Physical Data Replication for ContinentalClusters Using EMC SRDF
Setting up a Recovery Package on the Recovery Cluster
Chapter 7344
<backup_pkg_name>.sh (Package monitor shell script, if
applicable)
<backup_pkg_name>_srdf.env (MC/SRDF environment file)
10. 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.
11. Apply the MC/ServiceGuard configuration using the cmapplyconf
command or SAM for the recovery cluster.
12. Test the cluster and packages as follows:
# cmruncl
# cmmodpkg -e bkpkgCCA
# cmviewcl -v
Note that cmmodpkg is used to manually start application packages.
Do all application packages start? If so, then issue the command:
# cmhaltcl -f
NOTE Application packages cannot run on R1 and R2 at the same time.
Any running package on the primary cluster that will have a
counterpart on the recovery cluster must be halted to prevent data
corruption.
13. Restore the SRDF logical links for the disks associated with the
application package. See the script Samples-CC/post.cmapply for
an example of how to automate this task. The script must be
customized with the Symmetrix device group names.
The recovery cluster is now ready for continental cluster operation.
