1 Overview of HP StorageWorks XP Volume
Retention Manager
The Volume Retention Manager allows users to protect data in your storage system from I/O operations
performed by mainframe hosts. By default, all mainframe volumes are subject to read and write
operations by mainframe hosts. Because of this, data is exposed to damage or loss if a mainframe
host performs erroneous write operations. Confidential data could be compromised, read, or copied,
because read operations are allowed by default on mainframe volumes. By using Volume Retention
Manager, you assign access attributes to each logical volume thus restricting read and/or write
operations and preventing unauthorized access to data.
