Notes
1. Hard disk drive capacities influence the way
you create arrays. Drives in the array can
be of different capacities, but the ServeRAID
controller treats them as if they all have the
capacity of the
smallest disk drive. (See
“Hard disk drive capacities” on page 81 for
more information.)
2. If you change your mind after selecting the
drives for an array, you can delete the array
(by selecting Delete Disk Array from the
Create/Delete Copy Log Drive menu); then,
begin again.
5. After you select all of the drives that you want to
include in the array, press Esc to return to the
Create/Delete Copy Log Drive menu.
Note
When the stripe-unit size is 8 K (the default
setting) or 16 K (a manual setting), the maximum
number of physical drives in an array is 16.
When the stripe-unit size is 32 K or 64 K (both are
manual settings), the maximum number of
physical drives in an array is eight.
6. If you want to create another array, return to step 3
on page 104. Otherwise, continue with step 7.
7. You must define at least one logical drive for each
new array. Continue with “Defining logical drives.”
Defining logical drives:
You must define at least one
logical drive for each array. The ServeRAID controller
supports up to eight logical drives. If you have only one
array, you can define it as a single logical drive, or you can
divide it into several logical drives. If you have two or
more arrays, each array can be one logical drive, or you
can divide each array into multiple logical drives, as long
as the total number of logical drives for all of the arrays
does not exceed eight.
Note
Refer to the documentation provided with the
operating system for information about the
recommended logical drive size.
To define a logical drive:
1. Select Define Logical Drive from the
Create/Delete/Copy Log Drive menu; then, press
Enter.
2. Use the Up Arrow (
↑
) or Down Arrow (
↓
) key to
highlight the array for which you want to define a
logical drive; then, press Enter.
