Table 10 Types of Changes to Packages (continued)
Required Package StateChange to the 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.Add or delete nodes from
package’s
Serviceguard will reject the change if you are trying to add a node on which
the specified ip_subnet is not configured.
ip_subnet_node
list(page 215) in cross-subnet
configurations
Package can be running.Add or remove monitoring
for a subnet:
Serviceguard will not allow the change if the subnet being added is down,
as that would cause the running package to fail.

a modular package or
SUBNET (in the package
configuration file) for a
legacy package
Package must not be running.Add, change, or delete a
pv: modular package
NOTE: pv (page 222) is for use by HP partners only.
Package can be running.Add a volume group:
modular package
Package must not be running.Add a volume group:
legacy package
Package should not be running.Remove a volume group:
modular package
CAUTION: Removing a volume group may cause problems if file systems,
applications or other resources are using it. In addition the CAUTION under
“Remove a file system: modular package” applies to any file systems using
the volume group.
Package must not be running.Remove a volume group:
legacy package
Package should not be running (unless you are only changing
fs_umount_opt).
Change a file system:
modular package
Changing file-system options other than fs_umount_opt may cause problems
because the file system must be unmounted (using the existing
fs_umount_opt) and remounted with the new options; the CAUTION under
“Remove a file system: modular package” applies in this case as well.
If only fs_umount_opt is being changed, the file system will not be
unmounted; the new option will take effect when the package is halted or the
file system is unmounted for some other reason.
