• Connect to multiple instances of a script vCenter?

  How can I connect to multiple instances of a script vCenter without going through separate-entry sequences of credentials or credentials on disk storage?

  I need to browse through a table of the vCenters and run scripts against each of them. They are not related, but the same credentials must be valid on all instances.

  It would be great if there was also a way of parallelization of this job such as each returned only thread STDOUT is it speeding up the script.

  All suggestions are welcome, I can see some tips using PowerShell, but I need to do it in Perl.

  Thank you

  You get close, you are missing just a few required modules. Here is the final excerpt that will work for you:

  use strict;
  use warnings;
  use VMware::VILib;
  use VMware::VIRuntime;

  {eval
  My $vim = Vim::login (service_url-online $url, user_name => $username, password-online $password).
  My $vms = $vim-> find_entity_views (view_type-online 'VirtualMachine');
  {foreach(@$VMS)}
  Print $_-> name. "\n";
  }
  };
  Si ($@) {}
  Print $@. "\n";
  }

  Make sure you put things highlighted in bold, it's what you have in your Perl script. I checked on the VMAs, but I'm sure it'll work on Windows as well.

  You're right, the documentation can be better... If one of the reason, VMware has created all these routines support auxiliary, is to abstract the complication of the API. They also assumed that you'd be connectingn to a single host or vCenter simultaneously. All that falls on these basic configs, it will take your own code/etc. and where watching is that the first part of the challenge

  Good luck

• Multiple connections to ESX

  Hello

  I'm creating an application web multi-threaded, the job of managing the work of automation running on an ESX Server. When 'jobs' was presented, the system manages execution of each task on a VMWare ESX server image. I use the wrapper "Vestris.VMWareLib" of dblock in c# to perform these actions.

  However, I have some problems when I try to connect to ESX. If I try a number of connections to ESX (like when the 3 jobs carried out to run) at the same exact time in my application, I get the error:

  Vestris.VMWareLib.VMWareException: The handle is not a valid object of VIX

  I've then preceded to write a simple c# console application make 5 simultaneous connections to ESX, but had no problem with these. I have attached to this example.

  I have some questions if I do a number of connections to ESX at the same time? What is an idea that I have to "shift" for connections by a couple of seconds?

  Please help thank you!

  I asked the same question several times on this forum (http://communities.vmware.com/thread/214215) and I'm not the only one. I tried other channels in VMWare and I have nothing but radio silence.

  Update: this thread, http://communities.vmware.com/thread/205942?tstart=0, said he's going to be a release in a few weeks. I cross my fingers.

• 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.

• Is it possible to use GPFS or another build is a SAN storage shared for multiple ESX and ESXi hosts?

  We have a license GPFS and SAN storage. I am trying to create a storage shared for multiple ESX and ESXi hosts share existing virtual machines. We tried once NFS, it of a little slow and consume too much bandwidth LAN.

  Anyone can help answer? Thank you very much in advance!

  It depends on your storage space.

  You must connect all hosts to the same San, then follow the configuration guide of ESXi and specific documentation for your storage space (for sharing LUNS on multiple hosts).

• Multiple ESX servers to access the same data store

  We connect our ESX servers to an Equallogic SAN iSCSI using VMWare iSCSI card.   I have a data store that has ISO files to store.   So far, I can connect only this data to an ESX Server store on time.  I have to disconnect an and connect manually to the other.  We currently have a facility relatively bare bones (don't have vCenter again, grouping, etc.).

  Is there anyway to connect the same data store to multiple ESX servers?  I tried to adjust the volume of Equallogic SAN for read only (since I just need to read ISO files), but I can't connect to ESX servers when I do this.

  Remember that the volume is enabled for clustering.

  From v4.x Equallogic firmware, there is an option advanced on each volume.

• It is supported to connect multiple monitors using USB as a video source?

  Original title:

  USB touch screens

  It is supported to connect multiple monitors (specifically wireless) using USB as a video source?  If so, a hub would be able to handle this or the USB connection should be made directly to the motherboard or the PCIe interface.  Thank you!!!

  Hello

  Thanks for posting your query in Microsoft Community Forum.

  You can buy a switch HDMI that allows you to connect several devices to sources HD (e.g., monitors, TVs etc.) to your computer, while using only one cable HDMI (VGA or DVI) of your computer to connect to the second monitor. So you can get a HDMI switch on your favorite search engine for compatibility information for the switch with Windows 8.1.

  If you want to project, or sharing of the wireless display, you can use the utility Miracast.

  See also the article below to better understand.

  Plug a second monitor or projector

  Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

  Thank you.

• Make a single LUN can be used by multiple ESX hosts

  Is it possible for a single LUN to be made usable by multiple ESX hosts at the same time?  For example, if you have an image or used by a vSphere environment requiring other vSphere environments in the data center access, you can put the image on a storage place where completely separate ESX hosts vSphere environments completely separate can see the same lun and clone the image or necessary?

  If the logic unit number is locked by accessed by an ESX host will be lock expires when the ESX host is not an another ESX host in another environment vSphere allowing access to the logical unit number, or is the lock, as it is usable by a single ESX host, until the storage is reconfigured to make it usable by a different host?

  Is there a better solution to this scenario?

  Thank you

  You can deploy both at the same time.  Locking occurs only for changes to metadata and only for the shooting of subsecond.  It is not required for the entire deployment process.

• Connect an ESX host 4.0 in a store of data VMFS 3.31 with vMotion, and ESX 3.5 hosts

  Hello

  I moved 2 x a new vCenter 4.0 3.5 ESX hosts.  I also have a new ESX 4.0 host.

  Can I connect this ESX host 4.0 for the data store using the 2 x ESX 3.5 hosts?  It is a VMFS 3.31 on a CX3-20 SAN data store. I was then going to vMotion virtual machines to the new host and reinstall the old.

  I just fear that the new ESX 4.0 host will do something to the data store that make it incompatible with the older ESX 3.5 servers.

  Thanks in advance,

  Euan

  Yes, you can connect and use these data with ESX versions warehouses. If you have sVMotion it will work as well. On ESX 3.5 you can only move the guest as a whole on an ESX 4.0 host, you can move the vDisks independently.

  It is perhaps unnecessary, but when I update the ESX 3.5 servers 4.0 I unplug the storage until the update is running. Just in case...

• After that I changed the Duplex parameter on NIC's Service console, I am not able to connect the ESX host

  Hi all

  Please help solve my problem.

  After that I changed the Duplex parameter on NIC's Service console, I am unable to connect the ESX host. How can I reset the 100 MB NETWORK card duplex. Can someone help me please.

  Concerning

  Vijay

  Hello

  As the bulb you have two problems that are not related.

  (1) duplex setting, your switch and NIC must match. If one is assigned to auto-negotiation, then the other must be set to auto-negotiation. Personally, I tend to let auto-negotiation unless there is an absolute reason to spend. If you then turn on the both sides of the interface, the switch port and esxcfg-NICS allows you to change the duplex, etc.

  (2) passwords for root are not related to the network unless you have also run esxcfg-auth authentication remote.  The only time I saw what you have here is when the system is configured to try to authenticate remote and not locally.

  The two problems are fixable by booting into single-user mode, set the duplex and reset the password.

• LabVIEW - Arduino TCP/IP, connecting multiple Clients

  Hello

  I'm working on a connection TCP/IP between an Arduino shield WIFI control with several sensors and a LabVIEW program. You use a router, I set up a wireless network without internet that allows me to transmit the readings from the sensor of the MCU and send commands to control LabVIEW program. Currently, the Arduino is the server with the program LabVIEW connects to it as a customer and I would like the opportunity to add other clients such as a smartphone application at the same time. I am not able to connect several clients for my server Arduino based and wonder if and how this would be possible if the server was created on my computer using LabVIEW instead.

  I searched for help on the Arduino forums (http://forum.arduino.cc/index.php?topic=268578) and comments ranged from "Arduino can support multiple clients" to "Arduino can support multiple clients but it is full of errors. While it would be easier to achieve my goals by having the server on the MCU, as much data would be sent directly to each poll, the client I plan to switch to a server on computer using LabVIEW. My question is whether it would be possible to have multiple clients access to my new server, and if so, how it would be difficult to relay data from the sensor? The old plant requires the same data string for each client connected to my server. The new configuration appears as it would take the server to treat customers differently; Send commands to the MCU customer and data of the sensor of the MCU customer to everyone. Another layer of complexity is that I would need to relay controls of other clients in the same way, as the phone app smart sends a stop test command, to the Arduino via the LabVIEW program.

  Would be very grateful of entry to the community.

  Best,

  Yusif Nurizade

  You can create a server in LabVIEW that accepts connections from several clients. There are examples of different approaches to this in examples of shipment of LabVIEW and on this forum. As for the challenge of sorting where to send the data and how to transmit orders, it is-there is nothing that would make whether easier or harder in LabVIEW that in any other environment.
