Chapter 5 Configuration To define a logical drive that does not span arrays: 1. Make sure that the Span Arrays box does not have a check mark in it; if it does, click on it to remove the check. 2. Set the RAID level by clicking the arrow and selecting the RAID level from the pull-down menu. 3. Set the logical drive size by either accepting the default in the box or by clicking in the Size box and typing a smaller size. Setting a smaller size leaves space for another logical drive on the same array. 4. Set the stripe size, read policy, write policy, or cache policy, by clicking the Advanced button to display the Advanced Parameter window. Click the arrows to view the choices, and select the ones you want. Disregard the Virtual Sizing check box, because you can change this parameter only in the HP NetRAID Express Tools utility. Click OK to return to the Logical Drive Definition window. 5. When the logical drive parameters are set, click the Accept button. The next logical drive to be defined is displayed. If there is still space in the current array, the new logical drive is on it. 6. Define any other logical drives on the current array that will not span to the next array. HP NetRAID Assistant Wizard keeps creating logical drives on the same array until its capacity is used fully, or until there are eight logical drives defined. To create a logical drive that spans two or more arrays: NOTE The arrays to be spanned must have sequential array numbers and each array must contain the same number of physical drives. HP NetRAID Assistant will attempt to span up to four arrays. Array spanning will stop when: • It has created a logical drive of the size you specify in Step 2 below. • The next sequentially numbered array has a different number of drives. (Spanned arrays must contain the same number of drives in each array.) 51

To define a logical drive that does
not
span arrays:
1.
Make sure that the Span Arrays box does not have a check mark in it; if it
does, click on it to remove the check.
2.
Set the RAID level by clicking the arrow and selecting the RAID level
from the pull-down menu.
3.
Set the logical drive size by either accepting the default in the box or by
clicking in the Size box and typing a smaller size. Setting a smaller size
leaves space for another logical drive on the same array.
4.
Set the stripe size, read policy, write policy, or cache policy, by clicking
the
Advanced
button to display the Advanced Parameter window. Click
the arrows to view the choices, and select the ones you want. Disregard
the Virtual Sizing check box, because you can change this parameter only
in the HP NetRAID Express Tools utility. Click
OK
to return to the
Logical Drive Definition window.
5.
When the logical drive parameters are set, click the
Accept
button.
The next logical drive to be defined is displayed. If there is still space in
the current array, the new logical drive is on it.
6.
Define any other logical drives on the current array that will not span to
the next array. HP NetRAID Assistant Wizard keeps creating logical
drives on the same array until its capacity is used fully, or until there are
eight logical drives defined.
To create a logical drive that spans two or more arrays:
NOTE
The arrays to be spanned must have sequential array numbers
and each array must contain the same number of physical
drives.
HP NetRAID Assistant will attempt to span up to four arrays.
Array spanning will stop when:
•
It has created a logical drive of the size you specify in
Step 2 below.
•
The next sequentially numbered array has a different
number of drives. (Spanned arrays must contain the same
number of drives in each array.)
