Add VMS to DRS rule

Similar Questions

• DRS rules

  We have a cluster with 5 guests esxi 4.1. Our web team has a collection of 10 virtual machines they would like to have at most 2 of their virtual machines running on the same host at any given time. Is this possible using the DRS rules?

  I've set up two groups of hosts and virtual machines, a group of virtual machines 1-5 and another 6-10 guests then 1-2 and 3-4 (leaving a 5 hosts on groups, but I guess I could just add it to the second group to keep them together...) I then set up for VM 1-5 could only run 1-2 hosts and VMs 6-10 may only work on 3-4. This does not have the requirement to have only 2 virtual machines on a host at a time.

  Any suggestions?

  Thank you

  Assuming you entered controll activated with a threshold of 20% then none.

  As the DRS rules are 'should' rather than 'having '.  Which means that if the host ESXi01 fails, then WEB01 and WEB02 will work on any other host, when this host is repaired or get back online, DRS will migrate them back to her.

• Guests report in DRS-rules

  Hello

  We are currently using DRS for the distribution of Windows VMs on specific hosts in our groups. These hosts are grouped into a "Windows Hosts licensed" DRS group in each cluster.

  For our license management, I need to declare the current number of hosts (and host) attributed to these groups of DRS each month.

  As the environment is more and more bigger I want to automate this task by using a regular report.

  How can I get a list of relevant hosts including physical processors per cluster and a total number of CPU?

  We use vSphere 5.1 and PowerCLI does not seem to offer much for DRS-groups out of the box.

  I just need to know how to get the list hosts, I can do anything around this (adding PSModule, connection to vVenter, report by mail, etc.) by myself

  Any help appreciated.

  Hi Daniel,.

  right, PowerCLI does not offer a large part of the box.

  But there is a module, you can import:

• Affinity DRS rules?

  Hello! I use Affinity DRS rules at present with DRS groups etc. My question is if it is possible for a little more advanced with the DRS group management? Is it possible to group together (for example tag)-based VM rather than manually? So ideally, I could go to a stage where I can score a large number of virtual machines in a certain way (tag/etc. naming convention) and make them part of a group of DRS.

  The goal is to link a large number of virtual machines to hosts for licensing reasons, so I don't know that this has been done before. Obviously a separate group would work but not the most effective use of resources. I am looking for a type of soft partitioning almost (with software!)

  Any ideas or suggestions would be greatly appreciated as always!

  Thanks and greetings

  A way to do would be to put the virtual machines selected on specific storage and storage only serve to a specific host within the cluster - in this way you would not need to affinity of all rules, and the VMs system would remain "limited" for guests who 'see' storage...

• DRS Rule for Host affinity check names of datatore that they match to the hosts

  DRSRules - list of host affinity rules

  Host affinity rules

  Cluster	Activated	Name	Solidarity	VM	Host of the rule	Running

  This module of vCheck will show me if one of my virtual machines are not running according to the rules, but I want to look deeper.

  DRS Rule for Host affinity check names of datatore that they match to the hosts

  Our guests all start with three characters make the difference between SiteA1 and SiteB1, that is sa1host1 sa1host2... sa1host9 and sb2host1, sb2host2, sb2host9, etc.

  Our warehouses are the names "sa1_exch01", "sa1_sql_01", sa1_data_01"for all data stores that are found on the Site1.  While the warehouses of data named 'sb2_exch01', 'sb2_sql_01', sb2_data_01' for all data stores that are found on the Site2.

  Can help you with a script that will check all virtual machines on the hosts on Site1 and report those who have warehouses of data does begin with 'sa1' and similarly all virtual machines on the hosts on the Site2 but give report of those who have warehouses of data that do not begin with "sb2.

  Try something like this

  $vms = Get-View -ViewType VirtualMachine -Property Name,Datastore,"Runtime.Host"
  
  foreach($vm in $vms){    $esx = Get-View $vm.Runtime.Host -Property Name    $ds = Get-View $vm.Datastore -Property Name    if($ds | where {$_.Name.Substring(0,3) -notmatch $esx.Name.Substring(0,3)}){        $vm | Select Name,            @{N="Site";E={if($esx.Name.Substring(0,3) -eq "sa1"){"SiteA1"}else{"SiteB1"}}},            @{N="Host";E={$esx.Name.Split('.')[0]}},            @{N="DS";E={[string]::Join(',',($ds | %{$_.Name}))}}    }}
  

  It should list all the virtual machines that do not follow the rule.

• How to get a list of the DRS rules and their virtual machines.

  If I try the following, I get no output. (PowerShell 2, vCenter & ESXi 5.1, PowerCLI 5.1 Release 1)

  
  ()get-cluster ). ExtensionData.ConfigurationEx.group |? {$_.vm}

  or

  ()get-cluster ). ExtensionData.ConfigurationEx.group

  I know that I have a DRS rule because when I try the following I am able to see it in Object Explorer in PowerGUI and I created it just in the Web Client.

  $Clusters = Get-Cluster

  The problem is that you have DRS groups who do not have vms - possibly accommodate groups of DRS.  If you want only vms something like this should work and does not give the error:

  foreach ($cluster (get-cluster)) {}

  write-host "$($cluster.name)".

  foreach ($drsGroup in $cluster. ExtensionData.ConfigurationEx.group) {}

  write-host "$($drsGroup.name)".

  {foreach ($vm to $drsGroup.vm)}

  If {($vm)

  $vmname = (get-vm-id $vm) .name

  write-host "$vmname".

  }

  }

  }

  ECHO «»

  }

  If you want to get the VMhosts and the VirtualMachines then try this:

  foreach ($cluster (get-cluster)) {}

  write-host "$($cluster.name)".

  foreach ($drsGroup in $cluster. ExtensionData.ConfigurationEx.group) {}

  write-host "$($drsGroup.name)".

  write-host "VMHosts".

  {foreach ($vmhost to $drsGroup.host)}

  If {($vmhost)

  $esx = (get-vmhost-id $vmhost) .name

  write-host "$esx".

  }

  }

  ECHO «»

  write-host "Virtual Machines".

  {foreach ($vm to $drsGroup.vm)}

  If {($vm)

  $vmname = (get-vm-id $vm) .name

  write-host "$vmname".

  }

  }

• DRS Rule - separate virtual machines

  I have a DRS rule to separate the 2 virtual machines, but when I vmotion two virtual machines on the same host, it allows him to do. Why is this?

  I need to separate VMs on separate hosts at all times

  OK, I had the level of automation to manual, so he won't move the virtual machine. Once I changed it to automatic, its moved the VM on the host.

• DRS rules and Resource Pools

  Is it possible to assign the DRS rules to Resource Pools instead of creating groups of DRS and adding to the DRS group VMs and then creating a rule
  I ask this question because of a problem that I currently have
  I am far from being an expert as you'll see soon and back to the use of support groups
  If it I'll give you my scenario
  I have 4 ESX host in my test group
  2 hosts are connected to zFCP
  And all 4 are connected to independent contractors
  I have a resorce pool call FC and another called ISCSI
  We constantly evolve around VM between these 2 pools
  The highest availability VM remains on the rest on ISCSI FC
  I would like to create a rule that States if a virtual machine is in the RP FC then he must reside on host A and B, and if it resides on ISCSI it can reside on any host
  I realize that there is still other issues involved here as data themselves warehouses
  but it is another matter that he owns the rights
  We migrate VMs and the data store when we leave the virtual machine to another RP 1
  If the rule would be always true
  I would like to hear from you
  on this topic
  for now I just use rules and groups of DRS
  Thank you

  I don't think this is possible from the point of view of rule affinity DRS, as he has no relationship with resources or VM disk pools. This seems to be a single-use resource pools.

  You could probably do with a set of scripts PowerCLI who would check two resource pools and ensure that the virtual machines to the breast have their records on the correct data store and if not do a svMotion.

• Antiafinidad en DRS rules

• List the contents of a cluster VM group in a DRS Rule

  Hello

  I'm looking for a script that lists the contents of a cluster VM Group in a rule of DRS.

  Example: we have a single cluster vmware 'CL-TEST' DRS 2 'GP1 and GP2' groups that contain several virtual machines.

  We want to export the content of each group of DRS in an excel file.

  Any idea?

  Thank you

• Looking for a way to create an automated and large number of DRS rules.

  For example, I have a lot of machines named like this;

  Fs001a

  Fs001b

  I need to create AntiAffinity rules to keep the 'a' and 'b' machines on separate hosts.

  The created rule should be like "Fs001" and both machines.

  New-DrsRule-development of Cluster-name Fs001 - KeepTogether $false VM - Fs001a, Fs001b

  Any help/direction with powercli script that can do this would be greatly appreciated. I don't know how to handle the name match in powershell. It's something I want to run as a scheduled task to avoid human error in the rules missed or incorrect.

  Try like this

  Get-VM -Name *[ab] |Group-Object -Property {$_ -match "(?.*)[a|b]"; $Matches["name"]} | where {$_.Count -eq 2} | %{    New-DrsRule -Cluster Development -Name $_.Values[0][1] -KeepTogether $false -VM $_.Group}
  

  Only when the script detects 2 identical names (one ends with one and the other with b), he creates a rule of DRS

• List of VMS in DRS group

  In vSphere, you can right-click on a Cluster, click on "change settings > DRS Group Manager > (select a group), change" and view the list of virtual machines that are in the cluster.

  I'm looking to get this list even with the SDK... I was hunting for a way to do it but cannot find where in the API it is perhaps, the ideas of how I could get the list?

  Happy to provide the code so far, but it's just a simple cluster-related statistics and information; anything related to the issue.

  It is nestled in ClusterConfigInfoEx data.

  So you get your clusters and then look at what follows-

  $cluster-> {configurationEx}-> {Group}

  There are two types of groups, host and the Vm.  You can then check the type of groups of MV and the list of members.  You may also look at $cluster-> {configurationEx}-> {rule} if you want to see if its a rule group refines or disaffine.

• VM to host in DRS rules

  If you use the new 'vm to host' rules 4.1, you can for example select the VM in Vm-Group-1 MUST be running on host-group-2. Here "should" is sweeter than "needs", as in it will work on other hosts, but my question is when this is allowed?

  In case of failure, or is it in the case of resources approve? In other words, if, for example, hosts in Host-groups-2 run 100% cpu all of them, DRS will pass a VM "should" to another host?

  It is in the case of resources approve because HA is not aware of the preferential rules. VMware vSphere 4.1 HA and DRS technical deepdive, page 137.
