3.4 Notes on Creating an HDLM Environment

This section provides notes on creating an HDLM environment.
For details about operating HDLM, see 4.1 Notes on Using HDLM.

3.4.1 Notes on HBAs and HBA Drivers

If you are using the Storport Miniport driver as an HBA driver in Windows Server

2003, install QFE 838894 or later for the Microsoft Storport driver or install

Windows Server 2003 SP1 or later, before installing HDLM.

If you are using multiple HBAs, make sure that the models of the HBAs are the

same. Also make sure that the HBA firmware versions and driver versions are the

same.

3.4.2 Notes on Storage systems

You must not change the vendor ID and product ID of the storage system. If you

change these IDs, HDLM will not be able to recognize the storage system.

If the host and the storage system are connected via a Fibre Channel switch, select

Point To Point as the connection type. If you select FC-AL (Fibre Channel

Arbitrated Loop) as the connection type, an unexpected path error might occur.

Windows can recognize LUNs from 0 to 255. Therefore, set LUNs within the

range from 0 to 255 in the storage system management software.

3.4.3 Notes on HDLM Versions

If HDLM 5.4 or earlier has been installed, uninstall HDLM first and then proceed

with a new installation of HDLM by following the procedure described in

3.5.6 Migrating from HDLM 5.4 or Earlier to HDLM 5.5 or Later.

For HDLM 5.6 or later, the trace files for HDLM versions earlier than 5.6 are

divided into integrated trace files and trace files. The logs for the HDLM

commands and HDLM GUI operations are output to integrated trace files. Trace

information for the HDLM manager is output to trace files. The output

destinations for the files are changed as follows:

• When you migrate from an HDLM version earlier than 04-00 to an HDLM

version 5.6 or later
- Trace files before migration: drive-for-program-installation
