Heavily laden prod cluster - manage a host failure?

• HA Question - why is there a limit of 4 host failure

  Hi guys,.

  Can anyone tell, why is there a maximum of 4 HA host failure while we configure up to 32 ESX server in the cluster?

  I don't understand, the concept behind this. It was even Vi3 & Vi4... Any ideas?

  See you soon

  In a VMware HA cluster, there are primary and secondary nodes. A maximum of five main nodes in a cluster is supported by VMware. If you lose the five cluster nodes or more, it is possible that you lose all of your primary nodes. This is why there is a limit of a maximum of four host HA chess in a cluster. See for more information Deepdive HA.

• Change of address IP of VirtualCenter, no host to ESX cluster management

  Hello all,.

  Our Team MS moved our VirtualCenter server to a new IP address. But since then, I had problems with a cluster I had previously put in place.

  Since the change, the cluster with 2 esx hosts cannot be destroyed, the esx hosts themselves cannot be dragged, maintenace ito disconnected or split mode.

  I suspect that it is because the hosts are always sending heartbeats to the old address IP of VCenter. Any action on the cluster or host of just hangs.

  Is that anyway, since the ESX servers themselves to be removed from the VCenter, so I can add?

  Trying to readd the host in VC me that it is managed under a server VCenter (old IP) and if you override you will be asked to get an error "the host is already connected to this server, VirtualCenter)

  Any ideas/thoughts will be appreciated.

  Have you tried to restart your Windows VC service?

• What is the safe and recommended way to simulate a HA cluster host failure?

  I would like to simulate one of our hosts ESX log to see how the cluster handles the load.  What is the way of VMware-recommended to do?  Pull network cable?

  Basically, I try to simulate something as a complete loss of power to one of the hosts.

  Disconnect the network service on your host console: this is the best way to treat your material.

• 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!

• How to manage the connection failure of network at the service of bussiness on OSB

  Hello everyone.
  
  Thank you for your attentions. I need help with the error handling in the OSB 11 g. I have a proxy that road to a business service to check the status of the service profile. I use the java client to use the proxy service and return the results to clients. The problem that I am facing manipulation is failure of the network connection.
  
  I want to get some message (or any useful information) of proxy service to indicate that the connection to the business service is not available when the connection fails. I tried to add the management of errors, but I can't found the action from the list of options.
  
  Can you review my proxy service and tell me some resolutions?
  Any suggestion is appreciated.
  
  I thank in advance

  You can add an error on the route action handler in your proxy service.

  you could investigate the $fault variable and check example what errorcode BEA... comes back.
  Then, you can decide what to answer in return... for example, create your own SOAP-fault and set your own messages.

  now the default $fault value generated by the OSB will be get back

• First license 10.5 Cluster Manager?

  Hello

  I install a new BE6K with version 10.5. I see the old ELM has been replaced by the License Manager first and, like its precessor, it is automatically installed with Callmanager and unity connection. I would like to install a standalone License Manager (version 9, x is possible) and here are my questions:

  1. is it possible to install a v10.5 first stand-alone License Manager on a BE6K?

  2. If so, is that I have a 'second first node License Manager' on a second unit of BE6K? The idea is to avoid having a single point of failure on this server

  Thanks in advance for your help

  DAni

  The BE6K is no different from the ordinary CUCM.  So, Yes, you can install PLM in independent mode.  But no, you can't have two.

  With Cisco Business Edition 6000, first LM would be usually living with one of the
  application servers. However, if you wish, it is possible to run first LM as a virtual standalone
  machine, but it should be counted against the maximum number of applications allowed on
  a Server Business Edition Cisco 6000.

  First LM is deployed as a non redundant application. Where the application of the first LM
  is no longer available (for example, if the first LM VM knows the operating system)
  questions and may not start), the customer has 60 days to restore the first LM application before
  application of the license occurs

• Cannot connect my vsphere client to manage my host... pls help!

  Thank you for reading... I'm new to esxi 5.1 and inherit a T110 Dell running a HD-250 GB for the OS (Esxi and Server 2008 r2) and 2-1 TB H.D for mirrow to SHARE DATA with the Microsoft software... (what a waste ah)

  everything was fine until about 2 weeks that I'm unable to connect to manage the server, it gives me the error:

  VSphere client could not connect to "IP address"

  A unknown connection error has occurred. (The client may not send a request to the server. (La connexion sous-jacente a été fermée: une erreur inattendue s'est produite sur un envoi.))

  If I point the browser to the IP Address of the host as: https://hostip (the page cannot be display)

  -Windows server is running

  -i can ping the Esxi

  Problem is that I have to update the memory and I'm afraid that after I have does not connect... and then I'm in big trouble... because I hand turned on inside the Esxi server.

  I did not backup, but the person in front of me was not do backups with veeam... instead they used a regular backup of windows on a USB software... I tried to create a re-usable collection and of course does not work... He was asking for a driver... I think it was for the hard drive... I free veeam now... but I can't connect it either... the box of Esxi.

  I would be grateful for any suggestion... Thanks in advance.

  You have access to the T110 Dell physical console?  Can you sign here?  If so, you could restart management agents:

  You can also enable the shell that allows you to try all kinds of connectivity tests:

• install vCSA single host and manage this host of "inside".

  Hello

  This is probably a stupid question, but I have found no reference or information about it:

  is it possible to install vCSA on a single host, which will be then handled by the same vCSA?

  background: there is only a single physical server available.

  are there disadvantages with such a configuration, and if there is, which could be problematic? same starting the server cannot, because it does not find the vCSA server to validate its license?

  I know that an update manager will not be usable, as the upgrade of the host, all virtual machines must be turned off and the host is in maintenance mode. This isn't a problem, as a manual upgrade of a single server is really easy.

  Best regards

  Mayr Oskar

  I agree with Gortee about the DVS, because that would be a factor limiting.  Since it is a single host it is useless to DVS anyway (unless you need the ability to scrutinize traffic in native mode).  I use the full vCenters blown on my main data centers, but I have a bunch runs exactly as you mentioned (about 60 sites with single host + VCSA + vStandard Switch).  No problems.  Good thing is that you can define the order of auto start since you do not HA.

• Change the host for a virtual machine on a cluster and the host is not in accordance with the attached profile

  Hi all

  I have 02 questions.

  1. we have a cluster which has 02 physical hosts (Host1 and Host2). We have 02 virtual machines on the Cluster. Active DRS on the cluster.

  But the problem is that my 02 VMS are always stays on a Host2. A few weeks ago, each virtual machine carried out on each host. How can I place each virtual machine on each host to perform better.

  How to do this?

  2. I connect to the cluster using vSphere client 5.1, under summer host, I get the following message

  "Configuration problems: host is not in accordance with the attached profile.

  I suspect that this is the case for my question 1?

  Thank you very much

  Hello

  I think I found the answer for the problem of home profile. I changed the following values to 1 for each host to > settings > under software > advanced settings >

  Under Data Mover

• State of the virtual machine after the host failure

  Hello

  If a virtual machine is running on a host and that host suddenly powers off dirty, like a power failure or a remote access card power the server due to a fault, overtemp etc., what happens to the virtual machine?

  My guess is the virtual machine is actually difficult, dirty off too and if HA is configured, etc it is going to do a full power on sequence. Or is it restart on a new server and be automatically in the same power state with the same States of memory and cpu until the host has dropped dead? So if I got a connection of the DRC in a vm of windows server and the host dies suddenly and it restarts, reconnect to the session even State immediately before the breaking of the host?

  Thank you

  When ESX\ESXi fails due to power failure:

  No configured HA:

  1. all virtual machines is also faces off against the sudden stop. SMV will lose data runtime and all communications (including the RDP connection) will be interrupted.

  Configured HA:

  1 VMs will be powered - on on a different host. However, its the same as a reset of the virtual machine, we will lose any unsaved data.

  VMware FT:

  We ensure 100% uptime for a virtual machine using VMware Fault Tolerance. In case of failure of the host, next time school resumes VM in FT. More details on IP are available at the following link.

• Cluster with different host - resource pools hardware?

  Hello

  We have currently three generations of servers at base of AMD in our environment - with different CPU clock speeds.

  Guests are split into three groups and VMs are grouped based on clock speed.

  But frankly, it's a mess to administer.

  We envisage the creation of a single cluster and using pools of resources.

  But CPU resource pools take host speed of the CPU in return?

  - Or they just sure that VMs receive their share of CPU temps on loan-time partial?

  Best regards

  Martin

  Pools of resources sharing works only when there is some conflict of resources.

  -VMs in 'high' will appear on hosts with fast processors? - and get the most MHz?

  The actions are only priority... Then no.

  With a reservation... it depends on how much MHz offers...

  - Or they simply receive a high share of CPU time on a random host?

  By shars Yes...

  But remember the first sentence!

  If you have enough of free resources, all virtual machines are also (for actions).
