• Impossible to mount any NFS data store: unable to resolve host name '< obsolete Server > '.

  Hello

  On a particular ESXi server, whenever I try to mount any NFS data store, I get this error message:

  Call "HostDatastoreSystem.CreateNasDatastore" of object "ha-datastoresystem" on ESXi '172.22.216.64' failed.
  Operation failed, the diagnostic report: unable to resolve host name 'cosmo '.

  Always mention hostname 'cosmo', no matter what server I'm actually trying to mount. 172.22.216.64 is the exact address of the ESXi server.

  'cosmo' was the former name of a desktop linux machine, several months ago has re-installed and renamed in the process. So 'cosmo' is no more and it's just expected that 'cosmo' cannot be resolved. However, the error message mentioning 'cosmo' occurs regardless of what server I try to mount a NFS datastore of. I can't find any references to 'cosmo' in the ESXi server configuration in the vSphere client (although I don't know exactly where to look). I remember that at one point, a NFS datastore was mounted temporarily to 'cosmo' to host the ISO debug files. But no more.

  I tried this same sharing of an another ESXi (running the same version of ESXi) mounted in the same subnet (works great), and I also tried to mount a new NFS share on a server where the ESXi already had another NFS data store mounted from the same server (the data store already mounted works fine (, but attempts to connect to a new data store on the same failed server mentioning the independent 'cosmo' server as mentioned above). I tried to restart the ESXi server, but the problem persists after restarting.

  I'm under vSphere client 5.0.0 Build 455964 and ESXi 5.0.0 - 469512-standard with the free license. Because of the free license (I think), I don't have SSH access on the server. (Is that right?)

  How to work around the error message mentioning the obsolete server 'cosmo '? The only thing I can think of right now is to move all data from the local data store to a store of data already mounted, reinstall the ESXi server and give all the data. I'm hoping for a simpler solution! :-)

• Add several NFS data stores to multiple ESX hosts

  I am trying to write a script that will set up several NFS exports to multiple ESX hosts. Here is the script I use, it will add an NFS export to an esx host list.

  $esx = (get-Content servers.txt)

  {}
  $Host_Name = (Read-Host "enter the server (ex: storage-san)")
  $Path = (Read-Host "enter the path (ex: / ds_name/flight/flight)")
  $Name = (Read-Host "Enter the name of the data store")

  {foreach ($server in $esx)
  $Error.Clear)
  Get-VMHost $server | New-Nfs Datastore - NfsHost $Host_Name-path $Path - name $Name | Out-Null
  If ($error.count - gt 0) {$error | out-file ($server, 'c:\powershell scripts\logs\' + '.txt')}
  }

  $add_more = Read-Host "want to show you another data store?
  }
  While ($add_more - eq 'Yes' - or $add_more - eq "y")

  This script actually works OK but I can't just she kick sending and walk. If I have 10 stores of data to add, I have to wait for the current to the end, and then type the information for the second, etc..

  I was hoping just to type all the information from the beginning and the shot of the script to the wide and let him go. Here is what I added, you can see where I'm going with this?

  $esx = (get-Content servers.txt)

  $num_mounts = (Read-Host "Do you have multiple media")
  If ($num_mounts - eq 'Yes' - or $num_mounts - eq "y")
  {
  $mounts = @(Read-Host "supports différents combien avez_vous")

  #prompt me for all the different right monte upwards before and then executed by the actual task of Mount...
  }

  Any ideas?

  Try something like this

  $servers = @()
  $paths = @()
  $datastores = @()
  
  $answer = Read-Host "Enter another NFS mount ?" while($mount -eq "y"){
      $servers += Read-Host "Enter the NFS host"    $paths += Read-Host "Enter the path"    $datastores += Read-Host "Datastore name ?"    $answer = Read-Host "Enter another NFS mount ?"}
  
  $Error.Clear()
  
  Get-Content servers.txt | %{
      $esx = Get-VMHost -Name $_    $countNFS = $servers.Count
      if($countNFS -ne 0){
          0..($countNFS - 1) | %{
              New-Datastore -Nfs -NfsHost $servers[$_] -Path $paths[$_] -Name $datastores[$_] | Out-Null            if($Error.count -gt 0){
                  $Error | out-file ('c:\powershell scripts\logs\' + $server + '.txt')
                  $Error.Clear()
              }
          }
      }
  }
  

  The script reads all the data in the tables.

  Then it loops through all ESX hosts from the servers.txt file, and for each host, it will create all the NFS data storages.

• Can NOT see the data store after ESXi update host?

  Hi all

  We use the host ESXi 3.5 on DELL PE 2850 with RAID 5 local storage.  Today, I ran utility update for the host VMware and firmware updated BIOS and RAID on the host computer before a restart of the system.  After the reboot, the system correctly loads the operating system and when I check for storage, the data (with critical VM) store is missing.  Can not see that again.

  Please help me to recover my data with the virtual machines in her store.

  Thank you

  Nadine

  ESXi is installed on the same Partition RAID 5, which is located in the VMFS data store? for example. do you know that the partition is still intact?

  According to what the RAID firmware upgrade has done, it is possible that you may need to set the LVM. EnableResignature option 1 if the score ended with a new UUID.

• Connect the ESX host and data store on another ESX host

  Hello

  assuming for this scenario:

  Host ESX 1: esx1

  Host ESX 2: esx2

  It is possible to mount esx2 datastore in esx1? (For example: via NFS). Of course, it is possible use a NAS/SAN intermediary, but I wonder if it is possible to achieve a direct mount.

  Thank you

  Eddie

  Well, to allow another host to share the local data store, the host must be able to act as an NFS server. The problem is, there is no service in one of the ESX version which able to serve that. So, as said what a.p., no, is not possible.

• Create a second data store or expand an existing for a second guest data store

  Hello

  I want to create a second guest in an ESXi environment with two hard drives. Currently a single guest runs on the first store of data on the hard disk of the first. The second hard disk is attached and I should expand the existing data store or create a new data store. Is performance better if each client runs on his 'clean' hard drives or is there no leak performance if I extend the first store of data.

  Kind regards

  Axel

  Hi Alex

  Because of course you need to better performace on your virtual machine when each of the virtual machine would work on the separate data store that is created on the separate physical hard drive. Is visible only in the DISK operation.

  A question, does your env test or production?

• How can I add a data store as an additional drive for a virtual machine?

  This is probably very simple, but honestly, I'm quite a n00b when it comes to networking and sys. Small business being at low cost...

  OK, I have a HP DL360 G5 running ESXi 3.5 with 2 virtual computer management. The first is a cloned Win 2003 SME (I had to save the last days of server primarily was about to fail), the other is a Win XP VM (which is just share a single file to 6 users)

  The server currently has 2 x 73 GB 10K SAS RAID 1. I installed another drive of 73GB 15K and seen in V: IC, I can add the storage, but how the VM of 2003 to see the new disk space? I need to be added as an extra, (e) disk in this case.

  TBH I don't know even if I added the next Assistant in V: IC correctly except extra storage space.

  Any help will be appreciated

  If the new drive has been formatted as VMFS3, then you can just change the settings of the virtual machine and add a disk.  Specify the new drive as the location for the new virtual hard disk.  You have two options on this screen.  Store with VM or specify the location.  You will need to specify the location.  Then, you can specify any size you want the new E reader to be.  Then in Windows, open disk management to complete the process.

  This will be your easiest route.

• Move the location of the VM swap file in another data store

  Hi all

  Was in a task to move the 1000 to the file location of VM swap on another data store which is newly assigned to Exchange us to the existing store database file that will be decommissioned.

  Eager to check if anyone has made movement swap of VM location of the files to a data store to another and that all measures taken to move.

  Require some VM downtime?

  Thanks in advance a ton.

  Yes it is possible without interruption of service to virtual machines.

  1. make sure that your cluster is configured to use swap data store specified by host

  2. take a host in the cluster in maintenance mode, change the location of the VM configuration file to point to the new data store

  3. do this for all hosts in the cluster

  When you vMotion a VM from one host to another the swap file will get moved to the new data store. Later when you take guests to the maintenance and return output mode, vMotion occurs for each computer in the cluster virtual and file is moved.

• Creating a new Cluster data store

  Hello

  Can we move a data store in a Cluster of data while its machines store still virtual hosting?  I was not able to find information on this. What I find the Clusters data store talking about new environments.  I'm working on an existing vSphere 5.5 but the storage of data are not grouped.  I want to place data warehouses in a Cluster of quick data without vMotioning store VMS off.

  Thank you

  Boston Tech Guy

  You can move the datastore in the store Cluster data without any downtime, and while VMS are running on it. (This is as same as you put cluster host, while VMS are running).

• Cannot add host to vCenter server as data store is shared with an existing host to vCenter

  Recently, I removed a physical host to a virtual appliance of vCenter Server and am not able to add it to vCenter Server because I get an error message on the existing data store.  I run a simple server vCenter environment with two physical hosts and shared storage.  I've only been administering vCenter for a few months, so I'm relatively new on the technology and processes.  I searched the Internet for a few days now, but have not found documentation everyone has the same problem I have (which I find strange considering the simplicity my problem and configuration), so I tried to get help from the community of VMware.

  I received an error message a day this vCenter Server cannot connect to either of the two hosts so I removed the host (rather than disconnect and plug as I should have done).  Now, I am not able to connect to the host to vCenter server because the shared storage data store comes into conflict with the same data store used by the host in vCenter Server.  I get the error message is ' "Datastore"datastore_name"is in conflict with a store of data that exists in the data center which has the same URL (ds: / / / vmfs/volumes/UUID /), but is supported by different physical storage." "  I try to remove the host data store, but get the following error message: "resource" data store name: datastore_name VMFS uuid: UUID' is in use. ".  The error stack said: "'HostStorageSystem.UnmountVmfsVolume' call failed for object 'storage system' on ESXi"IP address"."  Cannot unmount volume ' data store name: datastore_name VMFS uuid: 'UUID' because the file system is busy. Correct the problem and retry the operation. "I tried to delete all virtual machines of the inventory, put the hosts in maintenance mode, restart physical hosts, but none of my troubleshooting contributes.

  I don't know what steps to take to get this data store driving with the host so that I can add it in vCenter Server.  You can provide me with any help is appreciated.

  Good thing you already moved the VMs on.  For what is 'disconnect', 'remove' or 'delete' might work anyway.  You should maybe put the host in maintenance mode or even reboot the host before you can remove data warehouses.  In an extreme case, I even had to remove the host and the hypervisor installed completely rebuild on the spot.  It is not that difficult or does not take long to reinstall, so be not afraid on this subject.  A clean reinstall could still save time compared to the deletion of data warehouses.

• Add the host Cluster in the Cluster data store

  How can I add host/HostCluster in the Cluster data store after the cluster data store is created. I know that we can add at this time, when you create the cluster data store, but how can we add it as soon as it is created?

  I think that as long as the new host has access to all the LUNS that comprise data warehouses in the cluster data store, then no further action is necessary.

  Make sure just that if using CF then zoning is configured correctly and the LUNS are not hidden from the new host.

  Also, make sure you restart the analysis for new data warehouses on your new host so that it can detect data warehouses

• Strange problem after moving from the virtual computer to a new data store

  I am migrating our VM existing (8 in total) a 'problem' RAID to a new table on a new controller and am having a strange problem. Here are the steps I took (host OS is Ubuntu 8.0.4 LTS x 64):

  (1) off the power the virtual computer from the Web interface

  (2) the directories created for each virtual on the new RAID array computer (in this case a RAID 10 array on LSI 9750-8i controller)

  (3) rSync used to copy the data from RAID1 to be RAID2

  4) has created a new data store on the new RAID through the Web Server of VMWare user interface.

  (5) removed VM of the inventory through the Web, their return, added user interface then choose files .vmx on new data store on RAID2

  They have all power save fine... but three of them are not accessible on the network. I can open a console in the Web Server of VMWare user interface and they all run normally... but I can't their ping or access the respective virtual machine Web GUI. It seems quite arbitrary that those who work and those who are not. In this case... the VM that don't work is a license Autodesk, a Squid proxy server and a VM of cactus. All three of these virtual machines are 32-bit Ubuntu Server VM (two 8.0.4 and a 10.0.4)... and are the only Ubuntu VM on this host. It must be signifigant but I'm not see how.

  If I delete these three virtual machines of the inventory again and add to their original location (on the RAID1) they light up AND work normally. A consultant that we were working seemed surprised, as he had also done this experiment with some of the older VMWare products. I don't see how it would be the physical location of the files of the virtual machine. Any ideas?

  We rely on the migration to ESXi soon but in the meantime, we get these a few VM out of this RAID array problem. I'm stuck.

  Depending on the application, it may be enough to reconfigure the IP parameters (they are very probably on DHCP now) for the newly detected virtual NIC.

• Move a virtual machine from a to another data store

  I ve just added a hard drive on my ESXi server and created a new data store.

  I need to free up space on the original data store, what would be the procedure to move virtual machines within the old data store to the new? (and keep them whitout work break)

  Thanks in advance.

  Facundo.

  to register for a guest, do a right-click on the .vmx file in the data store window and choose 'Add to inventory', follow the instructions
