A volume object is one or more ODS-2 or ODS-5
disk volumes. The object consists of multiple volumes when they are
part of a bound volume set. Although you might have access to the
directories and files on the volume, you cannot access them if you
do not have access to the volume itself.
For access information on tapes and foreign volumes,
see the HP OpenVMS System Manager's Manual and the Mount utility documentation in the HP OpenVMS
System Management Utilities Reference Manual.
A volume name can be the volume label, the name
of the device on which the volume is mounted, or a user-specified
logical name. Volume label names can be from 0--12 characters in length.
Types of Access
The volume class supports the following types
Gives you the right to examine file names and print and copy
files on a volume.
Gives you the right to modify or write to existing files on
a volume. Whether the subject may perform the operation on a specific
file is determined by the file's protection. To be meaningful,
write access requires read access.
Gives you the right to create files on a disk volume and to
subsequently modify them. Create access also requires read and write
Gives you the right to delete files on a disk volume, provided
the user has proper access rights at the directory and file level.
Delete access requires read access.
the right to change the protection and ownership elements of the volume.
The class provides the following template profile
and assigns the values during initialization. Although the template
assigns an owner UIC of [0,0], this value is only temporary. As soon
as the object is created, the operating system replaces a 0 value
with the value in the corresponding field of the creating process's
| Template Name|| Owner UIC|| Protection Code|
Users with the VOLPRO privilege always have control
access to a volume. Mounting a file-structured volume as foreign requires
VOLPRO privilege or control access.
Kinds of Auditing Performed
All volume access can be audited, provided the
security administrator enables auditing for the Access event class.

Permanence of the Object
The security profile for a volume object is saved
in the master file directory (MFD) of the disk as SECURITY.SYS.
