Hitachi AMS 2000 Family Copy-on-Write SnapShot User Guide
The following sub-sections describe necessary set up procedures for
CCI for SnapShot.
The Command Device is a dedicated logical volume on the array that
functions as the interface to CCI software.
Prerequisite
The Command Device must be defined in the HORCM_CMD section
of the configuration definition file for the CCI instance on the
attached host. Up to 128 Command Devices can be designated for
the array.
The command device(s) and LU mapping setting use Navigator 2.
NOTE: When pair operation using CCI, the P-VOL and V-VOL, whose
mapping information is not set for the port that has been set in the
configuration definition file, cannot be paired. When you do not want
them recognized by a host, map to a port that is not connected to
the host or to a host group in which no host has been registered
using LUN Manager.
To set up a command device(s)
1. From the command prompt, register the array to which you want
to set the command device. Connect to the array.
2. Execute the aucmddev command to set a command device. First,
display LUs to be assignable command device, and later set a
command device. When you want to use the protection function
of CCI, enter enable following the -dev option.
The following example specifies LU 200 for command device 1.

3. Execute the aucmddev command to verify that the command
device has been set. For example:
