1 XP Data Shredder for the XP128/XP1024/XP10000/XP12000 If you change the user for a volume, you should delete data stored by the previous user for security purposes. The Data Shredder feature deletes data on volumes and prevents deleted data from being restored. Shredding operation refers to the process of deleting all data on a volume by overwriting it with dummy data. Data Shredder is based on DoD5220.22-M, which is the standard defined by the U.S. Department of Defense.
By default, Data Shredder overwrites volumes with dummy data three times. You can change the default and overwrite the volume up to eight times. For more information, see ”Defining Shredding operation settings” on page 14. Target volumes for Shredding operations You can use the Shredding operation for any type of volume (for example, VDEV, LDEV, or custom volume) and emulation type, but the status of the volume must be Blocked.
Shredding Param pane Use this pane to define settings for Shredding operations. To open this pane, click Shredding Param (Parameter) on the Customized Volume pane. Figure 3 Shredding Param pane The Shredding Param pane contains the following: • Write Data Type: Settings for Shredding operations. • Default (00-FF-00): If selected, defaults are used for Shredding operations. Data on a volume is deleted by overwriting the volume with dummy data three times.
If you select Define in the Write Data field, and click Set without entering anything in the text box, an error message appears. The Set button is not available when you select Default in the Write Data Type field. • Delete: Deletes the selected row in the Format List field. If you select a row with Last Data, and click Delete, an error message appears. The Delete button is not available when you select Default in the Write Data Type field.
Shredding Data Output pane When you specify volumes in the Shredding Data Output pane during a Shredding operation, the results of the operation are saved in files. Figure 4 Shredding Data Output pane The Shredding Data Output pane contains the following: • non-object Volume Results of shredding volumes in this list are not saved in files. • object Volume Results of shredding volumes in this list are saved in files. Each row represents one volume.
NOTE: When you change the status of a volume to Blocked, I/O operations cannot be performed on the volume. By specifying write permissions, you can limit who is allowed to perform shredding operations. 1. In the Command View XP or XP Remote Web Console main pane, change to Modify mode by clicking the button ( ). A message pane appears asking if you want to change the mode. 2. Click OK. The operation mode changes. 3. In the Volume Management pane, click LDEV Status.
NOTE: To delete a row from the Format List, select the row, and click Delete. You cannot delete the row defined as Last Data. Deleting data on volumes (Shredding) You can perform the Shredding operation on any given volume as many times and as often as you want. 1. In the Volume Management pane, check the LDEV Information table, and verify that the status of the target volume is Blocked. NOTE: If the status of the volume is not shown in the LDEV Information table, click LDEV Status.
