By using the CCI, you can completely erase all data from volumes. After the erase, the volumes can be reused securely.
Data cannot be restored after the shredding. Therefore, before executing the command, make sure that the specified volumes are correct.
You can prevent data leakage by shredding volumes in the following cases:
- When you want to reuse a volume.
- When you want to dispose of a drive.
Shredding erases the volume data by overwriting it repeatedly with dummy data.
Operation overview
Block the target volume, and then delete the data.
- Block the volume.
To stop access to the target volume, block the volume. To prevent operation mistakes, data can be erased only when the volume is blocked.
- Erase the data from the volume.
Delete data from the volume by repeatedly overwriting the unnecessary dummy data. You can specify any data pattern for the second time. By default, the dummy data is overwritten in the following order:
-
First time: 0x00000000
-
Second time: 0xFFFFFFFF
-
Third time: 0x00000000
