To Initialize Disk Drives With the ACU
If a disk drive is displayed grayed-out (unavailable for use in a new array), it may
need to be initialized.
●
Select Initialize Drives from the main ACU menu.
Caution –
Do not initialize a disk drive that is part of an array. Initializing a disk
drive that is part of an array may 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 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
“Using the Disk Utilities to Manage Disk Drives” on page 76
)
instead, or clear it using Sun StorageTek RAID Manager graphical user interface
(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 once the secure erase has begun, press Esc. The
selected disk drive(s) 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.
