See “ip_subnet” (page 205) and “ip_address” (page 206) 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 a
subnet that is not configured on all the nodes on the package's node_name
list.
Add or remove an
ip_address: modular package
Package must not be running. (Also applies to cross-subnet configurations.)Add or remove an IP (in
control script): legacy
package
Package can be running.
Serviceguard will reject the change if you are trying to add a node on which
the specified ip_subnet is not configured.
Add or delete nodes from
package’s ip_subnet_node
list(page 206) in
cross-subnet configurations
Package can be running.
Serviceguard will not allow the change if the subnet being added is down,
as that would cause the running package to fail.

CAUTION: Removing a volume group may cause problems if file systems,
applications or other resources are using it. In particular, if the volume group
cannot be deactivated and kill_processes_accessing_raw_devices is set to yes,
processes accessing the volume group as a raw device will be killed; in
addition the CAUTION under “Remove a file system: modular package”
applies to any file systems using the volume group.
