Storage Subsystem configuration.
Root User ID. The UID of the user who has root access privileges to the HPSS namespace. This only
applies if the Root Is Superuser flag is set.
COS Change Stream Count. The number of background threads that run in the Core Server to process
Class of Service change requests. This field may be overridden on the Storage Subsystem configuration.
Global Flags:
Root Is Superuser. If checked, root privileges are enabled for the UID specified in the Root User ID
field. If the box is not checked, the UID specified in the Root User ID field will not have root privileges.
Root access privileges grant the specified user the same access rights to each namespace object as the
object’s owner.
Can change UID to self if has Control Perm. If checked, then when a user has control access to an
object, the user can take over ownership of the object by changing the UID of the object to the UID
associated with the user.
Can change UID if has Delete Perm on Security ACL. If checked, then when a user is listed with
delete permission in the security ACL of the CORE server that owns the object, the user can change the
UID of the object to any valid UID.
Object names can contain unprintable characters. If checked, then users of the HPSS system may
create objects (e.g., files, directories, etc.) with names containing unprintable characters as viewed
through the 7 bit ASCII character set. If this option is off, any attempt to name an object using
unprintable characters will be disallowed. The range of printable characters is 0x20 (blank) through 0x7E
(tilde) in the 7 bit ASCII character set.

information for creating, modifying, and deleting them.
For a conceptual overview of subsystems, refer to the HPSS Installation Guide, specifically Storage
