Testing the Network Manager
To test that the Network Manager is operating correctly, do the following
for each node in the cluster:
1. Identify the LAN cards on the node:
# ifconfig
and then
# cmviewcl -v
2. Detach the LAN connection from one card.
3. Use cmviewcl to verify that the network is still functioning through
the other cards:
# cmviewcl -v
4. Reconnect the LAN to the original card, and verify its status:
# cmviewcl -v
