system in In-Band method can be connected in Out-of-Band method. If a CCI
server is specified as a virtual command device, it provides better
performance than the Out-of-Band method with specified SVP/GUM as a
virtual command device.

Hardware requirements

CCI uses SCSI path through driver to issue I/O for command device. To use
CCI server port as virtual command device, the virtual command device
interface needs to be converted to the actual SCSI path through interface.
Following is the environment for using CCI server port as a virtual command
device.
• CCI server which can set virtual command devices
CCI support platform except Tru64UNIX and the environment can be used
SCSI path through driver
• Client PC which can issue commands to virtual command devices
It must be CCI support platform.
• Initiator port
Initiator port is required on the following storage systems: Virtual Storage
Platform, Unified Storage VM, Virtual Storage Platform G1000, Virtual
Storage Platform G1500, and Virtual Storage Platform F1500.
Following is the default port number.
If not specified the instance number: 34000
If specified instance number (X): 34000 + X + 1
If you change the default port number, use following environment
variables.
$HORCM_IPSCPORT=<services>*
* <services>: port number or service name
For details about supported platforms, see the Command Control Interface
Installation and Configuration Guide.
I/O Traffic Control
Synchronized I/O is issued from a virtual command device. The queueing
time might occur because of the heavy I/O traffic because the virtual
command device has to relay the command to the next virtual command
device in the cascade configuration using the virtual command device. To
improve the response in this environment, define the configuration so that
asynchronous I/O is issued using the following environment variables.
$HORCM_IPSCPAIO=1

Security setting

Following security can be set.
• Specifying security of IP address and port number
By defining IP address and port number of the client PC that issues
command to virtual command device to HORCM_ALLOW_INST in the
3-6
CCI functions
