Complete zero to VMFS and vmdk using vmkfstool w

Hello community,

We are studying now "Zero detect' function on IBM SVC Thin provisioning.

SVC Thin provisioning Volume is unable to note removal of file on VMFS, so we need a way to fill blocks, we don't use on VMFS with zero.

Can we apply "vmkfstools w" command to VMFS?

We know that this command is vmdk, so that we can create or translate vmdk format to another.

but we do not know that this order may apply to VMFS or not.

We managed to run this command for vmdk(/vmfs/volumes/xxx/xxx.vmdk) and cannot run a VMFS (/ vmfs/volumes/xxx) on our environment.

Anyone know this specification?

afalk, vmkfstools you can only ask vmdk only.

For writing on a lun, can use DD.

  • VMFS and VMDK compatibility

    Hello

    I have a number of ESX 3.0.2 - Update1 host I do fresh installs of ESXi 4.1 on. The 3.0.2 hosts are connected to the external storage where is stored the VM and data warehouses. ESXi 4.1 is compatible with the version in the format/VMFS and VMDK/version of the format of the existing data? Guests of ESXi 4.1 will be able to set up warehouses of data and power ok the virtual machine?

    George.

    There are two things to look at. The first is the version of the VMFS file system, which is - as you say - 3.21 VMFS, so it's ok. The second is version of virtual equipment of the virtual machine, which must be at least 4. (see http://kb.vmware.com/kb/1003746) With ESX 3.02, this should be the case.

  • Help with vdmk migration of RDM using vmkfstools-i

    Hi all

    I need to migrate a 590GB hard file to a RDM in virtual compatibility mode.

    I want to avoid using a method of file copy there are has over 6 million of small files on this volume.

    I'm came across a blog that said this could be done using the ' vmkfstools-i "command and I saw other posts here on the community forums that tell a similar story."

    I have three questions:

    • The virtual machine should be turned off when you use "vmkfstools-i" command?

    • The following syntax would be just so executed with the VM source directory and assuming that vmhba1:0:2:0 is the path to the RDM LUN on the SAN: vmkfstools rdm d-i F - drive.vmdk F-Drive - rdm.vmdk: / vmfs/devices/drives / vmhba1:0:2:0

    • Should I join/create the ROW for the virtual machine before or after that I use "vmkfstools-i" command?

    Thank you!

    The virtual computer source must be turned off.

    Your command syntax is good

    The command will create the mapping RDM once finished you just add to your virtual machine

  • HOW CAN I GET A HP LASERJET 4V IN ORDER TO PROPERLY USE THE OPERATING SYSTEM TO XP PRO AND USB USING A PARALLEL CABLE?

    HOW CAN I GET A HP LASERJET 4V IN ORDER TO PROPERLY USE THE OPERATING SYSTEM TO XP PRO AND USB USING A PARALLEL CABLE?

    The printer works at all with this cable?

    The cable has recognized and installed by Windows XP when you logged on to the computer?

    If the cable has been recognized, what steps have you taken to install the printer then (be as accurate and complete as possible)?

    You get an error message?  If so, please provide, without paraphrasing.

    This printer has already been installed on this computer?  If so, with what type of connection?

    And especially, what is the brand and model of the USB to parallel cable?  Many of them do not work.  See, for example, the comments here , which suggests that 25% of the units will simply not work.  This seems to be one of these products you should buy at a local store, rather than on the Internet, then you can continue taking it back until you get a working unit.

    There is no way to update the version of perpetual license / DWCS6 drive to the creative cloud, they are two completely separate programs. There used to be a discount for the Creative Suite owners switch to CC, but that ship has sailed.

  • If I already downloaded and am using photoshop, if I update the 19.99/month plan, but choose illustrator, I will no longer have access to photoshop?

    ^^

    Hello

    I see you are using Photoshop and Lightroom for $9.99 / month (with the same id in the forums adobe) If you upgrade to full creative cloud for $19.99 (student & teacher), you always be always will be able to use photoshop, since it is a complete package.

    and if you add Illustrator as a single application for $19.99, it's just an add on and you will be able to use photoshop.

    I have a VBA application that fills the data in an Acrobat form.  Do I have to distribute a complete Acrobat on each machine that uses this application (it will be disastrous) or is there a way I can use the software Acrobat reader only.  I use the next AcroExch.App and AcroExch.PDDoc object to the form.  I hope there's a distribution object, I can use the full application and not because I don't want users to have access to forms and to keep the cost down.

  • question about SQL and VMDK places

    Hello world. Im kinda new here so please be gentle

    I'm confused on the locations of the files for sql.

    At this moment I have 1 with 3 vmdk files sql server executes a muscular 100 GB sql database.

    My disks are as follows

    1 OPERATING SYSTEM

    2 DB

    3 newspapers

    They are all thick and they are all stored with the virtual machine in the virtual machine configuration.

    It lies in a cluster HA/DRS and we use them both.

    The question boils down to performance.

    If my VM is stored on DATASTORE_A and the VM folder on this data store has all the VMDK files in it, it would be safe to say that they are all on the same disk as much as vsphere is concerned.

    Now to get best performance, I want to separate my VMDK files to separate data (with faster operation) warehouses to avoid conflicts of drive on my current data store. What is the right way to go about this?

    How separate you your VMDK to other data warehouses, and enjoy other performance data store? WE do not use DTS at all so im sure it although we use HA/DRS in our group... and yet, I don't think that it is important in this case... just more of an FYI.

    What do you do to get your SQL servers to run in vmware?

    Seems like a basic question.

    The answer seems easy. Separate disks so that they do not fight.

    'S virtually done it with VMDK but the data store underlying is 1 speed and they all exist on this subject, so... How to separate them at that level for best performance?

    Also... once I keep them separated, how can I keep my sanity by knowing my VMDK are not with the virtual machine? This kind of made a mess . Of course the performance takes a front seat for my mental health.

    Thank you all

    1. If I sVmotion my other vmdk files via the advanced options of one in another data store, it will create the files folder structure based on my VM name and place the vmdk inside?  (I guess I could just test it and see).

    Yes, the VM configuration file (.) VMX) will be modified to point to the new location of the virtual disk. You can use the virtual machine property editor to check for this, once the Storage vMotion.

    2. with regard to the disk controller, I assume you mean a virtual controller by VMDK in the vmx / correct the settings of the virtual machine and not a phyical on the hardware controller? (IM pretty sure I know the answer here but I just want to be clear).

    Yes, the virtual controller is correct.

    If so, what type of controller? LSI Logic or it would benefit all a paravirtual adapter?

    As long as your operating system is supported, go with the PVSCSI every time - especially for newspapers and the controller file data.

  • What are the MINIMUM requirements for the multitasking DW, PS and FL using codecs "easy"?

    Will MINIMUM of Adobe system requirements, please suggest a less so-called CPU, memory and system disk i/o for multitasking Dreamweaver, Photoshop and Flash using codecs 'easy' (DV and HDV) only.

    It is an impossible question to answer.

    Is multitasking DW, PS, FL and PR a matter of editing an html file, switch to ch to change a single image, moving to FL to create a SWF file and switching to PR to change a title, or he has DW make a complete validation on several DHTML, including SES files, performing an action resize in PS to a few thousands of images , encoding large files in FL and PR make an export to a complex long form BRD?

    It makes a difference. One thing is certain, the memory can be just as important as the CPU. Something less than 12 or 16 GB will be a huge limitation, but also nothing less than an i7 with HT technology. Three discs is the bare minimum with this kind of multitasking, unless the first description of multi - load a minimum applies.
