Building Disaster Recovery Serviceguard Solutions Using Metrocluster with 3PAR Remote Copy

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.
Steps to restart the failed Site Controller package as follows:
1. Determine the error message logged in the package log, and then fix the problem. The error
messages, causes, and resolution are described in the chapter “Troubleshooting” (page 56).
2. Ensure that the Site Controller Package is enabled on all 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
Steps to administer Metrocluster or the packages configured under Metrocluster using Serviceguard
Manager as follows:
1. Access one of the node’s System Management Home Page available at http://
<nodename>:2301. Log in using the root user’s credentials of the node.
2. Click Tools, if Serviceguard is installed, one of the widgets will have Serviceguard as an
option. Click Serviceguard Manager link within the widget.
3. On the Cluster’s Home Page, click the Administration Tab and choose the available options
when required. Choose appropriate packages for the required option.

Rolling upgrade
Metrocluster configurations without Site Aware Disaster Tolerant Architecture (SADTA) feature
configured follow the HP Serviceguard rolling upgrade procedure. The HP Serviceguard
documentation includes rolling upgrade procedures to upgrade the Serviceguard version, the
HP-UX operating environment, and other software. This Serviceguard procedure, along with
recommendations, guidelines, and limitations, is applicable to upgrading Metrocluster versions
that do not use the SADTA feature. For more information on completing a rolling upgrade of HP
Serviceguard, see the latest edition of Managing Serviceguard, available at http://www.hp.com/
go/hpux-serviceguard-docs —> HP Serviceguard.
Figure 10 is a graphical representation of the procedures to be followed while performing a rolling
upgrade for Metrocluster configurations with or without SADTA.
