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
between the VMware VCB Proxy server and VMware ESX server, the settings detailed in "2.1.2.5 VMware ESX"
(page 11) should be used.
