Change the ESXi host IP address

Hello

I have the following Setup for vSphere 4.1 and you must change the subnet:

1 - host 1.0.0.1

Host 2: 1.0.0.2

Home 3 - 1.0.0.3

vCenter - 1.0.0.99

I need to move all my guests and my vCenter to a new subnet:

1 - host 1.0.0.1

Host 2: 1.0.0.2

Home 3 - 1.0.0.3

vCenter - 1.0.0.99

I want to try a host first of so I moved all my virtual machines from the host 3.

I can go on the pages of Configuration/network host and select Properties on the virtual switch containing VMkernel port of my network management - from there it seems that I can just change the network IP management settings. However, it is the right way to do it? I thought that the best thing to do is the following:

1 disconnect the host vCenter

2. connecting to the host directly using vSphere client

3. change the IP address of the host management network

4 reconnect to the host (using the new IP address of the host) using vCenter

Should I switch to maintenance mode?

The same operation can be performed on a host running VMs?

Thank you

Change the management IP has no impact on the virtual machines running on this host. To make a change of this nature, I often disable HA (either completely, or uncheck "Enable Host Monitoring" on the segment of HA configuration). This will ensure that the interruption in the availability of management so that the changes of property intellectual fires any sort of isolation HA event.

HA, you should be able to make the change from the vSphere client attached to the host or vCenter. Just make sure that you have access to the consoles so you fubar the vSwitch and needed fix through tech support mode or the DCUI.

You are afraid to have virtual machines on the host, if not in maintenance mode to evacuate VMs. It is not necessary.

vCenter relies heavily on DNS, make sure that the new IP address reflects the input host DNS.

  • VM doesn't qutoboot upward after the restart of the ESXi host

    Hi all

    I environment, there is only a single Cluster. The Cluster has an ESXi host. all virtual machines including vCenter VM are resides on the ESXi host. When I reboot the host can all VM does not start?

    For comparison, there is a different environment, there are two Clusters (Cluster 1 and Cluster 2) in vCenter, Cluster 1 has two hosts ESXi Cluster 2 has only a single ESXi host. vCenter runs on the ESXi host residing in Cluster1.

    When I reboot the host residing in Cluster2, all virtual machines may start automatically.

    is that any expert can explain the difference? Why single environment can auto boot VMs when both of these environment has a host to the Cluster and cluster activate HA service?

    environments are executed at the ESX5.5.

    You will need to check the box allow VMS to start and stop automatically with the host system and then change the setting on the edit tab, and mention what needs to be done for each machine.

  • 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

    vcenter6_hostmove_001.png

    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.

  • Displaying output on the ESXi host?

    It may be a stupid question but just wanted to be sure. I have ESXi running a desktop PC with a cluster of virtual machines configured. The PC has a screen attached to VGA. This means that I see the ESXi etc host configuration screen.

    I can remote into the MV from my computer laptop etc, no problem, but I would like to be able to use the screen. So is it possible to show a virtual machine on this screen, rather than the ESXi host / console?

    The short answer is no, this is not possible.

  • Add the model mv directly from the ESXI host

    Hi gentlemen,

    I have a question:

    Is it possible to add a model from the ESXI host without using VCENTER?

    I browse to the data store and I select Add to the broom, but I get an error.

    Sort of to reach it without using VCENTER?

    The models are a unique feature of vcenter. You can try renaming the vm vmxt vmx file, this would allow to add the file as a virtual machine, not model.

    But anyway, you will not be able to use to deploy from model or the options you have for cela vcenter.

  • Change the view hosts ESXi and Vcenter Ip addresses

    Hello

    Because of our new zoning, we need to change the IP addresses of all our guests view ESXi as well as our vCenter server View.  Is it still possible without altering the DB ADAM that uses the view?

    Thank you

    Mooge

    If your ESX hosts are added to vCenter by host name and your vCenter are added to the view by hostname that you should be able to make this change without affecting the view.

    If your vCenter is added by IP, then you will have problems.

    If your ESX hosts are added by the intellectual property so that you can use maintenance mode to migrate all the virtual machines on each host, remove from the inventory, then add it to the cluster using the new IP or host name. View should have no problem with what we don't reference the hosts by their host names in any sort of statically.

  • 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!

    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.

  • Change the range of dhcp addresses for nat Vmnet8 for VMPlayer/Linux

    Hello.

    Vmplayer/fedora running. Trying to change the host address of range/ip dhcp for nat (vmnet8).

    Within the vmplayer gui, there is no apparent way to change the range/nat dhcp data.

    I see that there are a few vmware apps in/usr/bin pertaining to vmware, who seem to have an impact on the range/dhcp/nat address, but I can't find docs on exactly how it works. Also, where is the configuration for the dhcp protocol entry.

    Basically, I would put the dhcp/vmnet8 192.168.12.1 and present the range to be 192.168.12.128 - 192.168.12.135.

    Thank you
