604 IBM System Storage DS3500: Introduction and Implementation Guide

20.1 DS3500 SAS storage configuration on SLES 11 using

RDAC

In this section we discuss how to add a logical drive to an SLES 11 using DS3500 SAS

storage using RDAC multipath driver

20.1.1 Preparing for the installation

For our setup, we used the following hardware and software components:

򐂰 HS21 BladeServer.

򐂰 Dual Port 6 Gbps SAS HBA.

򐂰 Two SAS Connectivity Modules

򐂰 DS3500 Storage Subsystem

򐂰 A management workstation running the latest version of DS Storage Manager.

򐂰 The latest version IBM RDAC drivers for Linux.

򐂰 SuSE Linux Enterprise 11

Figure 20-1 Hardware setup

Only in SAS configurations, zoning configuration is not necessary except when booting from a

SAS Storage. Like in this case, zoning is not required and we are attaching a logical drive to

an operating system that is already installed on local hard disks.

The following are recommendations before mapping the logical drive(s) to the server:

򐂰 Check the compatibility in IBM System Storage Interoperation Center(SSIC) web site

(http://www-03.ibm.com/systems/support/storage/config/ssic) to be sure it is a

supported environment and also to be sure which multipath driver is needed (RDAC,

MPIO, DMM, etc). The SSIC can provide the interoperability matrix, and is a selection

driven tool where you provide the criteria for your configuration.
