106 Storage Management Service
NOTE: The basic Storage Management Service does not provide storage management functions such as
configuring your local and remote attached storage devices, creating and managing software and hardware RAID
configurations, formatting disks, assigning drive letters, and creating partitions and volumes. When the basic
Storage Management Service is installed, you must use Array Manager Console to perform these storage
management functions. See the Array Manager User's Guide for instructions. Alternatively, you can install the
enhanced Storage Management Service, which replaces Array Manager and provides similar storage
management functions. See “Enhanced Storage Management Service Features” for more information.
NOTE: Array Manager does not support volumes management on systems running Microsoft Windows Server 2003.
Basic Storage Management and Array Manager
The basic Storage Management Service and Array Manager are installed by default when using
Express Setup on systems that have an existing Array Manager installation. The basic Storage
Management Service depends on Array Manager to report storage status. Therefore, assuming that the
system meets the Array Manager installation requirements, Array Manager is installed when using
Express Setup to install the Managed System Software package. Managed systems that do not have Array
Manager installed will still be able to perform SCSI diagnostics for direct-attached storage devices;
however, RAID controller and storage diagnostics cannot be performed. See the Array Manager User's Guide
for complete software and hardware requirements.
NOTE: Array Manager is not supported on Red Hat Enterprise Linux operating systems.
Basic Storage Management Tree Objects
The basic Storage Management is accessible by selecting the Storage tree object on the Server
Administrator graphical user interface (GUI). The Storage object expands to display the following objects:
• Array Subsystems
• OS Disks
• Volumes
See the Storage object section in “Instrumentation Service” for a description of the available
storage information.
Enhanced Storage Management Service
The enhanced Storage Management Service provides advanced features for configuring a system's locally
attached RAID and non-RAID disk storage. Storage Management enables you to perform controller and
enclosure functions for all supported RAID and non-RAID controllers, and PowerVault™ 2xxS and
PowerVault MD1000 enclosures from the Server Administrator graphical interface without requiring to
use the controller BIOS utilities.
Using the enhanced Storage Management Service, you can protect your data by configuring data-
redundancy, assigning hot spares, or rebuilding failed drives. You can also perform data-destructive tasks
such as deleting virtual disks or resetting the controller configuration. All users of the enhanced Storage
Management Service should be familiar with their storage environment and storage management.
