Setting up a Smart Array 6402 Controller As a Boot Device
The Smart Array 6402 Controller can be set up as a boot device.
NOTE
For PA-RISC systems, use Ignite/UX and
saconfig
to create the logical drives. For Integrity
systems, use the Option ROM Configuration for Arrays (ORCA) to create the logical drives.
Array Configuration Limitations
For the most efficient use of drive space, do not mix drives of different capacities within the same array. The
configuration utility treats all physical drives in an array as if they have the same capacity as the smallest
drive in the array. The excess capacity of any larger drives is wasted because it is unavailable for data
storage.
The probability that an array will experience a drive failure increases with the number of physical drives in
the array. If you configure a logical drive with RAID 5, keep the probability of failure low by using no more
than 14 physical drives in the array.
Offline Configuration of HP-UX 11i v1 Using Ignite-UX
To set up a Smart Array 6402 Controller as a boot device, you must install HP-UX 11i v1 on one of the
controller’s logical drives. For PA systems follow this procedure:
Step 1.
Start Ignite-UX from the HP-UX 11i v1 Core OS Install and Recovery Media. The Ignite-UX
“
Welcome
” screen displays:
Welcome to Ignite-UX!
Use the <tab> key to navigate between fields, and the arrow keys
within fields.
Use the <return/enter> key to select an item.
Use the <return/enter> or <space-bar> to pop-up a choices list.
If the
menus are not clear, select the "Help" item for more information.
