• Database and Vcenter linked mode

  Hi all

  I will install 2 Vcenter linked mode, each with him ' s have a local database, on a production site, and another at the recovery site.

  Question: should I make some considerations about the database? I mean, providing that I use the same version of server db on the two sites, do I have to consider other issues? When the production site goes down, I'll be able to use the Vcenter in the DR site with no problems?

  Thank you

  Angelo

  .. just to add a little.  All related attributes is a unique management point only reading.  All instances of vCenter must always be administered separately.

• vCO and vCenter Linked Mode

  Hello!

  are there problems to wait when connecting vCO to a vCenter which is in bound mode?

  Thank you!

  see you soon,

  Joerg

  Hello

  with the exception of the limitations known to vCenter Server and vCenter Orchestrator, I think that there are no problems with this solution. You will need a vCO by vCenter Server instance in enterprise environments. In smaller environments, you can connect several Server vCenter vCenter Orchestrator.

• vCenter Linked Mode and Perl SDK

  Hello

  our VMware environment is divided into two physical places represented as two instances of vCenter. The two vCenters are interconnected. I think that its Mode called "related"?

  Is it possible to use the Perl SDK also bound mode? Currently, I have to manually interrogate both our vCenters and then sort out myself.

  (1) How to configure Perl SDK so I only authenticate once against our environment in Linked mode?

  (2) How can I build queries against the API so results will include objects in the two vCenters? That is to say. If I run a ' Vim::find_entity_views (view_type = > 'VirtualMachine') "I want to get all the objects 'VirtualMachine' in the two vCenters I can avoid running two separate queries and then later combining query results? ".

  Thank you!

  It is not a published API method, but there is a way to get the vCenter server list in a group of related modes.  I have an explanation and sample code: http://www.virtuin.com/2012/12/querying-vcenter-linked-mode-with.html

  With respect to authentication, if your vCenter instances use the same permissions (which is recommended), then it's just a matter to authenticate each vCenter.  This is what the native client as well (if you have never installed vCenters with different permissions, you will see the login for each vCenter prompt).

  If you look at the blog post I linked earlier, you self an example of authentication each vCenter as well.  Basically you call Util::connect() two times, once for each of your URL for vCenter.  However, do not delete the global VIM uses the SDK package, or it will default to the last vCenter.  I show in the example script: LinkedModeExample.pl

  With respect to the combination of queries... not so easy.  You need to redesign each vCenter with $vim-> find_entity_views().  Now on a more advanced note, API is powerful enough to make custom inventory queries, you can usually pick up and keep the updates in your objects.

  What I would recommend as a simple approach is two calls to find_entity_views, then push them in a hash or an array.  You'll just want to use the UUID vCenter:

  $vc_uuid is $vim1-> get_service_content()-> {'about'}-> {'instanceUuid'};.

  The instanceUuid has been added in vCenter 4.x and later versions (do not have in the past 2.5 vCenter instances).  Then use this instanceUuid + moref as hash keys.  This is important because the morefs can be duplicated between vCenters.

  So, you can then create a hash:

  My % vm_hash;

  foreach my {$entity (@$vm_views)}

  My $moref = $entity-> {'mo_ref'}-> {'value'}; # will be vm-# for virtual machines

  $vm_hash {$vc_uuid.} "+". $moref} = $entity;

  }

  Then you can quickly research specific VMs and keep separate them between vCenters.

  You'll find it works for simple data queries, but you start to get more items of inventory (say for an inventory report), the relationship becomes more complex and the number of objects grow.  I did work to push these values in a database and files (including by running it on 5 or less than weight and WaitForUpdatesEx), excel, which works well if you have the time to build the DB and the work of database object schemas.  Just use instanceUuid + Moref value as primary key to prevent any moref vCenter cross reuse value.

  The other option is that the vim reference is added to each object, so you can just get the data of each entity:

  foreach my {$vm (@$vm_views)}

  Print "VM:". "." $vm-> {'name'}. "\n";

  Print "InstanceUuid VC:". $vm-> {'vim'}-> {'service_content'}-> {'about'}-> {'instanceUuid'}. "\n";

  Print "ServiceUrl VC:". $vm-> {'vim'}-> {'service_url'}. "\n";

  }

  I have a project that I tinker with in my spare time (which is rare these days) which aims to consolidate multiple vCenters into one database for queries and reports, but I didn't get far enough away from share it (very rude, but works for a subset of data at present, but it is very effective for collecting loose on<5s intervals).="">

  You can also look into VMware Orchestrator.  Orchestrator can connect to multiple vCenters and caches data for access by automation.  According to your WAN performance, he can work a geographic site and make sure that you need (just watch the moref, names of entities and other potential overlap between vCenters) aggregated data.

• How to clean an installation Vcenter 5.5 missed a second server vCenter linked mode

  Hello

  First of all, my situation:

  I managed to install the following services on a single box:

  vCenter Single Sign-On (Vcenter Single Sign-on to your first server vCenter Server)

  vSphere Web Client

  vCenter Inventory Service

  vCenter Server

  The first properly installed vCenter (SRMVC.test.local).

  I then ran the installation on the second vCenter server (SRMVCDR.test.local)

  vCenter Single Sign-On (vCenter Single Sign-on for an additional vCenter server with a new site)

  vSphere Web Client

  vCenter Inventory Service

  vCenter Server (linked modes) * impossible *.

  I came across a mistake by joining the vCenter linked mode.  I then tried to force who do not have, and installation cancelled.   I think I am facing this problem described in this KB:

  Connecting two servers vCenter fails with the error: error 28039.Setup cannot join vCenter Server group related modes (1026087)

  http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 2006850

  Now, I see a series of problems with the virtual machine that may be the root cause.  When I open the Server Manager there is an error when I try to view the roles or features.   The error I see is:

  Unexpected error refreshing Server Manager: element not found (except for HRESULT:0 x 80070490)

  To make a long story short:

  I don't really want to solve the problem on the virtual machine.  I think there could be a problem with the template I've deployed this virtual machine from and I would just blow it way and the redeployment of a new model. The problem is that, in the previous installs, I had trouble to reinstall a second vCenter after a failure to install because different services have already been registered with the first SSO server.

  My question:

  How to completely clean all the necessary components on the first server vCenter after a failed install a second server vCenter mode related?  I think that the second server is not only with its own UNIQUE authentication server, but also with the first server in the SSO site located on SRMVC.test.local.  I want to blow any trace of it so that the environment is pristine and so that I can use the same name of the second vcenter (VCSRMDR.test.local) when I reinstall.

  If the second vcenter also has its own SSO installed on the same machine and the second SSO has been installed in multisite mode (should be Yes, because the main goal is to related modes), you need a clean to the top of the first SSO vmdrd.

  VMware support specific utility to get this done, please file a case for support.

  Installing vCenter isn't going to be a problem, each installation has a user ID application created with the date of installation, this ID and certificate (which should be unique for a new installation, disable ssl programdata folders if re - install) are used to record vcenter to OSP.

  So the old entries will not be a problem for the other components.

  ever since the webclient service, you can remove users from the application:

  Log webclient with [email protected] the first web client.

  Under setting up users and groups, under the users Application tab, you can see all the application registered users.

  To identify that one to remove

  for vcenter, check the file C:\Program Files\VMware\Infrastructure\VirtualCenter Server\ssoregtool\vssso.properties.

  Once you know the job vcenter ID, you can delete the ID of the other.

  Ditto for the inventory service, the inventory service ID can be found in C:\Program Files\VMware\Infrastructure\Inventory Service\conf\sso.ini

  For webclient files is C:\Program Files\VMware\Infrastructure\vSphereWebClient\SsoRegTool\sso_conf\solution.ini

  vCenter and webclient has a user record solution with sso, which must be removed from the command line. This is the KB for this: 2033238

  again, you can use the above mentioned files to identify the one to delete.

• vCenter linked mode SSO

  Hello

  I am trying to understand the SSO with related modes works

  Today I have a vCenter installed with SSO installed as a base and. Now, I implement SRM here and after I install the second vCenter as base too much on the other site and try to create a linked mode an error pops up

  in ID incompatibility or something like that. I read that multisite is necessary to deploy related modes.

  How can I configure related here, but the problem is that I can't change the basic deployment in the first vcenter because it uses Nexus 1000V is a complex configuration for me.

  I can reinstall the second vCenter because nothing is yet set in.

  Thank you

  Unfortunately because you have it installed as a base, there is no way to install SSO multisite.

  According to the documentation

  "Server vCenter linked mode instances can be connected to different physical servers of Single Sign-On, but must be connected to a single Single Sign-On logical server. An only Single Sign-On logical server can be one of the following forms. »

  With 2 sets of basic mode, they are 2 physical and 2 logical SSO server.

  What should have been done is the first vCenter install SSO on the first node of a multisite SSO and when the second gets installed you create a UNIQUE authentication server separate but accede to the first node. Logically, this will be a single instance SSO so now both servers can be managed from a single web client and can be regulated in bound mode.

• VCenter Linked mode

  Hello world

  I wonder something about vCenter linked mode. If you have two (or more) of vCenters connected through linked modes, and one of them fails for a reason that would happen?

  Could you still manage the vms host, which were managed by the vcenter fails?

  I can find almost everything I wanted to know the documentation and various blogs etc, but this question remains unanswered. Anyone with experience with this issue?

  Thanks in advance!

  Correct - if you lose a vCenter that you lose. Related modes will make no difference in this case.

• Replication between Vcenter linked mode extended

  KIM I am messing with vcenter enhanced link mode. So I have two vcenters shares a PSC external and they are in enhanced binding mode. The problem is when I install my first unit of replication that it installs as MGT. When I install the unit on the second Vcenter he also installs a server. Can't have a primary site and Dr. in enhanced binding mode and use the replication of vSphere?

  Hello

  For the problematic device of VR, you can check the contents of the /opt/vmware/etc/vami/ovfEnv.xml file?

  Normally it is property of deployment_scenario is this file and it is what determines how the device should behave - like handset (embedded DB + server VRMS + VR) or VR-server only.

  If the file ovfEnv.xml is empty, please check that the device has been deployed and powered through vCenter. If the device is powered through ESXi, the environment of the FVO will be empty and VRMS will not work. It is covered in the section of the admin guide.

  If the ovfEnv.xml is not empty, maybe you should file an SR and have the VMware support team assist.

  Kind regards

• vCenter Linked Mode Upgrade w

  Guy.

  I have two servers vCenter running (5.1) and 5.1U1 facility in bound mode. I plan to upgrade them both to 5.5 b and want to make sure that I understand the process regarding the related modes. I feel I will break the connection related modes before starting and then separately upgrade each instance of vCenter. I must point out anything during the upgrade of the main site? I guess I will have the opportunity during the installation of the secondary site to indicate that it will be a linked mode connection? Or this connection comes after the two instances have been implemented. Thank you guys.

  This fence, my response to remove the link between VC and then perform upgrades using multiple single sign - on bodies in different locations and after that the two sites are upgraded to link them returns with the configuration utility.

• disclosure of the API with vcenter linked mode

  The API on a vcenter arrive on an another vcenter linked entities? In the linked vcenter inventory seems to appear anywhere in the CROWD.

  The linked vcenter can be managed in the vcenter gui, but it's just mistletoe knowing to send requests to the api for the other vcenter? The API knows something about the related modes?

  No, he can't manage them. In implementing related patterns as I understand it, it provides you with just the connections for the two vCenter. Linked Mode also uses ADAM to replicate permissions between linked VC, but you must always send API calls appropriate for the appropriate vCenter if you want to perform a specific operation on a given entity. It isn't really a "Federated", but just vCenter allowing multiple connections in a single view or a pane of glass.

• VCenter linked mode filter in the script

  Hey guys,.

  So I have a cli power script that will pull all the virtual machines that are not of the v7 version.

  I have a vcenter vcenter0 who has more vcneters in mode related.

  -vcenter1

  -vcenter2

  and so on. Each vcenter has a cluster of virtual machines in data centers, but when I run the script and log into vcneter0 it pull not vms related alternative vcenters.

  What I am doing wrong and how do I shoot all vcneters vms.

  Help, please

• 5.1 vSphere: manage server vCenter Linked Mode equal redundancy?

  Hi, people. Small question.

  Given the scenario of two or multiple vCenters connected successfully together, if one of the vCenters dies, can the survivors vCenters administer and manage the resources of the server vCenter dead?

  Thank you.

  No.... Related modes do not provide high availability to vCenters, just a single pane of glass with lens for example of ease of management and license sharing.

• Limitations of SQL Express 2005 with vCenter linked mode servers

  
  Hello

  We have a problem at the moment whereby we have reached the limit of 4 GB of SQL Express 2005 and you want to move the database to a dedicated SQL Server. However, one of my colleagues advised he read somewhere that figures recommended for 5 guests and 50 guests for SQL Express are related vCenters signifcantly increased (he thinks a dozen times).

  Is anyone able to confirm/deny this and if confirming point me in the direction of the supporting documentation? I have searched, but am not able to find information reinforcing the above figures.

  Thank you

  Chris.

  Hello

  Recommend VMware SQL Express for small environment, the limit is 5 guests and 50 comments. If you have a linked vcenter environment, you will have a second database for this vcenter. So this vcenter will be able to have 5 guests and 50 comments too.

  But your first database will not increase the limit, you have always the same.

  You can get more information here: VMware KB: vCenter Server 5.0 installation best practices

  Microsoft SQL Server 2008 R2 Express is intended for small deployments of up to 5 servers and/or 50 virtual machines.

  This is for vsphere 5 but the limitation is the same thing on v4.

• Design of 5.1 VCenter Linked Mode Question

  I currently have the following configuration for vCenter 5.1:

  Domain controller Windows 2008 - Windows Server 2008 with SQL Server 2008 vCenter

  Now I have another data center in another part of the region by running its own vCenter 5.1 and adhere to the same domain controller that above; For work-related Mode should I this vCenter server use the same SQL Server or I can configure separate SQL Server for it?

• WILL push in a vCenter Linked Mode

  Hi guys,.

  On vSphere documentation, it says we can manage all vCenters in bound mode. Does that mean we can GO to all vCenters in bound mode, even if the other vCenter is in a different location, say vcenter location B (although the source of the FVO or VA is on vcenter location)?

  If this is possible, then the bandwidth must be reliable and fast enough, what are your takes? What are the limits?

  Thank you

  Marc

  You can deploy one GOES on different vCenter.

  Bandwidth could be a problem.
