Managing Disk Volumes

This document describes redundant array of independent disks (RAID) concepts,
and how to configure and manage RAID disk volumes using the SPARC Enterprise
T2000 server’s onboard serial attached SCSI (SAS) disk controller.

This chapter contains the following sections:

“Requirements” on page 45

“Disk Volumes” on page 45

“RAID Technology” on page 46

“Hardware Raid Operations” on page 48

Requirements

To configure and use RAID disk volumes on the SPARC Enterprise T2000 server, you
must install the appropriate patches. For the latest information on patches for the
SPARC Enterprise T2000 server, see the latest product notes for your system.
Installation procedures for patches are included in text README files that
accompany the patches.

Disk Volumes

From the perspective of the SPARC Enterprise T2000 server’s on-board disk
controller,

disk volumes

are logical disk devices comprising one or more complete

physical disks.
