control script) : legacy package
Package can be running.
See “ip_subnet” (page 176) for important information. Serviceguard will reject
the change if you are trying to add an ip_subnet that is not configured on all
the nodes on the package's node_name list.
Add or remove an ip_subnet:
modular package
Package can be running.
See “ip_subnet” (page 176) and “ip_address” (page 177) for important
information. Serviceguard will reject the change if you are trying to add an
ip_address that cannot be configured on the specified ip_subnet, or is on

configurations
Package can be running.
Serviceguard will not allow the change if the subnet being added is down, as
