/DEVICE=device-spec

    Specifies a disk volume on which to enable the quota file.
    SYSMAN validates the device specification. A logical name may be
    specified for device-spec. If so, it is translated in the target
    environment.

    Without a device specification, SYSMAN uses the default disk
    on the target node. Unless you have set a default device with
    the SET PROFILE command, the default disk is the current device
    on the local node or the login default device on another node,
    depending on the established environment.
