Compaq recommends that you designate a spare drive for your array.
This online spare, or “hot spare,” is automatically used immediately
when one of the other member drives in the array fails. When a failure is
detected, the array controller uses parity information to rebuild the
information that was on the failed drive. After the rebuilding process,
the array resumes its fault-tolerant state. If you do not have a spare drive
for your array and a drive fails, you are unable to begin rebuilding until
you physically replace the failed drive. Until the drive is replaced and
the rebuild process is complete, the array is not fault tolerant. If another
drive fails at this time, data loss is probable. To select a spare drive, use
the spare drive icon located at the bottom of the screen and add the drive
to the array set. Spares can be shared among arrays.

You have now completed your array configuration. Once complete, you
must create a logical drive before exiting or the new array will not be
saved. Use the procedure in the next section to create a logical drive or
drives from your arrays.
Creating Logical Drives from Arrays
Now that you have gathered your physical drives into fault-tolerant arrays, you
need to create logical drives from them. You can choose to create one large
logical drive using the entire space of the array, or you may want to divide
each physical drive into two or more logical drives. Compaq recommends that
you create one logical drive from the array. You can add physical drives to the
array later.
