Preface

This manual briefly explains the operations that need to be performed by the user in order to connect an

ETERNUS DX410/DX440 or an ETERNUS DX8100/DX8400/DX8700 Disk storage system to a server running

Solaris OS, HP-UX, Windows®, Linux, VMware ESX, or Oracle VM Server via an iSCSI interface.

This manual should be used in conjunction with other applicable user manuals, such as those for the ETERNUS

DX410/DX440 or ETERNUS DX8100/DX8400/DX8700 Disk storage system, server, OS, iSCSI HBAs, LAN cards,

and drivers.

2.1.2.3 Windows®

For Windows®, perform the settings detailed in Table 2.5 and Table 2.6.

Table 2.5 Reservation Conflict Response for Test Unit Ready setting for Windows®

When a Windows® server and ETERNUS DX are connected via a single path connection using an ETERNUS

Multipath Driver, set the host response Sense Data Conversion Pattern to [No Conversion].

If connection is performed without using an ETERNUS Multipath Driver, set the host response Sense Data

Conversion Pattern to [Windows Recommended (When not using GR/ETERNUS MPD or Device Driver)].

Table 2.6 Sense Data Conversion Pattern setting for Windows®

When connecting a Windows®-based VMware VCB Proxy server to the ETERNUS DX, and the LUNs are shared
