Managing HP Serviceguard A.11.20.20 for Linux, March 2014

You can also use -e in 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 -m module. 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. Persistent reservation
7.6 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. The table that follows shows the required cluster state
for many kinds of changes.
Table 13 Types of Changes to the Cluster Configuration
Required Cluster StateChange to the Cluster Configuration
All cluster nodes must be running.Add a new node
A node can be deleted even though it is unavailable or
unreachable.
Delete a node
Cluster can be running.Change Maximum Configured Packages
Cluster can be running; see“What Happens when You Change
the Quorum Configuration Online” (page 43).
Change Quorum Server Configuration
Cluster can be running. See “Updating the Cluster Lock LUN

You Change the Quorum Configuration Online” (page 43).
Change Cluster Lock Configuration (lock LUN)
Cluster can be running. See “Changing the Cluster Networking
Configuration while the Cluster Is Running” (page 230).
Add NICs and their IP addresses to the cluster
configuration
Cluster can be running. See“Changing the Cluster Networking

Delete NICs and their IP addresses, from the cluster
configuration
Cluster can be running. See “Changing the Cluster Networking
Configuration while the Cluster Is Running” (page 230).
Change the designation of an existing interface from
HEARTBEAT_IP to STATIONARY_IP, or vice versa
Cluster can be running. See “Changing the Cluster Networking
Configuration while the Cluster Is Running” (page 230)
Change an interface from IPv4 to IPv6, or vice versa
Must delete the interface from the cluster configuration,
reconfigure it, then add it back into the cluster configuration.
See “What You Must Keep in Mind” (page 230). Cluster can be
running throughout.
Reconfigure IP addresses for a NIC used by the cluster
Cluster can be running.Change NETWORK_POLLING_INTERVAL
Cluster can be running. See the entries for these parameters
under “Cluster Configuration Parameters ” (page 90)for more
information.
Change IP Monitor parameters: SUBNET,
IP_MONITOR, POLLING TARGET
Cluster can be running.Change MEMBER_TIMEOUT and
AUTO_START_TIMEOUT
Cluster and package can be running.Change Access Control Policy
Node(s) associated with the corresponding SITE or
SITE_NAME entry must be down. When the cluster is running
you cannot add SITE or SITE_NAME entries.
