ATM Configuration and Troubleshooting Guide

Configuring EMS High Availability over ATM
Migrating from HA-ATM to EMS HA-ATM
Chapter 6108
this only when you are migrating the package on the node the
package_configuration_file actually resides on (the file can be on
only one node the package runs on, within each cluster).
• package_control_script_file is the name of the
MC/ServiceGuard package control script for the package/ELAN
interface you are migrating.
This command runs the migration script. The script migrates the
package configuration and control script files, and saves the old files as
package_configuration_file .bck and
package_control_script_file .bck.
Step 3. When the package configuration file and script files have been migrated
on all nodes, run this MC/ServiceGuard command:
cmcheckconf -v -C cluster_configuration_file
-P package_configuration_file
and then run this MC/ServiceGuard command to apply the new
configuration:
cmapplyconf -v -C cluster_configuration_file
-P package_configuration_file
Step 4. Per cluster, do one of these two things:
• If you stopped the cluster in step 1 above, restart it with this
MC/ServiceGuard command:
cmruncl
Then, go to step 5 below.
• If you stopped the package in step 1 above, restart it with this
MC/ServiceGuard command:
cmrunpkg package_name
Then, go to step 5 below.
Step 5. Verify the remote recovery configuration (see “Verifying the Remote
Recovery Configuration” on page 133).
Step 6. If you want to migrate another package for remote recovery, go back to
step 1 above.
