Nonstop Volume Level Encryption Guide

1. STOP the path performing the key rotation.
2. INITIALIZE the disk that was performing the key rotation with NEWENCRYPTKEY.
3. START the disk to revive it.
Encrypting disk data with REVIVE key rotation
This section describes how to encrypt data on mirrored disks by initializing and reviving the disk.
Overview
To encrypt a mirrored disk volume, use SCF DISK INITIALIZE and START commands, as shown in
Figure 4:
1. Stop the mirror disk.
2. Set the mirror disk to be encrypted using the INITIALIZE command. This removes any data on
the mirror disk.
3. Start the disk to revive it. This copies data from the primary to the mirror and encrypts it. During
the revive operation only the primary disk is up.
4. After the mirror disk revive completes, repeat the process for the primary disk. Both the primary
and mirror are now encrypted.
