Agenda
Suppose you need to replace the bge2 Ethernet with ce0 (ONLINE without restarting gab, llt and hastop -all -force)
# lltconfig -t ce0 -d /dev/ce:0
# lltconfig -u bge2
- First command will add the new Ethernet heartbeat. Second command will remove the old Ethernet heartbeat. (Dont try to remove first before adding the Ethernet).
- Run the above two commands only on the Cluster node where the Ethernet card is going to replace.
Make sure the new Heartbeat
# lltstat -nvv|more

Edit the /etc/llttab file
Replace the entry of bge2 (Old Ethernet) with ce0 (New Ethernet)

View Java Console
Under Java Console=>Cluster=>System Connectivity, you will notice a cross on the heartbeat. This cross will clear when you reboot the cluster node on which the heartbeat Ethernet is replaced.
