Adding new host

We are preparing to add a third host on our site and you need to find out what things I really need to look at more difficult to.  First time addind a solo host so I will try to be careful.  Currently we have 2 hosts running ESX 3.5 U4 and my guess is that the new software license will be 4.0 (VSphere).  I'll need to upgrade the two currents in 4.0 before adding the host or which is subsequently possible.  Any help is appreciated.  Thanks for the time.

You can downgrade the license to VI3 and you should have no problem.  If you want to upgrade to vSphere4, then you first put your instance of vCenter because 2.5 cannot manage ESX(I) 4 guests.

The only weird issue I saw with the hosts 3.x and 4.x, this is what is being talked about in the article.

Finally, if you want to have a mix of ESX hosts, you need to keep your license in tact for the stuff 3.x server

Good luck!

  • Problems adding new host as Eval

    I have 4 hosts in a cluster, all who have exhausted all of the licenses. I have a test server I installed ESX on which I want to just use it as an eval. I created a new data center for it and when I go to add the host I get the error "there are not enough licenses to perform this operation.

    I don't understand why I can't do if I want to just eval this host? It should not need an available license right?

    Thank you.

    You can evaluate it as a facilitator of stand alone, but if you want to add it to an instance of vCenter you must always have available vcenter agent licenses.

  • New host is added to the cluster

    I took over the administration of a cluster 4 host running ESX 4 U1.  The processors are Xeon E5335.  The admin before ordered 2 extra guests with Xeon E5620 CPUs.  I wonder if vmotion will work when I add new hosts, it looks like in KB, I found that I have to change the mask on new hosts and select CVS on all hosts for this to work.  Any help would be greatly appreciated.

    Just turn on CVS at the level of the cluster before adding new hosts. And vMotion works perfectly after that.

  • VMotion IS allowed to new host?

    Hello

    Generally people post because something does not - but I would like to know why something works, I think I should not...!

    I just added new hosts ESXi 5 of my inventory vCenter with Intel X 5675 (Core i7 32nm) processors.  They are not added to a cluster - just at the top level.  Eventually they will succeed the existing cluster, which is comprised of 3 servers ESX 4.0, using a 2 Core (with E5440 & 5160 processors) VCA

    Now, I wasn't expecting to work, but I gave it a shot anyway, and it allowed me to VMotion in the former EVC cluster (in Core 2 mode) and the new host - once again...

    If it works?  This means that virtual machines are still using the Core 2 mode on the new servers - even if they are not in a cluster of VCA?  Where we are today able to migrate computers through the generations of processors?

    I will say that it is because of the function defined CPU provided by your CVS base is based entirely on your host target outside the cluster...

    If you power off the virtual machine and it still works on your new host, thus exposing the new features of the virtual machine CPU, virtual machine fails try to migrate to the VCA pole...

  • NFS share for one (1) added when adding to a new host in the existing data center

    I'm sure it's a simple answer, but I've been beating my head on the wall, trying to find a solution. The scenario is as follows:

    1 Vcenter has several hosts in different groups. All built at the same time with a NFS share that is shared among all.

    2. I add a new host to the data center (I tried independently and also added to a cluster as well).

    3. the new host sees its local disk as a data store, as expected, but I have to add the shared NFS datastore.

    4. at the level of the host, I go to configuration-storage-add storage and the NFS share.

    It shows and normal with NFS (1) as the name. I can't rename it as it says THAT NFS already exist. I understand that there are in the vcenter DB, but how to add this new host or host an existing environment and maintain the name of the NFS share? vCenter 5.5, 5.5 esxi

    Thanks for your help

  • Adding a new host to the existing cluster

    Hi all

    The existing cluster has a connected SAN. Should what precaution I look forward to add a new host to the existing cluster? I did research that we should physically disconnect the HBA before adding, I don't know what it is to be honest.

    Thanks a lot, guys

    Please, how can one more thing I change the host name?

    Appreciated all your help

    Kind regards

    Hello

    Once the host is already in the vCenter inventory, you cannot change it, you must disconnect host to vCenter, delete the inventory and add it again using a different name,.

    for example, if you specify IP during the connection wizzard, it seems in vCenter inventory under an IP address, if you want it to be visible as a hostname or a domain FULL, during the wizard name you used its hostname or FULL domain name

  • No network connection to the virtual computer after migration manually to the new host

    We have added six new hosts to our environment, and I was tasked to test connections of VIRTUAL LAN on each of them before we move VM production of their.  This is probably a simple problem, but I am new to VMWare and need help.  I already talked to our network guys, and he assures me that the physical switches are setup and working properly.  We work a vDS.

    I'm testing 14 VLANs on six new hosts.  All but one are constantly working.  (They all work on the hosts of origin which were in force before.)  I have a static IP configuration on my test VM and MAC is set to automatic.  I checked the MAC does not change when you migrate to other hosts and the VLAN correct is listed in the settings the VM network (it is not empty).  Him VLAN will work on three of the six hosts, but not all at the same time.  The strange thing is that guests at work are constantly changing.  For example, this morning hosts11, 12 and 14 may work, but this afternoon, that could change at hosts12, 14 and 16.  I don't understand why they would change on their own.

    My test consists of VM testing, migration manually, powering back, then he ping from my computer off.  Of course everything works when I get ping responses.  When I get no answers, the test of the virtual machine has a yellow exclamation mark on the network icon in the system tray.

    What should I do to fix this?

    How is the network configured?  You have a different NIC port/cable for each VLAN or Trunking used on the side of the switch?

    If you use circuits on the side of the switch, then your GRPE ports virtual switch a VLAN ID needs to match the vlan is underway to shared resources.  No matter if it's a standard switch or switch distributed... you still need this ID of vlan.

    I've seen the random question that you encounter if missing one or more of of the uplinks on the side of the switch the VLAN.

  • Create the new host to the Cluster and Cluster

    Hi team,

    Have we not document or steps to create the new Cluster and add host to cluster?

    In addition, what are the post configuration that must be done on the ESX host? As switch, Nic, the data store Configuration?

    Should we add the storage front of cluster before adding the host?

    A process document or a step will be really useful.

    We plan to automate the process and any entry is really useful.

    Thanks and greetings

    For starters, it is User Guide PowerCLI, that comes with the installation of PowerCLI.

    And there are a lot of messages and blog discussions in this community that meet some or all of your questions.

    See for example establishment of data centres, Clusters and adding ESXi host VMware vCenter 5.x with PowerCLI

    Storage is assigned to ESXi hosts and for use in a clustered environment, you will probably want a shared storage.

    Maybe you need to split issues separate, more specific issues.

    This would make it easier to respond in this community.

  • Add new host esxi 5.1 for the existing cluster of vcenter

    Hello

    I would like to add a new host Virgin esxi 5.1 to an existing cluster from the vcenter. What are the things that I have to preconfigure on the host before add you it? I configured the network already, storage will be implemented when I add it to the cluster, right?

    So, what I ended up doing was just set up time, networking and dns. I then added the host while he was in maintenance mode. I have a Compellent SAN storage and im using a folder in compellent to map all my Lun, then I can just add a new host in this folder, and it will automatically map all volumes to the newly added host once I go into vmware and make a new analysis on the FC HBA host (do FC fabric SW zoning first of course). I then added a file .locker on one of my SAN LUNS scrach location/newspapers. She's.

  • Problems with the new host VMware ESXi 5.0

    We have a dell blade chassis, with 4 710 blades and 8 610 the 710's have 12 network cards and the 610's have only 6 network adapters. I added a new host on one of the 610's and two network adapters in each of the networks belonging to virtual infrastructure. 1 mgmt 2. ISCSI 3. vmnetwork

    My problem is that the new host can see all the resources but I can't move the VM from the hosts to the host 610 710. I get an error because nic 2 on the 710 host is not in the same network as nic 2 on the 610. It seems silly that I wouldn't be able to do that just because the hardware is not identicle.

    I have three vswitches, vswitch0 for management, vswitch1 for the iSCSI network of shared storage, vswitch2 for the network of the vm.

    Thanks for any help.

    Material is not identical not should not have an impact.

    The vSwitch port group to which are connected the NICs in question is named identically on both hosts?  If they have a different name, vSphere considers different networks.

  • New host, existing LUNS, see device but will not add datastore

    Hi people,

    We have 2 free with an iSCSI target each and three ESXi hosts to their use. We also have VCenter.

    We have added a new 4th host. He can see the SAN devices and connects very well from the point of view iSCSI (confirmed both ends). If we look at the way we see the VMFS partitions and different paths. The location and IDs are all the same and all seems good. But, view that we see no data warehouses and a refreshment or a new analysis found in the data stores.

    We have added a new this new ESXi host iSCSI target and can see in all the others with a refresh. We can also add this host to vCenter and tried the above through vCenter both directly on the host computer. We also deconfigured and disabled the adapter software again.

    The only thing I notice is the runtime name is different for these two channels on the new host for others, but it is also different for the new target of the test and works.

    Can anyone offer pointers? We can do something necessary to this host but cannot disturb the San for obvious reasons - that shouldn't be necessary, however, because they show the iSCSI host connections.

    Thank you!

  • Failed to configure HA on a new host

    Here's the scenario...

    I added a new host for my cluster existing, reproduces all the components of network correctly and can ping the new host name and IP address of the network and the vcenter Server and the license to the new host file allows HA.

    The question I have is that when I try to activate HA on this host, it fails every time with the following message appears: -.

    HA agaent has an error addnodefailedforprimarynode: cmd:

    AAM error - internal agent could not HA start.:Unknown error.

    Can someone help me solve this problem or at least point me in the right direction.

    See you soon

    Take a look at the Configuration of the host tab in the vSphere Client. Make sure the entry field (and search) in 'And DNS routing' exists and is correct (for example, a typo in).

  • I can't power on a virtual machine (with linked disks) after the addition of new hosts of Lab Manager

    ENVIRONMENT

    -Lab Manager 3 using VC 3.5

    -Initially the 2 hosts in a cluster and managed by LM

    -Added new cluster with 2 new hosts in VC

    -Two bunches pointing to the same NFS storage

    PROBLEM

    -When you try to turn on a computer in new cluster, I get a "requested file" "not found" error

    RESULTS

    -This seems to happen only when creating a virtual machine that has virtual disks of parent; most of our VMS is linked clones

    -When you look at the log file, please see attachment, we found the following:

    It is the location of the new virtual machine in the new host:

    /vmfs/volumes/fabdf38d-beff047d/LMW2K3/2909/002909-T_XP_SP3_32b.VMDK

    When you look at the hard, it points to the parent disk, but it seems that it does not:

    /vmfs/volumes/6586c772-53eee1bb/LMW2K3/2904/002904-T_XP_SP3_32b.VMDK

    Please note th volumen IDS are different and can not get the disc parent of the new machine.

    SOLUTIONS?

    Thank you

    Jose

    You should immediately stop using the new hosts otherwise creating new virtual machines can spoil the vmdk channels. Try http://kb.vmware.com/kb/1005930.
