Impact

New online capabilities improve cluster uptime

Compatibility

Some restrictions on Serviceguard rolling upgrade when Storage Management Suite upgrades are involved
Changes to naming restrictions for a small number of package-configuration parameters may require changes to these names if existing packages are reconfigured
Note that Serviceguard uses ports and services which may be disabled or blocked in certain Bastille configurations, security levels, or firewall configurations. Thus Serviceguard is incompatible with those specific configurations.
