Using New Configuration
The New Configuration option allows you to associate logical drives with partial and/or multiple
physical arrays (the latter is called spanning of arrays).
Erases Configuration
Choose the New Configuration option to erase the existing configuration information about the
selected adapter.
To use the spanning feature and keep the existing configuration, use View/Add Configuration.
1. Choose Configure from the HP NetRAID Config Management Menu.
2. Choose New Configure from the Configure menu. An array selection window is displayed
showing the devices connected to the current adapter. Hot key information appears at the
bottom of the screen. The hot key functions are:
F2 Display the manufacturer data and the adapter error
count for the highlighted drive.
F3 Display the logical drives that have been configured.
F4 Designate the highlighted drive as a hot spare.
F10 Display the logical drive configuration screen.
Before you can press F10 to start the configuration, you must press Enter to End the Array.
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. To continue defining arrays,
repeat step 3. To begin logical drive configuration, go to step 5.
5. Press F10 to configure logical drives. 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:
◊ RAID =: Sets the RAID level
◊ Size =: Sets the logical drive size
◊ Advanced Menu: Provides access to the following options

Cache Policy =
◊ Accept: Accept or reject the new configuration
◊ Span =: Set the spanning options described below.
∗
CanSpan: Array spanning is enabled for the current logical drive. The logical drive
can occupy space in more than one array.
∗
NoSpan: Array spanning is disabled for the current logical drive. The logical drive
can occupy space in only one array.
