136 Verifying the VCS installationVerifying LLT, GAB, and cluster operationUsing lltstat -nvvWith LLT configured correctly, the output of lltstat -n shows all the nodes inthe cluster and two links for each node. If the output shows otherwise, you canuse the verbose option of lltstat.For example, type lltstat -nvv | more on a node to view additionalinformation about LLT. In the following example, lltstat -nvv | more istyped on node north in a two-node cluster:# lltstat -nvv | more

It reports on the two nodes in the cluster,north and south, plus non-existent nodes. For each correctly configured node,the information should show a state of OPEN, a status for each link of UP, and anaddress for each link. However, the output in the example shows that for thenode south the private network connection is possibly broken or theinformation in the /etc/llttab file may be incorrect.To obtain information about the ports open for LLT, type lltstat -p on anynode. In the following example, lltstat -p is typed on one node in a two-nodecluster:Node 1# lltstat -pOutput resembles:LLT port information:Port Usage Cookie0 gab 0x0opens:0 2 3 4 5 6 7 8 9 10 11 … 28 29 30 31connects: 0 1 7 gab 0x7opens:0 2 3 4 5 6 7 8 9 10 11 … 28 29 30 31connects: 0 1 31 gab 0x1Fopens:0 2 3 4 5 6 7 8 9 10 11 … 28 29 30 31connects: 0 1
