Overview

Volume Security protects data in your HP storage system from I/O operations performed at mainframe hosts. Security can be applied to logical volumes so that specified mainframe hosts are unable to read from and write to the specified logical volumes. Volume Security also enables you to prevent data on logical volumes from being accidentally overwritten by erroneous local or remote copy operations.

Volume Security can be used in conjunction with the Volume Security Port Option. This optional program is used to specify storage system ports through which hosts can access logical volumes.

Using Volume Security you can manipulate up to 64 hosts and 65,280 logical volumes for one storage system. Volume Security also enables you to create up to 64 security groups, 64 host groups, and 64 Volume Groups for one storage system.

Volume Security operations are performed using the licensed HP StorageWorks XP Remote Web Console software. The Remote Web Console software communicates directly with the storage system via a local-area network (LAN). Remote Web Console displays detailed Volume Security information and allows you to configure and perform Volume Security operations for the mainframe systems data stored on the storage system. For further details, see the HP StorageWorks XP24000/XP20000 Remote Web Console User’s Guide.

To apply port-level security, you must install the Volume Security Port Option. Before installing this program, ensure that Volume Security is already installed. For details on the installation procedure, see the HP StorageWorks XP24000/XP20000 Remote Web Console User’s Guide.

•In the Hitachi TrueCopy™ for Mainframe User's Guide, primary volumes are often referred to as M-VOLs, or main volumes. Also, secondary volumes are often referred to as R-VOLs or remote volumes. In the Hitachi ShadowImage™ for Mainframe User's Guide, primary volumes are often
