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 Conguration 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.

Rescanning Disk Drives

To begin rescanning a disk drive, select Rescan Drives from the Logical Device Conguration menu.

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 condential or classied information.

Note: To erase (or zero) a disk drive with non-classied information, you may choose

to format it (see Formatting and Verifying Disk Drives on page 92) 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 Conguration menu, then select

Y (yes). To return to the main Logical Device Conguration 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 rmware 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.

Stopping a Secure Erase

To stop a secure erase in progress:

1. In the Logical Device Conguration menu, select Secure Erase.

2. Select the disk drive being secure erased, then press Ctrl+Q.

The secure erase stops and you return to the main Logical Device Conguration menu.
