• Is it possible to migrate ESXi host between data centers, if so please provide a brief not

  Hi friends,

  1. is it possible to migrate ESXi host between data centers, if so please provide a brief walking distance.

  2 can we perform vMotion and Storage vMotion while ESXi is turned on.

  3. is it possible to extend the VMDK disk while it integrates snapshots in it.

  Best regards,

  Sirot Vijay

  Yes the vmotion and svmotion works but one by one.

  1 - vmotion is posssible to power on State, but you can't svmotion the vm simultaneously. The storage will remain same

  2 svmotion is also possible to power on the State, but you cannot vmotion virtual machine simultaneously. the host will remain the same.

  3 vmotion and svmotion is possible together when the vm is off power. the host and storage can be changed simultaneously on this State.

• Migrate ESX hosts to new SAN array

  Hello

  Our company has bought a new SAN storage array and we are looking for an overview on the migration of our ESX SAN infrastructure existing to the new array with minimal downtime. Currently, we use EMX DMX and will migrate to EMC Clariion.

  I thought that we could present the new table to the ESX host and then use SVMotion to move on the virtual machine, and then once we are full and everything is well, remove the old array. I don't know what the best solution practice to it would be...?

  Currently, we are on ESX 3.5 U2 in all areas.

  This sounds like a good idea? Any help is very appreciated!

  Thank you!

  -Mike

  It is exactly what you need to do.

  1. present LUNS of size equal to or greater than those on the existing table.

  2 format LUNS as VMFS data new warehouses.

  3 Svmotion VMs of new data warehouses.

  4. wait for a whille and ensure that everything is fine and then delete the old warehouses of data.

• Migrate the host ESX to vSphere 4.0 Server 4.1

  Hi all

  I have 2 vSphere environments. A server vSphere 4.0, and 3 ESX 4.0 host. Another with vSphere 4.1 server with 3 hosts ESXi 4.1. I want to migrate ESX 4.0 mailboxes to the new server for vSphere 4.1. Assuming that I have licenses installed locally on the boxes, and I squared away vSphere licensing, what would be the best way to migrate the host?

  I would simply ' right click-> delete ', then 'right click-> add a host' on the Server 4.1?

  Thanks in advance.

  the best way to do so is in vCenter 1, right-click and disconnect the host and then delete host.  In vCenter2, "add host".  This will move the hosts and their guests to the new instance without interruption.

• Storage vMotion issue License - license of moving between ESX Hosts 4.1?

  I have a question about Storage vMotion with ESX 4.1 license.

  One of my environments ESX 3.5 existing consists of 10 ESX 3.5 hosts - 8 ESX 3.5 servers Standard and 2 ESX 3.5 Enterprise servers.  I use a centralized license server (I think that's the correct term).

  I found that I can "move" the vMotion (and vMotion) Storage capacity of two of my 10 servers that only two of them are enabled for vMotion, both.  I do this by topic under VI Client-> select the host ESX-> Configuration-> network-> properties-> VMkernel-> Edit-> toggle the box "VMotion" activated-> OK.   I guess that by doing this, that I'm actually just spend my licenses 'ESX Enterprise' between the hosts.

  Be able to run Storage vMotion on one or two guests at a time is a lot for a few times a year I need to reconfigure my back-end storage.

  Two Questions:

  1. this use is technically legal in a perspective of VMware licenses?

  2. now, I'm looking to upgrade to ESX 4.1 and wonder if I'll be able to keep doing this?  I have read that ESX 4.x got rid of the centralized server license model, so not sure if I could 'move' licenses around like that... In fact since vMotion is now included in Standard Edition, I guess I could 'pull out' through a license only one ESX Enterprise server in order to obtain the license of storage vMotion.

  I let my support/subscription lapse for as long it is cheaper to purchase new licenses rather than paying for support costs with retroactive effect on my existing licenses.   The price difference between Standard and Enterprise is large (3 times the cost) that I don't think I can swing is business licenses for all of my guests past the bean counters, where the reason for this post.

  Reflections and comments?

  Each host has a license key number. You can apply a new license key to a host, and it is immediately activated. I guess you would be technically violate licensing for seconds as a license number was recorded at two hosts. There is a place in the vSphere client to "assign a new license key to this host. When a license key has been assigned, it remains as a choice, then you can simply choose the functionality licensed one and below the other.

• 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.

• HA can happen between a different version of ESX host

  I have two host ESX server, one is ESX 3.5 and the other is ESX 4, two of them are under the management of a VCenter server,

  I wonder if I can implement HA between the two ESX hosts

  Yes, this is supported.

• How to balance IO SAN controller between my ESX host?

  Hello good community.

  Question about SAN controller i/o balancing between my ESX hosts.

  I've identified the controller A and B controller on my SAN, HP EVA 6100.

  The controller has 50001FE1 500E1208

  Controller B 50001FE1 500E120C

  But when I go to "Storage adapters", then "Manage paths" by vmhba and I'm lost.  Policy of LB is fixed.    Then I see:

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 * status: active, preferred

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d

  If the first two on my controllers, don't know about the bottom two WWWN however, can someone who knows HP EVA help here.

  Also, I am very confused regarding mirrored ports and the need to be cautious when balancing the way between the controller.

  Which would be great if someone could give me a few white read books on it, the same and also fair knowledge base articles explain how to approach the above and examine the virtual machines as well.

  Not too big so... just small forum post I raised here... It will be useful someone help to get a dialogue going.

  What I do with my EVA, is having different LUNs (Datastores) manually selected a path preferred in command mode.  For example LUN 1,3,5,7 are on path then that lun 2,4,6,8 are set on Channel B.  This means that all your LUNS are also responsible.  On the ESX side each of my machines has 2 HBAs each with 2 paths that it looks like your Setup.  Here's what I think looks like load-balanced:

  ESX01-

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - LUN 1.2

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - LUN 3.4

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - MON 5, 6

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - MON 7, 8

  ESX02-

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - MON 5, 6

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - MON 7, 8

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - LUN 1.2

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - LUN 3.4

  It might not even be necessary have a configuration of blancing of load complicated if you produce not enough IO to saturate your current configuration.  You can just keep it like this:

  ESX01-

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - LUN 1.2

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - LUN 3.4

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - MON 5, 6

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - MON 7, 8

  ESX02-

  vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - LUN 1.2

  vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - LUN 3.4

  vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - MON 5, 6

  vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - MON 7, 8

• V2V between ESX hosts

  I just want to ask, I have to do cold V2V a VM on Wan via fibre-optic line and intend to use the 4 converter to resize the original hard during the process.

  ESX HAS | VM A (source) | VMFS on local disk-

  ---

  migrate - & gt; ESX B | (destination). VMFS on shared storage

  My question is, do I need an additional license for Converter 4 making the migration from different ESX hosts without vCenter?

  VMware newbie...

  No, you don't not need another license for Convertter as long as you use an instance of mono converter - also be warned converter on the WAN will take some time.

• How to restart vm esx host in different work HA?

  I understand that VMOTION = migration hot virtual machines on esx hosts. So, if HA uses VMOTION, how HA restarts VMs on another esx host when the original, we're out of service?

  I guess it will take to create an another vm on the available host using the same on the san .vmx file?

  IF we were to do it manually, it will be just import a virtual machine to another host on the right?

  Correct me if im wrong?

  A bit confused on the works of the HA behind the scene

  See you soon!

  VMotion and HA are not related or dependent on each other.

  (1) again, this works because the virtual machines themselves live on storage shared and not bound to a specific host ESX (i). ESX implements non-persistent locks on a specific virtual machine, when the host goes down, these locks will eventually timeout. HA will launch the failover, allowing it to reregister the VMs failed and restart. Manually, you can walk through this process by the presence of a virtual machine that lives on the shared storage that runs on HostA, then it turned off and cancel the registration of the virtual machine. You would be so I re-register on HostB and turn on, and voila, you've just simulated a ghettoHA.

  Here are a few extra links/documentation which may be useful for you better understand it:

  HA said:

  http://www.VMware.com/products/VI/VC/HA.html

  http://www.VMware.com/PDF/ha_datasheet.PDF

  vMotion explained:

  http://www.VMware.com/products/VI/VC/VMotion.html

  http://www.VMware.com/PDF/vmotion_datasheet.PDF

  (2) vMotion as you know already, performs a live migration of a virtual computer between two hosts, where as HA you will get some downtime of the virtual machine while it is rescued. The key is HA doesn't provide true high availability, it's just faster to recover. If you are looking for a true HA, take a look at VMware FT www.vmware.com/files/pdf/resources/ft_virtualization_wp.pdf

• ESX host is listed in DVSwitch, but not in DVportgroups

  Hello

  I have the following in a CLuster (5.5 Vcenter, ESXi hosts 5.1) problem:

  I added a new ESX to the cluster (number 9 of ESX), then added 4 network cards to the DVSwitch (uses the LACP Protocol).

  In this DVSwitch I 2 DVportGroups / tag VLAN

  The problem is the host is listed in the tab "Hosts" in VCenter to level DVSwicth, but do not appear in the DVportgroups tabs (all hosts are listed here but not the last one..)

  vmk0 migrated successfully to the VLAN 1 St... but now, it appears limited to ""... I can migrate to the DVportGroup right... and VCenter says 'ok'... but nothing changes...

  I tried to migrate a virtual machine on the ESX (2nd VLAN) = > VM pings OK...

  So "technically" it works very well... but the ESX does NOT appear as members of DVportGroup.

  The problem appeared when I tried to deploy a vApp (antivirus) on the ESX... I'm stuck at the "select VLANS for the NETWORK card"... There is no VIRTUAL LAN in the list... (because the ESX host is no not part of any dvportgroup..)

  I tried "adding the ESX to the DVportGroup" after having asked for credentials, VCenter says 'ESX is already part of the pole '...

  Someone had this strange behavior?

  What can I do?

  Help!

  Best regards

  S

  I had a similar case, where the hosts have been posted under DVS, but not under DVS exchanges.

  A restart of vCenter Service fixed the problem. However, I was not deploy any TIME or such.

• b/w esx hosts VMotion using CF Storage share.

  Hi, I wanted to know the esx communicate anything to the storage when its doing a vmotion. Lets say I make a vmotion between 2 esxi hosts share the same storage. I have a private just vnic to vmotion and a separate management and logging FT.  My vmkernel default gateway is the management of vnic. I do all the fiber channel for the shared storage.

  Once a vmotion over, the new esx host must tell the storage that the vm now lives on me. If storage is all CF, how do?

  Yes, locks are on the VMFS file system, so the connection of storage is used.

• ESX host for a virtual machine specific?

  An ESX (out of 3) host in a cluster has a physique more NIC

  We would like to place a special virtual machine on the ESX host.  Is it possible to attribute this VM to this particular host?  Needless to say, if there is a failure and that the VM is propelled upward on another ESX host, we will migrate it back manually.

  Your opinion is requested.

  Thank you

  With vSphere 4.1, you have host affinity.

  Otherwise, there's another thing, as to connect to a local iso file...

  But something can vMotion broken and/or HA.

• Migration ESX ESXi 4.1 4 what to do first?

  Hi all

  Suppose I want to migrate to ESXi 4.1 ESX 4.0u1 is it all things special to do or warnings?

  Now that I have 20 ESX hosts I would like to upgrade or migrate in ESXi 4.1, what is the best way to do it?

  Thank you

  Enterprise Plus is required for the host profiles. Another way might be to manually convert a host. Set up as you like, then export import using this backup vicfg from the link below or set up a basic configuration script you run, although I have not used it personally this tool.

  In the past I have also built a startup script as an alternative for ESX so deployments that could also be an alternative. I change the kickstart to each server and just point the installer to the queue of droite.ks.
