Use CCI to run commands through an in-band connection to perform Thin Image Advanced tasks. To run the command through an in-band connection, reserve a volume for use as a command device.
If you use CCI to run commands through an out-of-band connection, you do not need to reserve a volume.
CAUTION:
For maximum host I/O performance, use
CCI to run commands through an in-band connection.
For more information about reserving a volume for use as a command device, see the Command Control Interface User and Reference Guide.
