Type the highlighted number of the menu item, or use the Up Arrow (↑) or Down Arrow (↓) key to highlight your choice; then, press Enter. You can also press Esc to return to the previous menu, the previous work area of a screen, or to the beginning of the Main Menu. If you are not familiar with the ServeRAID Configuration program, review the information in "ServeRAID menus, screens, and drive states" on page 83. Creating disk arrays: The ServeRAID controller on the system board supports up to eight independent arrays. You must use the EZ-RAID configuration feature or the Create/Delete/Copy Log Drive menu to configure the disk arrays before you partition the hard disk drives and install the operating system. The EZ-RAID configuration feature provides an easy way for you to quickly configure the disk arrays. This feature automatically creates a disk array, based on the number of RDY physical drives in the system. The EZ-RAID feature defines, initializes, and synchronizes the logical drive for you. If four or more RDY physical drives are available, this feature also will define a hot-spare drive. (See "Using the EZ-RAID configuration feature" for more information.) The Create/Delete/Copy Log Drive menu enables you to configure the arrays manually. You can use this menu to select the physical drives that you want to include in the disk arrays. You also can use this menu to define the logical and hot-spare drives for the arrays. (See "Creating disk arrays manually" on page 104 for more information.) For Advanced Users If you want to change the stripe-unit size to maximize performance, see to "Changing the RAID parameters" on page 118. Using the EZ-RAID configuration feature: The EZ-RAID configuration feature groups up to eight ready (RDY) drives into one disk array and defines one logical drive. The size of the logical drive depends on the amount of free space available, and the RAID level assigned to the logical drive depends on the number of physical drives available. The following table provides information about how EZ-RAID configuration defines a logical drive, based on the number of ready (RDY) drives available. 102 Netfinity Server HMM

Creating disk arrays:
The ServeRAID controller on
the system board supports up to eight independent arrays.
You must use the EZ-RAID configuration feature or the
Create/Delete/Copy Log Drive menu to configure the disk
arrays
before
you partition the hard disk drives and install
the operating system.
The EZ-RAID configuration feature provides an easy way
for you to quickly configure the disk arrays.
This feature
automatically creates a disk array, based on the number of
RDY physical drives in the system.
The EZ-RAID feature
defines, initializes, and synchronizes the logical drive for
you.
If four or more RDY physical drives are available, this
feature also will define a hot-spare drive.
(See “Using the
EZ-RAID configuration feature” for more information.)
The Create/Delete/Copy Log Drive menu enables you to
configure the arrays manually.
You can use this menu to
select the physical drives that you want to include in the
disk arrays.
You also can use this menu to define the
logical and hot-spare drives for the arrays.
(See “Creating
disk arrays manually” on page
104 for more information.)
For Advanced Users
If you want to change the stripe-unit size to maximize
performance, see to “Changing the RAID parameters”
on page
118.
Using the EZ-RAID configuration feature:
The
EZ-RAID configuration feature groups up to eight ready
(RDY) drives into one disk array and defines one logical
drive.
The size of the logical drive depends on the amount
of free space available, and the RAID level assigned to the
logical drive depends on the number of physical drives
available.
The following table provides information about how
EZ-RAID configuration defines a logical drive, based on
the number of ready (RDY) drives available.
