Building Disaster Recovery Serviceguard Solutions Using Metrocluster with EMC SRDF

To move a complex workload to a remote site:

1. Halt the Site Controller Package of the complex workload.

# cmhaltpkg <site_controller_package_name>

2. Ensure the complex-workload packages are halted successfully.

# cmviewcl -l package

3. Start the Site Controller Package on a node in the remote site.

# cmrunpkg <site_controller_package_name>

The Site Controller package starts up on a node in the remote site and starts the complex-workload

packages that are configured.

Restarting a failed Site Controller package

If the running Site Controller package fails because of transient error conditions, restart the Site

Controller package on a node in the site where it was previously running.

To restart the failed Site Controller package:

1. Determine the error message logged in the package log, and fix the problem. The error

messages, causes and resolution are described in “Troubleshooting” (page 71).

2. Ensure that the Site Controller Package is enabled on all the nodes in the site where it was

failed.

# cmmodpkg –e –n <siteA node 1> —n <siteB node 2>\

<site_controller_package_name>

3. Start the Site Controller Package on a node in the same site where it was previously running.

# cmrunpkg <site_controller_package_name>

Administering Metrocluster with Serviceguard Manager

Follow the steps described here to administer Metrocluster or the packages configured under

Metrocluster using Serviceguard Manager.

1. Access one of the node’s System Management Home Page at http://<nodename>:2301.

2. Click Tools, if Serviceguard is installed, one of the widgets will have Serviceguard as an

option. Click the Serviceguard Manager link within the widget.

3. On the Cluster’s Home Page, click the Administration tab and select the required options.

Select the appropriate packages for the required option.
