Managing Serviceguard Eighteenth Edition, September 2010

4. Verify the new configuration:
cmcheckconf -C clconfig.ascii
5. Apply the changes to the configuration and distribute the new binary configuration
file to all cluster nodes:
cmapplyconf -C clconfig.ascii
Removing a LAN or VLAN Interface from a Node
You must remove a LAN or VLAN interface from the cluster configuration before
removing the interface from the system.
On an HP-UX 11i v3 system, you can then remove the interface without shutting down
the node. Follow these steps on the affected node:
NOTE: This can be done on a running system only on HP-UX 11i v3. You must shut
down an HP-UX 11i v2 system before removing the interface.
1. If you are not sure whether or not a physical interface (NIC) is part of the cluster
configuration, run olrad -C with the affected I/O slot ID as argument. If the NIC
is part of the cluster configuration, you’ll see a warning message telling you to
remove it from the configuration before you proceed. See the olrad(1M) manpage
for more information about olrad.
2. Use the cmgetconf command to store a copy of the cluster’s existing cluster
configuration in a temporary file. For example:
cmgetconf clconfig.ascii
3. Edit clconfig.ascii and delete the line(s) specifying the NIC name and its IP
address(es) (if any) from the configuration.
4. Run cmcheckconf to verify the new configuration.
5. Run cmapplyconf to apply the changes to the configuration and distribute the
new configuration file to all the cluster nodes.
6. Runolrad -d to remove the NIC.
See also “Replacing LAN or Fibre Channel Cards” (page 407).
Changing the LVM Configuration while the Cluster is Running
You can do this in Serviceguard Manager, or use HP-UX commands as in the example
that follows.
