This section describes the additional steps you must follow to enable your system to boot from logical drives on a Smart Array Series Controller. 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 P400 and P800 Controller for Integrity Servers Support Guide at: http://docs.hp.com/en/netcom.html
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”. 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. | | | |  | NOTE: Pressing F8 at the ORCA prompt might not start ORCA on all terminals. If ORCA does not start when you press F8, reboot the system and press the key sequence ESC 8 at the ORCA prompt to start ORCA. | | | | |
To create a logical drive using ORCA, follow these steps: Select Create Logical Drive. The screen displays a list of available (unconfigured) physical drives and the valid RAID options for the system. Use the arrow keys, space bar, and Tab key to navigate around the screen and set up the logical drive, including an online spare drive if one is required. | | | | | NOTE: You cannot use ORCA to configure a single spare drive to be shared among several arrays. To configure shared spare drives, you must use the saconfig command on the CLI. | | | | |
Press Enter to accept the settings. Press F8 to confirm the settings and save the configuration. After several seconds, the Configuration Saved screen appears. Press Enter to continue. Create another logical drive by repeating steps 1-5 if necessary.
For more information on using ORCA, see the HP Smart Array P400 and P800 Controller for Integrity Servers Support Guide at: http://docs.hp.com/en/netcom.html |
