Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access for P9000 and XP A.11.00

/etc/cmcluster/hrdb_sc/hrdb_sc.config
2. Edit the hrdb_sc.config file and specify the following:
• Name for the package_name attribute - package_name hrdb_sc
• Names of the nodes explicitly using the node_name attribute.
• The Site Controller Package directory for the dts/dts/dts_pkg_dir attribute
—dts/dts/dts_pkg_dir /etc/cmcluster/hrdb_sc
This is the package directory for this Site Controller Package. The Metrocluster environment
file is automatically generated for this package in this directory.
• Specify a name for the log file —
script_log_file /etc/cmcluster/hrdb_sc/hrdb_sc.log
• Specify the sites without any packages
Do not specify any packages using the critical_package or managed_package
attributes.
site site1
site site2
• Edit the following Metrocluster 3DC parameters:
◦ 3DC_TOPOLOGY
◦ DC1_NODE_LIST
◦ DC2_NODE_LIST
◦ DC3_NODE_LIST
◦ DC1_DC2_DEVICE_GROUP
◦ DC2_DC3_DEVICE_GROUP
◦ DC1_DC3_DEVICE_GROUP
◦ DC1_DC2_DEVICE_GROUP_MU
◦ DC2_DC3_DEVICE_GROUP_MU
◦ DC1_DC3_DEVICE_GROUP_MU
◦ FENCE
◦ HORCMPERM
◦ HORCMINST
The Device Group Monitor can also be configured in this Site Controller package. For
more information on the 3DC parameters and Device Group Monitor configuration, see
“Configuring Primary Packages in the Primary Cluster using the 3DC Modules ” (page 120).
3. Apply the empty Site Controller Package configuration file in the recovery cluster.
# cmapplyconf -P /etc/cmcluster/hrdb_sc/hrdb_sc.config
IMPORTANT: Ensure there are no packages configured with the critical_package or
managed_package attributes in the Site Controller Package configuration file. These attributes
must be configured only after configuring the Site Safety Latch dependencies as described in the
section “Configure Site Safety Latch Dependencies for a RAC database in the recovery cluster” of
