Creating/editing the configuration definition file
The configuration definition file is a text file that is created and edited using any standard text
editor (for example, UNIX vi editor, Windows Notepad). The configuration definition file defines
correspondences between the server and the volumes used by the server. There is a configuration
definition file for each host server. When the RAID Manager software starts up, it refers to the
definitions in the configuration definition file.
The configuration definition file defines the devices in copy pairs, including Business Copy, Business
Copy Z, Continuous Access Synchronous, Continuous Access Synchronous Z, Snapshot, Continuous
Access Journal, and Continuous Access Journal Z pairs, and is used for host management of the
copy pairs. Business Copy, Business Copy Z, and Snapshot use the same configuration files and
commands, and the RAID storage system determines the type of copy pair based on the S-VOL
characteristics. And the RAID storage system determines whether it is a Fast Snap pair or a Snapshot
pair based on the type of the pool to be used.
There are following sections in the configuration definition file:
•
HORCM_MON: Defines information about the local host.
•
HORCM_CMD: Defines information about the command (CMD) devices.
•
HORCM_DEV or HORCM_LDEV: Defines information about the copy pairs.
•
HORM_INST: Defines information about the remote host.
•
HORCM_LDEVG: Defines information about the device group.
A sample configuration definition file, HORCM_CONF (/HORCM/etc/horcm.conf), is included
with the RAID Manager software. This file should be used as the basis for creating your configuration
definition file(s). The system administrator should make a copy of the sample file, set the necessary
parameters in the copied file, and place the file in the proper directory.
The following table lists the parameters defined in the configuration file and specifies the default
value, type, and limit for each parameter. For details about parameters in the configuration file,
see the manual HP XP7 RAID Manager User Guide. See
“Sample configuration definition files”
(page 57) for detailed descriptions of configuration definition files for sample RAID Manager
configurations.
