2 About Volume Retention Manager
Operations
Volume Retention Manager enables you to set access attributes for Mainframe volumes. This chapter
explains overview of access attribute setting operations.
Access Attributes
To restrict read and write operations, an access attribute must be assigned to each logical volume.
Volume Retention Manager enables you to assign one of the following access attributes to each logical
volume:
• Read/Write
If a logical volume has the Read/Write attribute, mainframe hosts can perform both read and
write operations on the logical volume. All mainframe volumes have the Read/Write attribute by
default.
• Read Only
If a logical volume has the Read Only attribute, mainframe hosts can perform read operations but
cannot perform write operations on the logical volume.
• Protect
If a logical volume has the Protect attribute, mainframe hosts cannot access the logical volume.
Mainframe hosts cannot perform either read nor write operations on the logical volume.
Volume Retention Manager does not allow you to assign any access attribute to:
• open-system volumes
• logical volumes (that is, logical devices) that are not mapped to physical devices.
To assign access attributes to logical volumes, you use HP StorageWorks XP Remote Web Console
to start Volume Retention Manager and then set access attributes in the Volume Retention Manager
window. You can also use a spreadsheet.
Figure 1 on page 9 is an excerpt from the Volume Retention
Manager window. This example shows access attributes of the logical volumes 00, 01, and 02.

Volume Retention Manager Spreadsheets
You can use Configuration File Loader to set access attributes. Configuration File Loader allows you
to save access attribute settings in a file (called spreadsheet), and to set access attributes concurrently
to multiple logical volumes using a spreadsheet. Configuration File Loader makes the following
operations easier:
