• List VMFS version and block size of all data warehouses

  I'm looking for a PowerShell script (or preferably one-liner) list all with version number data warehouses there VMFS and their blocksizes.

  I am a novice PowerShell and ViToolkit, but I know how to do the following:

  I can list all data stores that begin with a specific name and sort by alphabetical order:

  Get-Datastore-name eva * | Sorting

  Name FreeSpaceMB CapacityMB

  EVA01VMFS01 511744 81552

  511178 511744 EVA01VMFS02

  511744 155143 EVA01VMFS03

  EVA01VMFS04 511744 76301

  301781 511744 EVA01VMFS05

  etc...

  I can get the Info for a specific data store with the following commands:

  $objDataStore = get-Datastore-name 'EVA01VMFS01 '.

  $objDataStore | Format-List

  DatacenterId: Data center-data center-21

  ParentFolderId: File-group-s24

  DatastoreBrowserPath: vmstores:\vCenter-test.local@443\DataCenter\EVA01VMFS01

  FreeSpaceMB: 81552

  CapacityMB: 511744

  Accessible: true

  Type: VMFS

  ID: Datastore-datastore-330

  Name: EVA01VMFS01

  But that's all as far as my knowledge goes.

  Someone out there who could help me with this one?

  This information is not available in the default properties of the DatastoreImpl object.

  But this information is available in the SDK object called a data store.

  You can view these values like this.

  Get-Datastore | Get-View | Select-Object Name,
                                      @{N="VMFS version";E={$_.Info.Vmfs.Version}},
                                      @{N="BlocksizeMB";E={$_.Info.Vmfs.BlockSizeMB}}
  

  If you are using PowerCLI 4.1, you can check with

  Get-PowerCLIVersion
  

  Then, you can use the New-VIProperty cmdlet.

  Something like that

  New-VIProperty -Name VMFSVersion -ObjectType Datastore `
       -Value {
            param($ds)
  
            $ds.ExtensionData.Info.Vmfs.Version
       } `
       -BasedONextensionProperty 'Info' `
       -Force
  
  New-VIProperty -Name VMFSBlockSizeMB -ObjectType Datastore `
       -Value {
            param($ds)
  
            $ds.ExtensionData.Info.Vmfs.BlockSizeMB
       } `
       -BasedONextensionProperty 'Info' `
       -Force
  
  Get-Datastore | Select Name,VMFSVersion,VMFSBlockSizeMB

• simple script for the list of all data warehouses properties

  I searched a lot of scripts to get information about my data stores. I can quickly export most the properies of that I need right to a csv file vCenter. A flagrant lack room is the 'space Proviosoned' display of list of data store. I look at the properties of each data store to see this information. Y at - it a script that can get this information?  For this script, I don't reallt care about the news at the virtual machine level.

  Until they solve this problem, you can use something like this

  Get-Datastore | where {$_.Type -eq "VMFS"} | Select Name,
         @{N="Status";E={$_.Extensiondata.OverallStatus}},
         @{N="Device";E={$_.Extensiondata.Info.Vmfs.Extent[0].DiskName}},
         @{N="Capacity";E={"{0:f2} GB"-f ($_.CapacityMB /1KB)}},
         @{N="Free";E={"{0:f2} GB"-f ($_.FreeSpaceMB /1KB)}},
         @{N="Provisioned";E={"{0:f2} GB"-f (($_.ExtensionData.Summary.Capacity - $_.ExtensionData.Summary.FreeSpace + $_.ExtensionData.Summary.Uncommitted) /1GB)}},
         @{N="Type";E={$_.Extensiondata.Info.Vmfs.Type.ToLower() + $_.Extensiondata.Info.Vmfs.MajorVersion}},
         @{N="Last Update";E={$_.Extensiondata.Info.Timestamp}}
  

• Great move VM to new data warehouses

  Read some of the other discussions on this topic... I have a slight twist... can someone offer some guidelines\options on the best way to move a very large virtual machine

  starting from a NetApp array to an array of EMC VNX.  The virtual machine has 4 discs - including 1 + to 2 each and is currently running on an ESX 4.0 host.  We want to move the

  warehouses of data and comments to a new host ESXi 5.  Can be 2 steps if necessary.  No downtime will be difficult and should be kept to a minimum.  I used vMotion

  and the converter.  A test of vMotion generated a complaint of block size.  Converter is very slow and often times out.  If the prompt can be turned off, I can use the data store

  browser to move the. VMDK, then the .vmx unregister\re-registry.  Slowly perhaps, but should be better than the converter.  Unfortunately, the 4 discs are all separate data storage

  and therefore do not reside with the dtatastore containing the .vmx.  Can I still do this by changing the .vmx to point to the new locations of disc?

  The reason why I try whether the Storage vMotion is possible, is mainly to avoid outages. With ESXi 5 host that has access to all data warehouses, you can storage vMtotion the power VM, VMFS versions no matter what and block sizes. However, keep in mind that migration between different block sizes is slower than the migration with between the warehouses of data with the same block size.

• Script to find virtual machines on data warehouses that begin by...

  I'm looking for a script that will list all VM on specific data with the initial T1SDX1 letters warehouses. I tried to use a certain liners, I found, but they do not seem to work. Here's what I'm not, but it does not list the VM.

  Get-Cluster "Test Cluster" | Get-vm |?{($_.extensiondata.config.datastoreurl|%{$_.name}) -like "T1SDX1"}| Export-Csv "H:\Excel_Reports\vms_on_whatDS.csv"
  

  I tried to use the same command - and -contains the command. Both show no results. I tried a single line, I found here, but it signals a TON of data I don't need and does not even get the info, I need.

  Get-Cluster "your_cluster"|Get-vm |?{($_.extensiondata.config.datastoreurl|%{$_.name}) -match "^T"}
  

  In fact, I found an old script I used who shot all s VM on all data warehouses. It works, I'll just filter across the worksheet.

  Here's the script if anyone cares or she wants:

  $Today = (Get-Date -Format "yyyyMMdd-HH.mm")
  $vcenter = $defaultVIServers
  $report = Get-Datacenter | Get-Datastore | Foreach-Object {
      $ds = $_.Name
      $_ | Get-VM | Select-Object Name,@{n='DataStore';e={$ds}} |

• Assessment vCOPS 5.7.1 - did they add a way to exclude specific data warehouses?

  Hello

  I tried vCOPS in the past and I know that this was not possible.

  I just started a trial now, but I still want to exclude all data warehouses and a couple more which come from a file server that is always 99% full. These data warehouses are not used for virtual machines and shouldn't affect calculations in vCOPS.

  Is there a way to exclude the calculations? Thank you.

  Put all your data warehouses in vCenter the in a folder called "LOCALS" (or something else you like) - this folder will also be known by the VCOPS (may take 5 minutes). Then in VCOPS create a new strategy and clone of "Ignore these objects." On the page of the association take place 'record' and add your folder "INHABITANTS". Check 'current effective policy', it must be on "ignore objects.

  Now, whenever you add a host to vCenter, make sure you put this local data store in the right folder "INHABITANTS". This way you will have exclude them calculations.

• VMDK, vmfs, san, VM, mulitple volumes and data warehouses.

  Hello

  I'm in the middle of the creation of a MV for a windows server which will have some data (about 10 records about 5 TB) file sharing. I find a better one how to create this virtual machine with a correct sizing of the data store, number of data to use store and the number of volumes must span the store data or best recomondation.

  I don't think not vmware support 5 TB of data in the near future, max is less than 2 TB, so I put all data warehouses in a single 5 TB volume or multi-volume 1 TB, 2 TB, 2 TB, and options create the virtual machine with 6 disks (C = 80 GB, 1 TB = D E = 1 to, F = 1 to, G = 1 TB and H = 1 TB).  All my files are less than 1 TB in size and will be will not develop more than 1 TB. Due to the limitation of size of data store.

  I'm looknig for some best practice, expereimented or recomondations solution. Should be an easy management of the virtual machine, an easy migration between the host migration easy with data warehouses or volumes, snapshot to replicate or volume volume, etc... This virtual machine is implemented with cluster.

  Thanks in advance.

  I suggest that you set up a small test and storage vMotion for your self. Understand the limits of Storage vMotion

• Get cluster data warehouses in VC

  Hi all

  I've been trying to write a code that lists all data warehouses in use by each cluster but little progress with it (I know that data warehouses are not a property of the bunch and I need to interogate each vmhost cluster for the info to store data but imreally+ bad)... Ideally I am looking for a similar to the following output in a CSV file:

  CLUSTER NAME DATASTORE NAME NO OF VMS CLUSTER DATASTORE DATASTORE USED SPACE FREE SPACE DATA STORE CAPACITY

  clustertest1 new 88 150 GB 100 GB 50 GB data store

  clustertest1 another datastore 88 70 GB 10 gb 60 gb

  Has anyone known this before - or even something similar?

  Any help would be appreciated.

  See you soon

  This should get you.

  $report = @()
  
  $clusters = Get-Cluster | Get-View
  foreach($cluster in $clusters){

• find the total size of the VM on specific data warehouses

  Hello

  PowerCLI guru, I'm not...

  I'm just using the following to get the total size of the virtual machine.

  Get-vmhost < host name, host name >. get - vm | Select-Object Name, UsedSpaceGB

  The problem is some of these VMS are on 15 k drive and some are over 10 k drive, is there a way to add the data store name each virtual machine is located at the exit. Seeing the data store name that I can know easily what typre of disc it is average.

  Currently, she is just out

  vmname size

  -----------        ------

  ABC 123

  Here you are:

  vmname datastore vmsize

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

  ABC xyz - 567 123

  Thank you

  The following PowerCLI script you will show the name, data warehouses and space used for all virtual machines:

  Get-VM | Select-Object -Property Name,
  @{Name="Datastores";Expression={
    [string]::Join(',',($_.DatastoreIDList |
      ForEach-Object { Get-View -id $_ |
      ForEach-Object {$_.Name}}) )
  }},
  UsedSpaceGB

• ESX host managed by VirtualCenter servers all see the same SAN LUNS / data warehouses

  Scenario of

  I have two separate deployments of VirtualCenter (in the same physical location) VCA and VCB with each deployment management 5 x ESX hosts (10 in total).

  All 10 hosts are allowed to look at the same SAN LUNS / data warehouses?

  Or I have to isolate five VCA hosts and five guests to their own SAN LUNS VCB / data warehouses?

  Basically, we have our direct environment and we are on the beta program for VI4.

  I want to turn off a virtual machine in the direct environment and then pull it out of the inventory.

  Then I want to go the VI4 Beta and browse the data store and add this virtual machine to inventory.

  These two environments may see the same LUNS / data warehouses.

  I did and it works however I want to make sure that it is an approved practice.

  You can do that normally without any problems. Even if the virtual machine is in a different datacenter inventory and there Powred-Off. You can map the logic unit number on the VI4 and add to the inventory of the VI4 another host.

  Recently, I did this practice to migrate from host with virtual machines in a different subnet to the host who knows the same setting SAN LUN in the other subnet.

• 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).

• Need a script to list all virtual machines on specific data warehouses

  I am trying to find a way to list all virtual computers on specific data warehouses. I use vSphere 5.1 and so far I got this:

  Get-Datastore. where {$_ .name - like ' * XXX * ""} | Get - VM | Select name, @{N = "Datastore"; {E = {Get-Datastore - VM $_}} | Sort name | FT - one

  This kind of work, but it would be perfect if I got this:

  -Group data store

  -Unique virtual machines (VMS to report only to the data store where the VMX)

  Any help appreciated.

  I relied on the fact that the first in the list would be the data store that holds the VMX, which apparently is a misconception.

  Try like this

  Get-Datastore-Name ' * xxx *' |

  Get - VM | Select the name,

  @{N = "Datastore"; E={$_. {{ExtensionData.Config.Files.VmPathName.split ('[]') [1]}} |

  Tri-objet-property data store name |

• Total latancy in data warehouses

  Hello

  My host has some datastores.one of them have high latency. What should I do?

  We know total latency = device katency + kernel latency if suppose us device or kernel is high, how should solve the problem?

  Thank you

  What I often find that alerts latency for data warehouses are related to CONSIDERING moves. Need large pieces of mobile data respond to a project. Are your warehouses of data showing high without cause latency? for long periods of time?

  I have the internal team of vcenter provide guidance on what they consider the latency for ps read and write ps and make these TOUGH KPI threshold in vcops. So when an alert occurs it is a matter of understanding unplanned planned vs, so it's a matter of drilling data with your experts.

  In my humble OPINION - be admin on vcops does not mean that you know the environment better than your teams... This means that you have useful data to share and then develop the best levels together and the SOP for what latency occurs and the steps to follow. We working through such things now... and test the adapter for Symmetrix. Looking is not on the HBA level so miss us some key data points, but we are working on the adapter to txt and other methods to get better data in vcops.

• Script to list all the warehouses of data in a cluster, the virtual machines on the data store and the host of the virtual machine is on

  We have warehouses of data which are seen by more than one cluster. I need a script that will display:

  all stores of data seen by a cluster

  the virtual machines on the data store

  the host of the virtual machine is on

  the cluster the host is in

  The output I want is

  name of the store of data, the VM name, host name, the name of the Cluster

  any help would be appreciated

  Pretty sure this will do what you need:

  $report = @()
  Foreach($cluster in Get-Cluster){
      $datastores = $cluster | Get-VMHost | Get-Datastore
      foreach($datastore in $datastores){
      $vms = $datastore | Get-VM
      If ($vms.count -ge 1){
          foreach($VM in $vms){
          $object = New-Object -TypeName PSObject -Property @{
                Datastore = $datastore.Name
                VM = $VM.Name
                HostName = $VM.VMhost
                Cluster = $cluster
              }
          $report += $object
          }
  
      }
      }
  }
  $report | Export-Csv C:\Temp\VMs.csv -NoTypeInformation -UseCulture
  

  If you only want to shared data warehouses you can then use

  $datastores = $cluster | Get-VMHost | Get-Datastore | Where {$_.Extensiondata.Summary.MultipleHostAccess -eq $True}
  

  Hope this helps

• How to see 5 pools do not VM disks on data warehouses?

  Hello.  I am new to view.  I just started a new job where they have a 5 view with more than 1,000 Linked Clone VM VDI environment.

  There are warehouses of data 3fc which each have about 400 GB of free space by showing in the view tab in vCenter server administrator.  Asked me to create a new pool with 15 virtual machines.  Each VM will require about 35 GB of total disk space (disposable, internal, swap disk and vm).  Therefore, approximately 525 GB of disk space for the virtual machines.

  I know that the amount of disk space required for the virtual machines is too big to fit on one of the data stores.  See split sort virtual machines in three warehouses of data?  If so, how composer decides what data stores to put the virtual disks of each virtual computer on?

  Thanks for your help!

  It has to work this way, you have selected all three data warehouses when you configure the pool.   If this isn't the case, you will need to go back and change the settings of the pool to include data warehouses before starting commissioning.
