• VMs migration of a non - CVS to EVC cluster cluster

  Hi all

  I entered in an environment that has only one lit 9 hosts without EVC group:

  Host	Processor family	Processor	Version ESX (i)
  Host1	Penryn	Xeon E5450	4.0.0 update 2
  Host2	Penryn	Xeon E5450	4.0.0 update 2
  Host3	Penryn	Xeon E5450	4.0.0 update 2
  Host4	Nehalem	Xeon X 5550	4.0.0 update 2
  Host5	Nehalem	Xeon X 5550	4.0.0 update 2
  Host6	Nehalem	Xeon X 5560	5.0.0 Patch1
  Host7	Westmere	Xeon E5630	5.0.0: no patches
  Host8	Westmere	Xeon E5630	5.0.0: no patches
  Host9	Westmere	Xeon E5606	5.0.0 patch 6

  
  I'm looking to create two groups, one for the three hosts of processor Penryn (dev) and a separate for six guests Nehalem/Westmere (prod).

  If I put one of the hosts Nehalem in maintenance mode, remove the current cluster and place it in a new cluster with EVC lit with the CVO 'Nehalem' mode, I will then be able to vMotion VMs to two other guests the current to the new EVC cluster cluster Nehalem activated?

  I understand that the virtual machines on the hosts Westmere must be powered off before their migration to the new Nehalem EVC cluster but can I Motion VM hosts to the new Nehalem Penryn cluster virtual machines?

  Also the guests of Nehalem contain two types of processors: X 5550 and X 5560. This would impact on virtual computers fast vMotioning of a non - EVC cluster to a new cluster of Nehalem VCA?

  TIA

  Yes. You go from Nehalem, Nehalem, no problem.

  "I understand that the virtual machines on the hosts Westmere must be powered off before their migration to the new Nehalem EVC cluster but can I Motion VM hosts to the new Nehalem Penryn cluster virtual machines?

  Yes. As long as the instruction set is lower or equal to Nehalem, you can do.

  «As hosts of Nehalem contain two types of processors: X 5550 and X 5560.» This would impact on virtual computers fast vMotioning of a non - EVC cluster to a new cluster of Nehalem VCA? »

  As long as the non - evc cluster is Nehalem(or lesser), it shouldn't be a problem. Everything you do with CVS is hide which instruction sets may be available to virtual machines.

• VMotion between EVC cluster and native cluster

  Is vmotion between EVC cluster in Nehlem mode, and a standard cluster with Nehlem processors had problems?

  given that computers virtual are presented Nehlem CPU mode in clusters botyh as ok, it should work.

• Active EVC cluster will not allow guests to reach...

  Recently, I installed a new vCenter Server 5 (vCenter 4.x running on a 32 bit OS then upgrade was not an option-fresh install)

  I had 1 main cluster in the datacenter with HA and active CVS. All 10 guests were very well in it.

  However, when the new vCenter Server has been up - and after having removed the old vCenter data center, when I went to add the host to the cluster (same as before active EVC mode) 6 guests joined very well, while the other 4 could not.

  Everyone knows this? Just a reminder:

  new vCenter Server 5

  all 10 guests were in an EVC cluster well

  4 of 10 guests will not join the same cluster...

  Thoughts?

  Another question regarding VCA - if I point the old vCenter DB, the new vCenter server will this cause problems because a new database created for the new vCenter? How should I approach the issue?

  You can't do it now, you can not connect vCenter 5 dB in the version of vCenter 4, different schema, tables etc. as I said in my previuos reviews, you must migrate to vSphere with DB 5

  1. Start vCenter old (I hope that you did not remove or disconenct any server from there, right?)

  If you do not make any changes to the OLD vCenter vCenter should be able to connect to the return ESXi hosts and apply all the settings (including the CTS)

  And Yes, I take off (unplug the old vCenter servers... so I guess that reconnect the old Server vCenter is not possible.)

  If you simply disconnected the old vcenter ESX hosts (not deleted) you should be able to connect to vCenter old with old settings, but as I said earlier, I don't know what will happed with a VCA base (because you creted clusters with different CVS on new vCenter.)

• Changing the Mode of EVC Cluster for guests of Intel

  We cross a turnover of rental for our ESX host that puts out some old CPU architectures. Once we get rid of these hosts, we will be able to raise our EVC Cluster mode.

  (1) once ready, are there special precautions to take before changing the Mode of EVC Cluster? Then I just change the setting?
  (2) when the VMs will begin taking advantage of the new architecture CPU (a reboot will or VMs must they be turned off)?
  (3) any question with VM do not be put off for long periods of time after the VCA mode change?

  (4) all other things to worry about?

  If I raise the EVC mode, virtual machines will be able to access the new features available in this mode?

  Is that you turn off and then turn on the virtual machines. A reboot of the guest operating system is not enough. A virtual machine determines which functions are available to turn on and cannot access all the new features that are added until the power is turned off.

• EVC cluster creation / migration hosts him / minimal disruption VM

  I am reshape my somewhat environment and need a bit of advice.  Currently, I have 2 ESX hosts in a non - EVC cluster and built a new blade server.  The new blade and 2 hosts will work together in a cluster active CVS.  I know that I have to run my EVC cluster "Intel Xeon Core 2" mode.  All 3 hosts will support this mode.

  The News / 3rd cluster is sitting in his own vCenter, a VCA-activated cluster (in mode above).  Has no running VMS, it is already configured with network access and storage that matches that of the 2 existing/production hosts, which are currently managed by another instance of vCenter (but I am moving them out of this instance of vCenter in this new EVC-activated, to join the new blade.

  All hosts running ESX 3.5 U4.  vCenter is 2.5 U4.

  BIOS on guests must be modified to memory XD in so that they can be used in an EVC cluster, so I know I need to stop at SOME point to get them in the cluster active CVS.

  I have an idea on how to address these requirements, with a big goal is NO interruption of service for running virtual machines.  VMs can be migrated to a new cluster, EVC-activated, coming from an old cluster VCA not compatible?  Most all current VMs based on Intel some running already in reference "Intel Xeon Core 2" EVC mode or I'm just kidding me and must arrest all of them at some point after they "seized" a VCA-activated cluster?

  How would you do to this migration between vCenters and Clusters?  I think I can use 'Disconnect' the first vcenter (to at least avoid having to go into Maint Mode and then 'delete' of the first cluster/vCenter database)... also, I'm looking for the most logical get "here" to "there".  Thank you.

  I see that the problem of different vCenters/Clusters is resolved.

  What you need now is to know if you can VMotion between two ESXs with different processors. Before existing VCA, I have had... and had NOT a few difficulties doing this. It is not a problem when DIFFERENT pCPUs have the SAME GAMES of INSTRUCTIONS (SSE3, SSSE3, SSSE4 and so on...) Even if the sets are different, I was able to mix the MASK of CPU management options, which are by VM (thing that I didn't like... There should be an option to change this on a same CLUSTER basis or an ESX!).

  I recommend you to test for differences between the sets of instructions of the Jepp of two ESX with this tool, I think it is the best out there:

  http://www.run-virtual.com/?page_id=155

  If the sets of instructions are different, you have a problem, because you have to find the bits change in the MASK of CPU options in each virtual machine... and who needs a reboot, too. I think they will be different, because more recent pCPUs with FlexMigration (VCA compatible Intel processors), simply because they are new they surely have a new instruction set (perhaps SSSE4)

  Good luck!

• can we add L5420 and E5649 CPU model enable EVC cluster server

  Hello

  Cluster HA, we have 2 Guest ESXi 4.1 and model of processor are L5420 and E5649, and I am not able to Enable EVC mode.

  Please suggest how we can activate CVS my cluster

  Hello

  Theoretically, these two processors operate in the same cluster if you enable CVS for Intel host and select the profile "Penryn" Gen:

  

  In the case where you have not seen this, here are the compatibility matrix: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003212

  Does that help?

  Kind regards.

• Problem with moving of hosts with EVC cluster active

  I have 3 servers Intel cluster with EVC mode.

  I don't have a server in the cluster, and it is exactly the same as a single server in cluster (E7320 CPU)

  When I try to move this clustered server I get the error: the host CPU hardware does not support CVS on cluster?

  Thanks on help

  Have you already double check the BIOS settings. Intel-VT, Execute Disable Bit... This should be the same for all hosts.

  Are the hosts of the same provider? Same models =?

• vMotion no EVC EVC cluster

  Looking at the migration of our virtual servers that are currently on HP 25 p G1 (ESX 3.5 U5) processors of blades AMD 275 on too Hp BL460c G1 (ESX 4.0 U2) blades with processor E5320.

  The cluster BL460c aura EVC mode activated using xoen processor intel core 2. Live migration will be possible or will it had the VM being arrested and then migrated?

  Of course the same LUNS will be assigned to two clusters.

  If you need more info let me know.

  Thank you.

  You can VMotion of Intel to Intel

  You can VMotion from AMD in AMD

  You can migrate cold to AMD Intel / AMD to Intel.  The virtual machine must be turned off.

• Moving hosts between active EVC clusters (going from 4.1 to 5.5)

  Hi all

  This is my first post here on communities and I hope it will be a great moment

  Currently, we are running a cluster of production unique (4.1U3a vCenter) made 10 IBM x 3850 X 5 hosts where:

  • 5 guests have X 7560 Intel processors (ESXi 4.1U3)
  • 5 guests have CPUs of E7 - 8837 Intel (ESXi 4.1U3)

  Cluster is active EVC: Nehalem Genesis (Xeon Core i7)

  He must now leave whole cluster existing 4.1U3a vCenter for a new vCenter 5.5U1 constantly of the VMs system (we cannot touch/upgrading old vCenter). Is it not possible? Correct me if I'm wrong, but I want to do this way:

  1. Disable HA and DRS on 4.1U3a Cluster (let such VCA what)
  2. Disconnect the 4.1U3a Cluster hosts (a)
  3. Once that all hosts are disconnected remove hosts in the cluster 4.1U3a (one)
  4. Create new Cluster on 5.5U1 vCenter
  5. Select CVS on the new Cluster 5.5U1 vCenter (and set it to Nehalem Genesis (Xeon Core i7), as was the old 4.1U3a vCenter)
  6. Add a host 5.5U1 vCenter, off the new cluster (on the level of data center)
  7. Move newly added welcome the new active EVC Cluster to vCenter 5.5U1
  8. Repeat steps 6 and 7 for all remaining hosts
  9. Turn on HA and DRS on the new Cluster on 5.5U1 vCenter
  10. Test of vMotion and to each ESXi (and pray it works)

  This plan could work? I was testing this on the lab environment and all seems OK, but I'm afraid I missed something. As far as I understand CVS it should work as long as I'm not power cycle all VM during the hosts 'move '.

  Thank you all for your help.

  Normally you can not add directly to a cluster as when you import the host to vCenter he does not see as having enabled EVC and is safe.  I was wondering for the sake of ease, not want you back up the database from the old server and put this backup on the new and just update?  It may contain some old information, you may not, but that would mean that your hosts basically would come immediately upward in the cluster without having to do all that extra work.  Also do not go to the 5.5 Update 1 if you use NFS.

• EVC upgrade doesn't work not as expected

  
  So, I had my environment set to level to VShere 5.1 and improved my cluster of Merom VCA to Westmere the VCA above my two host systems are supported.  Then I started to reboot some of my less vital systems to put to level, but to my surprise, they all has not upgraded to Westmere.  Of the 7 systems that have restarted this day 1 has no upgrade at all and remained on Merom.  Two developed level to Nehalem and the rest went to Westmere.  Is it normal or I do not have something set up correctly?

  Power - off virtual machines, then in the settings of the virtual machine under Options - CPUID mask - advanced - reset default values. It must clear the existing settings from CPUID mask, and once power you the VMs on once again, they should apply the new EVC cluster mask.

• VSA on material different hosts in a cluster

  I installed VSA attemtped to VSA configuration for two hosts in a cluster with a different material and successfully. When I have case set up the ASB I couldn't add any of the hosts in the cluster. In the details, he says "guests shouldn't be in a cluster, hardware not supported." My question is...

  Should I remove the hosts in the cluster?

  VSA supports the hosts of different material?

  VSA can support my setup with a different configuration?

  I am new to VSA, so any help would be appreciated.

  Concerning

  Purpose of test, I missed more than one option you need to change in the dev.properties:

  EVC.config = false

  Turn off the host.audit allows you to select hosts even with unsupported hardware.

  This cannot be a permanent solution, because VSA configures an EVC cluster enabled as part of the workflow installation and vCenter Server does not add a host from a different family of the seller/CPU in a VCA active cluster.

• Migrate from vCenter to a cluster of a nonclustered Member

  Work on a new environment and I'm stuck with something sorta here. I have 3 guests, 2 are new material (r.620) and 1 is more old (1950). The 1950s was presented today, the R620s have been about 2 weeks now.

  Now that the 1950's the mix so I created a new EVC cluster limited to Penryn, r.620 1950 and one are in the cluster. I want the other r.620 in the cluster, BUT my vCenter is running on it. Cannot migrate the vCenter for memebers cluster because it is exposed to the extensions of the processor beyond the limit of Penryn from the pole...

  A little lost on what I can do here? Is there a 'stop invited, migrate to host X, boot prompt' type function I can use?

  Assuming you are using a shared storage accessible from all hosts, vCenter Server VM power off, remove it inventory of the current host by connecting it directly to the host (using the vSphere client), and then connect to the host of the 'target', add the server vCenter back to inventory and turn it on.

• Add esx cluster with different cpu

  Hi all

  I have a cluster with 5 esx 4.0 u1-208167, which installed on IBM x 3550 M2 ((2 x Intel® Xeon™ processeur E5520) .)

  I want to add a server to server cluster .the is IMB x 3550 m3 (2 x Intel® Xeon™ processor E5620 4 c)

  do I have to make a chenges on Esx servers / vm / vcenter when I add the new esx for my datacerter and to the cluster so I can do Vmotion / storage migrate this server in the cluater (I have the appropriate license and plug)?

  Thanks for the help

  is there another way to activate the CEV on my existing cluster and does not create a new?

  You can try to create a new cluster and select CVS it and move all your hosts to this cluster

  should I turn off my vm all?

  You will need to put the hosts in maintenance mode. So what you can do is put the host 1 in maintenance mode, virtual machines will move to host 2. Now move the new active EVC cluster host 1 and continue to do this until all of your hosts are in the cluster. You can try vMotion your VM 2 host to host 1 which is now in the new cluster, but it all depends on what your processor will hide VCA is activated... And if you cannot vMotion, virtual machine in a VCA not to an active evc cluster cluster, then Yes, you will have to turn off and restart your virtual machines in the new cluster

  I also have SRM ad site.do I need to activate the CEV on the cluster, I have here (a different Vcenter)

  No u don't.
