• All virtual machines to an ESXi Server ping

  Hi all

  For a project of mine, I need to create a script that asks for the ESXi server host name,

  and after that start ping all virtual machines that are on the ESXi server.

  I tried to do without success up to now.

  Help will be appreciated.

  Thank you!

  What follows is based on the fact that the VMware tools are installed.

  If they are not installed, you could adapt the script to try and ping displayname VM.

  $esxName = "MyEsx".

  Get-VMHost-name $esxName | Get - VM | %{

  $hostnamePresent = $_. Guest.HostName - don't $null

  {if ($hostnamePresent)}

  $pingable = test-Connection - ComputerName $_. Guest.HostName - count 1 - calm

  }

  else {}

  $pingable = $false

  }

  Select - InputObject $_ - the property name.

  @{N = "This Hostname"; E = {$hostnamePresent}},

  @{N = "responding"; E = {$pingable}}

• Large SQL virtual machines running on ESXi

  Hello

  When you decide to run or do not run large SQL VMs on ESXi, what are the points that you take into consideration?

  -How much memory physical RAM more should the ESXi host at least have in relation to the virtual machine? If I have a Go 96 VM on a host of 144 GB, you would use this room for other virtual machines as well? Would you go to bigger hosts? Or that you would a one-VM-host?

  -In a "a virtual machine by host" scenario, is there still a sufficient reasons to virtualize the VM? VMotion, the portability of the virtual machine, adding disks, disks, resizing easy resize memory still reason enough to virtualize this VM?

  -When I add now Microsoft clustering in the equation, killing VMotion and flexibility, it is always possible to virtualize this SQL Server?

  I know how capable ESXi is the delivery of this workload. I have the white papers of performance on HOW to virtualize SQL successfully. My question is above all on: If you...

  It is like arguing about policy; There are people with all kinds of views and a large part of it boils down to personal opinions. Some things to consider;

  (1) you do not mention how CRITICISM (aversion to downtime) is the database. If it is super important, certainly looking to HA or even fault tolerance. This increases considerably resources on a virtual machine.

  (2) even if you use one approach "a virtual machine by host", you must make sure that the availability on OTHER hosts in the case where HA is triggered.  So you have basically two hosts per VM

  (3) in view of the above, and how this intensifies that you get in redundancy, HA and FT, you can compare the cost a cluster HA environment.

  We personally, it is facing a prior work. We went with material in the physical server cluster.  In my opinion, if the server is simply great, but didn't need to HA or FT, then I would consider virtualization it. If she needs these features, the fresh material support worsen significantly. Size alone is not a huge problem, assuming you have the SAN space or storage. I am currently supports environments with virtual machines that are more than 1 TB and will work perfectly.

  I hope this helps.

• List of all virtual machines running on a local storage

  Y at - it a script when it is applied to the virtual center would show the virtual machines that are running on a local storage of an esx host.  We have about 40 esx running on virtual Center host and there are some VM running on local storage that we have to go offshore, but I need a list of these virtual machines.

  If it helps the naming convention for the local storage data store is "exhostname_local".  This is the norm for all hosts.

  Any Advisor.

  It must be Friday

  Try it like this

  Get-Datastore local* | where {$_.ExtensionData.Host.Count -eq 1} | Get-VM -Location $_ | Select Name
  

• Close all virtual machines on ESXi

  Hello

  I'm new in the administration of vSphere. I would like to raise our ESXi servers due to updates, but I've read that you shut down all virtual machines that are on it. You have something better to do then close VMs one? I expect a powershell script, but I have found none so far.

  Thank you

  Kralijir, you can do it from the console GUI.

  In the left pane, select the ESX host.

  In the right pane, click the tab "virtual machines". Now, you can select block all virtual machines here and simply right-clicking them stop all, or make other changes in bulk.

  Some changes via selection bulk require all virtual machines to be in the same State; Turned off the power, power, etc.

  If it works for you, please mark this answer as the 'response '.

• How to count the number of virtual machines on an ESXi server via command line

  I want to know the number of virtual machines running on ESXi. What is the command so that it...?

  "vim - cmd vmsvc/getallvms"

  This order list of the early running of the ESXi Server virtual machine, but I want the number (integer)

  Help, please...

  Thank you

• List of Cluster and the virtual machines running on this group

  Hello

  I am looking for a way to discover all of the virtual machines that belong to a cluster. In other words, I want a list that maps a cluster to all virtual machines running on it.

  In the documentation of the API, I find that "ClousterComputeResouce"has a managed object to "HostSystem" reference. "

  And "HostSystem" is a reference to managed object to the 'VirtualMachine'.

  So I can do it like this: ClusterComputeResource-> ManagedObjectRefence-> ManagedObjectRefence (VirtualMachine)-> whatever_properties_I_need_from_the_VM (HostSystem).

  However, this would cause a lot of ' Vim::get_views"calls within a"foreach"loop." It would be a deterrent to performance as the vCetner in question has ~ 50 clusters and has ~ 3500 running VMs.

  I think this was going to literally kill the VirtualCenter with so many API calls.

  My Question: is there an effective way to find Cluster and their respective VMs in vSphere SDK Perl.

  In vSphere client, we get the tab 'Virtual Machine' when we click on the Cluster and you can see all the virtual machines that belong to this cluster. So I hope that there must be an easier way.

  Thank you.

  Hello

  You don't need the host_view for this action. Why don't you use begin_entity for views of the vm?

  my $cluster = 'cluster1. "

  My $cluster_view = Vim::find_entity_view (view_type-online 'ClusterComputeResource',

  filter => {"name"-online qr / ^ $cluster / I});
  {if ($cluster_view)}
  My $vm_views = Vim::find_entity_views (view_type-online 'VirtualMachine',

  begin_entity => $cluster_view.

  Properties-online ['name']);
  foreach {$vm_ref(@$vm_views) my
  print $vm_ref--> name. » \n » ;
  }
  }

  Hope that helps!

• All virtual machines are dead

  Hi, I discovered today that all virtual machines on my ESXi 4 has been arrested.  There are balls I can check what happened?  4 virtual machines are all CentOS 5.5 64-bit and very lightly loaded (IE TOP shows 0.1 for loading).  There is no more validation of CPU or memory.

  You can... How to do this depends on your configuration... For example, if you use vCenter or not. If this isn't the case, then connect to the host, go to the tab "Configuration", under the heading 'Software', ' Virtual Machine Startup/Shutdown ' select and then click on the 'Properties' link (top right of this window)... This is where you can select the VM power on with the host country, what order they put under tension, or if they "Manual start" value when the host starts.

  If you do the settings on the host computer, vCenter will extract these settings in the configuration... I would suggest testing to confirm that the auto-start settings stick when you vMotion a computer virtual to another host (if you have more than one host) or not.

• ESXi 4.1 upgrade to ESXi 5.5 while all virtual machines and data warehouses

  We have two servers ESXi 4.1.0 348481 (Essentials) and we need to upgrade to ESXi 5.5 for support of Windows Server R2 2012. We intend to use the interactive upgrade. We want to ensure that the virtual machine is preserved. More precisely VMFarm001 where ESXi is installed in the same data store as VMServer1. VMServer1 is our largest server and cannot be migrated to another data store easily because we are not allowed for vMotion.

  The following layout

  VMFarm001

  Dell PowerEdge R710

  Data store:

  Storage1 - 1.36 TB

  VMServer1 - MS Server 2003

  Install ESXi

  Storage2 - 1.82 TB

  VMServer2 - MS Server 2008 R2

  VMServer3 - MS Server 2008 R2

  VMFarm002

  HP ProLiant ML350 G5

  Data store:

  Storage1 - 95GB

  Install ESXi

  ISOs

  Storage2 - 1.82 TB

  VMServer4 - MS Server 2008 R2

  VMServer5 - MS Server 2008 R2

  I have a feeling I'm worried for nothing given that option during the ESXi upgrade and keep the VMFS datastore.

  Thank you

  Yes, that's correct.

  I recently finished the upgrade of lots of stand-alone hosts ESXi 4.1 (with local storage only) to 5.1 and all were successful. The same process applies to 5.5, so you shouldn't have a problem with preservation of VMFS data warehouses (and all virtual machines).

• Run a Windows command on all virtual machines

  Using PowerCLI, is it possible to run a Windows command on all virtual machines?  I would like to hiberbation disabled on all my servers as it is unnecessary and take up disk space.  Running powercfg-h off will do, but I really want to do it on all 200 of my VM.

  I can't seem to find the option in group policy, so I was hoping that this could be an option.

  The above posts are excellent resolutions. Here is another possible approach.

  You can do this with a Powershell script. Something like this should work:

  1. The list of virtual machines:

  SE connect-ViServer here VCenter server name

  $vms = get - VM

  1. If you have installed Powershell and PSRemoting enabled on each virtual machine, run the following:

  $vms | foreach-object {Invoke-Command - ComputerName $_.} Name - ScriptBlock {powercfg - h}

  1. If you have not installed Powershell and PSRemoting on each virtual machine, use WMI:

  foreach ($vm to $vms)

  {

  $vmName = $vm. Name

  (\[WMIClass\] ")
  (' $vmName\ROOT\CIMV2: Win32_Process "). Create ("cmd /c powercfg - h)

  }

  You should probably use the WMI method since it is unlikely that all of your virtual machines have Powershell installed and configured for remote access.

• Virtual machine running on snapshot but there are no spanpshot on the Snapshot Manager.

  Hi all,

  After a backup with VMware Data Recovery failure (error-3960 cannot suspend virtual machine), I have a virtual machine running on snapshot (see attachment) but there is no snapshot on the Snapshot Manager. Is the command to "consolidate" (I have never used this feature) the solution?

  Thank you.

  Marco.

  OK let me explain.

  As the chain of snapshot is not displayed in snapshot Manager, you can correct this problem in two ways.

  1 engage the snapshot command line. If you are uncomfortable in the command line, follow this KB KB VMware: commit snapshots on ESXi host command line if you are not comfortable follow step 2.

  2. create a new snapshot for this virtual machine (this will create a chain of snapshot, and you can see the snapshot in the Snapshot Manager), once the snapshot is created successfully. You can remove the snapshot in the Snapshot Manager.

  Hope this is clear. Let me know if not

• Is no vmdk file, but the script says, all virtual machines backed up Ok!

  Hello everyone;

  Please excuse any lack of details because this is the first time that I write. I've scoured internet for days now trying to find no matter how much detail that could help me solve the problem. I'm new in the world of script ESXi and ghettoVCB.

  My intention is to run several tasks on a schedule. Each type of backup (quarterly, monthly, weekly, daily and multiple) runs at a specific time. The planning section works very well.

  I'm hoping to solve this urgent backup, I should be able to solve reboot.

  Here is the command I use:

  /vmfs/volumes/datastore1/ghettoVCB.sh w /tmp/ghettoVCB-work.multiple f/vmfs/volumes/datastore1/vmlist-Multiple g/vmfs/volumes/datastore1/vmconfig-DataSet1-multiple-l /vmfs/volumes/datastore1/ghettoVCB_logs/ghettoVCB.Multiple_Backup.log

  vmconfig-DataSet1-multiple contains:

  # Multiple backups - rotation County 6

  #

  VM_BACKUP_VOLUME = / vmfs/volumes/Vault2-DataSet1/URANUS/Multiple

  DISK_BACKUP_FORMAT = thin

  VM_BACKUP_ROTATION_COUNT = 6

  POWER_VM_DOWN_BEFORE_BACKUP = 0

  ENABLE_HARD_POWER_OFF = 0

  ITER_TO_WAIT_SHUTDOWN = 4

  POWER_DOWN_TIMEOUT = 5

  SNAPSHOT_TIMEOUT = 15

  ENABLE_COMPRESSION = 0

  VM_SNAPSHOT_MEMORY = 0

  VM_SNAPSHOT_QUIESCE = 0

  VMDK_FILES_TO_BACKUP =

  Vmlist-multiple contains 1 server is listed:

  # List all virtual machines that are backed up several times a day

  HEAT

  The log indicates that the backup was successful - but it has not been the case. Backup size should be approximately 8 GB. However, when you look at the output folder, only the following files are here:

  
  

  HEAT.vmx

  STATUS.ok

  Question is now - where are the vmdk files that should be present?

  Output (-d debug) can be found here: http://pastebin.com/hMGphTL3

  So, here is what I observed:

  When you run the script, the snapshot only takes a few seconds to create and delete then. I'm seeing happens on the list of the tasks of vSphere Rencent (screenshot attached).

  If I create a snapshot manually - it will take much more time to create and delete a snapshot. The difference here is 6 minutes, and 4 seconds using the script create a snapshot manually.

  So my presumption is that he is not actually create the snapshot, although vSphere said it is being created. So why is it the case?

  Help, please.

  ADDENDUM:

  If I run the following:

  ./ghettoVCB.sh m HEAT

  The backup is successful.

  Your said he clearly did not config file to back up all files hard.

  VMDK_FILES_TO_BACKUP =

  I expect to see something like this if you want all the hard files

  VMDK_FILES_TO_BACKUP = "all".

• Setting Options such as Hotplug for all virtual machines

  Hello!

  I have about 5 esxi hosts 5 and about 50 virtual machines

  Unfortunately I forgot to select some options like activate the plug-in memory and cpu hot

  I have 2 questions

  1 can I do this without turning off the machine

  2. How do I make a few options like this (or for example another option as vmtools update during the feeding cycle) for all virtual machines in my environment

  It's too much time to go to all virtual machines and turn them off and turn on these options

  Thank you very much

  These features must be enabled before the virtual machine is running.  So, you will need to turn them off and then use something like powercli to enable the features and turn them back on.

  Here is an example on how to do it with powercli: http://ict-freak.nl/2009/10/05/powercli-enabledisable-the-vm-hot-add-features/

• All Virtual Machines is not responding

  By 2-3 weeks are all the virtual machines on our ESXi Server block. I can connect to the host using the vSphere Client, but cannot perform any actions. I can't restart the host, check the status of the material or any other thing. Any of you VMs can be found either. Still, the only way to get the server up and running is to push the power button and bring it all the way. Once it is restarted it there any errors anywhere, and everything seems normal. This problem happened on 2 of our ESXi hosts, are both Dell PowerEdge R310 server that are 5 months old only. Any thoughts on what could be the cause, or how to solve it?

  Well, this is a really end followed, but which finally solved the question replaced our cards RAID PERC 6i with cards RAID PERC H700 (w / BBU). We did it since (more than 3 years now!) we did not have these problems at all.

• VCenter Server installed as a virtual machine within a ESXi servers it manages?

  Hi all.  I'm new in the world of VSphere... still in my evaluation period.

  I have only a single ESXi server running at the moment but plans to add a second later for high availability, vmotion, increase general capacity, etc.  They are / will be ESXi running on the internal storage and the virtual machines running on a shared SAN.

  Today, I installed VCenter Server 4 on a server at bottom of range/Office that I was carrying around running XP Pro x 64.

  As I was installing I read the guide installation and to my surprise, it seems to recommend that I have installed VCenter Server 4 as a virtual machine on my ESXi host.

  Now maybe I just spent too much time setting up my without new Lefthand requiring a 'witness' during the failover of one SAN to another... but I was under the impression that VCenter Server is not designed simply to host configuration, but is also designed to act as a 'witness' or to take account of quorum whenever a failure scenario occurred on one of my ESXi hosts.  I also noticed the VCenter Server features of a port "heartbeat", which I suppose one would use for the ESXi server heartbeat, but perhaps it is used for "connected mode" with other VCenter servers (I was intending to use only one since it is a small scale installation) I also felt that it would be useful enough to restore a damaged or shot ESXi host.

  So my question is, if my ESXi host dies and it is where I have VCenter Server installed, then high availability will be unable to work?  I guess there are going to be other issues with me unable to access VCenter Server while I have an ESXi host shot, too, as a greater difficulty to get the ESXi up?

  Maybe I'm wrong understand the purpose of the VCenter server... maybe it's not something that's necessary for HA, recovery, etc. and acts only as a configuration tool until something is wrong?  Or maybe I misunderstood the installation guide and they recommend only installing VCenter Server on an ESX box... they don't want this ESX box to be part of the group that manages the server?

  Finally, if indeed they recommend I install this on a ESXi host manages... would I ideally be install this for local storage on the server (where I installed ESXi) or on the SAN (where all my other virtual machines are installed)... or is it just personal preference?

  Thank you!!

  When you add hosts an active hemagglutinin vCenter cluster HA agent is installed on it.  This agent is what is actually the HA.  While necessary to add new hosts in a cluster and configure some specific parameters of vCenter vCenter's agents HA are self-sufficient and can handle HA failover so vCenter is offline.

  You must install the vCenter VM on SAN storage, so that he can use the vMotion, sVmotion, DRS, HA, functions etc. that require a SAN.
