• Add Server ESXi in Vcenter 5.5 cluster with a different number of socket

  I have 5 nodes compute node IBM Flex System X 240 8737T7M with 2 CPU Socket in a VMS Cluster with identical hardware and now I need to add 1 more IBM System Flex X 240 node calculate 8737T7M with 1 CPU Socket in the same cluster.

  Here are other points: -.

  VCA Mode is disabled in this cluster.

  5 existing and new are the same model of CPU and memory is of the same capacity.

  Only the difference is 5 knots with 2 sockets and another node is 1. Please notice is recommended and he face any technical problem.

  VMware ESXi 5.0 and Vcenter is 5.5

  
  

  Hello

  VCA mode is not required when the generations of CPU on the server is the same.

  Adding your host in the cluster will work then.

  He advised not to add servers to a cluster with mixed material config. A possible problem might be the Admission HA control for example settings. If you configure a number of hosts reserved for failover, you may encounter problems with your hosts do not match each other. Here, you define the ability to failover in percentage.

• Can this load balance and HA cluster with vsphere?

  Hello community!

  Really new on this type of subject, so forgive me if IAM iam do or say something wrong. I'm here to try to understand better this amazing tool so I apreciate your time and knowlodge!
  Im trying to create a failover and balancing cluster with Vsphere, the goal is try to install an MSSQL DB server where the customer can access more quickly and do not have downtime when a node is down.

  I read a lot but still I can't have a full understand abt, so if anyone tries to explain something, please be patient and explain with precision.

  All doing wrong if you really work at home as a LABORATORY, and I can do it, hurt trying to use it to get a job because I don't have and I really need one soon!
  Here is my diagram is possible?

  

  Well ill to explain it, I have clients that will send a work for my DB load process, which will affect on MSSQL Server installed on the 12 TB logical drive created from the union of all methods virtual storage. Each virtual storage is just a virtual disk created on a virtual machine that is hosted on the physical server (node).

  So I have 4 physical server which have 1 VM each with 3 TB of virtual disk, the goal is the customer can send the process of workload on 4 nodes to have a quicker response, and if a single node fails for any reason, the other node can operate withow problem.

  physical server Medley: don't know yet if I have to use one or install VMWARE directly.

  Sagna VM: Windows Server 2008 (don't know if necessary or if I can just install SQL Server directly)

  MSSQL Server VM: 2008 Enterprise (still don't know if I have to use this one)

  Well I can't think right now on the other details, but if you tell me ill be happy to write it.

  Sorry if my writing or semantics is false but English is not my first language.

  Really thanks to get to this point and share your knowlodge!

  Best regards, josh of Argentina!

  Josh, please correct me if I'm wrong, you have 4 knots of MS - SQL, and you need to read/write at the same time in a shared database of 12 to.

  If this is the case check the following documents:

• Move the vCenter to another cluster... How?

  We rotate the camera 5.5.0 vcenter and need to move from a cluster with ESX 4.1.0 hosts in a cluster hosts ESXi 5.5.0.  Two clusters are in the same data center, but no space for common storage.

  We have migrated all the old cluster to the new VM using vMotion.  It is now time for the vCenter himself.

  How should I go about this?  Some downtime for vCenter is probably inevitable.

  Thank you... Lyle

  With the help of Support, here's what I did:

  -a clone of the vCenter VM for the cluster target & storage, but do not start the new virtual machine

  -change the properties for the new virtual machine so its MAC address is the same as the old VM

  -stop vCenter with its interface web admin

  -with vSphere client connected to the source host, stop the guest OS (suse) of the former VM

  -with customer vSpere connected to the destination host, turning on the new virtual machine

  Thanks to all for the comments... Lyle

• 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.

• Cluster with VSphere Essentials

  When I try to create a cluster with VSphere Essentials (no more) I'm offered HA and DRS (they are not greyed out, they are available). Are these trial versions that will be disabled in the future, or they are now included in Essentials?

  My understanding is that they would be unavailable at all. that is, they would be gray.

  To view your features under license:

  1. Open the vSphere Client and connect to your vCenter Server
  2. Select a host in your cluster
  3. Click the Configuration tab
  4. Click on the link "Features licensed" under the software

  All licensed features are presented here. Search for "VMware HA" and "VMware DRS" see if they are allowed.

  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.

• Change the Ip address of a cluster with Vsphere4

  Hi all

  I need help for work I have to do today.

  The problem is:

  -I need to change the ip on my local network addresses, the structure is entirely managed by Vsphere 4.

  -Now I have a HA cluster with 3 hosts, and I need to change the ip addresses of these servers Host1, 2 and 3 and the virtual Center host I ha ve a domain.

  Please, what is the best practice for this job can someone help me with this procedure?

  Thank you very much

  My steps are:

  (1) client connection vsphere in the center of the existing, disconnect all hosts and remove

  (2) stop vcenter services and change IP

  (3) start the vcenter services

  (4) change the address IP of ESXi console x 3

  (5) connection client vsphere with vcenter new ip address and add 3 hosts.

  make sure that any dns or hard-coded host name are modified.

• VCenter 4.1: cluster it?

  Hello

  Is it possible to Vcenter 4.1 cluster (2 nodes for example)?

  It was ok with VirtualCenter 2.5, under MSCS, but I don't see anything to do this for Vcenter 4.1...

  Thank you

  Concerning

  In our environment, our mandate is HA or not go.  Clustering is always a must... but for some odd reason, this does not applies to vcenter because it is a virtual machine that is running in a Cluster HA.  As for heart rate its good only to have a standby vcenter server and accessible. It is not mirrored DB, which can still be a single point of failure depending on your configuration.

  A few good insigts thereon:

• Creating a failover cluster Windows 2008 on ESX 3.5

  Hello

  I would like to create a cluster Windows 2008 on ESX 3.5.  As I understand it browse the forums supporting parallel SCSI as a type of shared bus was abandoned for Failover Clustering in Windows Server 2008.  To enable clustering, you need to use iSCSI on a target server.  Additional costs of license option for the introduction of a target server.

  Is ESX 3.5 update to support Windows 2008 failover clustering?  If so, when?

  Is there another solution that involves no additional cost?  I watched StarWind but the free version does not give us enough resources that is necessary.

  How ESX 4.0 supports Windows 2008 failover cluster?

  Thank you

  Brian

  In ESX 3.5, you can do a 2008 failover cluster with a software initiator in the node Windows 2008.

  For ESX 4 no problem.

• Initialize the cluster with data types different (lots of data)

  Hello

  I have data, which are composed of different data types. First of all, I have initialize cluster with these types of data and then "print" to light (photo). In case of photo data carries 8 characters than ja 4 floats. It was easy to initialize, but here's the question: How can I do this even if I have data that look like this (interpreter):

  floating point number

  name char [32]

  Short value [16]

  What I create loooong cluster which have a fleet of 32 characters, 16 short films? Or I can create these 'paintings' in a different way?

  THX once again

  -Aa-

  I suggest using the table-cluster and configuration of the cluster size to match the size of your berries, then package these groups together.  In terms of storage of LabVIEW, there is no difference between a group of

  floating point number

  Name1 tank

  name2 tank

  ...

  short value1

  short value2

  ...

  and a bunch of

  floating point number

  -> cluster shipped from

  Name1 tank

  name2 tank

  ...

  -> cluster shipped from

  short value1

  short value2

  So you can use the cluster table to get the right sizes rather than individually create all these values in a single giant cluster.

• Filling of cluster with references

  Hello

  I use "reference clusters" (def of strict type) and they make life much easier when you have a hand VI with a few controls and indicators and to change a property of one of these objects to a Subvi. Everything works fine when I have all the objects in a single VI and want to fill the cluster with "real" references, and valid.

  However, when I couple objects in several different screws and want to fill a single cluster with references, I get errors. What is the best way to get this?

  Attached two ZIP files: Method.zip first and second Method.zip

  Unzip the first Method.zip in a folder, and then open VI_1_First_Method.vi. Run the vi and keep your eyes on the white gauge. Everything works fine and VI_2_First_Method changes the background color of the white gauge.

  Unzip Method.zip second to another folder, and then open Populate_with_real_references_Second_Method.vi. Look at the block diagram. How to fill the Cluster_Second_Method.ctl with the "real" references objects VI_1_Second_Method.vi, VI_2_Second_Method.vi, and VI_3_Second_Method.vi?

  Thank you very much.

• Extend the current TMS Cluster with two new server

  Hello

  We currently have a cluster of two TMS-Server (13.2.1) installed on a W2K3 Server with a database on a SQL-Server separat

  To have a smooth migration, we thought the following procedure.

  Addition of two new server with W2K8 R2 by installing a TMS 13.2.1 to the cluster with access to the same database.

  After a while remove the two old server and upgrade to TMS14 (updated TMSPE in advance).

  Unfortunately, we get the message, as seen in the PNG-attachment during the installation of the first server in new.

  Anyone know if we could proceed as described above?

  Is the message because of the different operating system. If I click on 'Yes' former TMS-server still works?

  Thank you

  Concerning

  Ingo

  Hello

  The error message is misleading and can be safely ignored, and you can continue with the installation of the new TMS nodes. It was deleted in 14.0 TMS, see bug CSCui34702.
