Device considerations
For Linux on Z and LinuxONE, you can apply the infrastructure for protected volume encryption on block devices (for example, on DASD devices or on SCSI-over-FCP attached devices).
For DASDs, use partitions for disk encryption only. For volumes attached through SCSI-over-FCP, you can either use partitions or the full block device.
For more information on SCSI devices, read How to use FC-attached SCSI devices with Linux on System z.
