LDEVs.
Use the following process to set up for data encryption and enable data encryption on parity
groups:
1. Back up the secondary data encryption license key.
For more information about backing up secondary keys, see “Workflow for backing up
secondary data encryption license keys” (page 18) .
2. Block the LDEVs at the parity-group level. Do one of the following:
•
Block the LDEV using a file on the RWC computer.
For more information about blocking LDEVs using a file, see “Blocking LDEVs using a file”
(page 24) .
