1. Introduction

This manual outlines the different procedures involved in reconfiguring online storage devices
on Red Hat Enterprise Linux 5 host systems. Online storage devices typically use any of three
protocols: fibre channel, iSCSI, and Serial Attached SCSI (SAS).
The scope of this manual is limited to adding, removing, monitoring and management of online
storage devices. This manual does not discuss the fibre channel, iSCSI, or SAS protocols in
detail. Refer to other documentation for more information about these protocols.
This manual assumes that you have advanced working knowledge of Red Hat Enterprise Linux
