storage pool
storage pool. The set of disk volumes that contain files for a specific fileset or that can be
used to contain files for a specific fileset. The storage pool includes the creation pool.
storage-pool file. A file containing a list of disk volumes to be used when creating new files
in a fileset. As these volumes are filled, more volumes can be added to the storage-
pool file.
superblock. The part of the OSS environment that contains all the information about the
current state of the OSS file system. The superblock contains such items as the free
list and the size of inodes.
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.
