Vmfs only store data on two physical disks on ESXi host?

• several stores data on the same disks

  It's so strange. I can't create several stores data on the same drive. I have a 2 TB plugged on my server (motherboard) disk and after that I created my first store of data (100 GB), when I return to create another, that the drive isn't an option for me to create a new data store of. When I delete the data store, the drive comes as an option to create a new data store of. WTF?

  of http://pubs.vmware.com/vsphere-esx-4-1/wwhelp/wwhimpl/js/html/wwhelp.htm#href=fc_san_config/c_making_lun_decisions.html

  A logic unit number must contain only a single VMFS data store.

  I guess the reason for this is a SCSI reservation. Even if this has been significantly reduced in 4.x it is still necessary for some operations. Each SCSI reservation - even if this is necessary for an operation on a datastore - locks the entire disk and could therefore cause problems on other stores of data on the same drive.

• Store data with the VM disks?

  I read a few whitepapers that suggest a maximum number of VM are run by LUN.  That being said, the recommendation would be to "drive with the virtual machine shop", or on a separate data store?  In what senario would you do one of the two?

  If you have group single disc less than 2 TB total in most cases there is no need to make separate data warehouses.

• Save the number of the Virtual Machine: expand the size of the virtual disk of Guest OS affect the physical disk on the host operating system files?

  People,

  Hello. I use 3 Player VM and Guest OS Windows Server 2003. The host OS is Windows 7. I need to increase the size of the VM disk, so who can install several systems in the guest OS. If something bad happens during the expansion of the size of the virtual disk, the guest operating system and its Applications will not work. Thus, before expanding the size of the virtual disk, I need to back up the virtual machine hard disk external.

  I have check the disk hard host operating system Windows 7, the path is C:\VirtualMachine\WindowsServer2003\... When I get to the top of the virtual machine on the external hard drive, simply select the 'VirtualMachine' folder and save automatically. I have 3 questions as follows:

  First of all, if something bad happens during the expansion of the size of the virtual disk, the guest operating system and its Applications do not work. Can I just delete the folder 'VirtualMachine' in the host operating system?

  Secondly, the problem of the first question does not affect files in the physical hard disk to host operating system?

  Third, if something wrong happens during expand the size of the virtual disk of OS guest, I simply delete the folder 'VirtualMachine' in the host operating system and load the original 'VirtualMachine' from the external hard drive in the host operating system. Works correctly as long as one is the Virtual Machine before Stude the virtual disk size?

  Thank you.

  Yes.

  That's right, as long as you have not added and other virtual disks of different folders on the host of the virtual machine, you can probably did not.

  After developing the size of the virtual disk, you must also change the size of the partition in the guest operating system.

• Why not place the Oracle data files on local disks

  Hi, I want to ask a fundamental question.
  
  Almost any Oracle installation I've seen, data files have been placed on Mount points, disk etc..
  
  Is there a reason for this? Why no one does place for local disks oracle data files? I couldn't find the answer on the installation guide
  
  I ask this because I will install oracle (10g) on vmware and trying to decide whether to put data on the vmdk (virtual computer local disk) files...
  Is - this recommended? If not, why it is recommended to put data files to a disc of fixation for point/external etc..
  
  
  Thanks in advance

  Hello

  People store data files on separate disks
  (1) bettter performance
  (2) the data can be in a centralized storage
  (3) if the OS crashes always files are safe
  (4) configurable with raid options
  (5) hot Swapping
  (6) easily can add additional storage

  Kind regards

• Fully connecting directly attached data warehouses in a cluster of ESXi?

  I have deployed two identical 5.1 ESXi hosts (servers Dell PowerEdge r720xd) each to 5,46 with storage to direct connection. They are both currently enrolled in our vCenter Server 5.1 and participate in a HA cluster. Their respective databases are also members of a group of data store.

  Each host is connected to its own data store, but not the other host data store. This effectively disables most of the HA/DTS features, and connection status of host for each data store is marked with a warning for missing connections. We have desire of VM migration and load balancing between the two hosts and the warehouses of data to be as homogeneous and transparent as possible.

  My question is simple: what is the most practical and effective way to establish the necessary connections to reach a State fully connected to hosts and data warehouses?

  Hello

  in this case you need something like a virtual appliance that uses your local storage to make it a shared storage. Your hosts can then access the storage via iSCSI/NFS. At the end of the day, you will have the space of a single node left (CT ~ 5.46), because the device (s) will reflect your data for more security against failure of the host.

  The easiest way would probably be the vSphere Storage Appliance

  But there are also other solutions as a virtual of DataCore and HP StoreVirtual VSA facility.

• If I put in place an openfiler VM as a data store iSCSI & vmfs on two ESXi hosts, both ESXi hosts can access two data warehouses?

  If I put in place an openfiler VM as a data store iSCSI & vmfs on two ESXi hosts, both ESXi hosts can access two data warehouses?

  The reason why I ask, is that I have two hosts ESXi ESXi 4 running.  I do my backups with ghettoVCB, which I modified to create thin backups on one of the drives the.  I then wput them to the server, which causes them to become thick.  Directly targets the backup in a vmfs iSCSI on the server in the face shop.  It would save a step and the vmdk backup should remain thin.

  Thank you!

  The short answer is Yes. If you allow the ESX servers to see the LUN. This setting is configured to the Openfiler.

• Store data to run out of disk space...

  Hello world

  Hope you can help with that... My server is running more disk space. I have an old server of ESX3.5i. She has 280 GB disk 3 space hosting servers. But the allocation of disk space total for this 3 virtual servers are about 90 GB. So the ESXi server should have at least 180GB available. However, I just checked and the system told me that the 280 GB data store has only 1.93 GB left...

  May I ask why this happens? And how do the clean up?

  Thank you very much for your help!

  ... for those who will be always stay and eatup storage?

  VMware will not delete the VM unless requested by the user. When you right click on a virtual machine in the inventory, you have two options "Remove from Inventory" (which is what probably did you) and "remove disc", which will remove the files of the virtual machine.

  What you can do if the virtual machine has already been withdrawn from inventory is just remove it from the data store or right-click on the VMX file and select 'Add to inventory' and then use the option "remove disc".

• Help with report VM (name MemoryMB NumCPU, data store, total size of the disk)

  I currently have a script (listed below) to the CR of query for each virtual computer and their allocated disks. The problem with the script is that when he meets a VM with disks on several data only stores the first data store is listed in the report. However, the total size of the disk is correct.

  Any ideas to fix this?

  $datastoreExp = @{N = "Datastore"; E = {($_ | get-datastore | select-object-1 premier).} Name}}

  $diskSizeExp = @{N = "Total disk"; E = {($_ | get-harddisk | mesure-objet-propriété CapacityKB-somme).} Sum}}

  Get - vm | Select the name MemoryMB NUmCPU, $datastoreExp, $diskSizeExp | Sort - property datastore, "Total disc | Export-Csv C:\Scripts\Reports\chargeback.csv

  I thought that was what you wanted, judging by your examples.

  In any case, no problem, the following should do the trick.

  
  $dsRegEx = [regex]"\[(\w+)\]"
  $report = @()
  get-vm | % {
       $vm = $_
      $vm.HardDisks | %{
            $row = "" | Select Name,MemoryMB,NUmCPU, Datastore, "Total Disk (Gb)"
            $row.Name = $vm.Name
            $row.MemoryMb = $vm.MemoryMb
            $row.NumCpu = $vm.NumCpu
            $row.Datastore = $dsRegEx.Match($_.Filename).Groups[1].Value
            $row.{Total Disk (Gb)} = "{0:N}" -f ($_.CapacityKB / 1Mb)
            $report += $row
       }
  }
  $report | sort -property Name, datastore,"Total Disk" |Export-Csv "C:\chargeback.csv" -noTypeInformation
  

  Since there are sometimes problems with the display of the hooks I have attached the script.

• PERC 710 add physical disks for RAID 5 virtual disk and keep data

  I think to set up a physical disk 4 RAID 5 array on my new PowerEdge T320.  That should give me enough space to last long.  I have two empty slots of HD.  If I need more space, later, I'll be able to add one or two additional physical disks without losing the data already on the virtual disk?  If so, how?  I don't see a way to do this in the manual of Perc 710.

  Thank you

  Andrew

  Yes, it is "doable" later.  This can be done in the PERC BIOS, but it can be done in OMSA (OpenManage Server Administrator) within the OS.

  One thing to keep in mind is the limit of 2 TB "floppy" Windows on BIOS systems compatible.  If you plan to 4x4TB disks in a RAID 10, that TB ~ 8 'disc' will be converted to the GPT and BIOS UEFI boot mode value.

• AGAIN starts after only one physical disk has several partitions makes no sense to the production oracle database?

  Dear Experts,

  Don't + REDO1 diskgroup have only one physical disk has several partitions makes no sense to the production oracle database?

  For example

  • + Diskgroup Redo1 have 2 50 GB disks (fact these 2 discs are the same physical disk partitions OR these should be separate disk as recommended approach)?
  • + Diskgroup Redo1 have 2 drives of capacity 50 GB (for RAID 1 + 0)
  • + Diskgroup Redo2 have 2 50 GB disks
  • + Diskgroup Redo2 have 2 drives of capacity 50 GB (for RAID 1 + 0 )

  Hello

  Partitioning your disks for ASM configuration as 'A' might make sense. If you lose one disk, you have the discs to another.

  'B' totally make sense if you have lost the disc that you have lost all group ASM and you need to change this with something like 'C '.

  But obviously you need redundancy ASM configured appropriately.

  

  Kind regards

• 3 physical disks in 1 TB in RAID 5 with only its 1 TB usable space incorrectly? Using a Dell PERC 6 / i controller.

  We have a server Dell PowerEdge with a PERC 6 / i controller. There are three physical disks for 1 TB. I created a RAID 5 array, but it seems that there is only 1 TB of usable space after you initialize the virtual disk RAID 5.

  What is wrong? I Googled what should be the size, and I think we should not 1 TB, 2 TB of usable space?

  Too bad. It looks like the physical disks are 500 GB in size, which makes sense.

• Reference Dell MD3000i and degraded physical disk channel

  In this case recovery guru say "you must contact your technical support representative to correct this defect. Do NOT try to fix this problem yourself. So, how we can receive technical support recommendations and try to repair this failure?

  If you need more details, we can put any storage array profile output.

  Hello UtkinE,

  Yes, you will need to stop all iSCSI traffic so that you can update the NVSRAM.  With the timeout error you get all came from controller 1 & he had only discs 1 & 5.  The current version of NVSRAM you version 4 and the last one which is for the MD3000i is version 13.  With who have older firmware it was improvements to correct your problem in the latest versions of firmware.  I also had one of our analysts will confirm as well just to make sure that it is the best fix for your problem.

• Expand a virtual disk with new physical disks?

  Hello people,

  Pleas in law not to shoot me to ask what I fear it may have already answered somewhere and my research is poor and as still not turned up the answer.

  I'm relatively new to VMware, previous job was especially MS Hyper-V and is always to some extent.

  Hower to the point in question, I have a single host (VMware ESXi 5.0.0) with a single server VMware 2008R2 on her guest and the C: drive is quickly running out of space. The existing, aligned hard disk virtual hard disk has 10 GB free to extend the ramdisk with.

  Therefore, my thoughts are I might add an another one or two new physical disks and add them to the data store that is aligned with the virtual C:\drive to the comment server, I would then be able to extend the exisitng C:\ virtual hard disk with the new ability to drive two new physical drives added?

  Hope this sense makses, hoing it's okay and I get out of jail!

  Thank you very much

  Hello

  Please see this link because it deals with the procedure to enlarge a vmdk and extend partition in comments

  First enlarge the data store after the addition of physical drives. Select the data store, properties, increase and the LUN detected.

  Then use the vmkfstools as explained in the video to develop

• 12.04.01 Ubuntu x 86-putting in place a virtual Windows XP machine to access the physical disk

  Dear community,

  I'm new to VMware Workstation, but progressed in computer science.

  At first, I want to give you a brief introduction of my system and my goal.

  HP ProBook 6550 b (System with Intel Core i5 processor Intel-based)

  The HARD drive access mode: S - ATA AHCI

  Operating systems: Windows 7, Ubuntu 12.04 x 86, Ubuntu 12.04 x 64

  Boot Manager: GRUB2

  VMware Workstation (trial period) to 9.01 Linux x 86

  Goal: install MS Windows XP Professional with physical disk access several partitions on the hard drive local

  The installation of VMware Workstation 9.01 on my system Ubuntu 12.04 x 86 worked perfectly, without any error. Large.

  I was able to set up and run a Windows XP VM standard by creating a new virtual disk , following the Nice Wizard.

  It was just to test, but just after I tried to configure the same OS as a virtual machine using a physical disk (for advanced users) to directly access a local hard drive.

  Also, I selected "BusLogic (recommended)" on the choice of type of I/O controller.

  As a device, I chose the HARD internal laptop drive and used two individual partitions (the real partitions on my HARD drive I wanted access within the virtual machine).

  These partitions have been preformatted with NTFS (and not have been mounted in my Ubuntu).

  However, I was not sure if Windows XP has been will be installed on one of these partitions.

  The turn on/off the virtual machine to install the OS, I got the message following (msg1):

  "You are using a SCSI drive. Performance of dual-boot SCSI physical drives are poor. The installed operating system could not start correctly in the virtual machine. However, the physical SCSI disks work normally so exclusively in the virtual machine. »

  Just after the message following (msg2):

  "If you dual-boot a native Windows installation, problems can occur when attempting to start your system in VMware Workstation." For more information, see "http://vmware.com/info?id=128". "
  Click OK to continue, Cancel to power off.

  And finally this (msg3):

  «An error has occurred causing a virtual CPU go into the stop State.» If this anomaly had occurred outside of a virtual machine, it would have caused the physical machine restart. The stop State are accessible by properly configuring the virtual machine, a bug in the guest operating system or a problem in VMware Workstation.
  Click OK to restart the virtual machine or Cancel to turn off the virtual machine. »

  I cannot explain the last error message and don't know what to do.

  After specifying msg2, I found information about possible problems in dual-boot environments, caused by different drivers for the IDE controller.

  So I tried to change the access mode to S - ATA AHCI HARD drive to S - ATA IDE in the BIOS to solve the problem.

  Unfortunately, I have had no success on this operation, because the error message appeared again, once I restarted the VM.

  Sorry, but I have no idea what goes wrong.

  In fact, I don't know what VMware workstation wants to do, when you install the system on a disc/physical partition to have direct access to the local hard disk.

  Because I don't see even the first screen of Windows Setup, there must be something wrong.

  Underlying product system issues and if it's a primary or logical partition?

  Need a complete unformated HDD?

  Only selected partitions are accessible within the virtual machine?

  Is the system installed itself on the selected partitions?

  Maybe some experienced users can help.

  Your help is welcome!

  Thank you.

  First I use a raw disk to install Windows XP from a virtual machine, but if I had an existing installation, I would add the partition as a raw to be executed with a VM disk.

  Here's what I'd do...  Install Windows XP to a normal file based virtual machine, and then add a second disk as a raw disk with the partitions you want to join.  That's assuming that you really need not where what to start Windows XP natively and the physical partitions that access are used for data.  Also if need be add the raw disk as IDE.
