For each package you want to migrate for remote recovery, follow these
steps (note that you must do this on each node the package runs on,
within each cluster):
Step 1. Per cluster, do one of these two things:
• If the cluster configuration has no packages that use the ELAN
interface resource, ensure that the cluster is not running. This is
because the ELAN interface will be a new resource for the cluster,
and so the cluster will not recognize it. If you need to stop the cluster,
use this MC/ServiceGuard command:
cmhaltcl -f
Then, go to step 2 below.
or
• If the cluster configuration has a package that uses the ELAN
interface resource (so that the cluster recognizes the ELAN
interface), you need to ensure that only the package is not running
(the cluster can still be running). If you need to stop the package, use
this MC/ServiceGuard command:
cmhaltpkg package_name
Then, go to step 2 below.
Step 2. On each node the package runs on, run this command (type it all on one
line):
/opt/hatmmon/sbin/hatmmigrate -n service_name
-e ELAN_interface_name [-p package_configuration_file]
-s package_control_script_file
where
• service_name is the service name for the ELAN interface that is
specified in the MC/ServiceGuard package configuration file.
• ELAN_interface_name is the name of the ELAN interface you are
migrating remote recovery for.
• package_configuration_file is the name of the MC/ServiceGuard
package configuration file for the package/ELAN interface you are
migrating. Note that this parameter is optional: You need to specify
