useful for differentiation when creating multiple volumes. Reflect a
label to the storage system is checked by default so that naming
is consistent between XP7 Command View AE and the storage

About shredding volume data
Before deleting a volume that you no longer need, completely remove the data from the volume to
avoid unauthorized use of information. The data can be removed by shredding or reformatting the
volume.
Volume data is shredded by overwriting it repeatedly with dummy data, which securely destroys the
original data. Some volumes, such as basic volumes and THP/Smart volumes that are allocated to
hosts or used for replication, cannot be shredded.
CAUTION:
You cannot restore data after it is shredded.
Some storage systems do not support the shredding functionality. For those storage systems, delete
volume information by reformatting the volumes.
