This playbook uses the manual trigger for selecting a VM and ejecting a CD-ROM for that VM. It will check the first, second and third indices of Disk and if it finds one in any of those slots, it will eject it. It allows manually triggering this eject operation from the PC VMs List view.
Be sure to note the Prism Central version the Playbook was exported from. This is important because Playbooks cannot be imported to an older version of PC than they were exported from. For example, a Playbook from a pc.2021.1 version cannot be imported into a PC on pc.2020.11 version for compatibility reasons.
