156 Chapter 3 Preparing for CCI Operations
Two Instances. To start up two instances of CCI on a UNIX system:
1. Modify /etc/services to register the port name/number (service) of each configuration
definition file. The port name/number must be different for each CCI instance.
horcm0 xxxxx/udp xxxxx = the port name/number for horcm0.conf
horcm1 yyyyy/udp yyyyy = the port name/number for horcm1.conf
2. If you want HORCM to start automatically each time the system starts up, add
/etc/horcmstart.sh 0 1 to the system automatic start-up file (e.g., /sbin/rc).
3. Execute the horcmstart.sh script manually to start the CCI instances:
# horcmstart.sh 0 1
4. Set an instance number to the environment which executes a command:
For B shell:
# HORCMINST=X X = instance number = 0 or 1
# export HORCMINST
For C shell:
# setenv HORCMINST X
5. Set the log directory (HORCC_LOG) in the command execution environment as needed.
6. If you want to perform Hitachi TrueCopy operations, do not set the HORCC_MRCF
environment variable. If you want to perform ShadowImage operations, set the
HORCC_MRCF environment variable for the HORCM execution environment.
For B shell:
# HORCC_MRCF=1
# export HORCC_MRCF
For C shell:
# setenv HORCC_MRCF 1
# pairdisplay -g xxxx xxxx = group name
