super ID
super ID. On HP NonStop S-series or NonStop NS-series systems, a privileged user who
can read, write, execute, and purge all files on the system. The super ID is usually a
member of a system-supervisor group.
The super ID has the set of special permissions called appropriate privileges. In the
Guardian environment, the structured view of the super ID, which is (255, 255), is most
commonly used; in the OSS environment, the scalar view of the super ID, which is
65535, is most commonly used.
system. A single copy of the HP NonStop operating system and the collection of hardware
groups in which it runs.
target directory location (TDL). The absolute pathname within the target OSS
environment where the OSS files for configuration are placed. One TDL can contain
files for a single product or multiple products. TDL names are contained in the
A7CINFO file for each product and are transmitted to the target system in the
activation package instructions.
target subvolume (TSV). The subvolume name of a disk location on the target system
where the software files for configuration are placed. One TSV can contain files for a
single product or multiple products. TSV names are contained in the A0CINFO file for
each product and are transmitted to the target system in the activation package
instructions.
TDL. See target directory location (TDL).
terminal. A type of character special file that conforms to the interface description in
Clause 7 of ISO/IEC IS 9945-1: 1990.
TSV. See target subvolume (TSV).
UID. A nonnegative integer that uniquely identifies a user within a node.
The UID is a scalar number consisting of the group number multiplied by 256 and
added to the member number; for example, the UID of the super ID is (255*256) + 255,
or 65535. The UID is used in the OSS environment for functions normally associated
with a UNIX user ID. See also user ID.
unmount. To make a fileset inaccessible to the users of a node.
user ID. The unique identification of a user within a node.
In the Guardian environment, the term “user ID” usually means the group number and
member number pair; for example, the user ID of the super ID is usually described as
(255, 255). In the OSS environment, the term “user ID” usually refers to the single
number that is the scalar view of the user ID—a number called the UID. See also UID.
UTC. See Coordinated Universal Time (UTC)
