in the Site Controller's package directory on the node where the Site Controller package is

running, and then executing the cmhaltpkg command:

# cd <site_controller_pkg_dir>

# touch DETACH

# cmhaltpkg <site_controller_package_name>

2. Steps on the recovery site where the complex workload packages are not running as follows:

a. Take a backup of the application package configurations and delete the application

packages managed by the Site Controller on the recovery site. After this step is complete,

there are no dependents on the legacy CFS mount point MNP packages. In case CFS

mount point MNP packages are not configured, this step ensures that there are no

dependents on the legacy CVM diskgroup MNP packages.

# cmgetconf -p <application_pkg_name> > <backedup_appl_config>

# cmdeleteconf -p <application_pkg_name>

b. Use the cfsmntadm command to delete all the legacy disk group and mount point MNP

packages managed by the Site Controller from a node in the recovery site. Use the

cfsdgadm command, if there are no CFS mounts configured.

# cfsmntadm delete <mount point>

# cfsdgadm delete <cvm_diskgroup_name>

c. Configure all the CVM diskgroups and the mount points required by an application in a

single modular SMS CFS /CVM package. Add the EMS resource, and then apply the

configuration.

# cmapplyconf -P <modular_cfs_package_file>

d. Edit the application's configuration file and change its dependency from legacy CFS

mount point or CVM disk group MNP packages to the newly created modular SMS

CFS/CVM package. Apply this package configuration

cmapplyconf -P <backedup_application_config>

e. Get the current configuration of the Site Controller. Modify the Site Controller configuration

with the new set of packages that need to be managed on the recovery site. Allow the

set of packages that are being managed on the primary site remain as is.

3. Restart the Site Controller on the primary site.

4. Halt the Site Controller package on the primary site. This will halt all the complex workload

packages that are running on the primary site.

5. Restart the Site Controller on the recovery site. The complex workload will start up on the

recovery site using the new modular SMS CFS/CVM packages.

6. Halt the Site Controller that is running on the recovery site in DETACH mode.

7. Repeat step 2 that was initially performed on the recovery site, on the primary site

8. Restart the Site Controller on the recovery site.

You can either continue the Site Controller package to run on the recovery site or move it back to

the primary site.
