Unmounting all the CD-ROMs of all VMs in a cluster

This is an easy recipe to start with, but one you can really make it work for your existing infrastructure. The workflow will unmount all CD-ROMs from a running VM. A mounted CD-ROM may block a VM from being vMotioned.

Getting ready

We need a VM that can mount a CD-ROM either as an ISO from a host or from the client.

Before you start the workflow, make sure that the VM is powered on and has an ISO connected to it.

How to do it...

1. Create a new workflow with the following variables:

   Name	Type	Section	Use
   cluster	VC:ClusterComputerResource	IN	Used to input the cluster
   clusterVMs	Array of VC:VirtualMachine	Attribute	Use to capture all VMs in a cluster

2. Add the getAllVMsOfCluster action to the schema and assign the cluster in-parameter and the clusterVMs attribute to it as actionResult.

3. Now, add a Foreach element to the schema and assign the workflow Disconnect all detachable devices from a running virtual machine.

4. Assign the Foreach element...
