• Script of PowerCLI to capture ESXi host CPU & memory

  Hi all

  I'm having the time more difficult to find a script that will give me ESXi host CPU and memory. I just need something simple, if there is such a thing?

  Example of what I'm looking for:

  Host name	Ability of GHz CPU	CPU GHz used	Free GHz CPU

  Host name	The memory capacity	The memory used	Free memory

  Help, please.

  You mean like this

  Get-VMHost-name MyEsx |

  Select Name,

  @{N = 'GHz CPU capacity'; E = {[math]: tour ($_.)} (CpuTotalMhz/1000,2)}},

  @{N = "GHz CPU used"; E = {[math]: tour ($_.)} (CpuUsageMhz/1000,2)}},

  @{N = "CPU GHz free"; E = {[math]: Round (($_.))} CpuTotalMhz - $_. {{(CpuUsageMhz) / 1000,2)}}.

  @{N = "GB memory capacity"; E = {[math]: tour ($_.)} (MemoryTotalGB, 2)}},

  @{N = 'Memory used GB'; E = {[math]: tour ($_.)} (MemoryUsageGB, 2)}},

  @{N = "GB free memory"; E = {[math]: Round (($_.))} MemoryTotalGB - $_. {{(MemoryUsageGB), 2)}}

• ESXi host and VM hardware upgrades

  Hi all

  I pretty well know the answer to these questions (I like to read manuals), but I just wanted a few reassuring those who have ventured in front me.

  1 / when the upgrade to ESXi hosts of 3.5 to 4.0, it is my understanding that there is no real emergency in the upgrade of the host of the virtual computer (tools and hardware to version 7) as vSphere 4.0 will run happily with the older virtual machine (but without the new features).  However, I am wondering if anyone has experienced problems do not upgrade the machine virtual shortly after the upgrade of the host.  My intention is to do it very shortly after, but sometimes the best-laid plans go out the window in my role, so I'd feel comfortable if I new I could run the old VM indefinitely without any problem.

  2 / how 'security' is upgraded version of the VM from 4 to 7 material?  VMware I don't expect any problems, but I would like to know if anyone has experienced problems that can cause interruptions of service extended to the VM guest.

  Thanks in advance,

  Steve.

  1. I would separate between VMware tools and hardware upgrade. New tools not only to upgrade virtual hardware drivers, they also inflating to update and other features VMware uses to communicate with the guest operating system. In my opinion, you should pass the VMware tools as soon as possible. I can't say for sure if you have any questions without upgrading. My personal opinion/experience, is that during the "normal" old tools will.

  The hardware upgrade should not too important. In environments with hundreds of guests, you will actually have to update all hosts (in a cluster) material in order not to lose the capacity of invited guests 3.5 vMotion.

  2. the only issues I've had so far with the upgrade of the hardware have been networked. I had a few VMs to reconfigure the network manually after the upgrade.

• Connection usb to esxi host and copy vmdk

  Hello

  I'm trying to migrate a vSphere cluster to another machines.  There is no network connectivity between the 2, so I intend to copy the files vmdk and vmx more via USB directly connected to the host for thoroughput max.  Anyone tried this?  I looked in the documentation and online, and I see that the only supported file systems FAT32 and ext3.  For a 40 GB virtual computer, can I use an ext3 formatted USB key, copy locally and then USB attach themselves to a host on the new cluster and copy?  Anyone see any problems with this?  We are doing this process via a USB port connected to a position of the user and SCPing between the host and the USB port on the network.  I think that cutting the transfer network will speed up the process, currently a 40-50 GB VM takes about 3 hours

  Hello

  I understand that you can read in what she argued, however...

  If there is a KB article while this does not mean that it is supported, it simply means that it is possible and you might be able to use it if the need is high enough. For example, in case of problems you can risk some stability/performance and fix the most urgent problem at hand, as a critical VM that was on a LUN which disappeared earlier that day there so that you only restore backup on a USB drive.

  Also note the supplement "additional note" at the bottom of the KB that you are facing

  Quote (my highlighting):

  More information

  The USB key must be a minimum of 4 GB in size. This procedure is not recommended for basic file transfers.

  This procedure includes steps on disabling the intercom USB host function. Then earlier in the article that they use the same feature to connect the USB drive to the guest.

  If this isn't everything, they use the DCUI for mode of tech support that their link in an article KB1017910 to using the console is already a bit dodgy on a production host. About using the console for day-to-day operations is a no No

  Another quote, this time from this KB article, underscores once again with me.

  Tech Support Mode

  Tech Support Mode (TSM) provides a command line interface that can be used by the Administrator to troubleshoot and correct abnormal conditionson hosts VMware ESXi. TSM is accessible in two ways:

  • Connecting directly to the ESXi Server console.
  • Remote SSH connection.

  Further down in this article, it is pointed out again that it is for support only, I would say is something different as 'supported environment.

  It does not mean that you can not and never use should the DCUI, but be careful.

  Back on the focus to what you're trying to do.

  If your USB drive is broken, you now have a hypervisor that attempts to mount it to the level of the hypervisor, which, in itself, can cause downtime at the level of the hypervisor risks of release for ALL your guests. USB transfer at least maintains these problems located in the virtual machine, it is attached to.

  Besides that... the only system files that you can mount is VFAT, so you can't even put files there that are larger than 2 GB (or 4 GB) in size.

  File systems ext2/ext3/ext4 that none of those who are supported, VFAT only for your external USB drive.

  Yes there are ways around the VFAT file size limit too, but you're just jumping through the next pole, and if something's not going then your users is satisfied by the retoric "but backups are faster".

• go esxi hosts and virtual machines in one vCenter to another

  I built a new vCenter (Windows vCenter), I intend to move on ESXi hosts the old vCenter (Virtual appliance vCenter) to the new vCenter. I don't know if it's feasible, please notify my step is correct or not: 1) build a new vcenter 2) create a cluster with two esxi hosts first 3) Mount data (NetApp Filer Storage) to the new vCenter warehouses 4) add an empty host for the new vCenter VMs) 5 download then upload to the host in new vcenter

  Hi friend

  Its doable without any problem.

  Please follow the procedure below.

  1 build a new vCenter (your first step is correct)

  2 creating a cluster (because it is new vCenter there will not be any available host.) That is why cluster creation wizard will not get to add in the new cluster host). While initially empty cluster would be created.

  3. once the cluster is created, immediately do a right-click on the cluster and add your hosts one by one. Not necessary to cancel the registration and the VM. Virtual machines will automatically be added who were there on the data store available with all guests.

  Don't forget,

  1. we do not mount any store data in vCenter, we assemble the data store on the host.

  2. If you mount the new data store (which did not exist before), you can mount once the new hosts are added to the new cluster. (Your SAN admin help)

  3. If you want to move your virtual machines from data store before the newly added/mounted data store, please SVMotion these virtual machines (by right-clicking on the VM > migrate > data store > select the data store that is new)... Please follow the same procedure for all virtual machines.

  4. you don't need to add empty hosts to the new cluster, add just as soon as all guests without you register VMs. Later, you can migrate to other store of data according to the requirement. NO need to download or download the VM.

  5. Please make sure that your ESXi hosts will be compatible with the new vCenter. Old version of ESXi always compatible with the new version of vCenter. Just check if you have all valid licenses.

  Please let me know if you need any clarification

• Nested ESXi hosts and iSCSI POC

  People,

  I want to set up a proof of concept for a two host, two models NAS for my workplace. At this point, I put a host of ESXi nested using this Vcritical guide - http://www.vcritical.com/2011/07/vmware-vsphere-can-virtualize-itself/

  This made wonder. I have two virtual servers within the main install ESXi with the three hosts on the network 192.168.0.x. I then added a second NETWORK adapter on the 'server' and separated from the network iSCSI (192.168.1.x) and pointed to a simple NAS. This went well now. The problem is the hosts nested cannot access the iSCSI network.

  It's all a bit above my paygrade, but I can't work on how I can get the hosts nested on the iSCSI network. I tried to add network cards second in virtual computers running virtual hosts and their allocation to the 192.168.1.x network.

  Can anyone help to shed light? Someone you will understand my question or what I'm doing? I hope so!

  Thanks in advance

  HP

  Hello

  Your primary host see the iscsi network and connect to your nas Server?

  It should just be a case of creating a VM portgroup on this same vswitch, with settings of appropriate VLANs if necessary, assigning your esx hosts nested this portgroup vNIC. On the nested hosts themselves, you will need to implement the initiator software iscsi etc. as usual.

• List of ESXi host and data managing paths

  can someone help me with a script to list the ESXi host name, then their data management of path for each data store that they are connected to?

  Thank you

  MikeP

  Sorry, I thought you ment the other script.

  Try it like this

  Write-Host "Connecting to vCenter" $VCent = "10.2.160.250" Connect-VIServer $VCent -user user -password passwd $VMHosts = Get-VMHost | Sort-Object Name Disconnect-VIServer -Server $VCent -Confirm:$False 
  
  $report = @()
  
  ForEach ($VMHost in $VMHosts)
  {
      $HostName = $VMHost.Name
      Connect-VIServer $HostName -User root -password passwd    $esxcli = Get-EsxCli  -VMHost $HostName    $esxcli.corestorage.device.list() |
      where {$_.IsLocal -eq "false" -and $_.DeviceType -eq "Direct-Access" -and $_.MultipathPlugin -eq "NMP"} | %{
           $report += ($_ | Select @{N="Host";E={$hostName}},Device, MultipathPlugin)
      }
      Disconnect-VIServer -Server $HostName -Confirm:$False}
  
  $report | Export-Csv "C:\report.csv" -NoTypeInformation -UseCulture
  

  You can try to change the Where clause to see all the plugins multipath.

      where {$_.IsLocal -eq "false" -and $_.DeviceType -eq "Direct-Access"} | %{
  

• Attempt vSwitch configuration change and now the ESXi host and virtual machines offline

  So I have no doubt, I have myself to blame for this one. I was trying to change my vSwitch from 100 Mbps to 1000 Mbps when an 'operation timed' error out jumps-to the top and my vCenter Server lost connection with my ESXi host. I tried to restart the host manually, but that did not help. The host is not the ping requests and all the virtual machines on that host are offline; None of them vMotion off to my other ESX Server.

  I tried to reconnect the host computer in vCenter, but it is obviously does not connect because it can't ping it. I logged the ESXi console and all the network settings appear to be correct. I'm used to connect to the ESX console where you can execute commands, but it's my first ESXi host, so I don't know what I can do.

  Any help is greatly appreciated!

  -D.

  If you had your management port and VMs on different vSwitches / NIC leave on framework would eliminate a false positive. As in your case the management port reportedly follows the cable / about speed, but the virtual machine network would be intact (and I'm assuming that your storage space as well).  In this case the VMs system would have worked very well even if the management port did not work.

• Several ESXi hosts and need to share virtual machines

  I'm relatively new to ESXi (although a lot of vSphere, using iSCSI storage) and we are making a number of servers in remote site (with a proxy and utility VM to manage the file/print/dhcp) using ESXi. I have my VMs built on the first box and need to copy them off the coast to the other, but I have problems with the command ADD Storage... I can't seem to get the right information and I begin to think I'm missing something basic. Then...

  (1) can map you to the VMFS from another host esxi?

  (2) If you can, where do you find the location on the second machine information to set up the data store on the first machine?

  If it's important, we use Dell PE of the 1950s.

  Also, while I'm here...

  The size of a pain is to change the IP address or the name of the ESXi host area?

  Thanks in advance for any help!

  VMFS is not supported on USB drives.

  You can use FastSCP for example, http://www.veeam.com/vmware-esxi-fastscp.html

  And Yes, there are several devices that could share storage attached to the network locally, but I don't see them as a solution when you want to just copy existing virtual machines to another host ESXi.

• How to backup 4 ESXi host and guests?

  Instead of running 2 or 3 physical servers, I create 2 or 3 virtual servers on one physical host and save money, the trees, the planet and so on.

  Go green, as they say.

  But how do I save it?

  My first experiences with VMWare workstation (excellent product BTW), I thought that I could connect an external hard drive on the physical server via USB and back up virtual machines from time to time. Just as I could with VMWare workstation (not to mention the snapshot option...).

  Right...

  Indeed, virtual machines in case more than one front-end role rather than the portfolio databases that change on an hourly basis, an image on an external hard drive backup were possible.

  But it doesn't look like it works that way with ESXi.

  OK, the snapshot option is still there, so that offers backup features (update mess up system, go back to the last good snapshot).

  But when I connect the external hard drive, it is not recognized. Sounds fair?

  I heard that you could back up via iSCSI. Possibly using the software to create an iSCSI target on another server instead of investing in a unit of SAN.

  Despite this, where you re all or part of this?

  I don't see no backup option in the interface of vSphere 4.

  THS, that's what I have:

  X3350x IBM server | ESXi 4 | 1 guest running Windows 2003 server and the other running 2008 Server.

  That's all. No VCenter, no vMotion, no second failover server.

  Could someone clarify my options?

• Affinity reserve esxi hosts and host rules

  I'm trying to reserve a few for some special VM ESXi hosts, I used affinity DRS rules to make the virtual machine to run on special guests, but other virtual machines are also coming on ESXi hosts reserved because of the DRS.

  I have about 300 virtual machines running on 10 ESXi hosts running VMware 5.0 Update 2

  Currently using Vcenter 5 Update 2

  I have just installed 3 new hosts ESXi running the same VMware 5.0 Update 2

  The new ESXi 3 hosts must be temporarily reserved for a project with 30 new VM only, but always be part of the main cluster because they will be used with the 300 existing virtual computer when the project is completed.

  I have a rule configuration of affinity for the new virtual machine only works on the new ESX hosts

  But the problem is that some of the other 300 vm get Vmotioned with DRS on the new hosts as they have a lot of free resources.

  There are new virtual machine being added to the VM s 300 all the time by other people that I can't control.

  I'm happy to manually add my special project of the virtual computer to the rule of the DRS of affinity for the reserved ESX hosts can not have "other persons" manually add the new virtual machine to another rule, should it be automatic for them.

  I would like to set up a global rule to tell if you are not a virtual machine in my special project group DRS that you are not allowed to run on the 3 new ESX host.

  Dose anyone know if this is possible?

  Why not move the hosts in a cluster instead?

• Access the SMB storage using esxi host and manage with MS server 2008

  Hi there, I know the subject line can be confusing, but I didn't know how to explain what I need in the line object in such a short sentence.

  in any case, I have a storage device SMB, a Promise VTrak M610P, which is attached to a blade server 1U HP through interface channels double Ultra 320 SCSI host. I can't configure the VTrak as a NFS, the only way to access logical drives is connected to a server via the scsi channels and using the operating system to share the drive and the shared disks.

  I would use a server blade with dual ultra 320 SCSI host interface channels and connect the VTrak to this server blade. Then I would install ESXI hypervisor OS 5.5 to this server blade. I want to know is if the ESXI operating system will recognize the logical drives and if I create a virtual machine with MS server 2008 and see if the virtual machine detects logical drives, so that I can share the drives? I hope that I'm supposed to and if I'm not, please let me know what makes no sense, I will do the best to explain it better.

  Thank you

  Andy

  So it turns out that there seems to be something wrong with vClient when you add a hard disk (virtual disk) to a virtual machine of size greater than 4 TB. Article VMware KB: value of range error message when you add more than 4 TB capacity discs in vSphere Client describes this if you encounter this problem, add the hard drive via vSphere CLI, CLI power or vmkfstools. So this seems to be a known issue on vClient. What I ended up doing was using vClient, creation of hard disk, adding to the virtual machine (size of the hard drive is to 5.45) and when I would get the error message on the DiskCapControl out of reach, I would just click OK and then finalize the creation of the hard drive on the virtual machine. Once the process is complete, I selected the virtual machine and noticed that he indeed added a new HDD size 5.45 TB even if he's complained about it. I pulled to the top of the virtual machine with windows server 2008 R2 installed and was able to create a new disk under windows and set it up as a shared drive on the network. Looks like vClient must be updated by VMware and correct this bug, if it's a bug that I think. Thank you for the help vervoort!

• Setting up iSCSI between ESXi host and MD3000i, firewall Option missing

  I try to configure the iSCSI access and the MD3000i manual head to the firewall option in VI Client.  However, when I go to Configuration - & gt; Profile of security - & gt;  the option firewall appears briefly and disappears?

  I'm having problems to recognize the iSCSI host table and I think that this may be due to the firewall.

  Hello

  I believe that in the latest versions of ESX (3.5u3 for sure), 3260/tcp port (you need for iSCSI) is automatically opened when you turn on the iSCSI (iSCSI software that is).

  You should choose abe to connect using the VI client, click the host in question and select the 'configuration' tab and then the item "security profile. Who should be open all ports.

  Remember that when you use iSCSI, you must as well a VMkernel port and connection of console in your LAN IP storage space. If two IPs per ESX host. The Console launches the iSCSI link, the VMkernel carries the iSCSI connection data.

  EDIT: Sorry, only now I noticed that you are using ESXi. In this case, you won't need a port Console service (because ESXi has one)

• host 32-bit with 64-bit hosts and memory usage?

  I use 32-bit Microsoft Windows Vista Business SP2 as a host Workstation 6.5.

  No, unfortunately it turns out that it is impossible. You will not be able to see more than the 4 GB, unless your host operating system is able to see the memory using a PAE switch, or by using a 64-bit host OS. As Vista does not support the PAE switch, your guest operating system will be limited to the 4 GB as the host OS.

  If the host operating system is 32-bit, 64-bit guest OS can be created?

  Yes it is certainly possible. But you must make sure you enable VT-extensions. See also the excellent article by jmattson on troubleshooting problems of Intel VT - x
