Defining The Configuration Definition File - Hitachi AMS 2000 User Manual

Defining the configuration definition file

The configuration definition file describes system configuration. It is
required to make CCI operational. The configuration definition file is a text
file created and/or edited using any standard text editor. It can be defined
from the PC where CCI software is installed.
A sample configuration definition file, HORCM_CONF, is included with the
CCI software. It should be used as the basis for creating your configuration
definition file(s). The system administrator should copy the sample file, set
the necessary parameters in the copied file, and place the copied file in the
proper directory. For more information on configuration definition file, refer
to the Hitachi Adaptable Modular Storage Command Control Interface (CCI)
User's Guide.
The configuration definition file can be automatically created using the
mkconf command tool. For more information on the mkconf command, refer
to the Hitachi Adaptable Modular Storage Command Control Interface (CCI)
Reference Guide. However, the parameters, such as poll(10ms) must be set
manually (see Step
To define the configuration definition file
The following example defines the configuration definition file with two
instances on the same Windows host.
1. On the host where CCI is installed, verify that CCI is not running. If CCI
is running, shut it down using the horcmshutdown command.
2. From the command prompt, make two copies of the sample file
(horcm.conf). For example:
•
c:\HORCM\etc> copy \HORCM\etc\horcm.conf
\WINDOWS\horcm0.conf
c:\HORCM\etc> copy \HORCM\etc\horcm.conf
\WINDOWS\horcm1.conf
3. Open horcm0.conf using the text editor.
4. In the HORCM_MON section, set the necessary parameters.
Important: A value more than or equal to 6000 must be set for
poll(10ms). Specifying the value incorrectly may cause resource
contention in the internal process, resulting the process temporarily
suspending and pausing the internal processing of the array.
5. In the HORCM_CMD section, specify the physical drive (command
device) on the array.
