To configure a local device as an RDM disk:<\/p>\n\n\n\n

  1. Open an SSH session to the ESXi\/ESX host.
    <\/li>
  2. Run this command to list the disks that are attached to the ESXi host:

    # ls -l \/vmfs\/devices\/disks
    <\/li>
  3. From the list, identify the local device you want to configure as an RDM and copy the device name.

    Note<\/strong>: The device name is likely be prefixed with t10. and look similar to:

    t10.F405E46494C4540046F455B64787D285941707D203F45765
    <\/li>
  4. To configure the device as an RDM and output the RDM pointer file to your chosen destination, run this command:

    # vmkfstools -z \/vmfs\/devices\/disks\/diskname<\/em>\/vmfs\/volumes\/datastorename<\/em>\/vmfolder<\/em>\/vmname<\/em>.vmdk

    For example:

    # vmkfstools -z \/vmfs\/devices\/disks\/t10.F405E46494C4540046F455B64787D285941707D203F45765 \/vmfs\/volumes\/Datastore2\/localrdm1\/localrdm1.vmdk

    Note<\/strong>: The size of the newly created RDM pointer file appears to be the same size and the Raw Device it it mapped to, this is a dummy file and is not consuming any storage space.
    <\/li>
  5. When you have created the RDM pointer file, attach the RDM to a virtual machine using the vSphere Client:
    1. Right click the virtual machine you want to add an RDM disk to.<\/li>
    2. Click Edit Settings<\/strong>.<\/li>
    3. Click Add<\/strong>.<\/li>
    4. Select Hard Disk<\/strong>.<\/li>
    5. Select Use an existing virtual disk<\/strong>.<\/li>
    6. Browse to the directory you saved the RDM pointer to in step 5 and select the RDM pointer file and click Next<\/strong>.<\/li>
    7. Select the virtual SCSI controller you want to attach the disk to and click Next<\/strong>.<\/li>
    8. Click Finish<\/strong>.
      <\/li><\/ol><\/li>
    9. You should now see your new hard disk in the virtual machine inventory as Mapped Raw LUN<\/strong>.<\/li><\/ol>\n\n\n\n
