• How can I get the number of disks for a virtual machine and PAHO are / s of a disc?

  Hi all

  I would like to know if there is a command that returns the number of disks having a virtual machine.

  and also if there is no command to obtain and change the number of the IOPS / disk s.

  Thanks in advance

  Carlos

  It will give you hard drives attached

  Get - VM | Hard drive

  
  

  It will give you count
  

  Get - vm | Select name, @{N = "TotalHDD"; E={($_ | (Get-harddisk).count}}

  
  

  It is possible to retrieve the number of the IOPS / disk s, but what do you mean by editing.
  

• Move ROW with dynamic disk to another virtual machine

  Hello

  I'm in a situation where I have to leave my RDM Win2003 VM to win2008, but the complexity and multiple physical RDMs here make only dynamic partition (RDM1 1.5 TB, RDM2 1.5 TB, is drive G RDM3 1 TB 4 TB),

  Now my question is if I can move this partition of G (which includes 3 disks RDM) again an another VM (win2008)

  Thanks, SD

  Hello

  This does not resemble a specific question VMware.  On the contrary, seems like a question of Microsoft Windows.  Just make sure the hosts on which the virtual machine of 2008 runs can see the same ROW and follow this procedure to remove dynamic disks of the virtual machine of 2003 and add them to the virtual machine of 2008.

  Move disks to another computer

  All the best,

• Copy of the data of the disk of the virtual machine on a Local disk is too slow

  We have recently implemented vMware view.   We vSphere 5.5 and 5.2 and made Desktop visualization server.

  We have SAN as HP 3Par and Esxi hosts are HP ProLiant DL380p Gen8

  Now all trying to copy the data from the disk of the virtual machine disk of the local computer are too slow. But if we are writing data from Local disk on the disk of the virtual machine is normal. And copying data between the two virtual machine disk is also fast.

  Thanks in advance for your help

  Dear all,

  Thanks for your help.

  We have analyzed the issue in 360 degrees, and we also examined your entries. Finally, we found the problem. It was that a defective fiber link has been creating the problem.

  We have recently implemented vMware and this flaw in fiber can also happened during this period. That's why we thought it may be because of vmware.

  Thanks again for your help

• delete a virtual disk of the virtual machine of broken storage

  I have a virtual disk to a virtual machine on a broken iSCSI storage,

  now I can not remove the disc from the virtual machine.

  ESX 4.1 does not see the now broken iSCSI storage.

  See attach.

  Remove the virtual machine from the inventory and edit VMX manually deleting the reference to this disk. After that, add the machine virtual back again for the inventory.

• Maximum number of virtual disk for a virtual machine in vSphere 4.1

  I read the maximum record rate and see that the maximum number of virtual disk is 16 for FT.

  I have the same document I seem not to be able to see the number max of virtual disk that can be taken in charge for a virtual machine.

  The number will be the same as the number of LUNS per host which is 256?  I know the max is for the host, but that be will come the number of Director to the total number of virtual disk that can be supported in the virtual machine?

  In fact, in a logic unit number, we can have more than one data store that can be mapped to a virtual disk.

  I'm confused.

  Thank you and have a nice week,

  Anthony.

  If I am not mistaken, you can attach up to 60 virtual disks to a virtual machine. 15 for each of the 4 virtual SCSI controllers.

• Connect physical hard disks to the virtual machine (and leave the data intact)

  Hello

  I'm looking to virtualize a SOHO headless server, that I use mainly for secure file storage.

  Currently, the system runs Linux installed on a small disc and has two drives 1.5 TB, used exclusively for data, in a cluster of ZFS mirroring. (I use the ZFS-fuse Linux-based application).

  I want virtualization for two reasons. One is to make administration easier and safer - avoid having to connect a keyboard and the physical monitor to the box from time to time. The other is that the machine is a bit more powerful to handle the load, and I'm hoping to make it work on other, more challenging tasks.

  Now, there is a catch. These discs are as highly important. I mean the data on them. What I need is to convert the current Linux system to a virtual machine, or re - install Linux on a virtual machine (don't like that), then connect the physical disks to the virtual machine as if they were actually connected.

  I certainly don't want to vmware touches those disks somehow.

  I've read the documentation, but I'm a noob when it comes to server virtualization and system engineering and don't quite understand if this is possible or not. These discs are not a SAN, they are physically connected to the server, I want to install vSphere on. (Of course, I'll log out when I run the setup of vSphere. But I need plug them again later, and they need to be sure that vmware will leave them alone and pass them to the virtual machine transparent.)

  Sigmoid wrote:

  Oh yes, the cluster mirrored ZFS. It is essentially a software RAID type thingie.

  http://en.Wikipedia.org/wiki/ZFS

  A material, or the point of view of virtualization, it appears two hard drives with a single huge partition on each that is not transparent to anyone, except the implementation of ZFS.

  OK, means that you can break the RAID, connect the drives to different host and configure RAID once again, right?

  Let's do it this way

  1. We will need a disc player more for VM, cause on flash, we install ESXi
  2. I will share ZFS :-), all you need to do with that before you install ESXi
  3. make the BACKUP!
  4. Disconnect the data host drives
  5. install ESXi 4.1 U1 free version on flash
  6. Download the site VMware vSphere client
  7. Connect the VM disk to ESXi
  8. customer help create the virtual machine and install the OS on it
  9. stop the virtual machine and esxi
  10. connect DATA drives to the ESXi host
  11. begin to ESXi
  12. See how to add RDM on youtube, after client use, change first hardware VM--> add a new hard disk--> choose Raw Device Mapping--> (physical or virtual) mode--> store it with folder VM - FACT
  13. Start the virtual machine, now your VM should see both drives, with good data course :-)

  I have just made this procedure (add ROW with data in Linux VM) on ubuntu VM, works well

  See you soon

• How to make a visible USB hard disk for a virtual machine on ESXI 4.1?

  Hi all

  As I am new to the world of vmware ESXI, I always make mistakes or I don't undertand all therefore be complete :-).

  So I have a HP Proliant ML 350 G6 Server installed with ESXI 4.1 and I want to connect a USB hard disk to a virtual machine (SBS 2K 8). Currently, the virtual machine is not able to see the hard drive.

  I already add a USB controller to the virtual machine, but my USB HARD drive is still not visible to my virtual machine.

  Can you help on that?

  Thank you

  Michael

  Next, add a USB device to the virtual computer (in the change settings tab), there are different things, USB controller and USB devices. Sometimes, you may have to restart the virtual machine.

• Can I convert a server disk to a virtual machine?

  I have a number of OS X 10.5 servers running on hardware that is incredibly underused.  Since the Fusion 3 supports running OS X Server virtualized, is it possible to convert a live server disk to a virtual machine to the BootCamp to VM? I could run all 5 of my server on a single Xserve systems. I dug around, but everything points to a new facility to achieve this.

  Thank you

  Tim

  Yes, it is possible to convert physical machines to Mac OS X Server VM. I've posted instructions on how to do this in the following thread: Re: Snow Leopard Server VM existing?

  In your case, the only thing that needs to change is the version of the OS - pick instead of 10.6 10.5. I tried this with one of my machines so far, I would be interested to comment on the question of whether instructions to work for you. I'll probably convert this post into a document at some point...

  I also thought the ability to hire only the OS X physical disk partitions without copying the data (like Fusion for Boot Camp). However, Fusion currently only supported the MBR partition tables to access raw partitions, and most Macs are partitioned GPT (or hybrid MBR + TPG). You can try to use Library/Application Support/VMware Fusion/vmware-rawdiskCreator to see if it recognizes the OS X partitions. If so, you should be able to create a virtual disk that references the partitions and boot from it as you would for a machine virtual Boot Camp.

  It is also possible to use a physical disk full (instead of individual partitions), but you would need to have partitions not mounted before using virtual machines that reference the physical disks. If you are interested in, there is a link in this thread as well.

• How to increase disk for/tmp space in virtual machine?

  People,

  Hello. I use VM Player 3. My host computer is Windows 7 and VM is Oracle Linux 5.10.

  When I copy a virtual machine host machine (1.2 GB) file, the error message appears:

  "Unable to write file in Virtual Machine.Aborting the copy file operation."

  To be able to copy the file into the virtual machine, it takes about 2 GB of disk space free for the folder/tmp.

  I cleaned all the files in the directory/tmp which is now empty. After that, I ran the cammand:

  $df h/tmp

  Its output:

  File system: / dev/map/VolGroup00-LogVol00

  Dimensions: 95G

  Used: 90G

  Available: 48 M

  : Use 100%

  Mounted on: /.

  As you see above, it has only 48 M free disk space, the file size is 1.2 GB to copy.

  My question is:

  How to increase disk space for "available: 48" to the directory/tmp in VM Oracle Linux 5.1 so that can copy the file?

  Thanks in advance.

  The log files are rotated. You have only the *.log files, but the former obsolete log files too. Are named name.log001 name.log002 and so on.

  Check out some of the files you found the log files and remove turned the oldest logs first. Once you have deleted a couple check if cela disk space savings.

  In theory, you can remove all of the log files, but be careful that no server component runs when you do that. Otherwise the logging stops until you stop and restart the component. If you are not sure if something is running, start with swivelled out newspapers.

• VM pre-allocated low disk space

  Hello

  I run 3 VM (VMware Workstation), each has its own hard drive. When I installed these machines I have previously assigned space on the assumption (false!) that the virtual machine would not grow. I'm now so low space than a machine cannot start, and as much as I know I can't shrink a pre-allocated VM?

  First of all, could someone tell me what increses in fact the size of the file and as a percentage of the available disk space how much I have to leave in the future of the room?

  Secondly, how can I get out of this situation? As a temporary measure, I could copy the virtual machine to a drive with more space, but I need to get it back on the original disc later, is it possible to resize a pre-allocated machine?

  I think that, in the light of the foregoing, you can guess that I am a user not a computer scientist.

  Thanks for your help... Marcus

  the command, we suggest you will create a clone of the current state.
  The size of the resulting vmdk would be slightly larger than the netto-data on the original disc.

  So if the Explorer inside the guest who would claim the 270 130 GB Gb serve the vmdk resulting could be as small as 140 GB.
  The exact size of the vmdk resulting isn't exactly predictable, but it is maybe much smaller than the original vmdk.

  The performance problem with the instant results from the mere fact that VMware should then read several files.
  It goes like this...

  GuestOS wants to read sector 100.00 on the disk = the first VMware audits if 100,000 area is inside the snapshot 2.
  If there is good - VMware check if this sector is inside snapshot1. If so very well - if not - VMware must also read the basedisk to find 100,000 sector

  This means that playback has several steps more than if you would use a vmdk préallouée without clichés.

  I generally recommend to use type growth basedisks if you know you want to make heavy use of snapshots

• Disks of the virtual machine consolidation is necessary - vCenter 5.1 U1 + ESXi 5.1 + VDP 5.8.0

  Hello

  I am facing problem as many other people do, when snapshot is deleted, the delta files are still there and warning message "consolidation of disks of virtual machines is necessary" is shown on the virtual machine.

  It happened only few but try to find the root cause. He arrived only on virtual machine located on ESXi 5.1 build 799733 which is located in the task of the WTP 5.8.0 backup.

  Is this snapshot problem, a bug in the version of ESXi?

  Unable to find the release notes, where this is documented as bug.

  Thank you

  Finally, I found a reason, therefore, for other users... ESXi 5.1 build 799733 has a bug that is resolved in the update 1 and higher and is connected to the suspended snapshots created by POS, that is why are there so many discs of delta.

  ESXi 5.1 Update 1 Release Notes

  • When the slowdown of snapshot fails the redo logs are not consolidated
    • When you try to take a snapshot of the suspension of a virtual machine, if the snapshot operation fails near the end of its realization, recovery logs created as part of the snapshot are not consolidated. Recovery logs can consume a lot of space to store data.
    • This issue is fixed in this version. If the snapshot suspended operation fails, the redo log files are consolidated.

• Cannot open the hard file. One of the disks in this virtual machine is already in use by a virtual machine or a snapshot

  Hi all

  Tried my level best to solve, but still the same problem persists. . Lck tried but as soon close VMware workstation, it disappears. This problem starts when yesterday instead of powering down, suspended. The next resume when it gives captioned error. Tried creating new virtual machine using an existing vmdk file but my mainly all the data disappeared. Now I want to resume the suspended state. Kindly help on the same. Thank you

  OK, we will first focus on the first virtual disk (System) on the D: drive which has enogh of disk space to create a clone.

  The "Windows Server 2003 Enterprise Edition.vmdk" dated from 19/07/13 is probably exactly what we need, and if it has approximately the same size of file than current/changing, then you can replace the one changed with it. Once restored, proceed as follows (with VMware Workstation closed):

  from the command line run:

  cd /d "C:\Program Files (x86)\VMware\VMware Workstation"
  cd /d D:\win2k3
  md Clone
  C:vmware-vdiskmanager.exe -r "Windows Server 2003 Enterprise Edition-000002.vmdk" -t 0 "Clone\Windows Server 2003 Enterprise Edition.vmdk"
  

  Once the cloning done so, create a subfolder "Backup" and move all over existing files (as a backup). Copy the .vmx file and .vmxf the subdirectory "Backup" in the D:\win2k3 folder, then do the same with the file hard cloned since the 'Clone' subdirectory, so that you end up with the following files:

  Windows Server 2003 Enterprise Edition.vmx

  Windows Server 2003 Enterprise Edition.vmxf

  Windows Server 2003 Enterprise Edition.vmdk

  Before you can try to start the virtual machine, you must edit the .vmx file and replace

  scsi0:0. FileName = "Windows Server 2003 Enterprise Edition - 000002.vmdk"

  with

  scsi0:0. FileName = "Windows Server 2003 Enterprise Edition.vmdk"

  Please do the above and report. If you have any questions please ask.

• Problem with ESXi 4.0 with Allocation of disk on a virtual computer

  Hello Experts

  Physical server:

  HP DL 380 2 proc Intel Xeon 4 GB RAM

  6 x 146 GB HDD (with RAID5) = > total available capacity 650 GB

  Problem:

  I am creating a VM with OS = DEBIAN6

  When I allocate 300 GB HARD drive for the virtual machine, it gives me just 256GB.

  I don't understand the reason.

  I read that this could be linked to the BLOCK SIZE.

  What is your opinion? If so, how can I change the block size?

  Thanks in advance

  Options of your choice after.

  Block size of 1 MB = Max VMDK 256 GB

  2MB block size = Max VMDK 512 GB

  4MB block size = Max VMDK 1024 GB

  Block size of 8MB = Max VMDK 2048 GB

  First calculation of disk space when set up 2 MB to 512 GB.

  Hi Sergio,

  Here is an example of code (the input parameter is type virtual machine vm ):

  var devices = vm.config.hardware.device;
  for each (controller in devices) {
    var is_scsi = controller instanceof VcVirtualBusLogicController || controller instanceof VcVirtualLsiLogicController
         || controller instanceof VcParaVirtualSCSIController || controller instanceof VcVirtualLsiLogicSASController;
    if (!is_scsi) {
      continue;
    }
    var controller_label = controller.deviceInfo.label;
    System.log("SCSI controller found: " + controller_label);
    for each (device in devices) {
      if (device.controllerKey == controller.key) {
        var scsi_id = controller.busNumber + ":" + device.unitNumber;
        System.log("    device found:  '" + device.deviceInfo.label + "'  'SCSI (" + scsi_id + ")'");
      }
    }
  }
  

  SCSI ID is a combination of the number of buses of the controller and unit of the device number.
