System configuration using CCI
This section describes system configurations using the in-band method or
out-of-band method. In addition, a system configuration for connecting to an
in-band CCI server by using the out-of-band method is also described. For an
overview of the in-band and out-of-band methods, see Command execution
by the in-band and out-of-band methods on page 1-5 .
In-band system configurations and out-of-band system
configurations
Values to specify for HORCM_CMD in the configuration definition file are
different between in-band and out-of-band method system configurations.
• In-band method. This method specifies the device special file of
command device in the configuration definition file. For details about
contents to specify for HORCM_CMD, see HORCM_CMD (in-band method)
on page 2-17 .
• Out-of-band method. This method specifies the SVP for creating virtual
command devices or IP addresses of GUM in the command definition file.
For details about contents to specify for HORCM_CMD, see HORCM_CMD
(out-of-band method) on page 2-21 .
The location of the virtual command device depends on the type of storage
system. The following table lists the storage system types and indicates the
allowable locations of the virtual command device.

CCI on the SVP must be configured as a CCI server in advance.
The following figures show a system configuration example and a setting
example of a command device and a virtual command device using the in-
band and out-of-band methods.
Note: For the out-of-band method using the maintenance utility (GUM) of
VSP Gx00 models and VSP Fx00 models, the command might time out if a
controller with GUM is maintained. Before the maintenance, change command
devices so that you use a virtual command device of the other GUM. For
details about how to switch command devices, see Alternate command device
function on page 2-5 .
