Understanding shredding results in compressed files
When you open the compressed file, you see binary and text files that contain shredding results.
•
The name of the binary file indicates LDKC, CU, and LDEV numbers of the shredded volumes,
and the number of times the system wrote dummy data to the volumes. For example, if a binary
file is named 00-01-11-03.bin, the LDKC number is 00, the CU number is 01, and the
LDEV number is 11. The filename also indicates that the system wrote dummy data to that
volume three times. A binary file contains the first 512 bytes of data of a shredded volume
(LDEV).
•
The file name of a text file appears as follows:
shred_finish-time-of-shredding-operation.txt
The compressed file is saved with the time zone setting of the SVP. If the compressed file is
decompressed on the Remote Web Console computer, the time stamp of the decompressed file
appears with the time zone setting of the Remote Web Console computer. The time stamp of the
decompressed file might be different from the actual finish time of the shredding operation.
The text file contains the following summary information:
•
Results of the shredding operation (see “Viewing shredding status with the Logical Device
window” (page 13)
•
Contents of the dummy data
•
Shredded volumes
•
Start and finish time of the shredding operation
