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 DP volumes...

Note: Shred during off hours, such as overnight, so that the shredding
process does not adversely affect system performance. To verify the
standard required times for shredding, see the  Hitachi Volume Shredder
User Guide .
4.In the  Shred Volumes  dialog box, check the target volume to be
shredded and edit the writing data pattern, if needed.
If the storage system does not support shredding, the data will be

If the capacity of the LUSE volumes or basic volumes that have already been
allocated to hosts becomes insufficient, you can increase capacity by adding unallocated volumes or creating LUSE volumes.
LUSE volumes are created by using volumes that belong to the same
resource group, have the same drive type, and are at the same RAID level.
When using FMD/SSD flash drives in a Virtual Storage Platform or HUS VM
storage system, you can still create a LUSE volume even if the drive types
are different.
Note:...

• External volumes can be allocated to hosts the same as internal volumesare.
• Important data on internal volumes can be backed up to external volumes.
• Infrequently accessed data on internal volumes can be moved to external volumes for archiving.
You can virtualize volumes in two ways:
• Virtualizing volumes: In HCS, external volumes are mapped by specifying the external storage
system, internal storage system, external volumes, and number of
external paths. Although HCS manages only registered...
