Space reclamation
When a block that was provisioned is no longer needed, it can be reclaimed. The Brocade
Encryption Switch supports following methods to reclaim the provisioned blocks:
• Sending the UNMAP SCSI command
Note the following limitations:
• The Host will get garbled data while trying to read an unmapped region.
