Utilities 29

CAUTION: Do not use this utility if there are any IO Accelerator devices installed in the system

that are not selected to be cleared or purged of data.

• Ensure that you back up any data prior to activation of this utility.

• Remove any devices that are not targeted for purge.

• After the data is removed from the target devices, it is purged.

• There is no recovery to this action.

CAUTION: If the device is in Read-only mode, perform a format using fio-format before

running fio-sure-erase.

The fio-sure-erase utility cannot erase the device if it is in Minimal mode. Updating the

firmware might move the device out of Minimal Mode. If the device remains in Minimal mode,

contact HP Support (http://www.hp.com/support) for assistance.

IMPORTANT: Prior to reactivating the device, format the device with fio-format after running

fio-sure-erase

To run fio-sure-erase, the block device must be detached. For more information, see "fio-detach (on

page 24)."

Description

The fio-sure-erase is a command-line utility that securely removes data from IO Accelerator devices. It

complies with the Clear and Purge level of destruction from the following standards:

• DOD 5220.22-M—Complies with instructions for Flash EPROM.

• NIST SP800-88—Complies with instructions for Flash EPROM.

For more information, see the following sections on "Clear support" and "Purge support."

Syntax

fio-sure-erase [options] <device>

where <device> is the name of the device node (/dev/fctx), where x indicates the card number: 0, 1,

2, and so on. For example, /dev/fct0 indicates the first IO Accelerator device installed on the system. To

view this device node, use "fio-status (on page 26)."

IMPORTANT: Products with Multiple Devices

fio-sure-erase applies to individual IO Accelerator devices. For example, if you are

planning to purge an ioDrive Duo device, perform this operation on each of the two IO

Accelerator devices.

Options Description

-p

Purge instead of Clear: performs a write followed by an erase. For more information,

see "Purge support."

-y

No confirmation: Does not require a yes/no response to execute the utility.

-q

Quiet: Does not display the status bar.

IMPORTANT: If fio-sure-erase

is run without options, then a Clear is performed. For more

information, see "Clear support."

Each block of memory consists of uniform 1 bits or 0 bits.
