Cluster with different host - resource pools hardware?

Similar Questions

• Keep the host resource pools after leaving a cluster

  I thought is was impossible to keep existing or cluster transplant pools of resources on the host which prefabricated a cluster.

  However, vSphere resources management Guide of reading I found an interesting note:

  Make sure that you remove the cluster host by placing first in maintenance mode. If you
  instead disconnect the host before you delete the cluster, the host keeps the pool resource that
  reflects the hierarchy of the cluster.
  

  It looked like something, so I tried it but no luck, the host had no pool after removed offline.

  Now I'm confused of what this phrase actually means.

  What do you see when you connect with vSphere client directly?

  Usually, I see ONLY the list of the running virtual machine resources... not all resource pool.

  Without virtual machines so I think that all the resource pools are removed.

  Try to disconnect with some VM running (also false VMs).

• pass fails with a missing resource pool alert

  Hi, I have a server dell power edge r510, with ESXi 5.0 is installed in it.

  in one of the virtual machines within this server, I installed Vcenter (I think that it is Version 5.1) everything was stable until the vcenter database gets 10 GB and crashed and I couldn't fix it. So I installed a new windows with vcenter 5.5 inside vps. and for this new vcenter reconnected to the server. so, I've reconfigured resource pools and VPS users again in this new vcenter.

  Watch ESXi host now as does not not to the vcenter. but all virtual machines inside the esxi server work without problems.  I can't reconnect to the host in vcenter, and I can't connect directly to the ESXi via vsphere client and root password.

  but I can log on to the esxi via ssh or console.

  from the console, I restarted the management services, but it does not help.

  the SSH, I ran the following commands:

  status /etc/init.d/vpxa #.

  vpxa is running

  status /etc/init.d/hostd #.

  pass is not running.

  When I restart pass, it is said has started, but after a few minutes still pass fails.

  How can I change the list of resources of the VM to ssh when esxcli do not work?

  I am facing this problem recently, almost all the 5 days the server will respond is not in vcenter, restart the entire esxi server can solve the problem but it apears again.

  I think that resource in vcenter pools doesn't sync properly with the configuration of esxi, as when I connect to the server directly with root/vshpere it shows different configuration than what I see in vcenter!

  and I can't upgrade esxi host because there are about 10 VPSes important and stable running on this server which is my main server and I can not have time on this server or migrate virtual machines to a different server/IPs.

  because I'm not sure of the compatibility of the versions of drivers/bios nic with ESXi 5.5 and I fear that if I update the ESXi from 5.0 to 5.5 I face other questions strangers/downtime.

  I had the server up and running again, by editing this file: /etc/vmware/hostd/pools.xml

  then I found the VPS with id of the pool of resources 11 evil, changed for another pool of resources as the other virtual machines.

  and then made a

  restart the /etc/init.d/hostd

  all started working again without restarting the whole esxi server and turn off virtual machines, I have searched for about 1 day to solve this simple thing!

  even once when I made a few changes in the vcenter, and then restarted resource pool settings move it in ssh, it fails under vcenter changed the VM resource for a bad configuration pool.

  so I changed the resource pool manually xml and restarted spend, while vcenter can connect to the esxi host.

  then vcenter, again removed all the resource pools and created new resource pools. and this question of time is set.

  There was some resource pool configuration that was imported from esxi host to vcenter which was no longer available and has not been deleted in syncronizations between esxi and vcenter when changed resource pools. and the list of the missing resources caused problems.

• Add esx cluster with different cpu

  Hi all

  I have a cluster with 5 esx 4.0 u1-208167, which installed on IBM x 3550 M2 ((2 x Intel® Xeon™ processeur E5520) .)

  I want to add a server to server cluster .the is IMB x 3550 m3 (2 x Intel® Xeon™ processor E5620 4 c)

  do I have to make a chenges on Esx servers / vm / vcenter when I add the new esx for my datacerter and to the cluster so I can do Vmotion / storage migrate this server in the cluater (I have the appropriate license and plug)?

  Thanks for the help

  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.

• Actually an ESX cluster with different times may have problems?

  Hello

  Recently, I hired a company to install a cluster EXES 3.5.

  After leaving, I discovered that the two machines, ESX1 and ESX2 have hours different (about 12 hours difference). The company said that it is impossible that the two machines have the same time, because I don't have a time server on the LAN.

  I am facing many problems with the cluster.

  Some of the machine should ocupy 100 GB and 200 GB are using (I have no pictures of this machines)

  When my VM SAP jumps from ESX1 to ESX2 services down

  The VCB does not detect the majority of virtual machines and I can't see them on BE 12

  The problem of cluster could be related?

  Thanks in advance,

  Luis Estevens

  You really do need get guests in sync. As has already been noted SAP (or any database system) will not be as if all of a sudden she is 12 hours in the future or the past.

  If you do not have an internal time server (there are a couple of freeware NTP servers that run on Windows) you can use an external time source. I use pool.ntp.org (http://www.pool.ntp.org/en/use.html) it is a great service they have around l 'Robing' between the time sources. For this he both ESX hosts should be able to make outbound connections to port 123 (NTP) UDP.

• vSphere Cluster with different Versions of ESX

  We plan to upgrade our ESX ESX ESXi 5.1 4.1 host our preferred is method of upgrade via the Update Manager. In the 5.1 Update Manager documentation it provides the following:

  "ESXi 4.x to 5.x UPGRADE ESXi is supported and ESX 4.1 for ESXi 5 MIGRATION is supported. Anyone know what are the difference between an upgrade and a migration? Am I'm going to completely rebuild the host or will it keep its settings.

  Also run different versions of inside ESX (ESX 4.1 and 5.1 ESXi) the same cluster, supported? Any other consideration when running different versions of the same cluster. It will be a temporary problem while we work to get all hosts upgrade.

  Thank you.

  Migration - is where you perform the migration of ESXi 4.x for a new installation of ESXi 5 x

  Upgrade - is where you upgrade the existing ESXi 4.x host which will allow you to save the configuration of the host - things to keep in mind before you go is to ensure that existing equipment is supported by ESXi5 - you want to place the host to be upgraded in Maintenance mode - vCenter must be upgraded first

  As long as vCenter is upgraded to version 5.x versions of ESXi can coexist in a cluster

• Cluster with different versions of ESXi - version vCenter

  I have a 2 cluster nodes ESXi 5.0.0.

  I intend to spend one of the 2 nodes to ESXi 5.5 U2 by inserting the CD of U2 ESXi 5.5 in the CD from the host and performing an upgrade: is there a question I should?

  Since a few days/weeks, I can't upgrade the second node.

  Is there any problem if one of the 2 i ESXi 5.0.0 and the other nodes is 5.5 U2?

  I plan to upgrade my vCenter as well after the upgrade to 2 knots. Where can I see the version of the vCenter (a virtual Windows VM)?

• Can you have a cluster with a single host?

  Hello

  I'll put up a new VMware infrastructure, which includes a cluster with 2 guests in a place and a single ESX host in a second location.  They will all be managed by server unique vSphere.

  It is possible that the second site can earn an additional ESX host at some point in the future.  So, my question is if I have to create a cluster for the second site and have just the single host in it for now, so its ready if we add a second host?  Is it possible to have a cluster with a host, and what are the consequences of this?

  Thank you

  Joe

  Technically, Yes, you can have a Cluster to a single node and if you plan to add another node in the cluster later it makes sense to set up the first node.

  And, both from a technical point of view, but especially from a point of view BAU.  Mulitnode cluster promotion will be less intrusuve there is no additional software to add on the pre-existing main node, therefore you Board change will be less nervous about the piece of work, because it won't change the node pre - that does not exist.

  From a personal point of view my current client runs a number of single-node clusters, in their environment.

• Question about Lab Manager and ESX Resource Pools

  Hello world

  I was wondering if I can get feedback from some of the members of the community.  We used Lab Manager very strongly in our support organizations and it has proved to be a valuable tool.  Recently, we collaborated with the Department of technical training and started hosting online seminars and classes for them using Lab Manager.  Last week we had a fairly large class of users (approx. 45), each duty deploy 2 rather Beefy VMs that were very intensive resources (Jboss, SQL, Mail to name a few).  My colleague and I went through a lot of trials and planning to ensure that our infrastructure can handle the load while allowing our users to date at the same speed and reliability, so that they are used.

  Our Lab Manager ESX server pools made up of the following:

  5 HP DL380 G5 servers with 2 x Quad Core 2.8 GHZ processors (8 cores each) with 32 GB of RAM each

  2 HP DL580 G5 servers with 4 x Quad Core 2.8 GHZ processors (16 cores each) with 128 GB of RAM each

  When the class is running and everyone has made their 2 machines, we noticed for some reason, he was all on ESX2 and 3 deployment (380 s).  Then came the ESX alarms, use of 90% of memory, then more than 100% bringing the disk page.  The CPU usage was at a all time high.

  I look at the 2 580 s and there are about 4 virtual machines deployed on them.

  So my question is...

  How does he know where to launch a Virtual Lab Manager machine?  There's no sense 2 servers have been brought to the red zone, and almost overloaded when the 2 most powerful servers in my farm are nearly dormant.  I noticed sometimes in the past, but not this bad.  Normally, we have about 45-50 computers deployed at some point and it seems to spread them out properly.

  This group of training has access to the same LUN and ESX server with Betclick as any other organization that we have.

  We have decided hosting several sessions of training may be greater than this one and would like to know that the virtual machines will be distributed properly.

  I would like to know your opinion on this

  First to answer your question, then make guess what happens.

  As indicated in response Ilya, LM distributed VMs differently with active DRS resource pools and pools of resources without active DRS.

  LM place VMs when the DRS is not used.

  When DRS is used, we use the DRS admission control to select the host to place virtual machines.

  DRS is turned off, LM uses its own placement routine:

  For each virtual machine, LM filter all managed servers that cannot run the virtual machine. A complete list of patterns are:

  • The managed server has not enough memory or quota for virtual machine to run the virtual machine.

  • The host is not connected to the data store that is the virtual machine.

  • The virtual machine has active state (suspended) and the CPU of the server managed by the waking state has been captured is not compatible with the managed server currently considered.

  • The virtual machine has been a guest on 64-bit and the managed server is not 64-bit capable.

  • The virtual machine has more processors than the managed server.

  • The managed server is not accessible or is set to "prohibit deployments." Not reachable may mean that the lm-agent or its not to ping queries is not answer (this is visible in the list of managed server page).

  Once we have the complete list of eligible servers, we place the virtual machines on the host including the smallest (MemoryReservation % + CPUReservation %). By default, we reserve not CPU on LM VMs, this internship will be largely due to the memory on the host computers if you have not changed the settings of reservation of CPU on your virtual machines.

  For closed deploy to the PF3, force us all virtual machines to go on the same host, so if any virtual machines have any special data store / CPU type specification, all virtual machines is forced to go on this host. If there are conflicting requirements between different virtual machines in the same configuration, deployment will fail. Closed VMs also have another condition to check that is rarely achieved in practice: number of closed networks available on the managed server. By default, this is 20 and you will need more than 20 different configurations closed running on a managed server before you who will strike.  (LM4 allows Cross fencing host, so this does not apply in LM4).

  To make a guess blind because of your distribution problem - if you use the saved state and fencing, it's probably the type of processor.  Processor type can be checked on the host properties page.

  If you not are not I would check that the images can deploy on the 580 s by disabling the 380s and trying to deploy them.

  If you use DRS (which you're not), it could be due to deployment of virtual machines too fast for the algorithm of control for the entrance of VC.  An easy solution for this is to extinguish the DRS on the cluster manager of laboratory.

  We tested load internal repeatedly, the product QA in different laboratories, we run (LM has been used in VMworld Labs for the past couple years and internal systems of training and demonstration for our Organization implemented SE), so no need to worry about this.  I assure you that the first 'real' performance problem you will encounter will be almost certainly due to an overload of your storage array (too many IOPS / s)... and for that you have to distribute content in data warehouses and use techniques of creating paths to balance the load.

  Kind regards

  Steven

• Monitor the IOPS / s in a Resource Pool?

  Hello world

  I am quite new to vROM and just get your feet wet for me.  I've been delving into the book "Mastering Operations Manager vRealize" useful and which was helpful, but I'm trying to understand an important piece on:

  We have pools of different resources for different departments within our Organization, and I try to get a good graph for IOPS / s in each resource pool.  I was able to get a list of all virtual machines in a resource pool by creating a dashboard with the widget resource pool game object selector, then use "Diagnose e/s disk of the Virtual Machine list" view to see all the virtual machines within the list of resources and then for the summary allows you to SUM add them all together.  This gives me a number, but does nothing for this over time.  I'd like to be able to see that number over the next few months (even if it means just go ahead of data today onward, not historical).

  Any ideas?  I think I must be missing something, like the Resource Pool looks like it would be a good way to measure the impact of the drive.  Folder of the Virtual Machine might work also, but is not as clean as I would like.

  Hello world

  Right after I got this resolved so I thought I would mention it here in case anyone else is curious.  It has to do with the SuperMetrics.

  The formula I created is as follows:

  SUM (${adapterkind = VMWARE, resourcekind = VirtualMachine, attribute is virtualDisk | commandsAveraged_average, depth = 1})

  It takes the sum of all virtual machines to a level under the resource pool.  I also used average and Max values, because this helps to show trends and you have aberrant VMs eating a ton of IOPS / s.

  I received lots of help from Iwan Rahabok virtual red point.  Specifically, this thread here: http://virtual-red-dot.info/any-vm-abusing-your-iaas-by-doing-excessive-workload/

• Is there a default resource pool?

  All - I read the white paper on esxtop that was written by Scott Drummond and can be found here - & gt; http://communities.VMware.com/docs/doc-9279 In this one, page 9, under the definition of 'State', he said:

  While the state memory of the host is not used to determine if the memory should be retrieved from virtual machines (which
  decision is made at the level of the resource pool), it may affect what mechanisms are used to retrieve the memory if necessary.
  In the States high and soft, ballooning is favored over permutation. In States hard and low, swapping is favored by report
  balloon flight

  So my question is, what happens if I do not defined resource pools?  Is there a default pool?  If not, are there any rehabilitation of the memory available for my guests/guests?

  "Every independent host and each DRS cluster has a pool of resources of root (invisible) which brings together the resources of the host or a cluster. The resource pool root does not appear because the resources of the host (or cluster) and the root resource pool are always the same. "- extract from http://pubs.vmware.com/vi35u2/resmgmt/wwhelp/wwhimpl/common/html/wwhelp.htm?context=resmgmt&file=vc_resource_pools.5.2.html

• use different JADs to deploy a COD with different properties

  I've never had different JADs to work for the Web site deployment.

  This is the problem, I use getAppProperty MIDLET to get a property.

  I create a file myMidlet.COD with myMidlet.jad which has a property of the HOST.

  I have ten different JADs with different HOST property on a Web site for

  a myMidlet.COD that will be deployed. The midelt deploys nicely on the Blackberry

  but the HOST is the same as that used to build cod. They gave me a code snippet and

  I use the function mybbProperty.getAppProperty ("AppMyHost");

  I noticed that the getFriendlyName() is the name of my Application, so I use it and

  print information. Did I get this

  mybbProperty mybb = new mybbProperty();

  String s = mybb.getAppProperty ("AppMyHOST");

  myMidlet

  * Found

  * myMidlet-3

  * myMidlet-2

  * myMidlet-1

  of course, which returns null. So how do JAD another properties which was used to deploy the

  App for Blackberry. In Nokia its pretty simple use MIDlet getAppProperty() you need a jad and jar for

  deploy it.

  In any case, I don't know which module to get. The JAD I used to deploy the cod was called green.jad

  so I have no idea why myMidlet is important. I wouldn't see green.jad somewhere?

  Anyway, I would appreciate any code that does this correctly.

• 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.

• MSSQL server VM cluster should be in the same host or different hosts with RDM

  Could someone me on how to place the code SQL cluster s VM with RDMs in ESXi hosts for advice.

  What is the best practice to place the SQL VM s in ESXi hosts.

  Affinity or an anti-affinite...?

  Appreciated your valuable answers.

  Depends entirely on the use case.

  • 2 MS SQL nodes on the same host to see the availability of the software
  • 2 nodes on different hosts to see the availability of the equipment

  I'd say MS Clusters on the same host (at the time of HA and vSMP FT) are redundant VMware features and represent an increase in management fees. The MS cluster on hosts provide something in addition to what VMware vSphere alone can provide!
