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
for assistance.

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
