// VMware vRealize Orchestrator action sample | |

// Get all compatible datastores for a given host, resource pool, and virtual machine. | |
// The datstore must have enough free storage space necessary for the VM, and must be | |
// accessible and not in an overall status of "Red". | |
// | |
// For vRO 7.0+/vCenter 6.0+ | |

// Action Inputs: | |
// host - VC:HostSystem - vCenter host | |
// vm - VC:VirtualMachine - vCenter VM | |
// pool - VC:Resource Pool - vCenter resource pool | |
// | |
// Return type: Array/VC:Datastore - datastores compatible with the given host and VM | |
var compatibleDatastores = []; | |
// use OOTB function to find all datastores for the given host/pool/VM | |
