Goal

Reliably erase LDEV data prior to de-comissioning storage and/or to meet US Deptartment of Defense standards.

Fix

Description
An application for reliably erasing LDEV data in a manner which meets US Department of Defense standards, was made available for the Sun StorEdge[TM] 9900V series of disk arrays.

The function of Hitachi Volume Shredder is to prevent important data from being leaked when disks are removed from the array, and taken off-site. A license key is necessary to use Hitachi Volume Shredder.

Steps to Follow
US Department of Defense standard DoD5220.22-M defines that data needs to be over-written three or more times in all storage locations, to prevent HDD data from being restored.

Hitachi Volume Shredder provides this level of security by performing multiple write operations on the magnetic disk media, in random orpre-determined patterns, to completely remove data.

When Hitachi Volume Shredder has been activated by installing a valid license key on the SVP, it functions by default, any time an LDEV is formatted.
Configuration parameters define how data is to be erased on the logical device(s) - these include the number of times a write operation is to be performed, as well as pattern and type of data to write.

To access HVS functions:

 1. Access either Web Console or Storage Navigator in Modify mode, for the array to be configured.

 2. Click on the "LUN Expansion/Virtual LVI" button, located on the left-hand toolbar. Then select the VLL Tab.

 3. Click on the "Shredding Param." button.

 4. Define the type of data to be written(hex), the write pattern, and number of writes. Note: the default is three writes - 00, FF, then 00 - which meets the DoD specification.

 5. Click "OK" to exit the configuration screen.

Volume Shredding generates a compressed .tgz file containing binary files with the results from the operation. To view the contents of the bin files, use a hex editor. If the contents are all zero's, shredding was successful. If not, this indicates the operation ended with an error.

Note that you cannot perform volume shredding on external volumes.
