• Data on the server failure recovery

  Hi all
  
  The rule of thumb: each 1 GB JVM can store 350 MB of data of the real object, assumes that we have 8 GB of data on the consistency, according to the above rule:
  
  8192/350 = ~ 24 JMVs required = > 24 * 1.2 = 29 ~ GB
  
  Then we have at least 2 servers of 16G RAM.
  
  We plan to have 4 virtual machines Java as cache servers on each of the two servers 16 GB as it advocates cannot have more than 4 GB of heap for each node in the cluster.
  I wonder if one of the servers fails, nodes in 4 cluster residing on it go down. If primary and backup of certain data are distributed both within these 4 cluster nodes that descend, then the data is lost even the other server has sufficient capacity for full redundancy.
  
  Is this correct? If so, how to solve? Is smart enough to put main and in the various boxes, not just different node each time as possible consistency?

  Hi Henry,.

  Not consistency inherently tries to minimize the risk of data loss and automatically checks the backup copy of the data to be kept on a different machine when possible. There is no more adjustment required for it. The StatusHA is the status published by JMX metric of coherence and more details can be found here:

• vCenter Server Recovery of Cluster has failed (Site A to Site B)

  Hello community VMWare,

  I was wondering if someone could help understand me the following scenario.

  I have two Sites, and each one has its own VMWare Cluster.

  Site A Cluster goes down, which hosts our vCenter Server.

  The vCenter Server contains all of its components, for example database.

  I want restore vCenter Site b, so as the SAN and the networks are online I could just connect to an ESXi host, browse the data store, import the vCenter Server and turn it on?

  The only thing I could think of who could stop me is a possible file lock.

  All guests will perform in ESXi 5.5.

  I tried searching google but couldn't really find this type of scenario.

  May I use the wrong search words so my apologies to advanced if I missed something obvious.

  Thank you.

  Power on this virtual machine to the other site won't be a problem.

  Since you will be reproducing original VM of the Site A to Site B, they're just files residing on the data store, no locks on them.

  But of the things to think about is, network setting the guest OS etc. If you use a different subnet to the recovery of the site (Site B in your case).

• VMware Data Recovery 2 in a vCenter Server

  Hi all

  I need a base backup of VMS backup solution. I know that each camera VDR is bounded to vCenter server, you might not use vcenter several with one camera VDR. But in a sense the opposite? I use several VDR devices with a vCenter server? I know about the limits of the VDR and probably I can achieve limit of 2 TB and only solution in this case use another camera VDR, but I don't know if it is possible to use more than a VDR with a vCenter.

  You can use up to 10 of VDR with a VirtualCenter.

  Look at the "VMware Data Recovery Administration Guide" on page 16:

  Special data recovery Compatibility Considerations:

  Ten aircraft recovery backup of data for each instance of vCenter server.

• Restore backups of data to different vcenter server recovery

  Hello

  We have separated closed vCenter in our society in different places, I'm just starting to use Vmware Data Recovery instead of VCB for backups. Is it possible to restore the backup of Vmware Data Recovery of Virtual Machines to a different vCenter Server?

  If you can, you could point me to documentation that shows how?

  Thank you

  Glenn

  You can create another device VDR with the same data from disk (or NAS share).

  Then connect to this device (you can also use the VDR plugin when you are connected to a host, not only when you are connected to vCenter) and wait until it import the backup catalog.

• vCenter server recovery?

  I have a few questions about recovering from a potential loss of the vCenter server and/or database.

  1. the vCenter Server and the database server is two separate physical/virtual desktops and the vCenter server is for some reason destroyed. It works simply by creating a new ODBC connection on a new server and then reinstall vCenter here?

  Not to mention the client vsphere score on the new server, it would be all that needs to be corrected?

  2. same scenario, but the database server is lost, but survived the vCenter. Assuming that you have backups of the database, but had to put it on a new server with a new computer name and IP address. What needs to be done to the vCenter Server? Is it possible to create a new database connection to the new server without having to reinstall vCenter?

  1. it would not work. I did it before using the following procedure: back up the existing database of vcenter, install the new instance of vCenter using the same database (it will overwrite content), then restore the original backup db. Finally, you will need to reset the password for the database command line: "C:\Program Files\VMware\Infrastructure\VirtualCenter Server\vpxd.exe - p. In addition, you must ensure that you restored the SSL certificate, if default automatic scorched Vmware has not been used.

  2. it would work as well. You must create the same name SQL instance with the same name of data base and reposition the connector odbc for the new instance/database. You must also ensure new database has all security configured correctly, for example if vcenter service runs under the specific account, the same account must have rights to the database.

  I'll try to find a few posts on how to recover from these two scenarios, but in the meantime the foregoing, is the answer to your questions.

  See you soon,.

• VCenter server: tolerance on failure service console network

  Hello world!

  I have question about network service on the vCenter Server console. In my server, I have 4 free NIC and I want to lay off the witch NIC network service management console.  Is it a good choice for the team this free with other NIC with Intel Advanced Network Services ( http://www.intel.com/support/network/sb/cs-009747.htm )?

  My 2 vShpere host is configured as scenario 4 illustrated on this page:

  http://kensvirtualreality.WordPress.com/2009/03/09/when-is-it-OK-to-default-on-your-VI/

  My idea is to connect the NIC primary service on the Vcenter Server console to the single switch and the other to the other switch and then the 2 NIC teaming

  Is the right choice?

  Thank you

  You should be able to accomplish what you want by using the NIC software from the manufacturer of your NETWORK adapter in combination.

  Connect the second NETWORK card on pSwitch 2, using the NETWORK card software create a team. Assign the two network cards (same make and model, I hope) to the team. Give the SC IP network to the NIC BIA - clear move the existing IP of the network card.

  If one of the NIC in the server VC port fails and/or a pSwitch fails, your VC server should always be in place.

  Everything else seems good.

• VSphere HA Cluster failure when downing VCenter Server

  Today, I took my VCenter server for maintenance. A few moments later, my node 2 VSphere HA Cluster is gone offline as well as all the guests running. When I brought the server VCenter upward, both hosts HA had to reinstall put it then HA Agent on the guest virtual machines.

  In newspapers, I saw this entry for each host. For the host XYZ.domain.com invited running example 1 and example 2:

  XYZ.domain.com host (data center) does not

  example 1 on host XYZ.domain.com (data center) is disconnected

  Example2 on host XYZ.domain.com (data center) is disconnected

  The other cluster node has a similar registry, where he himself is unresponsive and all virtual machines running on this issue say that they are disconnected.

  Any ideas why this would happen?

  Where is placed your DNS?

• vCenter Server

  In case the server vCenter Server has encountered a problem and needs to re-setup of vCenter, what happens to what follows? They will always work?

  1. high availability

  2 DRS (automatic)

  3. distributed switch connectivity

  4 vSphere replication

  5. Advanced vSphere of data protection

  6 site Recovery Manager

  7 cluster VSAN

  During the time where the vCenter server is unavailable.

  1. high availability - Yes, but the management of Cluster HA is possible only when your vCenter gets online

  2 DRS (automatic) - No.

  3. distributed communication switch connectivity - Yes, the VMs will not face questions, data flow is managed completely by ESXi hosts, but your DVS control plan is not available to change the Setup in it.

  4 vSphere replication - work should, don't know if.

  5 vSphere Data Protection advanced - should work, not too sure.

  6 site Recovery Manager - no.

  7 cluster VSAN - Yes, but the handling of the VSAN that we are using vSphere Web Client is going to be affected.

  and if you need to re - install server vCenter completely. so in this case, you need to take action based on how you re - install your vCenter. For example, if you have fresh installation complete you vCenter server then you need to start building your vCenter Server inventory and take steps to add your ESXi hosts in this new inventory.

• VCenter Server installed as a virtual machine within a ESXi servers it manages?

  Hi all.  I'm new in the world of VSphere... still in my evaluation period.

  I have only a single ESXi server running at the moment but plans to add a second later for high availability, vmotion, increase general capacity, etc.  They are / will be ESXi running on the internal storage and the virtual machines running on a shared SAN.

  Today, I installed VCenter Server 4 on a server at bottom of range/Office that I was carrying around running XP Pro x 64.

  As I was installing I read the guide installation and to my surprise, it seems to recommend that I have installed VCenter Server 4 as a virtual machine on my ESXi host.

  Now maybe I just spent too much time setting up my without new Lefthand requiring a 'witness' during the failover of one SAN to another... but I was under the impression that VCenter Server is not designed simply to host configuration, but is also designed to act as a 'witness' or to take account of quorum whenever a failure scenario occurred on one of my ESXi hosts.  I also noticed the VCenter Server features of a port "heartbeat", which I suppose one would use for the ESXi server heartbeat, but perhaps it is used for "connected mode" with other VCenter servers (I was intending to use only one since it is a small scale installation) I also felt that it would be useful enough to restore a damaged or shot ESXi host.

  So my question is, if my ESXi host dies and it is where I have VCenter Server installed, then high availability will be unable to work?  I guess there are going to be other issues with me unable to access VCenter Server while I have an ESXi host shot, too, as a greater difficulty to get the ESXi up?

  Maybe I'm wrong understand the purpose of the VCenter server... maybe it's not something that's necessary for HA, recovery, etc. and acts only as a configuration tool until something is wrong?  Or maybe I misunderstood the installation guide and they recommend only installing VCenter Server on an ESX box... they don't want this ESX box to be part of the group that manages the server?

  Finally, if indeed they recommend I install this on a ESXi host manages... would I ideally be install this for local storage on the server (where I installed ESXi) or on the SAN (where all my other virtual machines are installed)... or is it just personal preference?

  Thank you!!

  When you add hosts an active hemagglutinin vCenter cluster HA agent is installed on it.  This agent is what is actually the HA.  While necessary to add new hosts in a cluster and configure some specific parameters of vCenter vCenter's agents HA are self-sufficient and can handle HA failover so vCenter is offline.

  You must install the vCenter VM on SAN storage, so that he can use the vMotion, sVmotion, DRS, HA, functions etc. that require a SAN.

• vCenter Server Appliance error 6.0 #1009 after update

  Hi guys.

  A few days ago I updated my client vCenter Server device of vpx of b. 6.0 to 6.0 update works fine, but when I log in web client, I have error #1009.

  

  Journal

  

  I tried all the work arrounds:

  Stop the web client, clear the cache of serenity, start the web client and nothing.

  I disabled the Update Manager and web client and Site Recovery Manager plugins works very well. Then I reload Update Manager and Site Recovery Manager and fails again.

  Update Manager to update to the latest version and fails again.

  Any tips? Help? Wishes?

  I just opened a SR with Vmware, but I don't always have a solution or something. I want to wait for a solution before the restoration, but I can't live without feature Site Recovery Manager.

  Thank you

  Kerchief!

  VMware support solved this situation.

  My browser has settings to Spanish. So, I changed to English languaje of firefox, and the Vmware web client works very well!

  Greetings Vmware support.

• VCenter server restart - can I just it reboot?

  My SAN works somehow, but I can't access my client vsphere vcenter server through.the.  I get the error: an unknown connection error has occurred, (the request has failed because of a logon failure.  Also, I can not connect via veeam.  Everything else seems to work fine.  VCenter is a virtual machine in my SAN environment.  Can - I just restart the vcenter Server?  Or should I stop all the rest down before doing this?

  Thanks in advance for the help.

  Welcome to the community,

  the virtual machines running on the host computers are not vcenter Server, and at least that actions such as migration, backups or other things are underway which require vCenter Server, you should have no problem restarting it.

• vDS and vCenter Server on SAN

  I have a very specific question about it as possible.

  I have 3 guests with no local VMFS (ESXi installed on a Flash cards) and all data warehouses are on the SAN.

  VCenter Server is a virtual machine residing on the SAN.

  SAN access is configured with iSCSI connected through a vDS.

  What would happen if there is a power failure?

  Say that I turn on the SAN first, then try to power on the hosts, the hosts would have access to the San while vCenter Server is still off powerd (and because it's aVM)?

  Thanks for your understanding!

  On VMware ESXi ESX, the vDS configuration is saved on /etc/vmware/dvsdata.db. The file .dvsdata of data warehouses are used by HA and stores some information as the State of the port and its stats.
