Table 7-2 Types of Changes to Packages (continued)
Required Package StateChange to the Package
Package can be running.
See “ip_subnet” (page 274) and “ip_address” (page 275) 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 in
cross-subnet configurations
(page 275)): modular package
Package must not be running.Add, delete, or change
cluster_interconnect_subnet
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.
Add or remove monitoring for
a subnet: monitored_subnet for
a modular package or SUBNET
(in the package configuration
file) for a legacy package
Package can be running.
Serviceguard will not allow the change if it would cause the package
to fail.
Change
local_lan_failover_allowed
Package can be running.
Serviceguard will not allow the change if it would cause the package
to fail. In addition, Serviceguard will reject the change if the resource
is not UP within about 30 seconds. Multiple changes that take longer
than this should be done incrementally; resources that are very slow to
come up may need to be configured offline.
Serviceguard treats a change to resource_name as deleting the existing
resource and adding a new one, meaning that the existing resource is
stopped.
Add or remove a resource:
modular package
Package can be running.
Serviceguard will not allow a change to resource_up_value if it would
cause the package to fail.
Change
resource_polling_interval,
resource_start, resource_up_value:
modular package
For AUTOMATIC resources, package can be running. See the entry for
“Add or remove a resource: modular package” for more information.
For DEFERRED resources, package must not be running.
Add or remove a resource:
legacy package
