Physical and Logical Devices in SRM
For Storage Devices, SRM provides a summary of the allocated and unallocated space in all the physical devices attached to the client. Information is presented as a bar chart and also presented in a tabular format. This summary provides specific information on the device, such as device name, manufacturer, partitions, etc. In addition to this specific information about each physical device, information is also available about the logical devices associated with it. Storage Devices node appears only for the SRM Windows File System, Unix, Exchange and SQL Agents.
The Logical Device summary provides the following information:

Volume groups related information is displayed by SRM UNIX File System Agent only. |
The File System Agents perform data collection and provide report and summary information on logical and physical devices including RAW partitions on the devices. The database Agents perform data collection on the logical devices and provide reports and summaries on the logical devices associated with the database. For SRM Windows and SRM NetWare Agents, file systems are listed under Volumes in the CommCell Console; for SRM UNIX, they are listed under File Systems. Logical/physical mapping will display all the physical devices if control files, redo logs, archive logs and data files reside in different disks.
For Logical/physical device mapping on Oracle Database, you need to:

Logical/physical mapping does not work if Oracle Database resides on raw logical volumes. |
Logical/physical device mapping for Oracle Database on UNIX raw devices or with ASM (Automatic Storage Management) works on the the following platforms:
