Override the expiration date on a tape or disk volume

owned by another user
Override the owner UIC protection of a volume
The VOLPRO privilege permits control only over volumes that
the user's process can mount or initialize. Volumes mounted with
the /SYSTEM qualifier are safe from a process with the VOLPRO privilege
as long as the process does not also have the SYSNAM privilege.
Exercise extreme caution when granting the VOLPRO privilege.
If unqualified users can override volume protection, the operating
system and service to others can be disrupted. Such disruptions
can include destruction of the database and exposure of confidential
information.
The VOLPRO privilege lets a process perform the following
tasks:
