F2

Display drive information for the highlighted drive.

F3

Display the logical drives that have been configured.

F4

Designate the highlighted drive as a hot spare.

3. Press the arrow keys to highlight specific physical drives. Press the spacebar to associate the

highlighted physical drive with the current array. The indicator for the selected drive changes
from READY to ONLIN A [array number]-[drive number]. For example, ONLIN A2-3
means disk drive 3 in array 2.

Add physical drives to the current array as needed. Try to use drives of the same capacity in a
specific array. If you use drives with different capacities in an array, all the drives in the array
are treated as though they have the capacity of the smallest drive in the array.

The number of physical drives in a specific array determines the RAID levels that can be
implemented with the array.

4. Press Enter when you are finished creating the current array. The logical drive configuration

screen appears.

The window at the top of the screen shows the logical drive that is currently being configured
as well as any existing logical drives. The column headings are:

LD

The logical drive number

RAID

The RAID level

Size

The logical drive size

#Stripes

The number of stripes (physical drives) in the associated
physical array

StrpSz

The stripe size

Drive-State

The state of the logical drive

5. Set the RAID level for the logical drive. Highlight RAID and press Enter. The available

RAID levels for the current logical drive are displayed. Select a RAID level and press Enter
to confirm.

6. Set the stripe size, cache write policy, Read policy, and I/O (cache) policy from the

Advanced Menu.

Stripe size: This parameter sets the Stripe Size. The default setting is 8 K.

Write policy: This parameter specifies the cache write policy. You can set the write policy to
Write-Back or Write-Through. The default setting is WRTHRU.

Read-Ahead: This parameter enables the SCSI Read-Ahead feature for the logical drive.
You can set this parameter to Normal, Read-Ahead, or Adaptive. The default setting is
Adaptive Read-Ahead. (See glossary for definitions.)

Cache policy: This parameter specifies read cache mode during data transfers involving the
current logical drive. The default setting is Cached I/O.

Press Esc to exit the Advanced Menu.

7. When you are finished defining the current logical drive, highlight Accept and press Enter.

The array selection screen appears if there are any unconfigured disk drives left.

8. Repeat steps 3 through 7 to configure another array and logical drive. HP NetRAID supports

up to eight logical drives per adapter. If you are finished configuring logical drives, press Esc
to exit Easy Configuration. A list of the currently configured logical drives appears.

After you respond to the Save prompt, you will return to the Configure menu.

9. Initialize the logical drives you have just configured. See Initializing logical drives below.
