• 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.

• 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.)

• Query regarding VCA and clustered environment

  Hi all, we are currently a slight dilemma and need some advice/help with the installation of clustered environments in VC 4.1.

  Here's our installation composed of 2-pole in a data center:

  Cluster_01

  VCA Mode on Intel 45nm Core 2 Xeon

  2 x servers Dell PowerEdge M600 blade installed with ESX 3.5 (failure of waiting to rebuild with esxi 4.1)

  4 Dell PowerEdge M600 blade servers with ESXi 4.1 x
  E5450 CPU Chipset
  Enough clustered resources to satisfy a host failure.

  Cluster_02

  People with disabilities VCA

  2 x Blade Server PowerEdge of Dell M610 installed with ESX 4.0 (failure of waiting to rebuild with esxi 4.1)
  E5540 CPU Chipset
  Resources on the host for the loss of a node in the cluster.

  * We combine the hosts in a single cluster and enjoy the VCA mode the question?
  * It would be any degradation of performance of guests running?
  * If the newest blades are added to this group in the future what exam must we do? Once again, if CPU

  features are hidden to make it compatible with the cluster that would frustrate the purpose of again model

  Blade and features of the CPU?
  * If we consolidate the clusters we simply turn off guests, remove hosts in the cluster and add the cluster 1 then restarts?

  * Don't disable us the VCA mode in Group 1 and keep configuration cluster 2?

  Your help is greatly appreciated.

  Because the virtual machine are running on a recent processor without activating EVC, you can't allow him to 'downgrade' function CPU.

  You must stop the virtual machine, put the host in maintenance mode and migration in the EVC cluster.

• Clearance of EVC nondisruptive?

  Hi all

  I need to activate CVS on one of my groups. Even if it is very simple to do, I want to do this preferably without turn off all the virtual machines. I've read a few articles where people supposed to have done by creating new temporary clusters, move the machines virtual etc...

  Also their articles claim they could live migrate a non - EVC cluster VM enabled an EVC cluster enabled as part of the process. I don't think it's possible!

  Can someone give me advice on the possibility of this being possible?

  I run Virtual Center 2.5 update 4 and ESX 3.5 Update 3.

  See you soon

  Mike.

  As long as you use a host of the original cluster to create the new EVC cluster, you should be fine.

  the procedure below, I used (just in case, but you probably know that)

  • Put the host in maintenance mode

  • remove the original cluster hosts

  • create new active EVC cluster

  • Add a host him (check the NX/XD and Intel_VT options in the system BIOS. These options must be enabled)

  • VMotion files from the old to the new cluster.

  • disarm the former cluster

• EVC right for our installation?

  I'm looking for some advice if my thoughts on the next steps with VMware are good...  Please bear with me that I may not be spot on if terminology advanced apologies for that!

  We currently have an infrastructure of vm on 10 machines, all the specifications of Dell are:

  2 x PE2950 (51xx Series)

  4 x PE2950 (53xx series)

  4 x M610 (55xx Series)

  All a bit of a mixed bag when it comes to VM versions and I have took it upon myself to get them all to 3.5u5 before look us again at 4.x.  While I did I was wondering about the question to know if we use that it is better.  With the kit above, they are divided into 2 groups with the M610 in a cluster themselves and the rest being the original cluster.

  Now, knowing that I don't potentially get replacements for the 2 original anytime PE2950 soon I think to keep them in the loop and we give the best with regard to the performance/failover protection, implementation of a new cluster with active CVS and gradually migrate all hosts, including the new knives through to the active EVC cluster.  I know from what I've read so far I'm going to lose a part of the new feature in processors on the blades, but would this loss that be bad?  Finally, the idea is (funding allowing!) to replace all the 2950 with blades and again from my understanding when that happens I can raise hardware on CVS across the entire cluster.

  Thanks a lot for any advice you can provide.

  Before CVS, you can create your own CPUID masks, which hide the features in the processor.  In general, SSE2 and some other features may be hidden without any problem. Then SSE3/4 came out, and masking these features on was not officially supported.  When intel/amd came out with the ability of their processors to match the VCA mode in ESX, then these new features may be hidden so safely, which is essentially what CVS does for you.  It will bring all the CPUID processor to a reference point automatically.  I've never seen these features used on a server, only on desktop computers.  If you do not use your servers as workstations, I can't imagine you ever notice, much less to miss these features.

  A possible cause of annoyance, are applications that do not use CPUID for characteristic unelistede of the processor.  In other words, if the application knows that she wants to use the feature X and uses characteristic X, although when the app 'demand' the processor of these characteristics, it is said that he does not have. Most applications will pull CPUID and to use the features on this basis, except in some cases when it is not used.  This is probably what you have heard of.

• Can I return to a previously created snapshot after activating the CVS?

  I will be performing a sizable maintenance SAN operation this weekend.

  Before closing down our VM, I'll take a snapshot of a couple of machines to simplify retrieval occurs enforcement issues (we had questions to set up the first domain controller in the past).  I would, since what it is very rare to have all our guests, power off, turn on CVS at the same time.  However, I fear that a snapshot taken before EVC is enabled can be invalidated by the Act of activating EVC (vmx files are included in the snapshot, correct?).

  I will be able to return to this snapshot when EVC is enabled?

  If by default, I can't, can I manually update the vmx file to activate CVS until the entire cluster is enabled?

  ESX 3.5 Update 4

  VirtualCenter 2.5.0 (Build 147633)

  Hello

  Moved to the ESX 3.5 forum.

  I will be able to return to this snapshot when EVC is enabled?

  VCA is the vCPU and indicators defined at initialization of the virtual machine.

  If by default, I can't, can I manually update the vmx file to activate CVS until the entire cluster is enabled?

  VMX not updated when you enable CVS, what happens at a higher level, it is not a virtual computer.

  If it were me, I would commit snapshots BEFORE upgrading your San for VCA just to be safe. But I don't think that you will have problems. It would be something that I tested until I turned off the system.

• Virtual ESXi / nested virtualization and VCA

  Hi all

  We tried to install some new virtual ESXi servers in our dev environment. to help our R & D.

  The problem is that our clusters must be activated EVC - Merom Genesis so that R & D for work stuff.

  I tried to use the following two articles:

  http://www.virtuallyghetto.com/2011/07/how-to-enable-support-for-nested-64bit.html

  http://www.virtuallyghetto.com/2012/02/how-to-configure-nested-ESXi-5-to.html

  After finishing the first link, the ESXi virtual is able to run 64-bit virtual machines. So all is well (although I stumbled upon both problems with this - apparently, you can't physical host the virtual ESX running in a CVS in the first place of accommodation).

  So after the ESXi virtual is able to run machines virtual 64-bit, I continue to the 2nd link and it doesn't work. I do exactly what the guy said there is still the virtual ESXi is not compatible with the EVC cluster and the 64 bit hosted on the virtual ESXi VM cannot run after changes to the CPUID mask.

  Someone knows something similar? Someone has ideas of what I'm doing wrong or can give me some ideas on what to do?

  Thanks in advance,

  Nitzan.

  In my view, the following option:

  CPUID.1.ECX = 00000000000000001010001000011001

  should be

  CPUID.1.ECX = 00000000000000001010001000111001

• Host CPU is incompatible. ? !

  Ok

  I did a lot of research this upward and have found ways to correct this and comments, the problem is that I have three DL580 G5s that are entirely similar,.

  Same memory, CPU, even network cards, same level of BIOS.

  But when I try to migrate a guest to the second of the three I get a title and a discrepancy detected above these features: * NX/DX and so on.

  I have two clusters (first is DL380 G5s x 6 is second of the G5s DL580 x 3), I don't have this problem with the first group, can I VMotion a guest in the first group at will (in the first cluster only), I just tried to VMotion a guest from the first to the second cluster (power off) without problem.

  Now what I find is the guest of the first cluster can be moved to ONE of the hosts of the second cluster No. errors!

  Anyone have any ideas of what I'm againest?

  Thank you!!

• Problems with dvSwitch cluster with leaves HP G6 and G7

  Hi all

  We have an active EVC cluster (vCenter 4.1 /. ESXi4.1) with 490c G6 HP blades. Now, we want to add new 490c G7 HP blades.

  It works without problem in clusters without dvSwitches. In clusters with a dvSwitch, as soon as we add the new host of the dvSwitch, or do any other operation dvSwitch, the new blade Gets a GROUP:

  "#PF exception in the world 4129:helper11 - 0 IP addr 0x417f8011000 0x41802656686c 14.

  If you start the server it CMTF again. If you remove the pole one ESX departure once again, it works, until you try to do an operation on the side the dvSwitch ESX. You will need to do a fresh install on this blade for the ESX Server.

  Everyone makes the same expirience?

• Issue of INS-35354 when installing Oracle RAC 12 on infrastructure Oracle Grid 12

  Hello

  I am trying to install Oracle RAC 12.1.0.2 one node installation on Windows Server R2 2012, but the installer told me:

  'Valid [INS-35354] the system on which you try to install Oracle RAC One doesn't not part of a cluster.'

  On the same server I have is installed and running Oracle Grid Infrastructure + ASM.

  I don't know what is missing the installation program, which is possible to register? The installation program does not provide which had not passed the specific audit.

  Thanks for the tips

  Georg

  

  

  

  Hello

  A CCR node does not mean that you install the grid infrastructure in a single node and install a base of a RAC data on this node.

  Basically, a concept CAR is similar to active passive clustering to provide high availability. To have a node database RAC upward and launched, you will have to install clusterware on at least two server by selecting the option during the installation of the IM.

  Pls follow the below post for detailed answer

• vMotion works between HP DL380 G7 and the Gen9

  Hi all

  VMotion I would like to know how working with HP DL380 G7 HP DL380 Gen9?

  Can someone help me?

  vMotion between this two servers:

  HP DL380 G7:

  Intel Xeon E5649

  Embedded NIC 4x1GbE

  + NC364T PCI Express Gigabit QuadPort

  HP DL380 Gen9:

  Intel Xeon E5-2650v3

  Embedded NIC 4x1GbE

  + 10 GB 2-port 10GBASE-T 533FLR-t HP FlexFabric

  Can someone help me?

  I would be very grateful
  

  Ralf
  

  The G7 has a CPU of generation Westmere, the Gen9 has a generation of Haswell CPU.

  vMotion requires that you have the same subset of games of CPU instructions and common on the source and destination of the CPU and active features in the server BIOS.

  This means that in your case:

  You will be able to vMotion virtual machine that has been powered on the host of the G7 (VM runs with Westmere instructions) for the Gen9 and so (but only if you don't re - power cycled the VM on the host G9).

  But you will not be able to vMotion virtual machine that has been powered - we on the Gen9 host (VM runs with Haswell instructions) to the host of the G7 most old car is missing these more recent CPU instruction sets.

  VCA comes here. By activating EVC on the common cluster with the generation of CPU down (in your case Westmere), all guests will present only these instruction sets to virtual machines when they are powered - on, which makes possible dynamic migration through the different physical CPU generations.

  See the following articles for more information about CVS:

  VMware KB: Enhanced vMotion compatibility (EVC) support processor

  VMware KB: EVC and CPU compatibility FAQ

  Alternatively you could manually hide CPU instructions by VM - with advanced options if you don't have a source host and destination in the same cluster, but it is a tedious task and I would not recommend it.

• Regarding vSphere VCA and vMotion

  Hi all

  I have several questions about vMotion and VCA, can anyone help?

  1. If I mix several types of CPU (from the same supplier of CPUS) in a vSphere without EVC cluster active, what will happen? can I vMotion VM on the host?

  2. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not activated on the two groups.

  3. can I vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not enabled on the source cluster, but active on the destination Cluster.

  4. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Suppose that EVC is enabled on the source cluster, but not active on the destination Cluster.

  5 can I vMotion of virtual machine of a stand-alone ESXi host on an active EVC cluster? Assume that the CPU is the same.

  6 the KB "EVC and CPU compatibility FAQ" below, if we disable CVS on a cluster, the virtual machine can only be migrated to hosts with CPU even or more.

  Why virtual machines is only able to move to other ESX/ESXi hosts that are in the same generation of CPU or more? It's in front of my knowledge.

  VMware KB: EVC and CPU compatibility FAQ

  What is the impact on vSphere features of the Cluster when I turn off the CVS mode?

  To turn off the CVS on a cluster mode, it affects vSphere Cluster features in the following ways:

  • vSphere HA (High availability): vSphere HA is not affected because of the cyclic power failover virtual machines when you start on a new host. This allows the VM picking up the new ID CPU and it allows to start without problem
  • vSphere DRS (Distributed Resource Scheduler):
    • vMotion: virtual machines is only able to move to other ESX/ESXi hosts that are in the same generation of CPU or more. If the DRS is configured for fully automated, this can result in virtual machines, eventually migrating to hosts on the cluster with the generation of CPU more old where they cannot be moved via vMotion on different hosts with a newer processor generation.
    • Storage vMotion: virtual machines are able to be moved to Storage vMotion with EVC mode disabled in a cluster
  • Location of the pagefile: it is not affected.

  Thank you.

  1. If I mix several types of CPU (from the same supplier of CPUS) in a vSphere without EVC cluster active, what will happen? can I vMotion VM on the host?

  (a) you very well can vMotion virtual computers between the hosts with identical processors within the cluster.

  (b) for vMotions on different hosts, it depends on CPU instruction set parity and orientation, i.e. the older generation-> new generation or vice versa.

  Consider the following: when a VM is turned on at the start, it is presented in UC sets from the physical host, where it has been turned on. It must keep these settings until the virtual machine is turned off, any host it is migrated to in the meantime. Therefore, as long as a host provides these CPU instruction sets, it can be vMotioned it. Further instructions on new hosts games is irrelevant for this and just hidden-away of the guest. So old-> new should be fine, but new-> old most likely will not work because the virtual machine works with games of additional CPU instructions that only is simply not supported by the older physical processor.

  2. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not activated on the two groups.

  Yes, generally vMotion shall function in older generations of CPU to the most recent, the same common CPU instruction sets are supported by the destination CPU host and enabled in the BIOS.

  3. can I vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not enabled on the source cluster, but active on the destination Cluster.

  4. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Suppose that EVC is enabled on the source cluster, but not active on the destination Cluster.

  Yes, the same general vMotion as explained above requirements. If CVS is enabled on any, both or a cluster does not matter (of course provided a configured VCA level is not reverse the physical hardware capabilities 'new' and 'old').

  5 can I vMotion of virtual machine of a stand-alone ESXi host on an active EVC cluster? Assume that the CPU is the same.

  Yes, the same general vMotion as explained above requirements. A stand-alone host is exactly the same thing treated as a non - active EVC cluster.
