Before you set up a Smart Array Controller as a boot device, consider the following: • When you use a Smart Array logical drive as a boot device running HP-UX, you are limited in the configuration tasks you can perform with the saconfig configuration utility. The saconfig utility sees the logical drive as being in use, so configuration changes affecting that drive are not allowed until the drive is no longer the boot device. • When you are not using a logical drive as a boot device, if you clear the controller's configuration the logical drive is also deleted. If you want a logical drive to remain set up as a boot device, configure a logical drive and then complete the entire boot setup process again. • If you have trouble accessing RAID boot data, only limited troubleshooting tools are available. HP recommends booting from an alternative boot media and using STM and sautil online tools. For more information, see Chapter 4: "Troubleshooting" (page 65). Configuring a logical drive offline using ORCA Smart Array controllers support Option ROM Configuration for Arrays (ORCA) on HP Integrity servers. ORCA is a menu-driven system for creating, editing, and deleting logical drives. To access ORCA, follow the procedures in the installation guide for your controller. Installation guides are available on the HP website at: http://www.hp.com/go/hpux-iocards-docs Click the link for your HP-UX version. Installation guides are listed alphabetically in the "Setup and install - general" section. IMPORTANT: ORCA appearance, functionality, and keystrokes are not the same for all Smart Array controllers. This section provides a generic procedure using a P400 controller as an example. Always follow the on-screen prompts when using ORCA.

Configuring a logical drive offline using ORCA
Smart Array controllers support Option ROM Configuration for Arrays (ORCA) on HP Integrity
servers. ORCA is a menu-driven system for creating, editing, and deleting logical drives.
To access ORCA, follow the procedures in the installation guide for your controller. Installation
guides are available on the HP website at:
http://www
.hp.com/go/hpux-iocards-docs
Click the link for your HP-UX version. Installation guides are listed alphabetically in the “Setup
and install — general” section.
IMPORTANT:
ORCA appearance, functionality, and keystrokes are not the same for all Smart Array controllers.
This section provides a generic procedure using a P400 controller as an example. Always follow
the on-screen prompts when using ORCA.
