Caution – Do not initialize a disk drive that is part of an array. Initializing a disk drive that is part of an array might make the array unusable. Back up all data from your disk drive before you initialize it.

To Rescan Disk Drives With the ACU

Select Rescan Drives from the main ACU menu.

To Perform a Secure Erase on Disk Drives With the ACU

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. You might 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 might choose to format it (see “Using the Disk Utilities to Manage Disk Drives” on page 56) instead, or clear it using Sun StorageTek RAID Manager GUI. Both options take much less time than the secure erase option.

Select Secure Erase from the main ACU menu, then select Y (yes).

To return to the main ACU menu after the secure erase has begun, press Esc. The selected disk drive or drives cannot be used until the erase is complete.

To Stop a Secure Erase in Progress With the

ACU

1.From the main ACU window, select Secure Erase.

2.Select the disk drive being secure erased, then press Ctrl-Q. The secure erase stops and the ACU returns to its main window.
