Move the hosts in the cluster.  Drag and drop works fine.  Right-click on the cluster, and then select both.  Once activated, you can configure the DRS and HA.

• Penetrating VM from ESX Cluster stand-alone ESXi Server

  I get an error trying to move a virtual machine of cluster VI in a standalone ESXi Server, someone had a bit of luck this?  I tried the following: Get-VM-name "CO-WS-TEST1" - location (Get-VMHost "CO-WS-TEST1"). Move-VM - Destination (Get-VMHost "CO-VM-TEST2") where CO-VM-TEST2 is a stand-alone ESXi server and CO-WS-TEST1 is in an ESX Cluster with VI.

  I get the following error:

  Get-VMHost: 2009-04-13 13:08:08 Get - VMHost VMHost with the "CO-VM-TEST2" name not found, using the specified filters.

  On line: 1 char: 60

  Thanks in advance for any help you can give me.

  What is ESXi system managed (for example with a non-free full license) by your vCenter?  If this isn't the case, then you can not make a gesture like this.  You can probably fake it with enough script and help of some external tools to make disk copy.

• VMware DRS / virtual machine options

  I would like to extract the vmware drs / VM options via powershell.

  Does anyone know a way to do it?

  OK, I understand.

  The behavior property is apparently not valid if the Enabled property is set to $false.

  And since I have not all the guests where the DRS is set to "disabled" I didn't notice that before.

  This update script should do the trick.

  $cluster = Get-Cluster | Get-View
  Write-Host "Default DRS behaviour : " $cluster.ConfigurationEx.DrsConfig.DefaultVmBehavior
  foreach($vmConfig in $cluster.ConfigurationEx.DrsVmConfig){
       $vm = Get-View -Id $vmConfig.Key
       if(-not $vmConfig.Enabled){$state = "Disabled"}
       else {$state = $vmConfig.Behavior}
       Write-Host "`t" $vm.Name $state

• To VMs in Server VM ESX cluster

  Aloha,

  I have a host running six XP SP2 virtual machines on VMWare Server 1.0.5. I want to migrate my ESX cluster.  What is the easiest way to do this?

  Mahalo, Bill

  You do not need the enterprise version, you can use the free version.

  You install Vmware Converter on the server that has VMware Server installed, then you can either do convert the 'physical' machines which are virtual machines or turn off the VMs system and get a Converter to convert the VMware ESX Server VM files

• VCenter Server first to 5.5.0U3b update and later update of VMware ESXi ESX / will I have problems?

  Hello

  have trouble when I first updated my signature single vCenter Server and later update my vSphere hosts?

  A vCenter Server Version 5.5.0U3b should be able to manage vSphere Host Version 5.5.0 GA, right?

  Kind regards

  Roland

  The vCenter Server 5.5 update 3 b can manage VMware ESXi ESX release GA to 5.5 5.5 update 3 b, take a look: VMware product interoperability Matrices

  BUT, according to the interoperability matrices and vCenter Server 5.5 update 3 release notes, VMware strongly recommends you upgrade your hosts to 5.5 update 3 b, see:

  What's new

  • Update Support for the SSLv3 Protocol is disabled by default
    Note: In your vSphere environment, you must update vCenter Server vCenter Server 5.5 update 3 b before the update to 5.5 ESXi ESXi update 3 b. vCenter Server will not be able to manage 3B ESXi 5.5 update, if you update ESXi before update vCenter Server to version 5.5 update 3 b. For more information about the sequence in which vSphere environments must be updated, see KB 2057795.

  • VMware strongly recommends you update ESXi hosts to ESXi 5.5 update 3 b management of vCenter Server 5.5 updated 3B.

  VMware does not recommend the reactivation of SSLv3 because of the vulnerability of POODLE. If all you must enable SSLv3, you must activate the SSLv3 Protocol for all components. For more information, see

• How to migrate VRM to another ESX/cluster server

  We have our VRM and VR servers running with vReplication in an ESX cluster.  The network manager has decided to split the ESX server and create a new cluster for our servers, leaving the old cluster and ESX server environment from the view.  I was able to migrate the VR server without any problem, but receive a warning when you try to move the VRM.  How is it best to do it without having to stop the replication and recreate all (that has been no joy for us)?

  Hello

  Safely, you can migrate the VRM machine or use vMotion.
  Make sure you remove the VRM from the inventory of VC machine, as in this case, the configuration of the OVF environment will be lost.

• Question of VMWare Fusion

  I currently use Parallels Desktop and have a question about VMWare.

  VMWare Fusion provides any software to the virtual machine which is necessary for integration with OS X?

  (Parallels made - self-installing Stardock MyColors on Windows VMs without opportunity to decline - have to uninstall later)

  I was wondering.

  The only VMware Fusion software will install automatically when creating a Machine virtual Windows is VMware Tools and it usually automatically starts, but can usually be cancelled although unless you try to isolate completely the host comments then I'd let VMware Tools installed.

• Memory for the ESX Cluster stats | Total, Avail, allocated, used...

  Before going out and trying to write a script that does the following, I wanted to know if someone has already written something similar:

  • Collect the total amount of RAM in each
    ESX cluster less the total RAM allocated to virtual machines in the cluster.

  • For example, if
    32 GB of RAM is available in a cluster and there are four 1 GB VMs and virtual two 2GB computers running, then we have 20 GB of RAM remaining to support 20 1 GB VMs.

  • Pull the memory allocated quantity to the VMs system compared to the amount actually used as a measure as well.

  Thank you

  I don't know if you need to calculate the memory available to the virtual machines like that.

  Not all memory in a cluster is available for running virtual machines.

  And a virtual machine does not always all of the memory that you have configured with the memory available to the cluster.

  And of course, this changes over time depending on the activity of the virtual machines.

  Take a look at the total on the cluster by vm and check if the script there is no more sense to what you try to get.

• Questions about vmware high availability

  Dear all,

  I am new in this area, we intend to deploy vmware 5 in our environment by using the HA, I am a student in this regard. I have a few questions about this, I need assistance by experts in this field:

  -J' read the vmware network redundancy is strongly recommended for the configuration of vmware HA, but I haven't fully?

  -When vmware HA is configured and there are two hosts in the cluster, now when creating a new machine virtual, I need to specify under which host this new virtual machine must reside OR the HA feature will automatically decide on that?

  -When vmware HA is set up and I have two hosts in cluster, a host processors 4physical and 8 GB of RAM, the other host is also even have 4 physical processors and 8 GB of RAM, so for me which are the sets of resources will be presented? I will be display individually for each host resources when you create a new virtual machine, OR I will be presented with a SUM of resources 1 + 2 host resources to play?

  -Is it possible that I assigned 4 vCPU virtual machine and 4 GB Mem and it uses little resources from host 1 and few resources to host 2, as 2 vCPU to host 1 and 2 GB and still host 2vCPU 2 and remains 2GB (given that I am presented with the SUM of the cluster as mentioned in my second question resources)

  -J' read operating system failure when in vmHA particular VM will be restarted on the same host it resides, that means? If the BONE broke down, then when new virtual machine starts, it will be also having fallen copy of OS? I mean how this new machine will be launched, it's a copy identical secondary virtual machine crashed?

  Waiting for your help.

  Kind regards
  Jocelyn

  OK, consider cases that I am only using HA and no DRS, in this case I need to specify under what host to run VM?

  I read the first question again, then please, let me make this clear. When you create a new virtual machine, you must always specify a host and storage.

  Initial investment (when you are powering on a virtual machine) is a feature of the Drs without DRS a virtual machine can only be migrated to another host manually or with the virtual machine shut down (cold migration) or using vMotion (if allowed).

  But because of an event leading to the crash of the OS reboot also not solve the problem, correct me if I understood? This is also true for FT?

  You're right, HA can restart only a virtual machine. If there is a serious issue that causes the BONE invited to plant that regularly, this is not enough and you have to solve the problem manually. FT cannot resolve as she makes it "mirrors" the guest to another host, so it will also reflect a BSOD.

  Yes, FT has still some limitations. However, there are use cases where availability is important and FT is designed to ensure continuous availability in the event of a crash the host.

• ESX 3.5 Update 5 versus question 4.1 VMotion ESX

  Good afternoon

  I hope it's a small question, I'll try to be concise.

  Basically I have an instance of Virtual Center 2.5 Enterprise (original version) with two ESX 3.5 knots (original also build... don't read any updated). DRS and HA are enabled.

  We started to exceed two knots (about 40 guests between them) and we recently ordered two new servers. Since it is several years since our first installation, we cannot buy the same materials. My understanding is that ESX 3.5 and earlier did not play really well when you introduced different hardware (servers) in a cluster. I've heard say that ESX 3.5 Update 5 (besides being current and taken in charge) remedies this problem. Is this true?

  Can I update my current environment ESX 3.5 update 5 and updated to Virtual Center 2.5 update 6 and then introduce some servers intel based more recent (but similar) in the cluster without any problems (ie. Invited VMotion between all ESX 4 nodes).

  Upgrade to 4.1 is more than I can swallow in the next few days, as they would result at the end of next week. I guess I can go down the licensing of two new ESX Server (ESX 4.1 licenses have been purchased for these new servers).

  Thank you

  TMR

  Am I right to assume that, in this perspective, ESX 3.5 U2 and ESX 4.1 will be will be the same in terms of CPU and EVC baselines (in other words, 4.1 has an advantage here).

  Yes, it's a safe assumption.  VCA Mode automatically applies the best option of compatibility possible for you, regardless of the version of ESX.  It is strictly for the CPU compatibility.
