Testing the Cluster Manager
To test that the cluster manager is operating correctly, perform the following steps for
each node on the cluster:
1. Turn off the power to the node SPU.
2. To observe the cluster reforming, enter the following command on some other
configured node:
cmviewcl -v
You should be able to observe that the powered down node is halted, and that its
packages have been correctly switched to other nodes.
3. Turn on the power to the node SPU.
4. To verify that the node is rejoining the cluster, enter the following command on
any configured node:
cmviewcl -v
The node should be recognized by the cluster, but its packages should not be
running.
5. Move the packages back to original node (see “Moving a Failover Package ”
(page 352)).
6. Repeat this procedure for all nodes in the cluster one at a time.
Testing the Network Manager
To test that the network manager is operating correctly, for each node on the cluster
do the following:

and then
cmviewcl -v
2. Disconnect the LAN connection from the Primary card.
