Storage available only on a host in a cluster

I'm having a strange problem with storage not appearing is not on more than one host. Here are the details:

I've recently updated vCenter Server to 5.5. Guests still running 5.0. I have a production data center that works very well, and I have a backup site data center. The backup site data center is having this problem. I got an existing LUN copied on the hot site SAN and presented to all hosts on the hot site. I rescan for the new storage and guests see the new LUN and everything looks good there.

When I go to the store to add, this is when I see this problem. I go to the first host, storage add, add the LUN, it sees, reads the VMFS data correctly and adds it and it appears in the list of storage. So far so good. He reanalysis for VMFS on other hosts, but they do not show the new storage. I have manually rescan and still, they do not show the storage.

If I remove the LUN from the host first, go to another host, add the LUN, it reads very well, he presents in the storage and works OK, but then none of the other hosts see it, even one that comes if she had on her and she saw OK.

The production data center and hosts are works well, adding LUN functions normally, it's just this data center hot site I see it on.

Does anyone have ideas, what happens?

Thanks for the tips

  • How to force use of the VM a specific host in a cluster?

    I use vSphere vSphere Web Client 5.5 thru 5.0U2.

    When I create a virtual machine, I specify a host in a cluster as computing resources.  However, when I turn on the virtual machine, it uses another host.   How can I configure the virtual machine to use only a specific host in the cluster?

    Use the DRS-> Virtual Machine Options to disable the level of automation for the virtual machine. Who will be actually anchor her to this host. You could also put the VM on local storage or attach too to a resource (DVD-ROM) on this host, but the road of the DRS is the best way to go.

  • Cluster of RAM available vs ESX or host available RAM systems

    I downloaded ESXi 4.0 to play with HA and DRS etc on some not very new material that I managed to combine. I have two hosts ESX, Virtual Center and a NAS box.

    Unfortunately, the ESX hosts have only 2 GB of RAM each.

    When I put the hosts in the cluster and look at the resources available cluster I don't have that 319 MB of RAM available - even if there is no virtual machines running.

    Each ESX host has more than 1 GB of RAM available - I wonder what the circuit breaker is here?

    This apparent lack or RAM means that HA does not have enough resources to set up a HA cluster for example...

    ESXi 4 requires 2GB for himself. In fact some less than 2 GB, but make sure it as a starting point.

    All the memory you want to give the virtual machines - should be greater than 2 GB.

  • incomplete printing of letters, but only from the host computer

    I have a recurring problem with my print where the last line of each paragraph does not correctly print outs.  the bottom of the letters are cut off.  In addition, this problem occurs only on the host computer in our network.  and maybe when I use microsoft word, excel or publisher. (I print web pages properly) I did the following:

    1 printer checked drivers were updated and they are.

    2. ran a clean ink cartridge program, did not work.

    3. install new, both ink cartridges in black and color.

    4. selected 'best' for the quality of printing, this improves the problem but does not eliminate the problem.

  • Raw disk used by the prompt on the same host, broadcasts available on other hosts in the Cluster

    We have a Cluster of MS using RDMs in a host cluster ESXi 4.1 5.  The RDM physical Mode, on a guest on hostA, the storage is presented to the host b, hostC, pass, hostA, hostE.

    It has always been my understanding (and I saw with other RDMs in the past) when a ROW gets used by a hostA of comments, it will be posted is no longer in the pool of strage avalible under the window "Add Storage" on the host b.-e... I would still be able to see as RDM LUN if I went to a guest and added another hard drive, but the host would no longer display it as storage avalible.

    It is confirmed in the following article: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1016222

    In my scenario, I can still see the storage that has been given to a guest on HostA as a RDM on hostsB-E in the add storage window. (this cause some problems when let storage recover 'unused' LUNS and storage that has been considered as non-allocated was actually released several guests as RDM.)

    The article suggests that this occurs when the storage is not presented consistently on all hosts in a cluster.  We use EMC FC storage, and my storage administrators swear that LUNS are the same for all hosts in my cluster.

    I search in the KB articles information and empty to come... I'll open a case with VMware, but was wondering if someone else has experienced problems similar, and that has been done on your side to solve (and hopefully help someone to avoid any similar problems)

    In addition, there is an easy way to compare points of view "Add Storage" of all hosts in a cluster to verify that they see the same unallocated storage?

    No, if the number of LUNs and the naa numbers game (don't forget the 16 and the last 8 digits of number of naa are still the same according to the table), you can have row filtering disabled Please check

  • where to check the availability of the esxi host?

    vsphere 4.1 customer, where can I go to check the availability of the esxi host without going to the terminal of the esxi host?

    Hello

    You can find uptaime or ALL your ESXi servers in the data center in this way

    Click on the vCener Server (left site)--> hosts tab in the window on the right and on the right site, you will see availability for all guests

    Can host pause a participating video for all participants?  Documentation said yes, but when I test it stops only on the host screen.

    I think you're right. When you stop your video stream live, he stops for all participants. When you stop the video stream for someone else, you pause for only yourself.

    I see nothing in the documentation to force a break from the other video. What documentation you are looking at? Adobe Connect 9 * video in meetings

  • License question - do need me a VSAN license for all hosts in a cluster?

    I have a 6 host cluster exist using the VSphere Essentials Plus package with a single server VCenter. Can I buy x VSAN 3 licenses, for example to add the storage to the 3 hosts I have install the VSAN license on and access the VSAN of the 3 other hosts in the cluster data store? (Assuming only 1 CPU for each host.)

    Thank you!

    Hi Daniel,.

    Since Virtual SAN is activated at the level of a cluster, all cluster hosts can consume storage since the virtual SAN data store regardless of how many guests contribute to storage. So to answer your question, you need all 6 hosts in your cluster license, even though only 3 of them contributed storage.

    Also note that the licenses are per CPU so in your scenario if each host has 2 CPUs, you need a total of 12 CPU licenses. I hope this helps.

  • Share of CPU between ESXi hosts in a cluster?

    Is it possible to configure a cluster with a pool of CPU resources such as all CPUS of all ESXi hosts in the cluster are in the pool and if a virtual machine starts using more CPU that's current host has it can draw another ESXi host CPU to deal with?

    A virtual machine can use CPU only from the host where the virtual machine works... There is no way to allocate CPU of multiple hosts to a single virtual machine.

  • 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.

  • Maybe to lock a virtual computer to a host in a cluster?

    Hello!

    We have a virtual machine that will require a special material (to test it). We step only HW in an ESX host in our cluster. Is it possible to lock the only VM in this specific host?

    Concerning

    H

    With vSphere 4.1 DRS host-affinity has been added (see http://www.vmware.com/files/pdf/techpaper/VMW-Whats-New-vSphere41-HA.pdf), you can set a 'must' rule to ensure that the virtual machine only works on a specific host.

  • Locking of the VMS in specific hosts in a cluster

    Is there a way to limit a virtual computer to a specific set of hosts in a cluster?

    I have created some DRS rules to separate and solidarity with virtual machines, but can not find a way (when it exists) to keep VMs locked to a set of hosts in a cluster.

    For example.

    8 guests: 6 with 16 GB of RAM and 2 with 32 GB of RAM

    2 development servers that will use 8 GB RAM each

    I want to force the dev VMs. 2 to migrate only between 2 hosts 32 GB while allowing the other VMS migrate freely among all the guests.

    Any ideas or suggestions are welcome

    Thanks in advance.

    DRS work in the field of the cluster, so there is no way actually lock VMs subset within the cluster

    If the creation of a separate cluster is not an option, a solution would be to keep the level of automation for those virtual machines to partially automated and then apply that recommendation which moves them to the desired hosts. Not a very optimal solution but it always work for non-critical virtual machines
