Is it possible to add an ESX host less CPU

• Add production ESX hosts to a cluster

  Hi all

  I did some research in the admin guides and community forums, and I'm sure that I know what to do, but I would really appreciate a test of consistency here because the manipulation I do is in a production environment:

  I have a campus that contains two ESX areas that are managed by using vSphere and connected to a San. vMotion of works very well, the performance is very good (although the resources of the two boxes are fairly complete upward). However, I recently realized that I'd neglected to set up a cluster HA and DRS.  I want to remedy.

  I created the cluster with these specs:

  • the two HA and DRS, enabled
  • to the left, she also fully automated.
  • the power management of left
  • monitoring and host admission control enabled
  • leave the default settings for the behavior of the virtual machine
  • monitoring VM disabled
  • EVC enabled
  • the storage value of the swap with the virtual machine file

  I think that the next steps would be to add each ESX host consecutively and merged its resources with the cluster. However, here are a few questions:

  • How do you assess the risk factor to do this in a production environment (1 = perfectly safe, is a proven Scenario; 5 = you are out of your bloody mind? Do not)
  • Should I be triple-checking the SAN snapshots and planning of downtime for servers, or is it possible live and without any major qualms?
  • Am I right in assuming that it will increase my performance as well as provide better robustness of the campus, or should I expect a decrease in performance?

  Thank you very much in advance for your advice!

  Hey red,

  Addressing your particular situation, I would say yes to two questions.  Admission control HA is here to help you.  Ensure there are enough resources on the host computer to run the current and any expected load it will be after an HA event.  50% is close to default (but it is really based on the size of the slot) in an environment with two guests when guest cluster failures tolerates is set to 1 in a two and 25% host environment when the percentage of unused reserved as production capacity cluster resources in failover is left to its default value.

  If you have several virtual machines running that allows you to book 50% of your cluster resources (which it sounds like you have), then you have the option of "first category" your virtual machines and their giving priorities to restart event HA.  For their level, you'll want to active DRS (can be set to manual Automation), resource pools and you will need to configure your virtual machine under your HA settings options.  You'll want to pay attention to the priority of restarting VM here.

  I suggest you take a look at blog Duncan Epping http://www.yellow-bricks.com/ and Frank Denneman http://frankdenneman.nl/blog. They are all two fairly well the definitive answer to the HA and DRS questions and advice.

  See you soon,.

  Note: Epping and Denneman explained that the amount reserved by default resources when you use the host cluster failures tolerates is promising to reserve enough resources to power on virtual machines.  This reserve of resource does not on average current, account, or future default load.  If you want to manipulate this feature, modify the memory and CPU reserves, which are the numbers used to calculate the size of the slot.

• How to add an ESX host licensed to vCenter (vShpere4.1)

  Currently licensed for: 3 guests (Advanced vShpere 4)

  Ok.. so, I have vCenter upwards and in the course of execution, have created my 'cluster' with two hosts. I have an ESX host 3rd I was using mode "assessment" within 60 days.

  This 60-day period was close that expires so I moved and the 3rd license added to this 3rd host.

  I would now like to bring this host to vCenter, for my 'sandbox network' and not actually add it to the 'cluster' so that I can run everything a customer.

  Now, it is said that I am unable to bring this host to vCenter, as it says that I don't have a license.

  So, how can I go on the withdrawal of the license, or get this host (already licensed) in vCenter?

  Or do I have to start from scratch and reload this bare metal esx host to return to Mode Eval?

  Since it's vShpere, there is "No license server" by not telling.

  Licensing vCenter says that 'two' licenses during the third host is the 3rd license already.

  Any help appreciated.

  By the way... I have searched for hours on forums, web sites, etc., with no clear solution.

  Thank you

  Howard

  Interesting,.

  of your screen grabs, it definitel; appears as if you have only 2 licenses - as stated above, however, if your license covers only 6 processors, you could have used the additional licenses on them.

  It is really worth to check that, and if it is not the case, get your hands on VMware and ask why the additional licesnse does not appear in your portal.

• Add vcenter - I see all esx hosts too?

  Hello!

  I added our vcenter at VMAs, but when I do a 'vifp' mailing lists I see only the vcenter. Should I see all the ESX servers managed by the vcenter too or have to manually add all ESX host?

  You must add'em manually, or search for scipt to do.

• Disconnected ESX host cannot add to the CR

  It started with me being unable to power on a virtual machine that I created because of "Insufficient resources to meet the level of failover configured for HA" which is great because that's how to configure HA.  I tried to reconfigure the AP to the host by double-clicking on the host and select this option.  Once I did that it failed about 30% with "an error has occurred while setting up the HA Agent on the host" and the networking page disappeared from the configuration tab similar to what a lot of people reported during the upgrade, I think an earlier version.  This is not the case, I did not update anything.  Then I restarted service service mgmt-vmware restart and the ESX host disconnected from the VC altogether.  I can't use the VI client to connect to the host in question, but I am connected via the service console. All VM and the host not to requests ping and everything works. I've disabled HA and DRS and tried to add new ESX host that has not worked.

  Any help is appreciated.  Thank you.

  I found this article that has the same symptoms as you.

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=1004451

  Check if your esx.conf file is corrupted. Follow the directions in the KB article to restore or recreate.

• ESX host in several clusters

  Is it possible to assign an ESX host to multiple clusters?

  Thank you.

  None... An ESX host cannot be a member of the 1 cluster at a time.

• Two vCenters and mobile from one to another ESX host

  I have an existing vSphere environment where all virtual machines on the local drive. This environment is managed by a physical vCenter Server.

  I've built a WHOLE new environment with three hosts and each has 4 Sockets, 6 hearts with 128 GB of each host. I also created a new vCenter Server and it is a virtual machine. All are connected to the iSCSI SAN.

  I know that the ESX hosts can be managed by a vCenter server at a time. Now, I want to add old esx hosts that have virtual machines on a local drive to the new environment that is connected to a shared storage. When I try to add a host on the new vcenter server, I get a message saying that the host is already managed by the old server vcenter and if I add it to the news that it disconnects. Which is the best way to do it, or should I disconnect hosts from the old server vcenter first?

  Also how I will move the virtual machines on the local disk to the San. I have company over 4.1.

  Thank you!

  I unplug and remove the host from the old environment and then add the host in the new.  This will allow your guests to continue to operate.  Once you have hosts in the new environment, you can use sVMotion (right click to migrate, move the datastore) to move your guests to a shared storage.

• Cannot add the ESX 6.0 host to vCenter Server 6.0

  OK, I'm testing laboratory a vsan 6.0 cluster.

  I have my running 6.0.0 esx hosts and vcenter server is 6.0.0 also.

  I have the services platform on a virtual machine and vcenter on another. I was able to create a data center, then a cluster below.

  Then I went to try to add a host to my group and I get this error...

  Failed to contact the specified host (hostname\IP). The host may not be available on the network, may have a network configuration problem, or that the management on this host services may not respond.

  
  

  Per this KB: KB VMware: Add a host VMware ESXi/ESX from VMware vCenter Server fails

  
  

  I confirmed that my vcenter server and platform services server can see all esx hosts. From the vcenter server, it can ping the host esx and PuTTY can access all of them. I even installed the client and it can connect to all esx hosts. I used the netbios name, IP and FULL domain name and they all work.

  I have only a single subnet, so this isn't a problem. DNS resolution works in all areas of both sides, vcenter esx hosts and host esx to vcenter.

  
  

  I am quite puzzled.
  

  
  

  
  

  OK, after working with VMware on this issue, I think that I thought about it.

  All my hosts are DL360 G6 servers.

  My hosts are run the same build «VMware-ESXi-6.0.0-2494585-HP-600.9.2.38-Mar2015.iso» ESX Downloaded from HP.

  All buildings are in trial mode.

  After placing a call to VMware, they had me build some ESX VM, the services of the platform and the vcenter VM on an ESX host. We suspended because it took all day to go upward.

  Once I woke up all the parts (sql server, esx vm, server platform & vcenter) in virtualization nested, I created my data center, then Cluster then added the ESX host.

  The hosts added properly, no error. Then I remembered when I installed ESX inside a virtual machine, I am angry that the iso, I had the habit of HP does not work in my VM nested due to virtualized hardware.

  Then a fire came into my head. We will rebuild all of the physical cluster but NOT use the CV provided the iso file but use VMware provided iso file "VMware-VMvisor-Installer - 6.0.0 - 2159203.x86_64.iso".

  I did it today. I have rebuilt all hosts with the provided iso file VMware ESX...

  Spun SQL Server vCenter, service platform, all VM VM VM you need. My AD & DNS VM are on another server, so he has been upwards all the time.

  Connected to the web interface (yuck!).

  Created my data center...

  Created my Cluster...

  Add all my Cluster hosts.

  All of this worked!

  Therefore, if you encounter the same problem, I'm plan to generate your with the provided iso file VMware ESX hosts and try it. In my case, the provided HP iso file didn't work properly for me.

  I also downloaded the iso file of HP 2 other times to make sure and do a validation test and it did the same thing.

• Cannot add an NFS share on my ESX host.

  When I try to map an NFS share to my ESX host, I get the following error message:

  Any help would be appreciated.

  You have configured the Windows NFS share like that?

  

  With the esxcli command, below, I could mount the part mentioned above without any problems. Note that I put the root access bit allow under the Advanced NFS share permissions. Who can solve your problem if you have not activated it.

• 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.

• Add more disk space for the ESX host

  Hi all

  I need to throw more disk space to my ESX hosts.  I know how to bind records in Navisphere and present to the ESX host.  Once in the VI client, I "think" I need to go to the host and do a rescan of the HBA or something like that?  I'm a little unsure of the market of part VI to add more disk space.  Could someone just point me in the right direction?  Please note that I am looking to add more disks to existing hosts in existing clusters.  It adds no storage to a new host... rather an existing one.

  Thank you

  Jonathan

  You are on the right track.  Re-scan storage card, under the configuration tab select storage adapters, select the adapter and click on the link of the new analysis.  Then go to the storage section and there should be a link in the top right of the screen that says storage Add.  Click on that and it will guide you in adding/setting in form/naming of the new disk.

• How to add a new virtual machine to the ESX host using the existing files?

  I need to implement a function clone without the use of cloneVM_task. I copied (a special copy) a set existing VM Directory Active Directory to a new directory and renamed copied all files prefix name of the new direcotry.  What task VM (reconfigVM_task, createVM_task or registerVM_task) command can I use to add that the new copied VM on the ESX host? I need to manually update the .vmx for new UUID file and other parameters?

  Thanks for any help.

  I think that as long as you have updated all the names to reflect the new clone you must be fine and on the first step, you will be prompted with a question.

• How to add md1000 2.18 TB disk array to ESX host

  Hi, I am very new to VMware, and I try to add a picture of 2.18 TB md1000 disk to an ESX host.  When I go through the storage add wizzard, I see that he sees the md1000 2.18 TB of capacity, but shows only 1.8 GB available.  Anyone know what kind of configuration, I need to do for all the show of 2.18 TB as being available?

  Thanks a lot for your suggestions.

  John

  2 TB is the maximum for a single LUN.  You need to decreate your size of the LUN to less than 2 TB.

• Reboot the ESX host as possible while on VM snapshots exist?

  Can you safely do a reboot of a host ESX VM there was on this host which are off (of course), but have a snapshot exists at this time?

  Because we restart some ESX host but you also have to install some Windows updates on the virtual machine on these hosts. Normally, we take a snapshot of the WM, install updates, restart, check if everything is working fine, and then remove the snapshot. But after a reboot the ESX host we also check if the VM have started and are working very well. In this case, it would cost me 2 restart and check for WM

  When I could do the snapshots, installation of updates, power off the virtual machine, reboot the ESX host, turn on the virtual machine, all check and then delete the snapshots, it saves me time. Only thing I don't know and can't find is so it record to make a snapshot is by restarting the EX host and if the snapshot can be deleted after reboot normally.

  Welcome to the community,

  don't worry, a restart of the host is quite VMs, regardless of whether they are active or not snapshots.

• 6 zoning LUNs esx host

  Hello

  We have 6 esx host with 2 switches and 300 fc HBA each.2 Brocade on hus 110 with raid 5 7 + 1. !

  the scenario, I don't need a store of data for virtual machines or maybe another 2.

  in the storage Bay, I would add the LUNS in a port and then i will be the area each esx with this port, combining the fc switches 2?

  or should I make another raid group or LUN to the other port of storage?

  y at - it a pattern?

  You will need to create 4 areas by host, two on each FC switch, so a total of 24 areas for your 6 hosts with storage.

  Edit: has a quick and dirty "drawing." Take a look at the attached jpg. When you start storage, there are 4 possible ways to reach each server, which are your necessary areas.

  Concerning
