Storage Devices

Overview

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:

File system related information, such as the volume name, total and free space available in the volume, etc.
Volume groups related information, such as the volume group name, total and free space in the volume, logical and physical volume count, etc.

Volume groups related information is displayed by SRM UNIX File System Agent only.

Database related information, such as the name of the database, the logical device in which the database is installed and additional information about the database.

Physical and Logical Devices in SRM

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. For more information on physical and logical devices associated with the file system agents, see SRM Windows File System Agent Summaries, SRM UNIX File System Agent Summaries and SRM NetWare Proxy Agent Summaries.

For Logical/physical device mapping on Oracle Database, Data Collection must be run using both SRM Agent for the Oracle Database and the SRM Windows File System Agent. However Logical/physical device mapping for Oracle Database on UNIX raw volumes or with ASM (Automated Storage Management) is reported only by Windows and Red Hat Linux.

For more information on summaries for each SRM Agent, see SRM Summaries.
