/DEVICE=device-spec

    Specifies the disk volume containing the quota file. DISKQUOTA
    validates device specification and translates any logical name in
    the target environment before displaying UIC entries.

    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.
