configuration file, and it will notify the other nodes in the cluster of the new MAC address. The
cluster will operate normally after this.
It is also recommended that you update the new MAC address in the cluster binary configuration
file by re-applying the cluster configuration. Use the following steps for online reconfiguration:
1. Use the cmgetconf command to obtain a fresh ASCII configuration file, as follows:
# cmgetconf config.ascii
2. Use the cmapplyconf command to apply the configuration and copy the new binary file to
all cluster nodes:
# cmapplyconf -C config.ascii
This procedure updates the binary file with the new MAC address and thus avoids data inconsistency
between the outputs of the cmviewconcl and lanscan commands.
