HP Smart Array P700m Controller for Integrity Servers Installation Guide, Second Edition

Configuring a Smart Array Series Controller as a boot device
This section describes the additional steps you must follow to enable your system to boot from
logical drives on a Smart Array Series Controller.
NOTE: To create logical drives, use the Option ROM Configuration for Arrays (ORCA) . See
“Configuring a logical drive Using ORCA offline” (page 13). For more information, see the HP
Smart Array SAS Controllers for Integrity Servers Support Guide .
Planning to install HP-UX on a logical drive
On each Smart Array Controller, you can set up any number of its logical drives as boot devices.
For example, if you have two controllers in a system, and each controller has three logical drives
configured on it, you can set up two logical drives on one controller as boot devices and all three
logical drives on the other controller as boot devices, giving you a total of five boot devices.
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 the HP Smart Array SAS Controllers for Integrity Servers
Support Guide .
Before a Smart Array Controller can be set up as a boot device, the following dependencies must
be met:
• You must have the correct version of the product dependent code (PDC) installed. For
information on the PDC versions needed for each of the supported HP-UX systems, see the
HP Smart Array Controller Release Notes. If you do not have the correct PDC version, contact
your HP representative.
• You must have Smart Array Controller firmware 1.92 or later installed. For information, see
“Verifying and updating controller firmware offline” (page 5).
• HP strongly recommends having an alternate boot device available.
Configuring a logical drive Using ORCA offline
The Smart Array Controllers support Option ROM Configuration for Arrays (ORCA) on HP
Integrity servers. When a server is powered on, the Power-On Self Test (POST) runs, and array
controllers in the system are initialized.
If the array controller supports ORCA, POST temporarily halts, and an ORCA prompt message
appears for approximately five seconds.
If ORCA is not supported, the prompt message does not appear, and the system continues with
the startup sequence.
While the ORCA prompt is displayed, press F8 to start ORCA. The ORCA main menu appears,
enabling you to create, view, or delete a logical drive.
