• ESXi 5.1 and VMFS-3 data warehouses

  We have an existing environment to ESX 3.5 Update 5 7 host and an EMC CX3-10 x iSCSI SAN. We go to decomission 2 ESX hosts and replace them with hardware ESXi 5.1 and recent guests. We realize that we no longer able to manage these hosts ESXi from our Virtual Center 2.5 console, but these two hosts will run a minimum number of virtual machines (Exchange 2010 multirole) that don't use VMotion, DRS and HA.

  Our understanding is that ESX5.1 can see and use VMFS-3 data warehouses. Is it true that, once we plugged the new 5.1 ESXi hosts to our SAN and you can see all the existing LUN that we should be able to stop the virtual machines on two ESX 3.5 hosts and start the virtual machines on the host ESX 5.1 computers?

  Everyone has problems running ESXi 5.1 with VMFS-3 data warehouses?

  Some data warehouses VMFS-3 existing could be improved to VMFS-5 because they are only used by the virtual machines that work on 5.1 ESXi hosts. But some of the data warehouses VMFS-3 existing is not extensible because they are used by the virtual machines running on ESX 3.5 other hosts. In other words, a single virtual machine can have virtual drives running on the VMFS-3 and VMFS-5 warehouses of data at the same time?

  Thank you

  VMFS version isn't a problem. What I am more concerned by the fact that your storage system is not supported by ESXi 5.1.

• After the migration of ESXi 4.1 to 5.0 Update 1, ESXi containing the missing data store

  I intend to upgrade to an ESXi 4.1 production host, but I want to run through an upgrade of test on a separate machine. I created this using a virtual machine and the upgrade went well. However, now when I insert my vSphere client, I don't see the data store that contains data to my VM.

  Before migrating to 5, I had 2 drives, a disk of 4 GB for ESXi, and a 40 GB drive for the data of the VM installation. I could see and access times stores via the 4.1 vSphere client, but once the upgrade only the VM data store is available. Is there a reason that this is the case?

  I've updated but has not changed the partitions of data store. I have selected to migrate and keep the VMFS store, which was VMFS-3. I also tried to add the store drive 4 GB with the customer data, but an error message: "the selected disk already has a vmfs data store or the host cannot perform a conversion of partition table.
  Select another disk.

  I found this article on error message: http://KB.VMware.com/kb/2000454 , but I never actually removed from the data store. With the help of the 5.0 ESXi update I can see the VMFS store on 4 GB drive, which should have about 3.2 GB of available disk space (the rest being used by the hypervisor).

  Recommended someone else try esxconfig-volume - the list, and then use the output to a mount (http://communities.vmware.com/message/1666168#1666168), but the list command had no output at all.

  I searched through the forums and Google but you saw nothing.

  ESXi 5 has a different architecture, and I think that the problem is the size of the disk (too small) and the partition of scratch required.

  Have a look here:

• ESXi host sees no data store after the reboot

  Hi all

  I'm new to the community and ESXi itself.  Everything has been working great until today when I rebooted my host.

  I installed it on a Dell T110 server, we had in the back for testing.  It has a 250 GB HARD drive installed in the case.  ESXi installed fine and I had 220 GB or more storage at my disposal.  Multiple VM installed, and once again, everything seems to work properly.

  Today, I wanted to activate usb passthrough for a Server 2008 VM I installed it, I went through the process and had to reboot the host at the end.

  After the restart, he seems to have forgotten the HARD disk that is installed and is no longer, I see my store data or virtual machine access I had running.

  There are a couple screenshots attachedthat screen what I see.

  Thanks for any help or advice!

  Is this the same controller that is attached to the 250 GB HARD drive? Passing the controller to the virtual computer may have unpresented it host, then you won't be able to access and to store configuration settings. Since this is a test system you can consider / try to run "Reset System Configuration" from the DCUI. If this does not work, you may need to reinstall ESXi of CD (the VMFS retaining of course data store).

• Try to re-signing and mount a data store

  Hi all

  I'm stuck trying to develop a "workflow" and hoping you can help. We need to make a daily DR copy of a production database and edit this copy on another virtual machine. The database feeds a hard with his own logic unit number and is heavily used, so we can suspend only wrote a few minutes.

  
  

  Here are the high-level workflow:

  1. Suspend the entries in the database
  2. Create a virtual copy (snapshot) of the LUN on our 3PAR
  3. Resume database entries
  4. Export (present) the virtual copy of the 3PAR to the ESXi cluster
  5. A rescan storage on all hosts in the cluster
  6. Add the LUN and re-signature of the data store
  7. Mount the VMDK from the new LUN to the VM test

  I fight a bit to make the portion of ESXi work. I can re-scan storage successfully on my host, but I'm not able to go up and re-signing of the data store newly discovered. Onyx told me to use resignatureUnresolvedVmfsVolume_Task , but the action failed with "TypeError: cannot find the resignatureUnresolvedVmfsVolume_Task function in the object (Instance) DynamicWrapper: [VcHostSystem]-[class com.vmware.vmo.plugin.vi4.model.VimHostSystem]" I run 5.5.2 vRO/vCO and don't have the library installed vi4 nor do I have all the actions that will be re-signing a volume.

  So I wonder, ResignatureUnresolvedVmfsVolume_Task has been deprecated and replaced by something else? Or did someone knows a library/plugin that I can add to vRO who will give me the opportunity to re-signing a data store?

  Thanks in advance for any help.

  See you soon!

  Hello

  The error message, it seems you are trying to call the method resignatureUnresolvedVmfsVolume_Task() on the object of type VcHostSystem. something like that

  var task = hostSystem.resignatureUnresolvedVmfsVolume_Task(spec);
  

  The problem is that resignatureUnresolvedVmfsVolume_Task() is not a method of type VcHostSystem, but in VcHostDatastoreSystemcharacters, therefore, you get this error.

  To fix it, you must obtain an object of type VcHostDatastoreSystem. Research in the API Explorer, you should be able to get VcHostDatastoreSystem object VcHostSystem object through the configManager property (which returns an object of type VcHostConfigManager), then property of datastoreSystem . Something like the following code:

  var task = hostSystem.configManager.datastoreSystem.resignatureUnresolvedVmfsVolume_Task(spec);
  

  I don't have a good environment to test, but it should work.

  I hope this helps.

• Host virtual computer and Migration of data store

  I'm curious. I have an environment with Cisco UCS UC servers without them. Due to they are C-Series all storage is local for UC virtual machines run. I'll add some of the UCS C-Series servers and you want to move two of my current C-Series server CPU virtual machines to the new. I have the license Enterprise Plus 4.1 for all servers and execution of vCenter. The migration will be basicall move local data store to store local data as well under the name from host to host. My plan is to turn off the virtual machines and migrate both host and the data store at the same time. I have groups of ports built as follows:

  Port of VMKernerl groups:

  -Storage (for future shared storage)

  -vMotion

  -PI

  -ESXi Mgmt

  Virtual machine:

  -CPU VMS

  -Machines virtual server

  My overall question is during this migration takes place this network (or a group of Port) will be the traffic go anywhere for the move? My guess is because it is the local storage, it will use the Mgmt. ESXi

  Thank you!

  If the virtual machine will be moved to store Local data to store common data shared through 2 esxi host, then the storage shared for local storage.

  So this will be the case through network vMotion and not via the management network.

  But you can enable vmotion on management network itself. If you have configured like this then yes communication will be via the management via vmotion network IPkerenel active network.

• ISO on a vm images data store?

  Hey guys how do I.

  Download my iso image I have on a USB stick in the pictures of vm data store folder.

  while I can load my BONE in him.

  There is no limit to this title, use the # df h command to monitor the size of root file system and ensure that the % used is not more than 90%. Its a best cuz practice if we have no space available for him spend crazy acts of root file system and the server could be disconnected from VC or network configuration would be lost

• InvalidProperty when you info.vmfs the data store when you query properties

  When I try to interview with a specification of property to store data as below, it throws an exception.

  PropertySpec pdsspec = DataObjectFactory.newInstance (PropertySpec.class);

  TypeName DatastoreType = TypeName.forClass (Datastore.class);

  pdsspec.setType (DatastoreType);

  pdsspec.setAll (Boolean.FALSE);

  pdsspec.setPathSet (new String() {"host", "info.name", "summary.url", "summary.capacity", "summary.freeSpace", "info.vmfs.type"});

  I discovered that info.vmfs.type is originally the InvalidProperty exception. any idea? No work around?

  Thank you

  Vincent

  Hello

  Yes you are right, you must first get the instance of 'info' and then get properties.

  Another approach for the property 'type' store data during extraction is to use 'summary.type' in the setPathSet. This extract the type of the data store.

  I hope this helps.

• Cancellation of the assignment and reassign the data store by using different LUNS that datastore has not appeared.

  Hi all

  I have a data store after vdisk1 I have not assigned the vdisk to data store and reread the esxserver, the data store has disappeared.

  Again, I assigned the vdisk using the same number of logical unit as before and reread the esxserver, datastore appeared again return.

  But if I use a different assignment vdisk lun and on a new analysis of data store does not appear.

  Can someone tell me if the LUN must be even to see the store of data back again.

  If so why. ?

  Is there a vmware documentation to substantiate this claim.

  concerning

  Neela

  What do you mean by vdisk1?  The data store are stored as metadata on the LUN, when is formatted VMFS.  If you remove the LUN the VMFS is sitting on, then Yes, the data store will disappear.  If you only remove the vmdk who lives on this data store, then no, the data store must remain as it is, and you should be able to move the vmdk on the data store as needed.

• How to understand that ESXi has mounted a data store?

  Dear members,

  I am a new Bee with VMware.  When I click in the cluster of ESXi, I see nodes that are part of the cluster, but also see mounted on it data warehouses.

  How do I know which node is pwning the data store (or what node has a particular data store mounted?)?

  Thank you

  Rahul

  Actually, there is no owner. All data in ESXi stores are accessible by multiple hosts at the same time.

• Rename the VM and labels in data store locations

  I remember my days with vSphere 4 x that I had to rename a virtual computer once.   But, the vmdk/vmx partner, files etc. and even the record in the data store has not changed.   However, when I did a Migration of vStorage in another store of data with the virtual machine also migrate to a new host when it was finished... all sync'd up.   or that's how I remember it.

  But, I'm now told my my virtual colleague that rename a virtual machine and to migrate to vStorage and VM migration to a new host WILL NOT synchronize the naming and lables.  is that correct?  I am almost sure that it worked in vSphere 4.

  It was behavior that was introduced in vSphere 5. It has since been resolved in Vcenter Server 5.0 Update 2 and 5.1 Update1. See the article I've linked below:

  VMware KB: vSphere 5.x Storage vMotion is not renaming the files of virtual machines at the end of migration

• ESXi 4.0 RAID5 data store configuration.

  I was wondering what the recommended way to configure an array RAID5 with about 5 TB available DAS, for a host ESXi 4 which will take a couple Windows 2003 VMs, a couple Windows XP machines virtual and some Linux virtual machines. enter several smaller virtual disks for each virtual machine or a couple more large virtual disks for virtual machines to share the table would be the best approach?

  Not really, because they all have the same underlying om pin set.  It's quite a dangerous configuration if extensions are on different disks games, as the failure of one will wipe the lot!

  Please give points for any helpful answer.

• Get-view datastore and get-function data store

  Hey, my first time posting here.

  Creating a function which takes as input pipeline and processes that each entry through process in a function. I want the function to be able to take the 'get - view - viewtype datastore' and 'get-datastore' as input.

  Obtained in what concerns obtaining the opinion of the GET and get-datastore work separately in the service, but when I want the function to be able to take one or the other input that I can't make it work.

  Here is the function at this moment, not really work for one of the entries.

  Function Get-DatastoreSpace () {}
  [cmdletbinding()]
  (param
  [Parameter (mandatory = $true,)]
  ValueFromPipeline = $true)]
  $Datastore
  )

  BEGIN {$ReportDatastore = @ ()}

  $row. Datastore_Freespace_GB = [math]: tour ($_.) FreeSpace / 1 gb, 3)

  END {$ReportDatastore}

  Any ideas on how to do this?

  Thanks in advance

  Check the type of the object in the variable $datastore.

  Something like that

  if($datastore -is [VMware.VimAutomation.ViCore.Impl.V1.DatastoreManagement.VmfsDatastoreImpl]){
  # From Get-Datastore
  }
  elseif($datastore -is [VMware.Vim.Datastore]){
  # From Get-View -ViewType Datastore

  # Wrong object type

• install esxi 4.1 and the data store on the same server

  Hello

  I want to install esxi 4.1 and the data store on the same server.

  My problem is that I can't make partitions to really separate them and I would reinstall esxi without wiping the data store.

  Y at - it another way to put a record out of the raid only to install esxi.

  I also do not install on a USB key.

  Thank you

  Thank you

  AZEL,

  Can you give us more details about your current environment?  What is the size and the data store space used? Do you have any storage of additional network attached to the host (for backup purposes)?

  My assumptions of your post do you have 1 stand-alone host with ESXi 4.1 aready installed and you also have a local data store on the same host, but you want to re - install ESXi 4.1 while keeping the contents fo the data store.  Is this correct?
