Install and configure the disk array The HP service representative performs these tasks: • Assembling hardware and installing software • Loading the microcode updates • Installing and formatting devices After these tasks are finished, you will use Remote Web Console, Command View, Command View XP - HP XP1024 | HP StorageWorks Disk Array XP operating system configuration guide: - Page 13
for the disk array ports After the disk array is installed, you must set the host mode for each disk array port to match the host OS. Set the host mode using LUN Manager in Remote Web Console XP (shown), Command View XP, or Command View XP Advanced Edition. If these are not available, the HP service - HP XP1024 | HP StorageWorks Disk Array XP operating system configuration guide: - Page 14
For the XP1024/XP128 arrays, the host mode can also be set at the port information window in Command View XP AE. Setting the System Option Modes The HP service representative sets the System Option Mode(s) based on the operating system and software configuration of the host. 14 Installation - HP XP1024 | HP StorageWorks Disk Array XP operating system configuration guide: - Page 15

This process is also called "LUN mapping." In Remote Web Console and Command View, LUN mapping includes - HP XP1024 | HP StorageWorks Disk Array XP operating system configuration guide: - Page 21
