• vCO - get all clusters in a data center

  Do you know how can I get a list of all the Clusters that are in a center of some data?

  Thanks in advance

  This task code that contains a script can do...

  Entry: Data Center (VC:Datacenter)

  Output: clusters (table / VC:ClusterComputeResource)

  Script:

  var clusters = new Array;
  var folder = datacenter.hostFolder;
  var children = folder.childEntity;
  for each (child in children){
      if (child instanceof VcClusterComputeResource){
          clusters.push(child);
          System.debug("Cluster added: "+child.name);
      }
  }
  

  If the above code to be used in an action rather than a script task, simply add the following to the first line (useful when used in presentation settings):

  if(datacenter == null) return null;
  

  And this for the last line:

  return clusters;
  

• Create a VMFS and add it to all hosts in a cluster

  Hi, I'm trying to create a script in order to create a data store and then present it to all hosts in a cluster.

  any idea?

  Add-PSSnapin "Vmware.VimAutomation.Core".
  # - Create Variables -
  #$vcenter = %1
  ##---Connexion to the VirtualCenter-
  $Server = $args [0]
  $ClusterName = $args [1]
  $VMHost = {get-Cluster $ClusterName |} Get-VMHost}
  $Name = $args [2]
  $Path = $args [3]
  SE connect-VIserver $Server

  Get-VMHost $VMHost | New-store data-Server $Server - name $Name - path $Path - Vmfs-confirm: $false
  Get-VMHostStorage - $VMHost - RescanAllHba - RescanVmfs-r VMHost

  You must be connected to the Cluster Get

  You need not create the data store on all nodes of the cluster.

  Just 1 host is sufficient.

  And the creation of a new store of data forces a new analysis.

  So that should be enough

  Add-PSSnapin "Vmware.VimAutomation.Core" ## ----Créer les  Variables----#$vcenter = %1## ----Connexion au VirtualCenter---- 
  
  $Server = $Args[0]$ClusterName = $Args[1]
  

  Connect-VIserver $Server
  

  
  $VMHost = Get-Cluster $ClusterName | Get-VMHost | Select -First 1 
  
  $Name = $Args[2] $Path = $Args[3]  Get-VMHost $VMHost | New-Datastore -Server $Server -Name $Name -Path $Path -Vmfs -Confirm:$false
  

• Collection for the PowerCLI scripting requirements

  Someone at - it a good model that helps you organize information, gathering process when you go to the management or to a customer to get for scripts and automation requirements that they want to do?  Y at - it a Web page or a book that puts this kind of thing in a structured methodology or at least one practical how to guide?

  For example, what kinds of questions should I go to make sure that I understand any of my script is supposed to do and help the management or the customer understand what THEY want to do, and get a consensus agreement on the functional requirements for my powerCLI script?

  Your suggestions of entry, welcome masters strategies.

  This question is not really unique for PowerCLI scripting, but all scripts/programs, to write (for yourself or for a customer |).

  And of course, there are always the classic answer "it depends".

  If it is a small task that you write yourself, the requirements are pretty obvious.

  Most of the time, you have the requirements in your head, but it does not have to write in schematic form.

  When you write for a customer, by definition be more formal (I guess).

  An article I like, is the Introduction to gather our creative use cases and requirements published in the Code review.

• Trying to create a script that lists all clusters in a data center

  Hello

  I am trying to create a script that exports a vCenter configuration essentially and imports it in a new vCenter. I want the script to run without specifying a center of data manually. All the scripts I've seen you need to manually enter the data center.

  So, how to do a list of all the data centers with clusters in each of them? I also want to create a variable that contains the groups for the respective data centers. Here's a basic idea of what I want to do:

  $Datacenters = get-data center

  foreach ($Datacenter to $Datacenters)

  {

  $cluster = get-Cluster-location $Datacenter

  Write-Host "list of clusters in $Datacenters.

  Write-Host "$Cluster".

  }

  Who will give me the output like this:

  List cluster Datacenter1

  cluster2 CLUSTER1

  List cluster Datacenter2

  cluster3 cluster4

  But I don't know how I can get so I have variable like this:

  $datacenter1 = cluster1, cluster2

  $datacenter2 = cluster3, cluster4

  Did you mean something like this?

  Get-data center | %{

  New-Variable - Name $_. Name - value ([string]: join ("," (Get-Cluster-location $_ | % {$_.}))) Name})))

  }

• Script to pull the last timestamp spend all hosts in a cluster?

  Hi all

  Lately I have seen an issue where my host 5.1 logging abruptly stops and the other remote access to every host I have no way of knowing what happened.

  Is it possible to account for the last, for example hostd.log timestamp for each host in a cluster?

  Thank you

  Tony

  Try something like this

  foreach($esx in Get-Cluster -Name MyCluster | Get-VMHost){  $log = Get-Log -Key hostd -VMHost $esx  $esx | Select Name,@{N="Last entry";E={[datetime]($log.entries[-1].Split(' ')[0])}}}
  

  But be aware that fetch a newspaper of the ESXi could take some time.

  The script needs get the full log, to be able to extract the last line

• License question - do need me a VSAN license for all hosts in a cluster?

  I have a 6 host cluster exist using the VSphere Essentials Plus package with a single server VCenter. Can I buy x VSAN 3 licenses, for example to add the storage to the 3 hosts I have install the VSAN license on and access the VSAN of the 3 other hosts in the cluster data store? (Assuming only 1 CPU for each host.)

  Thank you!

  Hi Daniel,.

  Since Virtual SAN is activated at the level of a cluster, all cluster hosts can consume storage since the virtual SAN data store regardless of how many guests contribute to storage. So to answer your question, you need all 6 hosts in your cluster license, even though only 3 of them contributed storage.

  Also note that the licenses are per CPU so in your scenario if each host has 2 CPUs, you need a total of 12 CPU licenses. I hope this helps.

• Orchestrator 5.1 REPORT-all the virtual machines in the data center and create a CSV file

  Hello

  What I basically want to do is create a report CSV of all virtual machines in the data center with various information (VMname, domain name FULL, IPaddress, status, data warehouses, tools etc...).  The export list in the client feature is insufficient (especially for any KPI report).

  Problem: (workflow is still under construction so real email send does not not and need to clean the code)

  I am stuck at the part of the creation of a table that can be parsed correctly in the CSV file.  2 ways I've tried will produce a report of single object or combine all of the table into a single string (where I am now).  I think the main problem I have is that I have to create a 2D within my service to push toward the final table that is written to the CSV format.  Basically, I do not understand how to push my variables in a loop of a table.

  Any help or assistance?

  Thank you

  B

  BOOM!

  Added some comments, removed the hardcoded in the csv temp file, deleted path the hardcoded port 25 for SMTP - mail settings should come from the configuration of the MAIL plug-in. And fixed / confirmed that the workflow now includes the attachment for e-mail and ends with success!

• Good way to stop all hosts in a cluster

  I have a small environment with 2 esxi hosts in a cluster. my company will have 2 planned outages that I need to close all the servers down including the esxi hosts. What is the right way to do this to make sure that everything is properly turned off and no vmotion will trigger that everything will be turned off?

  Thank you!

  Welcome to the community - the order you need to shute down is:

  1. Stop the virtual machines
  2. Put the hosts in MAintenance mode
  3. Stop hosts
  4. Stop vcenter (if vCenter is a virtual machine, you will need to connect to each host separately and close).

  To put it all together

  1. Start the hosts
  2. Begin to vCenter

• List of all hosts in a Cluster, the Local single data warehouses

  I had a few attempts but failed miserably.

  Can LucD - you help maybe?

  I just need to list each local VMFS Datastore and ideally have each size. The idea is to get this info in a separate calculation in a hash table, something like this:

  @{N = "Datastore"; {E = {* list all the Local DS for the host that is currently being questioned and their respective sizes in here *}}

  I hope I explained well enough...

  Thank you very much!

• PowerCLI script for DatastoreCluster, data warehouses and the size info, DataCenter, Clusters

  Hello - I am looking to remove the DatastoreClusters and then list data warehouses as well with their size (total size, used space, free space, put in service, uncommitted space) and the total number of virtual machines on this data store. I would also like to understand what data center and they are on clusters. Is this possible? I might want to limit what is displayed in data warehouses that are 13 percent of free space or less.

  Thank you

  Of course, try this way

  Get-Datastore.

• PowerCLI script to check the setting of syslog on a whole cluster?

  Hey guys,.

  I'm looking for a way to check the setting configured for syslog remote on a large cluster of ESXi. Is it possible to easily check by cluster?

  Thanks in advance,

  The following PowerCLI script will give you the servers remote syslog for all hosts in a cluster:

  Get-Cluster "MyCluster" | Get-VMHost | ForEach-Object {
    $VMhost = $_
    $VMHost | Get-VMHostSysLogServer | ForEach-Object {
      $Report = "" | Select-Object -Property VMHost,SyslogServer,Port

      $Report.SyslogServer = $_.Host
      $Report.Port = $_.Port
      $Report
    }
  }
