• vCenter ESXi host reporting

  Hello! Anyone can help with this, I need a report or just a certain number of CPU cores available on all hosts of ESXi connected to a specific vCenter, or in this case vCenters multiple and the output with the amount written to a file. No host name or other information, as the sum of all the cores available?

  Something like that?

• Permisions required for mounting NFS on ESXi host

  Hi team,

  In our java application uses) use API VMWARE to mount the NFS datastore on the ESXi host. But to do this, we need the ESXI root permissions. Because having credentials root door reached the safety of the system, we would like to create a user with the required permissions will be sufficient to add the mounting NFS on ESXi host.

  But do not know how to see the permissions required for the Assembly of the NFS on ESXi host. Pointers would be useful.

  Thanks in advance,

  Hello

  Storage permissions lies in the roles of Group of data store.

  You should have a default profile role of storage in your vCenter.

• Create the role in each ESXi host

  I need to create a 'Test' role with only 'Browse datastore' on each ESXi host in the vCenter server.

  OK, I see, you need a role on each server ESX (i). It is possible both with the cmdlet New-ferrule.

  Get-VMHost | %{

  $esx = Connect-VIServer-Server $_-user root - password $pswd

  New-ferrule-name Test-"Datastore.Browse" of privilege-Server $esx

  Disconnect-VIServer-Server $esx - confirm: $false

  }

  The script will connect to each ESX (i) server, create the role on the (i) ESX Server (with the server parameter) and disconnect.

  You will need to have the root password in the $pswd variable.

• How can I migrate an ESXi host since a vDS in a vSwitch with NAS storage on vDS

  I need to move some on a vDS esxi hosts to a standard vSwitch to move a new vCenter ESXi hosts

  I have two 10 GB network adapters that manage the ports VM, NAS storage and vmotion.

  Is there a documented procedure to move a vDS in a vSwitch, particularly for migration from NAS storage to a vSwitch?

  Thank you

  Tom

  No, you will need to do this on a per-host basis.

  I really recommend doing one by one, not in a hurry and checking all the networking before you proceed to the next step. Example: after migrating the vmkernel interfaces, check on a ssh connection to the host if it can vmkping the NAS. Before you move all the virtual machines on the host to the switch std, move one and check if the VM networking continues to function. This will prevent errors and downtime.

• How to change the sha - 1 certificate in my new esxi host

  Hi guys...

  as my lab crashed this morning (my computer has a blue screen) and of all the vm in my workstation crashed.

  When I'm the my computer upward run again and pressed 'play' to start the esxi host, I received some strange error messages.

  I decided to install a new host esxi5.1, and when I have finished configuring the esxi host, I noticed that the SHA - 1 certificate is not the same as the one I have (I have the new esxi I installed, and the older and sha-1 are different between the two hosts).

  I added the vCENTER esxi host, and now I have 2 hosts esxi 5.1 with different certificates of sha - 1?

  I can continue to work in this situation?

  I built this laboratory to study the vcp 5.0 certification. (I also installed the 5.1 vsphere to manage guests)

  It's a way to modify the certificate to the other esxi I have?

  Hope to hear from you soon,

  Best regards

  Hi Nahum,

  Each host is supposed to have a different SSL certificate

  If you are looking to implement of the CA signed CERT for only ESXi hosts, this should help

• Turn on ESXi host

  Hello world

  I was wondering, is there a way to power on a vCenter ESXi host?

  I have a test environment with a host connected to my vCenter, I disabled the ESXi host and tried to power of vCenter but is greyed out.

  I'm not 100% sure because I can't access my test environment for the moment. However I guess that option to power on a host is available with the Enterprise Plus edition (or in evaluation mode) when the DRS, and DPM (Distributed Power Management) are configured. What it basically does is trying to power on the host, using WOL (Wake on LAN)

• Dell VRTX + vCenter 5.5 + Shared storage is ESXi host import issue in vCenter. Help, please!

  All,

  I have two VRTX to be used for lab purposes that I am currently in configuration.

  Blades feature 4 VRTX with a shared storage infrastructure. Each blade has 5.5 installed on ESXi.

  I configured the shared on the VRTX storage, and all the blades can go very well.

  The question I'm currently facing is when you add the vCenter for managing ESXi hosts.

  Add the first host goes without a hitch. However, add any later host fail, because vCenter finds datastore attached hosts to have the same identifier.

  The error message is (see the attached screenshot): ' Datastore 'Main Shared-storage' is in conflict with a store of data that exists in the data center which has the same URL (ds: / / vmfs/volumes/xxxxx /), but is supported by different physical storage.

  Someone knows how to fix this?

  Thank you.

  Thanks for the reply.

  I think that I have found a workaround.

  First of all, this link does not address my particular issue.

  See, it's a whole new vCenter device installation and configuration. Only one of the four hosts to add host has been added.

  Still, the problem is that each ESXi host is a blade VRTX (M620), which has access to the data store created on the shared storage of VRTX.

  Basically, each host is editing the data store shared even (the only data store created on the shared storage), which works very well except for vCenter complain when you import the hosts.

  In any case, my resolution was as follows:

  -Add the first host with the attached and mounted data store

  -Remove the data store and detach the controller shared by other guests before adding in vCenter

  -Re-attach the controller shared and set up the data store via vCenter once guests have been added

  -Re-configure each host for vSphere HA if necessary

  Thank you.

• Mobile 5.1 ESXi host in vCenter unpublished 6 - license?

  Hi all -

  If I take an ESXi host 5.1, previously managed (under license) via a given vCenter (also v5.1) and its key in the inventory management, then I disconnect/remove this host from the vCenter 5.1 and connect it to a completely new vCenter, what happens to the host of license?

  It disappear and become a 60-day eval, or his license key moves WITH the host in the new vCenter?  (The new vCenter in this scenario would have absolutely zero license keys from host ESXi that apply to guests of ESXi 5.1 existing installs below)

  I was wondering what 'happens' in this scenario I have the document our so-called steps for migration.  Yes, I know that this could / should all be tested "in the lab" but don't get started me on that.  Thanks for any comments on what I can expect.

  My best guess is that the host will LOSE its license now, it becomes a 'standalone' ESXi host when disconnected and removed from the old vCenter (via the "Delete" command).  I want to just make sure that it is also fully functional, if she has run VMs on it at the time or not (although Yes, I'll put it in maintenance mode before removing the old VirtualCenter and join a new).

  And Yes, of course I have old games of the existing environment 5.1 ESXi license keys.  I'm just trying to set expectations as to what is happening in licenses-wise once I move the host from the old to the new vCenter.  I have all pretty well understood technical pieces, including AVS and DVS network considerations.  Thank you.

• 6 ESXi hosts can't be added to Vcenter 5.5 App

  6 ESXi hosts can't be added to Vcenter 5.5 App

  When I add the hosts drop off after 5 min or more.

  When you install or upgrade to ESXi hosts to 6.0 you cannot add them to vCenter Server Windows or device.

  It's real reason in the upgrade path, you must first upgrade the vCenter before ESXi hosts. See the sequence below:

  https://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=2057795

• ESXi hosts are disconnected from the vCenter (5.5)

  Hi all

  We have a little problem with our vCenter.

  We have two hosts that are connected to the vCenter, unfortunately, they are listed as disconnected.

  It seems that the problem are the SSL certificates on ESXi hosts that are no longer valid.

  If I replace the old certificates with new ones, that I have to restart the ESXi host, am I right?

  If so, that's the problem.

  We do not use any what automatic vMotion and as long as the hosts are not connected to the vCenter I can't manually, move right?

  Is it possible to connect hosts to vCenter without SSL?

  Sorry for my bad English, I'm not a native speaker.

  See you soon,.

  Johannes

  You need to replace the ESXi host SSL certificates.

  See the Docs for the replacement of ESXi Cert below.

  ttp://www.BlueBox-Web.com/2013/04/18/replace-ESXi-certificate/

  Documentation Centre of vSphere 5.5

  I had regenerate the ESXi 5.5 SSL certificates, which I did without any stop to virtual machines.

  Certificate replacement process can change based on the esxi version.

  According to the Doc, vSphere 6.0 Documentation Centre ESXi6 host must be rebooted to replace certificates.

  Anyway, in current state disconnected, you can try to regenerate the self signed SSL certs, restart management agents and try to reconnect host in vCenter.

  Thank you

• -= Decommissioning of a license key on ESXi host in order to import in vCenter Server Essentials 6 =-

  Our company recently bought a license for VMware vCenter Server 6 Essentials for vSphere (VCS6-ESSL-C) with license keys for VMware vSphere Essentials 6 for 1 processor (ha6-ESSL-C).

  I accumulated vCenter Server 6 on a physical device and assigned the new relevant license key, as well as installed Update Manager Server on this machine. This instance seems to be functional and functional.

  Now, I'm trying to import 3 x ESXi hosts in this environment which have the license keys from an environment "vSphere advanced 5. These 3 hosts are administered under an instance of VM of vSphere vCentre, that I want to the Commission under this license and the license on these hosts is no longer valid after a takeover of the company.

  Question:

  (A) Comment can I get correctly to the setting of these hosts so that I can use the new vSphere license key 6 that I received?

  (B) should I upgrade these hosts to v6 ESXi befin environment to use this new license key?

  (C) do I need to disable features on the hosts in order to apply to apply this license key "6 of vSphere Essentials?

  (D) what is the correct order for doing all these things to use this new environment vCentre?

  Thanks in advance for any assistance given.

  I havn't done it myself yet, but I think you should be able to achieve your goal, follow these steps:

  -downgrade license keys CPU Essentials to v5 im Portal MyVMware

  -the value of the new vCenter Server Evaluation Mode (actually maybe not necessary)

  -Add the licenses of Essentials v5 license vCenter inventory 6

  -Add hosts to the new vCenter Server ESXi 5.5 and assign licenses Essentials guests

  -re - assign the license previously removed to vCenter Server

• Create new vCenter and move the ESXi hosts

  Hello

  I created a new vCenter vCenter apparatus using ISO 6.

  The deployment went well and I have all the installation program. I would now like to move hosts our old vCenter to new ESXi.

  I was reading this article to start the moving process.

  When I try to disconnect the host I get the message below

  

  In the article in the link above it is written that it will not affect the State of the virtual machine running on the host.

  If I click on 'Yes' here, it will automatically put the host in maintenance mode?

  I prefer not to do it if I can avoid it because I don't want to have to evacuate all virtual machines running on the esxi host.

  Wouldn't it be better if I disabled it HA first? Then try to move hosts? Or I'm sure to sign-out and the subsequent removal?

  Thank you

  See you soon

  Hello

  You must put your server in maintenance as a first step mode, then unplug and remove the server. It will work.

  If it doesn't work, disable temporary HA and remove your host of the VC.

• How to change the config of vCenter Server Appliance (5.5) ESXi host vm? [Solved]

  I want to enable (set to true) memoryHotAddEnabled and cpuHotAddEnabled on the vCenter Server Appliance.

  I can't the powerCLI user because he needs a vCenter Server Appliance to connect to (right?) and to allow HotAdd of the virtual machine must be turned off.

  For anyone wondering, the best way to do this is to connect the ESXi host via vSphere Client, turn off the VM vCenter and update the configuration in this way.
