• How to select the cluster/resourcepool data store?

  Hello

  as you know others my son, I'm working on a workflow to create several identical virtual machines on a VC-cluster.

  At this time a virtual computer is created like this:

  task = vmFolder.createVM_Task( configSpec, vmCluster.resourcePool);
  

  Context is being filled with the configuration of the virtual machine. vmCluster is a workflow input parameter and contains the cluster.

  It works well, but I still have to specify the data store to store files on a different input parameter, because the cluster has several shared storage units.

  Note also that our clusters have only a single pool of resources, the default.

  Let the user select a data store is not a very nice solution because of possible errors and mistakes (the user can select the local drive of the VMHost, lack of space on the storage selected etc..). But I, as a developer, also can not predefine the storage to use (several storage units, unit of different names etc.).

  Now, what I've been thinking about (and trying to implement) was to get the vmCluster data warehouses or the resourcePool, check if they are put in place for the virtual machine files and if they have enough space for the virtual machine.

  I know how to check the size and which storage are to be used for virtual machines, but I don't know how to get out them of the cluster/resourcepool.

  Can someone help me with this?

  Thank you and

  Concerning

  PS: Is it just me or I really make things complicated with orchestrator here?

  Hi Andreas,

  One way to get the value of storage of data is to use VcSdkConnection.getAllDatastores

  For more information, see here: http://www.vmware.com/support/orchestrator/doc/vco_vsphere41_api/html/VcSdkConnection.html#getAllDatastores

  Personally, I have not played with it, but it seems very powerful.

  There is discussion on the use of xpath in such a case in this topic (to get the value of VMs): http://communities.vmware.com/message/1673575

  Other than that you could:

  -use VcSdkConnection.getAllClusterComputeResource (gets all clusters) or VcSdk.getAllResourcePools

  -in case you work with clusters - each cluster's data store property that returns an array of data for this cluster warehouses

  -in case you use pools of resources, you must check that is the parent of each resource pool and get its data warehouses.

• Clone a virtual machine to a Cluster data store

  Hello

  Really simple (hopefully), but I'm trying to write a workflow that includes the provision of a virtual computer to a cluster of data store. I'm a link to the workflow 'Clone the virtual machine, no customizations' that only accepts a store of input data.

  I hope that I am a bit stupid here and there is a simple answer?

  Thank you.

  There is no simple answer.  DRS clusters are actually a set of rules and not a real thing, you can deploy a VMDK.  I suggest to use Onyx to deploy a virtual computer to a DRS cluster and see what it generates.  If I remember correctly, it executes DRS rules to get a recommendation for where to put a VMDK fundamentally and then uses the exit in order to actually deploy the model.

  I opted to write just a simple workflow that finds the data store with the most of freespace that corresponds to a string - for example, if I have a DRS cluster named DSCluster_ugabuga, I have a lot of data stores named something like "ugabuga... ».  So you ask these storages of data and find the one which most freespace.

• How to find clusters of data store for compute cluster?

  I used PowerCLI script calls within a rest service.  The rest service is spent a bunch of new applications of construction of virtual machine data.  For the deployment, the only data (relevant to this question), I'm getting is the vcenter server and the name of the compute cluster.  I need to find a way to determine which cluster of data store to deploy virtual computer by using the name of the compute cluster.  If I do a get-cluster $clustername | FL * I see no correlation between the computer cluster and the cluster data store.

  If I get info on a VM (get-vmhost $vmhost) host in a cluster, I see the datastoreIDlist as a property of the object VMhost and can see the warehouses of data (not datastoreclusters) facing it.  Which is not ideal, but it might be doable.

  I know there is a relationship between compute clusters and storage that is presented in vcenter.  Why can't I find that in powercli?

• How to remove a data store abandoned?

  Hello! I am the systems administrator for my organization where we have HP P6300 storage attached to our cluster of ESXi5. Usually, if we need a new Vdisk to any virtual computer, we create a new vdisk in storage and add them as a new data store in Vsphere, then we create the file within this new data store vmdk. I had to remove a disk of a virtual server. The steps are as below:

  1 remove the data from the drive

  2. remove the disk from the virtual machine and delete the vmdk file

  3 remove the data from the cluster of data store store

  4. remove the data store

  5 remove the vCenter store data (inventory------Clusters data store and data warehouses-right click on the data store and delete)

  6 - anyone the vdisk to ESXi hosts

  7 remove the vdisk to Storage Manager.

  But I made a mistake and missed the STEP n ° 4 and 5.

  Now I see the attached message whenever I'm trying to remove it. Guidelines for this problem and remove this missing data store in the vCenter?

  Thank you

  Ali

  OK, you have a way of death. The only way to fix it must restart the host.

• What best practices to remove a host server data store without emptying the contents of the data store

  Hi all

  This question was probably asked a million times. the best practice to remove a host server data store without emptying the contents of the data store?

  I have two clusters and I moved host group A to group B. host A is now to see data from Cluster Both A store and Group B datastore. We want that host A to store data in Cluster B. The Cluster a data store is not and can not be empty coz VM A Cluster using data warehouses. So I just unpreset the data LUN to host A store and Reanalyze the data store? Or there is a better way to do it?

  Thank you all

  Yes that's what I meant - should have specified where virtual machines are running.

• Report on the use of data store based on cluster (not data center)

  Hello

  I want to create separate HTML reports for each cluster I have in my virtual Center. I've created a script, but it doesn't seem to work. This script creates outputs separated from HTML based on clusters, but all the files have the same data, i.e. all data that are available in the Vcenter stores. How can I separate them with regard to the cluster in which they are assigned to the place?

• remove the Cluster data store data store

  I have an infrastructure with vCenter and ESXi 4 5.5 I have a data cluster store in SAN with 8 Mon, I need to remove 3 Lun (to be used for other purposes) what is the appropriate procedure

  to remove the Lun (end then to destroy)? Thank you

  Do you want the LUN to use for purpose of non-vSphere? If so, you can just storage vMotion virtual machines since associated LUN data warehouses that you want to decommission (or simply putting the data store in maintenance mode, in this way, that the virtual machines will automatically be migrated). Cleaning after the data store, move the data store from the cluster data store, and then delete the VMware environment data store as described here: best practices: how to properly remove a unit number logic of a host ESX - VMware vSphere Blog - VMware Blogs

• Issue of Cluster data store

  Hello

  Is it possible to have 4 ESXi clusters, each with their own set of SAN data warehouses, all joined to a Cluster of unique data store? I have not found exactly this configuration described anywhere. I understand there are limitations such as 32 data etc. stores and paths to data warehouses will be available from certain hosts.

  Has anyone tried this before? I'm trying to simplify investment VM for Cloud management platform.

  Thank you

  Mike

  This is a supported configuration, and I have a few clients that are running this configuration without problem. Have a look here for details: linking DRS multiple clusters in a single Storage DRS datastore cluster. - frankdenneman.nl

• Question about the creation of cluster data store

  I'm running vSphere 5.1 and want to enable storage Drs before as I have create the cluster data store, I was reading through VMware vSphere 5.1, but don't see any confirmation when I add data to the cluster storage, the virtual machines using these storage of data is not affected.

  Can anyone confirm that the addition of a data to a data cluster store store has no impact on virtual machines running?

  Thank you.

  You can add and remove data warehouses in a cluster of data with VMS running store.

• Disk groups are not visible cluster. vSAN datastore exists. 2 guests (on 8) cluster do not see the vSAN data store. Their storage is not recognized.

  http://i.imgur.com/pqAXtFl.PNG

  http://i.imgur.com/BnztaDD.PNG

  Do not know how even tear it down and rebuild it if the disk groups are not visible. The discs are in good health on each host storage adapters.

  Currently the latest version of vCenter 5.5. Hosts running 5.5 build 2068190

  Just built. Happy to demolish and rebuild. Just do not know why it is not visible on the two hosts and the disk groups are only recognized 3 guests when more are contributing. Also strange that I can't get the disk groups to fill in vCenter. I tried two different browsers (chrome and IE).

  I have now works.

  All the identical 5.5 relies on ESXi hosts. All hosts are homogeneous CPU/sum of the prospects for disk controller / installed RAM/storage.

  I have work. I had to manually destroy all traces of the vSAN on each single to help host node:

  (1) put the hosts in maintenance mode and remove the cluster. I was unable to disable vSAN in the cluster, I made on each node host (manually via the CLI below) then disconnected web client vCenter and return to finally refresh the ability to disable on the cluster.

  esxcli vsan cluster get - to check the status of each host.

  esxcli vsan cluster drop - the vSAN cluster host.

  storage of vsan esxcli list - view records in the individual host group

  esxcli vsan storage remove-d naa.id_of_magnetic_disks_here - to remove each of the disks in the disk group (you can ignore this using the following command to remove the SSD only falling each disc in this host group).

  esxcli vsan storage remove s naa.id_of_solid_state_disks_here - this is the SSD and all the magnetic disks in a given disk group.

  After that, I was able to manually add hosts to the cluster, leave maintenance mode and configure the disk groups. Aggregated data of the vSAN data store is correct now, and everything is functional.

  Another question for those of you who still read... How to configure such as the VM storage strategy that migrates towards (or inspired) the vSAN data store will immediately resume the default storage policy, I built for VSANs?

  Thanks for anyone who has followed.

• A cluster of vCenter will share a single data store on a NAS?

  I have a vCenter 3 ESX host cluster. I want that these 3 hosts to share a single data store on a NAS (Dell Powervault md36xxi).

  
  

  The goal is that if one of the hosts go down, the other two still have access to the unique shared data store on the NAS.

  So far, I've been able to create a separate data store for each host on my NAS.

  Any help would be greatly appreciated. Thanks in advance.

  Since we normally have a 1:1 mapping between LUNS and data store, if the three hosts share the same LUN, then they will also share the data store even... just the map the LUN to all three hosts, using the vCenter create a store of data with vmfs format and three guests will share the data store. If after having create the data store on the hosts of the first, if other hosts do not see yet the store data, just try to rescan the host for new storage devices and data warehouses.

• Bay of Cluster data store turns into a string?

  I am very new to the vCO (or maybe I should call vRO now) and therefor also very new to script and digging through the API, so I apologize if this is a bit of a noob question.

  I'm currently running below script to find the data store cluster to a cluster host with more available space.

  However, I also want to check for the text in the name of the data store. For this I use indexOf.

  If indexOf detects all matches, it should add the DSC (or pod) in a table.

  But it seems that this operation turns my array into a string.

  Because it is a new environment I have only a DSC connected to the cluster hosts, but I still think that it should be able to be an array with a single value?

  Find the Cluster and related variables

  var hostarray = System.getModule ("com.vmware.library.vc.cluster") .getAllHostSystemsOfCluster (inCluster);

  Host = hostarray [0];

  pool = inCluster. ResourcePool;

  level of var = 'High';

  Find warehouses of data in Cluster

  var = host.datastore data warehouses;

  Find Clusters of Cluster data store

  var storagePods = new Array();

  var storagePodNames = new Array();

  for (d in data warehouses) {

  if (data [d].parent.vimType warehouses is "StoragePod") {

  if (storagePodNames.indexOf (datastores [d].parent.name) < = - 1). {

  storagePodNames.push (datastores [d].parent.name);

  storagePods.push (datastores [d] .parent);

  }

  }

  }

  System.log (' storagePods: ' + storagePods [0].) Summary.freeSpace);

  Find Clusters corresponding to the layer data store

  var podTierArray = new Array();

  for each {(var pod in storagePods)

       if (pod.name.indexOf (tier) > = 0) {

  podTierArray += pod;

  }

  }

  podTierArray becomes a string instead of table after above operation :(((

  System.log (' podTierArray: ' + podTierArray [0]);

  System .log (' podTierArray: ' + podTierArray);

  Here is the result of the above script:

  [12:24:27.307 2015-02-27] [I] storagePods: 4497773428736

  [12:24:27.308 2015-02-27] [I] podTierArray: D

  [12:24:27.310 2015-02-27] [I] podTierArray: DynamicWrapper (Instance): [VcDatastore]-[class com.vmware.vmo.plugin.vi4.model.VimDatastore] - VALUE: < datastore-386 > Datastore 'high Datastore01 '.

  
  

  I'm guessing that "D" is the first character in the string (which should be an array), which is also attested by the third row of the output when I print the entire string.

  Because this time is a string I can't use it as an object, for example "podTierArray. Summary.freeSpace' give me an error that it is a property not set.
  

  In addition, as you can see earlier when I use the variable ""storagePods "this is a picture I have run the podTierArray. "

  
  

  Why would he suddenly become a string instead of an array of objects?
  

  Hi Oskar,

  It happens because of this line in your code

  podTierArray += pod;
  

  This is not the right way to add the element in a table. You need to take it

  podTierArray.push(pod);
