Figure 111 Using Configuration Files
NOTE: Consider the following while working with configuration files:
•
Users who handle copy groups must lock the groups they are handling, to ensure that contention
will not occur.
•
When Business Continuity Manager is upgraded, any existing Business Continuity Manager
configuration files that were properly created can be read. Note that when configuration files
are saved after an upgrade is performed, the files cannot be used with the earlier version of
Business Continuity Manager.
•
If a device registered in the configuration file is reserved for a long period, a request from
Business Continuity Manager might wait for a long period. Before performing a registration
in the configuration file, verify that the value of MIH time out is appropriate.
Working with scripts
Business Continuity Manager manages the static storage system configuration using configuration
files (XML files). Using CLI commands, you can read storage system configuration information from
these XML files, and apply operation instructions simultaneously. To perform the volume operations,
you can write a script.
Expanding to REXX Variables
To operate a copy group, use the YKLOAD command to expand information about the copy groups,
device configurations, route lists, and path sets from the configuration file to REXX variables.
The YKLOAD command inputs an XML file and outputs information to the REXX variable structure
specified by the STEM parameter.
Although a single script can control multiple copy groups, information for each copy group will
be expanded and stored in a unique copy group structure.
A single execution of the YKLOAD command might expand multiple REXX variable structures.
Therefore, if you only drop certain REXX variable structures, the copy group might not be operated
correctly. If you want to correctly drop all related REXX variable structures simultaneously, use the
YKDROP
command. For details on the REXX variable structures expanded by the YKLOAD command,
see the description provided in the HP XP P9000 for Business Continuity Manager Reference Guide.
