/DEVICE=device-spec

    Specifies the disk volume containing the quota file. SYSMAN
    validates the device specification and translates any logical
    name in the target environment before deleting the UIC entry.

    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.
