Physical Data Replication for ContinentalClusters Using EMC SRDF
Setting up a Recovery Package on the Recovery Cluster
Chapter 7342
Setting up a Recovery Package on the
Recovery Cluster
The installation of EMC SRDF, MC/ServiceGuard, and
ContinentalClusters software is exactly the same as in the previous
section.
The procedures below will install and configure a recovery package on
the recovery cluster. Consult the MC/ServiceGuard documentation for
instructions on setting up an MC/ServiceGuard cluster (i.e., lan, VG, LV,
etc).
1. Split the EMC/SRDF logical links for the disks associated with the
application package. See the script Samples-CC/pre.cmquery for an
example of how to automate this task. The script must be edited to
refer to the SRDF groups configured and customized with the
Symmetrix device group names.
2. Use the following command to generate a cluster ASCII file:
# cmquerycl -n node1 -n node2 -C CClusterNY.ascii
Edit the file CClusterNY.ascii. Be sure to select a primary cluster
lock disk that is not a lock disk on the recovery cluster. Edits include
spreading HEARTBEAT_IP on all user LANs, and setting
MAX_PACKAGES.
3. Check the configuration with the following command:
# cmcheckconf -C CClusterNY.ascii
4. Create the cluster binary with the following command:
# cmapplyconf -C CClusterNY.ascii
5. Test the cluster using the following commands:
# cmruncl -v
# cmviewcl -v
Does the cluster come up? If so, then stop the cluster:
# cmhaltcl -f
