Lost of acceso del cluster Datastore iSCSI cuando uno los back switches caer al vSphere

Hola,

Estoy serve a vSphere en alta availability, conectado al por iSCSI storage environment. Detallo el entorno:

Back switches Procurve 2920 connected between por ellos a trunk con back cables from FC con una VLAN para iSCSI.

An experience past 1 G an iSCSI, cada uno conectado a uno los con servidores Proliant DL360 Gen9 red back of back ports. Con el por iSCSI initiator software from VMware.

Storage formed por back nodos HP 4330 en cluster, cada con UN nodo StoreVitual-dependent back red puertos y cada puerto a one of the switches

The config as he hecho Los nodos vSphere ha sido a vSwitch, con VMKernel back in the same red y las back vmnic, each of ellas activa en UN vmkernel y unnused in el otro, las following past of vmware. The balanceo politica're RR.

TODO works correctamente, except in el momento in el as el switch Procurve 1 cae. Cuando esto happens to pierde el acceso a los data warehouses in los nodos ESX, voy al vCenter until back y en the config-> storage, the doy pestana a Rescan All, momento in el than vuelven a appear.

¿alguien could help me a saber porque esto happens y como lo puedo did?

Gracias,.

Ya hemos sown el problema, y the respond.

Esta spend las premium MAC por un switch del puerto y por el trunk al momento apagar el local switch, esas MAC duplicadas corresponden a los vmk of vMotion. Para el trafico vMotion tenemos breakfast back redes independientes as no switch should dirty cada don't con lo than no hace falta that vean between switches. Hemos quitado esa vlan trunk del there is no tenemos el problema!

Saludos!

  • a new datastore iSCSI (disk/lun) appears in the inventory. Warehouses of data, but not availble for quick vMotioning...

    Hello

    We have added the new datastore iSCSI (disk/lun)

    This new data store appears in the inventory. Warehouses of data, but not availble for quick vMotioning or the creation of a new virtual machine.

    did we miss a step?

    Ty

    r

    The reason is that the data store is not presented to all hosts in a cluster. When you create the VM in vCenter Server, only warehouses of data visible to the host on which the virtual machine is created are displayed.

    Make sure the presentation on your storage system is correct and rescan your hosts.

    To check the above, take a look at the Configuration-> Storage for guests.

  • Lost my outlook express 6, how do I get it back?

    Lost my outlook express 6, how do I get it back? Happens if I turned off my PC and sometimes medication back with all my lost addresses and emails. I perfer to any other email outlook so please help!

    Define lost. The shortcut icon is missing?

    Right click on the desktop | New | Shortcut. Navigate to "c:\program files\outlook express\msimn.exe". Click next | Click Finish.  It will be a new shortcut on the desktop.

    Outlook and Outlook Express are different programs, so please watch your shortcut.

    General precautions for Outlook Express:

    Do not archive mail in the receipt or sent items box. Create your own user-defined folders and move messages you want to put in them. Empty the deleted items folder daily. Although the dbx files have a theoretical capacity of 2 GB, I recommend all a 300 MB max for less risk of corruption.

    Information on the maximum size of the .dbx files that are used by Outlook Express:
    http://support.Microsoft.com/?kbid=903095

    After you're done, followed by compacting your folders manually while working * off * and do it often.

    Click Outlook Express at the top of the the folder tree so no folders are open. Then: File | Work offline (or double-click on work online in the status bar). File | Folder | Compact all folders. Don't touch anything until the compacting is completed.

    Disable analysis in your e-mail anti-virus program. It is a redundant layer of protection that devours the processors and causes a multitude of problems such as time-outs and account setting changes. Your up-to-date A / V program will continue to protect you sufficiently. For more information, see:
    http://www.oehelp.com/OETips.aspx#3

    And backup often.

    Hi Craig,.

    Thanks for posting your question in the Microsoft Community forums.

    I'm sorry to know that you are facing problems after installing Windows updates.

    Any Windows specific update which is the origin of the problem or you face the problem after installing updates? This is to check if the updates you receive are associated with hard devices.

    To view your history of update, follow these steps:
    a. open Windows Update by sliding into the right edge of the screen (or, if you are using a mouse, pointing to the corner bottom right of the screen, move the mouse upward), tapping or clicking on settings, tapping or clicking change PC settingsand then by typing or clicking on update and recovery.

    b. press or click view update history.

  • By creating a cloned connection, invite to what cluster and cluster datastore

    Hello

    I worked on this script to create a clone with some customization. All good here, but something basic to get a popupbox asking me to deploy to which cluster? and that DTX200 of cluster (and therefore the list of people for me) I can't understand how to do this?

    In the script I can code in hard the $cluster and $datastoreclustername but I would like a prompt for this

    This is the upper part of the script that I currently have are:

    Connect-VIServer "vcenter.domain"
    $sourceVM = Get-VM "test-replica" | Get-View 
    
    $agentTotal = 10
    $totalXPCount = (Get-VM -Name test* | Measure-Object).Count
    
    if($totalXPCount -lt $agentTotal){
        for($adt = $totalXPCount + 1; $adt -le $agentTotal; $adt++){
               
            $cloneName = "test1{0:0##}" -f ($adt+13)
            $cloneFolder = $sourceVM.parent
            $cluster = Read-Host "Enter vCenter Cluster: "
            #$cluster = "cluster-3"
            $datastoreclustername = "cluster-3-bronze"
    
             foreach ($vm in $cloneName){
     
            $cloneSpec = new-object Vmware.Vim.VirtualMachineCloneSpec
            $cloneSpec.Snapshot = $sourceVM.Snapshot.CurrentSnapshot
    
            $cloneSpec.Location = new-object Vmware.Vim.VirtualMachineRelocateSpec
            $cloneSpec.Location.DiskMoveType = [Vmware.Vim.VirtualMachineRelocateDiskMoveOptions]::createNewChildDiskBacking
            $cloneSpec.Location.Host = (Get-Cluster -Name $cluster).MoRef
            $cloneSpec.Location.Datastore = (Get-DatastoreCluster -Name    $datastoreclustername).Extensiondata.MoRef
    

    Oh how can I get the fancy of the PowerCli colors?

    The following PowerCLI code will give you a list of cluster names which you can choose one by the number:

    $Cluster = Get-Cluster
    $CLuster |
    ForEach-Object -begin {$i = 0} -process {
      "$i. $($Cluster[$i].Name)"
      $i++
    }
    $ClusterNumber = Read-Host -Prompt "Enter cluster number"
    $Cluster[$ClusterNumber]
    

    You can use the same technique for data warehouses.

  • How can a datastore iscsi never mounted/dismantled on a host?

    Hello

    I wonder how do I know if a store of data never mounted/dismounted iscsi on a host?

    Here are the steps and I got in trouble.

    1. Add iscsi target static to the host.

    2 rescan HBAs

    3. If the data store is connected recently vSphere will rise this data store. If not and the data store was dismantled to the host of the last connection and then I manually mount (mountVmfsVolume) this data store.

    If I manually mount a data store that involves automatic Assembly of vSphere so it will be occurs "InvalidState Exception" on statement "mountVmfsVolume" from the CROWD. The exception message is "the operation is not allowed in the current state.

    How can I know if the data store will be auto-monté and avoid this exception of CROWD? Is any information that I can use before getting this data store manually?

    Hi, wood,

    read the following article.

    Disassembly of a LUN or detachment of a unit of data/warehouse of several 5.x/6.0 for VMware ESXi hosts (2004605)

    When the device is detached, it remains in a State not fitted even if the unit is represented (in other words, the detached state is persistent).

    To set the device online, the device must be fixed.

    If you want unit decommission definitely an ESXi host, manually remove the NAA to configuration of the host entries:

    So you can use command base for esxcli detached storage unit list to check if the host has upped this device earlier or not.

    When the device is presented at the start (or manually permanently removed from service before), it will not appear in the list.

    When the device with a VMFS was removed earlier and not permanently taken out of service, the naa.ID appears in the list.

    Kind regards

  • Shared the Datastore (iSCSI / LUN)

    Hello

    Here is my configuration:

    3 x HP DL380p

    2 x Netgear ReadyData without (21 to each)

    I installed on each server ESXi and vCenter running and working.

    What I want to do is to create a data store on each of the San via iSCSI so that all 3 hosts can access them, so that if a virtual computer fails it is lit by the next available host.

    So far I figured out how to add a NFS share to each of the hosts with the same data store but can't seem to do it with iSCSI.

    Can someone give me a break down of what I have to do?

  • ESXi 4.1, does not use the entire RAID 5 on Dell R810 datastore

    I installed ESXi 4.1 on a Dell R810.  I've raided the first two drives in a RAID 1 and installed ESXi.  The 4 remaining disks are in a RAID 5 for the main data store.  ESXi acknowledges that the RAID is 2.7 TB but will only create a.7 TB or 744,75 GB data store.

    I did the same thing on several Dell R710s without problem.  Someone at - it ideas?  I guess it's a driver issue, but I do not see updates to driver for 4.1 for Dell R810

    The maximum size of a 4.1 data store is 2 TB less 512bytes. If you want to see the entire data store, you will need to upgrade to ESXi 5
