Physical Data Replication for ContinentalClusters Using EMC SRDF
Setting up a Primary Package on the Primary Cluster
Chapter 7 341
When using ftp, be sure to make the file executable on any
destination systems.
13. Verify that each host in both clusters in the continental cluster has
the following files in the directory /etc/cmcluster/<pkg_name>:
• <pkg_name>.cntl (EMC SRDF package control script)
• <pkg_name>.conf (MC/ServiceGuard package ASCII config file)
• <pkg_name>.sh (Package monitor shell script, if applicable)
• <pkg_name>_srdf.env (MC/SRDF environment file)
14. Split the 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
customized with the Symmetrix device group names.
15. Apply the MC/ServiceGuard configuration using the cmapplyconf
command or SAM.
16. Using standard MC/ServiceGuard commands (cmruncl, cmhaltcl,
cmrunpkg, cmhaltpkg), test the primary cluster for cluster and
package startup and package failover.
17. Restore the SRDF logical links for the disks associated with the
application package. See the script Samples-CC/post.cmapply
(after recovery cluster is completed in next section) for an example of
how to automate this task. The script must be customized with the
Symmetrix device group names.
The primary cluster is now ready for Continental Cluster operation.
