4.22 Controlling Volume Migration
The volume migration including the external volume will be required to control using CLI in
Data Lifecycle Management (DLCM) solution. It is possible to support the volume migration
that cooperates with CC (Cruising Copy) and the external connection by operating the
current ShadowImage and VDEV mapping of the external connection.
Also, it is important to consider the support of CC (Cruising Copy) on the compatibility based
on the current CLI interface, because CCI is supporting ShadowImage and the external
connection. For this purpose, CCI makes the CLI interface that works by minimum
compatible of the APP by specifying the COPY mode for CC (Cruising Copy) to the CLI of CCI.
4.22.1 Specifications for Volume Migration
CCI is necessary to be mapped to the port for pooling of RAID in order to control the volume
of the external connection. So the external volume need to be mapped previously to the
port of RAID without connecting to the host. The following is the execution example of the
volume migration executed for LDEV#18.
