You can use Volume Shredder to shred both open-systems and mainframe systems, including logical devices (LDEVs) and custom volumes (CVs) of all emulation types. External volumes and Dynamic Provisioning virtual volumes* can also be shredded.

*When a shredding operation is performed on an unused virtual volume for Dynamic Provisioning, no dummy data is written to the volume.

You cannot use Volume Shredder to shred the following types of volumes:

• Pool volumes
• Virtual volumes for Thin Image
• Journal volumes
• Volumes that are not write-enabled (access attribute is not read/write)
• TSE-VOL (VSP G1000 and G1500, and VSP F1500)
• Virtual volume with ALU attribute
• Volumes in which accelerated compression is enabled
• Virtual volumes in which the capacity saving function is enabled
• Deduplication system data volumes
