• 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

• Name of list and MPIO policy data store

  How to add the name of data instead of the CanonicalName store using the used below command:

• 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.

• ESXi and VMFS imaging data store

  I need to mass produce ESXi USB key as well as a large store of data VMFS.  We know good products or procedures to go on a USB stick of imagery, as well as imaging ESXi a VMFS datastore.

  For the stick, I'd use dd on Linux machine.

  For the data store, you can use a disk imaging tool like Capitol or Ghost or you export your VMS and import destination.

  Once the image is created (or virtual machines are exported) you can easily copy them.

• 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 mount a data store

  Hi all

  I'm new to the forum, so I apologize if I chose the wrong forum in the community for posting this issue.

  We have an ESXi Server 4.0 running on a cluster of 6 guests, vmserver1-6 which I have access through the vSphere client.

  We have recently added more capacity disk on servers, add 5 * 1.95 tb hard disks to the cluster. New hard disks are named SysVMFS10 - 14. The strange thing, I am trying to sort is why these new drives are visible to some of the servers.

  vmserver 1,2,3 and 6 can see all storage of new data, while 4 and 5 vmserver can't see than the last one, SysVMFS14. I thought maybe they must be mounted manually, but I don't know how to do.

  Can anyone shed some light on this for me?

  Kind regards

  By

  First force a rescan storage card, and then check if all hosts in your storage card see same lun.

• 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 = @ ()}
  
  {IN PROCESS
  
  $row = "" | Select-Object Datastore_name, Datastore_Freespace_GB, Datastore_type, Datastore_Capacity_GB
  $row. Datastore_name = $_.name
  $row. Datastore_type = $_.type
  $row. Datastore_Capacity_GB = [math]: tour ($_.) Capacity / 1 gb, 3)
  $row. Datastore_Freespace_GB = [math]: tour ($_.) FreeSpace / 1 gb, 3)
  
  $ReportDatastore += $row

  }

  END {$ReportDatastore}

  }

  Any ideas on how to do this?

  Thanks in advance

  Eirik

  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
  }
  else{
  # Wrong object type
  }
  

• Data store is not mounted automatically after updating the Firmware of the LSI

  I've recently updated the card RAID LSI firmware on my ESXi 5.5 system (patched and update top of page)

  When I rebooted, took place the following:

  1. the associated VMFS volume RAID was mounted

  2. the data on the volume store was not mounted

  I mounted the data store manually and restarted my VMs

  Do I have to re-signing the Volume and/or the data store to raise it properly.

  Steve

  The command should be ok and do the same thing as the command esxcli esxcli storage vmfs snapshot mount -l label|-u uuid (for details, see http://kb.vmware.com/kb/1011387).

• Script in time of latency list vm e/s and the data store the virtual machine is on

  Hello.  We have a vsphere 5.0 environment and we live a latency of IO heavy.  I'm looking for powercli script will get the latency of i/o for each virtual machine and get the data store name, to what it is now.  We will access our storage on optical fiber.  I'm trying to get a good overview of the latency of IO in a nice view in a csv file.  I found what could be a good basis to https://communities.vmware.com/thread/304827?start=0 & tstart = 0 , but I'm not sure how to get the name of the data store in the table and I think that it is written to the nfs in any case storage.  Thanks in advance for any info\advice!

  Try the next version, it includes the average latency time read/write for the virtual machine and PAHO are / s average for the virtual machine.

  Since the CSV has a row for each data store, the values for the virtual machine are repeated.

• How long does take to dismantle and re-scan a single data store

  Hi all

  I am currently using vSphere 5.0 to manage 3 x 5 ESXi hosts. I am trying to use the host VM 2 for surebackup data store and virtual laboratory of Veeam. I had already used the same data store and removed. Now try when I set up again on the same data store, it generates the error Create NAS Datastore - specified key, the name or the identifier already exists.

  After reading about the issue, I've seen the way to solve this must dismantle and Reanalyze the data store that produces the error. As I've never done this before that I was wondering if someone could share their own experiences? I need to move the exisitng s VM from the data store before I have to dismount and perform a new analysis or any point throughout this process?

  Some details on the data store:

  Composed of disks SAS 4 x 300 GB in RAID 5 with a total of 831,50 Gb. There are 8 VM running on this server using 400 GB on the Go 831,50. 4 virtual machine are essential and must be operational during the time leading to opening (9 - 5.30 pm). These total 222 + 39 + 33 + 69 = 363 GB. The data store is not shared between hosts.

  The migration of virtual machine for the other guests, I'm able to estimate (if necessary). What I'm really interested in is the length of time that it will dismantle and Reanalyze the data in question store.

  Any help would be much appreciated.

  Thanks in advance.

  Kind regards

  Haydn

  You must move the virtual machines before you take it apart

  or close the virtual machine and to unsubscribe to esxi.

  given that the data store is not shared, you must do the migration of data store for virtual machines such as migration cold.

  Disassemble and analyze new shouldn't take more time, let's say less than 2 minutes if each works fine.

• VMotion and mobile readers of other data stores

  
  We are new to VMware and wonder if it is possible to move a single of a disk HARD virtual is in a different data store to customers? For example a customer server that has an operating system drive and a data reader. We built a data store of "The OS" on our storage a data store 'Data' and an ISO data store for the operating system and other ISO images. When customer's server has been built the disk 'Data' has been accidentally placed on our database 'ISO '. So is it possible to simply move the drive of customer data from the data bank "ISO" to the court to erase the disc and recreate in the correct correct store? Looking at the vMotion options in the client web it seems that if we pass a 'reader' we go together or have I missed something?

  Hello

  You must click on the button Advanced settings in the wizard for vMotion to the point where you choose the target. You can set a separate objective for each single VMDK (and the VMX file)

• What is a relationship between the data store and LUN?

  Hello

  I added 3 LUNS to a data store, but I can't list them since the MOB data store. Could someone tell me how to do it.

  Thanks in advance.

  Lee

  LUNS was formatted as VMFS and created a data store? If not, it will not be displayed. You can search for available LUNS that can be used to create a VMFS with QueryAvailableDisksForVmfs volume

• Ghost in a data store VMs

  Hello;

  I need to remove a database on my ESXi 5.5 HA/DRS cluster due to storage issues.

  VCenter watch 3 VMs running in the data store but it is not a correct information. Vcenter also shows that space 0 B used for each virtual computer. So vcenter won't let me not disassemble the data store. When I look at the parameters of each virtual computer, these virtual machines running in a different data store.

  When I try svmotion, it says completed successfully but VMs are still stuck in the data store.

  Can I turn off all 3 VMs, remove/remove datastore and turn on those virtual machines, but I find that it is so risky. Because these virtual machines are essential and hundreds of GB.

  How can I remove the data safely store?

  Thanks and greetings

  Tirelibirefe

  First of all, check if one of those VMS have any ISO mounted this data store... and even if it there is no ISO standard not mounted, check if there is place of the snapshot on the virtual machines and delete them, cause maybe the ISO was mounted when the snapshot was taken.
