HP Serviceguard manual Reconfiguring a Cluster, Cmrunpkg -e sg/service pkg1

cmrunpkg -e sg/service pkg1

This runs all the package's modules except the services module.

You can also use -ein combination with -m. This has the effect of starting all modules up to and including the module identified by -m, except the module identified by -e. In this case the excluded (-e) module must be earlier in the execution sequence (as listed near the top of the package's configuration file) than the -mmodule. For example:

cmrunpkg -m sg/services -e sg/package_ip pkg1

NOTE: The full execution sequence for starting a package is:

1.The master control script itself

2.External pre-scripts

3.Volume groups

4.File systems

5.Package IPs

6.External scripts

7.Services

Reconfiguring a Cluster

You can reconfigure a cluster either when it is halted or while it is still running. Some operations can only be done when the cluster is halted. Table 14 shows the required cluster state for many kinds of changes.

Table 14 Types of Changes to the Cluster Configuration

Change to the Cluster Configuration	Required Cluster State
Add a new node	All systems configured as members of this cluster must be
	running.
Delete a node	A node can be deleted even though it is unavailable or
	unreachable.
Add a volume group	Cluster can be running.
Delete a volume group	Cluster can be running. Packages that use the volume group
	will not be able to start again until their configuration is
	modified.
Change Maximum Configured Packages	Cluster can be running.
Change Quorum Server Configuration	Cluster can be running; see the NOTE below this table and
	“What Happens when You Change the Quorum Configuration
	Online” (page 49).
Change Cluster Lock Configuration (LVM lock disk)	Cluster can be running; see “Updating the Cluster Lock
	Configuration” (page 295), “What Happens when You Change
	the Quorum Configuration Online” (page 49), and the NOTE
	below this table.
Change Cluster Lock Configuration (lock LUN)	Cluster can be running. See “Updating the Cluster Lock LUN
	Configuration Online” (page 295), “What Happens when You
	Change the Quorum Configuration Online” (page 49), and the
	NOTE below this table.

Add NICs and their IP addresses, if any, to the cluster configuration

Delete NICs and their IP addresses, if any, from the cluster configuration

Cluster can be running. See “Changing the Cluster Networking Configuration while the Cluster Is Running” (page 297).
