Verifying LLT, GAB, and cluster operation

5To view additional information about LLT, run the lltstat -nvvcommand on each node.

For example, run the following command on the node galaxy in a two-node cluster:

lltstat -nvv more

The output on galaxy resembles:

Node	State	Link	Status	Address
*0 galaxy	OPEN	eth1 UP	08:00:20:93:0E:34
		eth1 UP	08:00:20:93:0E:34
1 nebula	OPEN	eth2 UP	08:00:20:93:0E:34
1 nebula	OPEN	eth1 UP	08:00:20:8F:D1:F2
		eth1 UP	08:00:20:8F:D1:F2
		eth2 DOWN

2CONNWAIT

eth1 DOWN eth2 DOWN

3CONNWAIT

eth1 DOWN eth2 DOWN

31CONNWAIT

eth1 DOWN eth2 DOWN

Note that the output lists 32 nodes. The command reports the status on the two nodes in the cluster, galaxy and nebula, along with the details for the non-existent nodes.

For each correctly configured node, the information must show the following:

■A state of OPEN

■A status for each link of UP

■An address for each link
