### #data_disks

    def data_disks() -> ::Array<::String>

**Returns**

- (::Array\<::String\>) --- Mounted data disks. The order is important a data disk's 0-based index in this list defines which persistent directory the disk is mounted to, for example the list of { "myproject-1014-104817-4c2-harness-0-disk-0" }, { "myproject-1014-104817-4c2-harness-0-disk-1" }.

### #data_disks=

    def data_disks=(value) -> ::Array<::String>

**Parameter**

- **value** (::Array\<::String\>) --- Mounted data disks. The order is important a data disk's 0-based index in this list defines which persistent directory the disk is mounted to, for example the list of { "myproject-1014-104817-4c2-harness-0-disk-0" }, { "myproject-1014-104817-4c2-harness-0-disk-1" }.

### #vm_instance

    def vm_instance() -> ::String

**Returns**
