‘Connection Control Operation Failed for Disk’ with Content Libraries

When trying to attach an ISO stored in a VMware Content Library the operation fails with the following error-

Connection control operation failed for disk 'sata0:0'.

To resolve follow these steps-

  • Head over to the old Flash client at https://vcsa/vsphere-client
  • Power off the VM the ISO is being attached to
  • Select the VM then ‘Edit Settings…’
  • Change the CD drive to ‘Client Device’
  • Expand CD drive options and change the Device Mode to ‘Passthrough CD-ROM’
  • Hit ‘OK’ to reconfigure the VM

Edit VM settings again and reattach the Content Library ISO as normal.
