ESXI Guest VM disk expand option grayed out

I have ESXI 5.x Server. I am unable to expand the disk space in one of my VM guest. I have powered off it but still option is grayed out as showed in the image below ... esxi disk not expanding grayed out

Solution

  • YSK is correct. Increasing the size of a VMDK while as an IDE disk is not supported.

    However, there are workarounds for that issue.

    One example: http://www.yellow-bricks.com/2012/11/07/resizing-an-ide-virtual-disk-part-two/

    1. Remove the IDE vmdk from the VM
    2. Edit the “vmdk” file (can be found under cd /vmfs/volumes///)
    3. Change ddb.adapterType from “ide” to “lsilogic”
    4. Add the IDE vmdk to the VM
    5. Change the size of the disk
    6. Remove the IDE vmdk from the VM
    7. Edit the “vmdk” file (can be found under cd /vmfs/volumes///)
    8. Change ddb.adapterType from “lsilogic” to “ide”
    9. Add the IDE vmdk to the VM
    10. Power on the VM and “extend” the partition within the guest OS
