vSphere 4 + ESXi 4: Image using a RDM cannot be migrated to a different host, card held locally RDM?...

I have two servers ESXi 4.0 and one of vSphere (4.0), their management. These two ESXi hosts can see a LUN on a NetApp FAS2020 and they see it as the same device (if I change the name on the same host, its automatically changed on another host). I have also a larger NFS volume that I use for my VMDK files, and it is on both ESXi hosts. All my guests use the NFS data store for their primary, and several disks use it to a secondary drive.

I have a specific host to use an iSCSI LUN of the NetApp for its secondary drive. I added it as a Raw Device Mapping (tried physical and virtual), but when I go through the installation program, must I store a map file of the LUNS on a data store. Unfortunately, the single data store, you have an option is the LOCAL DRIVE of the ESXi host. As soon as you start the system and try to migrate, it fails because the second vServer cannot reach the mapping file that is located on the first vServer.

What I'm doing wrong here... Why can't store the mapping file ROW with the rest of this VMDK and file EXCHANGE virtual servers?

I think it is because the file pointer needs a block device. You can check KB for details. And Yes, you need another logical unit number (type vmware) and create a VMFS on it to store the pointer files.

    Hello, my saver

    Currently, I have an Esxi, but before I used a picture of WMware player to my virtual server and I know, I use Vsphere to work with my 5.1 ESsxi, I just want to know if I can use my VMware Player image in VSphere for Esxi? and if the answer is Yes, how?

    Thanks for your help.

    Right, so use VMware converter to do this as indicated in my previous post.

  • Backup error ESXi 5.5 using vicfg

    Is 192.168.75.18 the IP address of your ESXi host (without typos etc.) and is this place works?

    Probably you have an error in the command line you entered, the error message print "https://=192.168...

  • bad, ugly of vSphere good ESXi,

    We plan to make our upgrade from ESX 3.5 to vSphere with ESXi.

    Our environment is 25-35 guests, especially HP and some Dell.

    What would we be careful with ESXi (in addition to not having a console and scripts, etc.)?  Limits?

    I think it will take a bit of getting used to vCLI and vMA since we have been accustomed to the console on the host since ESX 2.0.  I had heard some security problems associated with ESXi, but I don't remember where I heard that someone has any information that might be useful?

    Besides the ESXi Chronicles Blog, someone has good blogs, etc. especially recommended for ESXi?

    BTW - are going to change the name of vSpherei?

    I think SSL/SSH is safe enough.

  • P2V conversion of variable with the physical air to ESXi VirtualCenter environment using a laptop as the converter/transport

    Hello

    I'm looking at a collection of physical servers for migration to a virtualized environment: the goal is to move from a huge collection of 30-40 physical servers of different brand/model/specification and physically scattered in many places for a single grid filled with boxes of ESXi.

    I have a question about the best way to conduct the physical to the virtual conversation process (don't worry - looking for high level only indicatively!).

    For the bottom, 30-40 physical servers are not connected/not related in terms of operating system (ie. not a member of a common domain, run multiple operating systems - for most variants of Windows NT4/2000/2003 etc) but are connected to the same physical network infrastructure and all contribute to a common function. In short they can each be considered in the sense of functional servers 'specific application.  Further and I think very important to mention, the current environment and the new rack/rigging are (to be) exploited isolation - IE. Air-ajar.

    I see my new rack running DL380s running ESXi and images on a San shared and connected them via a dedicated switch. with a VirtualCenter instance server in there somewhere to hang together... not sure at this stage as to where I should do that in a Machine virtual itself (preferable to reduce the hardware requirements), or if a physical process adding unique 'management' style server would be more appropriate.  I also have a laptop to 'manage' the environment which will be connected to the switch on an ad hoc basis.

    I want to be able to do is use this notebook to go to each of the existing physical servers in turn (connection on its network switch) and create a virtual image of it (hot or cold, although I guess the cold option seems nicer than the existing server remains completely intact) before resuming the laptop computer to the virtual test bench , and then "push" the virtual image in VirtualCenter and on an ESXi host (with any post import etc. reconfiguration tasks that may be required).  I'm not sure what components I need where to do this - specifically which allows me to capture the physical server while having no connectivity with the VirtualCenter Server?  I've read through documentation/notes Converter Enterprise - this would be the correct way to go?  If so I should the Converter Enterprise Server component installed on the VirtualCenter server or the laptop itself (ie. What must be connected to what during the capture process?) ?  Or is there a simpler approach of independent style should I watch?

    All advice/aid/comments greatly appreciated in advance!

  • Vectorize an image using Labview

    Hello world!

    So, I work with a 3D cutting machine (Roland MDX - 15) and I'm supposed to design a program that can load images and burn them on a piece of wood using Roland MDX - 15.

    What I've done, is to create a program where you can draw a picture using the tools of sketch of Labview and the machine will sculpt.

    The machine is capable of carving the image using vectors (she follows lines point by point).

    Now, I have to do the same thing, but an image that I have load in Labview. Therefore, I need to vectorize the image so that the machine gets a set of lines to draw. A program that is already it is Dr.Engrave (see youtube if you need to understand what I need).

    So, anybody know a 'simple' way to transform an image into a set of vectors?

    Thanks in advance!

    Hello VGans,

    I assumed that when you talk of tracing any edge detection method would be allowed to help you get started.

    If it is a false assumption, then let me know.

    Keeping this in mind:

    Already taken a peek at the "IMAQ CannyEdgeDetection' VI?

    This could be a good starting point for tracing purposes.

    Can you let me know if that's what you're looking for?

  • some computers cannot acquire images using the PCI-1410

    I have a big problem in the acquisition of the images using the PCI-1410.

    It was a standard camera (SONY XC-ES). The test of the device is OK with my computer.

    I can not get a correct image via MAX. Also, I try to use the file of the camera for that camera.

    But it did not work properly.

    I consulted it toward the Korea of NEITHER and they discover THAT PCI-1410 worked properly with different computers.

    So, I try to change PC. Most of my computers cannot acquire the image even if the unit is OK of MAX.

    However, only a few computer works properly. (Work computers are from SAMSUNG. The other

    computers that did not work propely, were assembled in the lab.) (I have tested almost 6 computers for this purpose.)

    The problem is that there are at least 3-4 PCI ports for our applications. The work computer (SAMSUN) only has 2 ports PCI.

    What should I do to select the right computers? I can't buy dozens of computers to test the PCI-1410.

    Why is this kind of problem occurs?

    Thanks in advance for your advice. (Email: [email protected])

    Hello

    We also had a lot of problems in the past with different PCs and the problem came from the motherboard. Since that time, we only use motherboards with intel because we know that labview works very well with them.

    It was 2 or 3 years ago, and I thought that the problem has been resolved since then... you know the type of motherboards you use?

    The question is more how you want that they be indexed like that?

  • Continuous imaging using vision builder

    Hello, I use NI 1744 and want to know how to get and record continuous images using Vision Builder. I am in a position to acquire and maintain a single image but cannot acquire continuous images.
    Looking forward for your help.

    Bürki,

    You try to save the images continuously as a movie?  This is not supported in VBAI, however if you want to align continuous images individually you can try to change your pattern of State inspection to repeat your current inspection and the transition to the stage stop only after that your current inspection was conducted a defined number of times.

  • Acquisition of images using PCI-1426 and Camera Link Camera

    Hello

    I am writing a program to capture images of a Camera Link camera via the PCI 1426 acquisition card in LabVIEW. The problem that I am facing is that I am unable to find the correct controls in the functions palette to start the image capture. Could someone tell me please how much control I'm supposed to use?

    I've worked on similar request sometimes back, I used IEEE 1394 camera, so once I found the correct block diagram controls I should be able to go from there.

    Thanks in advance,

    Sandeep

    Hello Kristen,

    Thanks for the suggestion. I was able to solve this problem. I think that was what was causing the problem I have LabVIEW 8.6 installed on my system and he had the Vision Acquisition System (VAS) 8.5.1. But, once I installed VAS 8.6 I saw the IMAQ in the functions palette.

    I'm guessing that LabVIEW 8.6 does not recognize the toolboxes of previous versions.

  • Which is faster a bit manipulation to the table or image using the vision

    I have to perform an operation on an image.  It involves the calculation of the new locations for the pixels for each pixel of the image.  Which is the fastest way to do it.  Manipulate the pixels as elements of the array for loops, or manipulate the pixels of an image using vision tools?

    Thank you.

    Hello

    If you can use vision tools to make the manipulation of pixels, it is much faster.

    Hi carolewyne

     

    1. What are the brand and model of the laptop?

    2. you have software installed for the camera to use?

     

    If you want to take a photo using the camera in the phone, then maybe you should use a utility support for the device that is provided by the manufacturer. It will help you get the image using the camera. You can visit the manufacturer's Web site and download the software for the device is functioning correctly.

     

    I hope this helps.
