Initializing Disk Drives
If a disk drive appears grayed-out (unavailable for use in a new array), it may need to be initialized.
To begin initializing a disk drive, select Initialize Drives from the Logical Device Configuration menu. You
can initialize one drive or multiple drives. If an error occurs during initialization, the message “Initializing
drives...FAILED x of n” is displayed. Press
Enter
to see a list of drives that failed to initialize. Press
Esc
to
continue.
Caution: Do not initialize a disk drive that is part of an array. Initializing a disk drive that's
part of an array may make the array unusable. Back up all data from your disk drive before
you initialize it.
C.2.4
Rescanning Disk Drives
To begin rescanning a disk drive, select Rescan Drives from the Logical Device Configuration menu.
C.2.5
Secure Erasing Disk Drives
When you perform a secure erase on a disk drive, all data on that disk drive is completely and irretrievably
eradicated. Secure erase performs three distinct writing passes to the disk drive being erased—it does not
just write zeros.
Performing a secure erase takes up to six times longer than clearing (or zeroing) a disk drive; on a 2TB or
3TB drive, often it takes hours, possibly as long as a day! You may want to perform a secure erase only on
disk drives that contain confidential or classified information.
Note: To erase (or zero) a disk drive with non-classified information, you may choose to
format it (see
Formatting and Verifying Disk Drivesformatting disk drivesverifying disk
drivesdisk drives formattingdisk drives verifying
) instead, or initialize it using maxView
Storage Manager—both options take much less time than the secure erase option.
To begin a secure erase, select Secure Erase from the Logical Device Configuration menu, then select
Y
(yes). To return to the main Logical Device Configuration menu once the secure erase has begun, press
Esc
.
Note: For newer SATA drives, you can choose to perform a Secure ATA Erase, which
implements the secure erase feature at the drive firmware level. To start a Secure ATA
Erase, select a SATA drive, then type
Ctrl-S
to open the Secure ATA Erase dialog. You
will see this dialog only if the drive supports Secure ATA Erase.
The selected disk drive(s) cannot be used until the erase is complete.
