After Replacing the Card
After the on-line or off-line replacement of LAN cards has been done,
Serviceguard will detect that the MAC address (LLA) of the card has
changed from the value stored in the cluster binary 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 on-line 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.
