VMware develops a range of virtual machine software products. These programs create virtual hardware for operating systems to install and run on, allowing these systems to run inside of other operating systems. In addition to installing an operating system on a virtual machine, you can also convert existing operating systems installed on physical machines into VMware virtual machines. In some cases, when running VMware ESX, the newly-created virtual machine's virtual hard disk is created as an IDE disk, instead of a SCSI disk, which decreases performance and causes other errors. You can use the ESX console and VMware interface to convert the IDE virtual drive to a virtual SCSI drive.

Skill level:


  1. 1

    Access the VMware ESX service console and log in with your user name and password.

  2. 2

    Navigate to the virtual machine's directory by typing "cd /vmfs/volumes/<datastore_name>/<vm_name>/" into the VMware ESX console, replacing "<datastore_name>" with the name of the virtual machine's datastore and "<vm_name>" with the virtual machine's name, and pressing "Enter."

  3. 3

    Type "nano disk.vmdk," replacing "disk.vmdk" with the name of the VMware disk file, and press "Enter."

  4. 4

    Locate the line "ddb.adapterType = "ide"" using the text editor.

  5. 5

    Change "ide" on the line in the text editor to "lsilogic."

  6. 6

    Exit the text editor by pressing "Ctrl" and "X" at the same time, then press "Y" to save.

  7. 7

    Access the graphical VMware client.

  8. 8

    Right-click the virtual machine and click "Edit Settings."

  9. 9

    Click the IDE virtual disk in the list of virtual hardware devices.

  10. 10

    Click "Remove" and "OK." Do not click "Remove from Disk," which will delete the hard drive file and make it unrecoverable.

  11. 11

    Click "Add," "Hard DIsk" and "Use Existing Hard Disk."

  12. 12

    Navigate to the "/vmfs/volumes/<datastore_name>/<vm_name>/" folder and double-click the .vmdk file you edited.

  13. 13

    Choose the "LSI Logic" controller when prompted.

Tips and warnings

  • If your virtual machine has a virtual CD drive connected, you may need to remove the CD drive and re-add it to the machine.
