• Is it possible to use GPFS or another build is a SAN storage shared for multiple ESX and ESXi hosts?

  We have a license GPFS and SAN storage. I am trying to create a storage shared for multiple ESX and ESXi hosts share existing virtual machines. We tried once NFS, it of a little slow and consume too much bandwidth LAN.

  Anyone can help answer? Thank you very much in advance!

  It depends on your storage space.

  You must connect all hosts to the same San, then follow the configuration guide of ESXi and specific documentation for your storage space (for sharing LUNS on multiple hosts).

  I suspect that you posted your question to the wrong thread

  This requires only a minor change to the script above actually.

  Something like that

  $groupName = "group"$accountName = "user"$accountPswd = "password"$accountDescription = "A user"
  
  $esxlist = Get-VMHostforeach($esx in $esxlist){    Connect-VIServer -Server $esx -User root -Password "password"
  
      Try {      Get-VMHostAccount -Id $groupName -Group -ErrorAction Stop | Out-Null    }    Catch {      New-VMHostAccount -Id $groupName -GroupAccount | Out-Null    }
  
      $rootFolder = Get-Folder -Name ha-folder-root    Try{        $account = Get-VMHostAccount -Id $accountName -ErrorAction Stop |        Set-VMHostAccount -Password $accountPswd -Description $accountDescription -AssignGroups $groupName    }    Catch{        $account = New-VMHostAccount -Id $accountName -Password $accountPswd -Description $accountDescription -UserAccount -GrantShellAccess -AssignGroups $groupName    }

• What is the interval of time between the virtual machine Linux and ESXi host synchronization?

  I have ESX5.0 with a centos6 installed on this linux virtual machine.

  After the installation of vmware for Linux virtual machine tools, I activated the time synchronization between the virtual machine linux and ESXi host through vmware-toolbox-cmd.

  I wonder what is the interval of time between the virtual machine linux and ESXi host synchronization? If I quickly time OS system, when the OS system time will sync back to the ESXi host?

  According to http://www.vmware.com/files/pdf/techpaper/Timekeeping-In-VirtualMachines.pdf:

  By default, the demon checks the guest only once per minute operating system clock.

  However, depending on whether the guest is behind or in front of the result is different. So, please read the section "periodic synchronization" (at least) in the document mentioned above.

• Move a virtual machine to turn off between two hosts, shared storage

  Dear Experts,

  Please guide me for the next case. There are two hosts of Esxi, host 1 is Esxi 4.0 and host 2 is Esxi 4.1. There are store data SAN storage that is visible to both hosts.

  I watched solard winds VM monitor utility that hosting 2 consumes 90% of the memory while its processor is ok. On host 1 is normal. So, I want to spend only a few VM of to host 1. So please correct me if what I think are OK. I will turn off the virtual machine to be moved from host 2. Then I it will remove host 2 inventory. Then on host 1, I'll go to the data store in the folder that VM and do a right click on the file 'say add to the inventory' and now I'm going to see this virtual machine in the inventory of the host list, just turn on and everything is perfect, is this correct?

  Second question on the same hosts, there are a few other data stores that are visible to a host. As if this is the case there is a virtual machine on a data store that is visible to host 2 and I want to spend this VM to host 1 to reduce load on host 2. How to move this virtual machine because this data store is not visible to host 1? Will I have to copy this VM files in a data store that is visible to host 1? If YES then what real required to copy files?

  Kindly help me.

  Kind regards

  From your description I m assuming that you use not vCenter to manage your hosts, correct?

  If you have a store of data shared between two hosts you can do the steps you descripte (power off, remove the inventory etc.).

  For your second case there are several ways, it depends on where you want to place the virtual machine in the future. Wouldn't be on the shared data store that already exists or can in the local data store on the other host? Or is there an option to also display the current data store to host 1?

  If you want to copy the VM files copy the whole folder of it.

  Kind regards

• Update for vsphere client and ESXi host, now getting errors

  Did a upgrade for my client vsphere, VMware-viclient-all - 6.0.0 - 3016447.exe file name

  Now I cannot view comments consoles, cannot add new guest OS (option is grayed out), and I get an error when the Client program starts (see first image)

  

  Here is the error when I try to view the console to the guest operating system. Can I use Remote Desktop connection to connect to the guest operating system (R2 for Windows Server 2012)

  

  Here is the version information

  

  Also improved the host system of the ESXi server to update to U1 using the VMware-VMvisor-Installer - 6.0.0.update01 - 3029758.x86_64.iso

  VMWare Tools never seems to complete the installation for the guest operating system.

  What can I do now?

  Client runs on a desktop computer Windows 7 Pro with 24 GB of RAM.

  ESXi is a server Dell Poweredge T110-2 with 32 GB of RAM

  I ran into the same issue and Re: VMware-viclient-all - 6.0.0 - 3016447.exe broke Console hosts 6.0 ESXi and ESXi 5.5 fixed it for me.

• Best practices for backup of vCenter device and ESXi hosts?

  Hello

  I have a new VMware environment based on 5.5 ESXi and vCenter Server Appliance. A few questions:

  • What is the best practice to perform the backup of the vCenter Server Appliance? I set up the camera with the embedded SQL Express database.
  • It's recommended to backup the ESXi host or is it easier to any re - install failure?

  Best regards

  Hello

  You can use VMware VDP to backup your device of vCenter. It is included in essentials, standard, enterprise, and enterprise as well as licenses.

  I won't have backups of ESXi servers. Restore the backup would take more time that the deployment of a new ESXi.Only thing, you may want to consider is to enable logging remotely, so you can see why the hosts failed.

• While add ESXi 6 existing hosts, vcenter server 5 std and esxi host 6 cann't add to AD

  Hello

  Greetings. !

  We have seen vCloude 5 Enterprise edition and vCenter Server Standard 5.5

  at the moment all my existing hosts ESXi 5.1 are managing through vCenter Server Standard 5, now recently we buy vCloude 6 Enterprise edition

  (1) I found the following problems all add ESXi 6 hosts (VMware ESXi - 6.0.0 - Update1-3380124- HPE) to AD sales thru of sphere, it is read error.

  

  I have already set up network, DNS, make sure firewall ports, Ping - are all OK.

  (2) Moreover, while trying to create new CD, add the cluster, then add hosts, is giving following error.

  

  I can add new Hosts 06 ESXi Existing vCenter Server 5.5 Standard or I have to buy updated additional license for vcenter server 5 std vcenter 6 standard / enterprise.

  Thanks in advance.

  ESXi 6 cannot be managed by vCenter 5.5 or earlier.

  He needs a same version or higher of vCenter server.

• RAID 1 hardware and ESXi - host not to see the virtual volume

  Please bear with me as I try to explain this issue in detail.

  I have an ESXi server.  He has a number of virtual machines and works.  This server has a LSI RAID controller and had a single hard drive connected to this controller.  I'm allergic to non redundant drives, so I added a second drive and, from BIOS boot from the RAID controller (before initialization of the server itself), I created the mirror and had the controller 'rebuild' the second disc, copy of an image of the first record on.  The controller did and displays a virtual (in BIOS) volume in a RAID 1 volume consisting of two physical disks.

  At this point, I expect from any server OS to see the single volume.  However, ESXi, at startup, see both drives hard physical (apparently without taking into account the supposed configuration of the controller, which is strange for me), and because they contain all the two identical copies of the ESXi installation, it purple-screens to complain about two identical UUID.  When I work around this error with the start command line option 'overrideDuplicateImageDetection', ESXi starts on one of the two disks.  vSphere shows the two disks and physical disks, mounted in the system.

  I'm relatively certain that the RAID card maintains the mirror.  The second disc is not part of a data store.  I would prefer ESXi see the mirror as the only logical volume so-called offer the RAID card, but I'll settle for ESXi, ignoring the second unit of disk in total.

  Any ideas?

  Thanks in advance for your help,

  H.

  Hello

  Some RAID controllers operating in RAID or RAID configuration. If no RAID is created, it will work like the generic SCSI cards and when a RAID is created then it will become an appropriate raid controllers. When you installed the ESXi map was probably operating in non RAID and later converted to a RAID controller mode. Please check the drivers loaded in the kernel of ESXi and if necessary, please include the RAID controller module and re build the boot image.

  Is it possible to give me the model number of the LSI RAID you use and the output of the inscription of the kernel module. I think that these dual-mode controllers were possible on older models of server, not sure that they are always available. I used to see this kind of problems with Linux in ancient times.

• RISKS associated with the absence of a SYS logs for newspapers and ESXi host newspapers vCenter Server

  What is the inherent risk to not configure a server of SYS logs. The sys normal newspapers configured in the data store have a maximum

  Locally stored logs to rotate and do not grow very big at all. I see no technical risk associated to this as filling a data store, etc.

• Migration and ESXi host PowerCLI license management

  Hi all

  I'm trying to understand if I want to do is possible using PowerCLI. I have 30 guests who need to have their permits assignment of keys changed/moved to a new key that was added to the environment. Is it possible to do this in PowerCLI?

  I got two keys with 16 cores of each key and I need to move my hosts specified for these new keys.

• vMotion between hosts 4 ESXi and ESXi 5

  I have a group of ESXi 4.x hosts connected to a vCenter Server 4.1.  I have an another 5.1 vCenter Server Management 5.1 hosts.  I want to move my hosts ESXi 4.1 in my 5.1 vCenter Server and upgrade to 5.1.

  Since vCenter 5.1 can manage ESXi 4.x and 5.1 hosts in the same cluster (KB VMware: upgrading vCenter Server 5.1 recommended)

  Could I add my 4.x hosts to vCenter 5.1 and put them in maintenance mode one by one and then upgrade?  I'd be able to vmotion the VMs between my 4.x and ESXi hosts 5.1?

  The goal is to reduce or hopefully elimate downtime for virtual machines.

  Thank you!

  You can get the upgrade with no interruption of service, if you can:

  (a) connect the storage 4.1 hosts FC 5.1 guests, so it is shared by all hosts

  or

  (b) your license allows you to storage vMotion the VMS to storage of 5.1 hosts

  The normal steps would be:

  -Disconnect the 4.1 hosts the vCenter 4.1

  -Connect the 5.1 vCenter

  -connect storage 4.1 for the 5.1 hosts or Storage vMotion the VMs on

  -vMotion the VMs to 5.1 hosts

  -upgrade the 4.1 hosts

  How to make a server esxi storage shared among other esxi servers

  You mean like we use openfile on a windows or linux box to provied storage lun with free space on them, like that on ESXi.

  TAT is then not possible. But still, you can create a virtual machine set up all the storage, installing openfile or starwind, from there, you can give access to shared another esxi storage.

  or

  Installing vcenter

  create the cluster

  every 2 or 3 esxi, who owns the local data store.

  now install vmware storage appliance - through you can make use of all the local data store to be shared across all the esxi.

• Local VMs of shared storage

  I have ESXi free license and create several virtual machines production in the local data store of ESXi, we complete installing vCenter server and add this host, proceed to the storage configuration and connect the ESXi too, we get the new vSphere license Enterprise liked.

  Someone would tell me how to move the virtual machines in the local data store of ESXi for shared storage, we need constantly to these machines, please?

  Best regards

  With the Enterprise Plus license, that you can live migrate virtual machine to a new storage. All you have to do to be able to use "Storage VMotion" is to ensure that the ESXi hosts have access to the shared storage. Take a look at for example http://www.yellow-bricks.com/2009/04/02/storage-vmotion-exploring-the-next-version-of-esxvcenter/ which has a screen shots, how it works.
