This subsection provides information on copy pair operations.
Table 9-3 lists items to consider before creating copy pairs.
Table 9-3 Items to Consider Before Creating Copy Pairs
Item Description
Existing copy pair A copy pair can be created by using storage subsystem management tools such as Remote
Web Console and SVP. However, there is no HORCM configuration file created for RAID
Manager control for the copy pair created by the above management tools. Therefore, the
status of the copy pair cannot be changed or deleted by using the Device Manager server. To
change or delete the status of a copy pair by using the Device Manager server, delete the copy
pair by using the appropriate management tool, and then create the copy pair again by using
the Device Manager server.
HORCM configuration file
(horcm.conf) For Windows, store the configuration definition file for RAID Manager in the system directory.
For UNIX, store the file in the /etc directory.
If the environment variable is specified and the HORCM configuration file is stored in a location
other than the one specified above, the HORCM configuration file cannot be managed by the
Device Manager server.
The Windows
® system directory can be checked by using the echo "%SystemRoot%"
command.
It might take some time to add a storage subsystem or refresh operations when both of the
following conditions are satisfied:
• Device Manager agent and RAID Manager are installed on the host that the Device
Manager server recognizes.
• There is an unused HORCM configuration file on the host, or a lot of unused copy pairs are
defined in the HORCM configuration file.
In such a case, disable the unused HORCM configuration file or the unused copy pair
definitions in the HORCM configuration file, by using the following methods:
• Disabling an unnecessary HORCM configuration file
Set the instance number of the unused HORCM configuration file to the Device Manager
agent's property server.agent.rm.exclusion.instance, stop the Device Manager
agent, and then restart the Device Manager agent.
• Disabling an unused copy pair definitions in the HORCMconfiguration file
Delete the unused copy pair definition in the HORCMconfiguration file, or make the
definition a comment line.
