Can not get cluster information.
Check if clinfo is running.
I have stopped and started everything and cldump works fine after clstrmgrES was restarted. The clstart and clstop have been run numerous times but clinfo will not run correctly. It runs correctly on the active node!

The problem is with the communication between the cluster nodes. You did not say which HACMP release you use. Depending on it check SNMP and/or clcomd.

cluster
CLUSTER(1) General Commands Manual CLUSTER(1)
NAME
cluster - find clusters in a graph and augment the graph with this information.
SYNOPSIS
cluster [-v?] [ -Ck ] [ -ck ] [ -o outfile ] [ files ]
DESCRIPTION
cluster takes as input a graph in DOT format, finds node clusters and augments the graph with this information. The clusters are specified
by the "cluster" attribute attached to nodes; cluster values are non-negative integers. cluster attempts to maximize the modularity of the
clustering. If the edge attribute "weight" is defined, this will be used in computing the clustering.
OPTIONS
The following options are supported:
-Ck specifies a targeted number of clusters that should be generated. The specified number k is only a suggestion and may not be real-
isable. If k == 0, the default, the number of clusters that approximately optimizes the modularity is returned.
-ck specifies clustering method. If k == 0, the default, the modularity will be used. If k == 1 modularity quality will be used.
-ooutfile
Specifies that output should go into the file outfile. By default, stdout is used.
-v Verbose mode.
EXAMPLES
Applying cluster to the following graph,
graph {
1--2 [weight=10.]
2--3 [weight=1]
3--4 [weight=10.]
4--5 [weight=10]
5--6 [weight=10]
3--6 [weight=0.1]
4--6 [weight=10.]
}
gives
graph {
node [cluster="-1"];
1 [cluster=1];
2 [cluster=1];
3 [cluster=2];
4 [cluster=2];
5 [cluster=2];
6 [cluster=2];
1 -- 2 [weight="10."];
2 -- 3 [weight=1];
3 -- 4 [weight="10."];
4 -- 5 [weight=10];
5 -- 6 [weight=10];
3 -- 6 [weight="0.1"];
4 -- 6 [weight="10."];
}
