7.3.5 Initializing a Logical RAID Drive
You must initialize a logical RAID drive before you can use it to ensure
consistent RAID parity information. The utility initializes the logical RAID drive
by writing a pattern of zeros to it. This creates a starting parity for a logical
RAID drive with parity, or starting data for a logical RAID drive which does not
have parity.
CAUTION
Do not initialize a logical RAID drive if it has valid
data. Initialization overwrites and destroys all
data.
Also, after you initialize a logical RAID drive, do
not change or rearrange the physical drives or
cables. Otherwise, all data in the drive group can
be lost.
To initialize a logical RAID drive, follow these steps.
1. From the main menu, select the Initialize Logical Drive option menu and
press the Enter key. The utility displays the Initialize Logical Drive screen,
with each logical RAID drive that you created, similar to the screen shown
in Figure 7–20.
