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 main ACU menu.
Caution:
!
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 main ACU 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.
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 page 89) instead, or clear it using Adaptec Storage Manager—both options take much
less time than the secure erase option.
To begin a secure erase, 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.
Stopping a Secure Erase
To stop a secure erase in progress:
In the main ACU window, select Secure Erase.
1
Select the disk drive being secure erased, then press Ctrl+Q.
2
The secure erase stops and the ACU returns to its main window.

Using the ACU to Create and Manage JBODs

To open the ACU, start the ARC utility (see
your controller, then press Enter. Select Array Configuration Utility, then press Enter.
Appendix C: Using the Adaptec RAID Configuration Utility
Description
The duration of inactive state of the array/drive after which it is powered
off. This is an optional setting.
Note:
Power Off Drive After duration should be greater than Slow
Down Drive After Duration.
The regular time interval at which the system performs a health check of
the array/drive.
Do not initialize a disk drive that is part of an array. Initializing a disk drive that's
