You lost all heartbeats from node 1 to node 2 - thats the reason for the crash. This might happen when your system is simply too busy - but since you should have both heartbeat on disk and heartbeat via network, you should think that there is time enough to send at least one every couple of seconds, Your cluster heartbeat settings might be too tight - giving it more time for the heartbeat might help preventing this issue in the future.
Just out of curiosity - using GPFS and HACMP and RAC on the same systems appears to me to be a completely unnecessary setup, as you are running essentially 3 different cluster products on a system when RAC alone would suffice. Why ?

Hi Guys,
I have two nodes clustered. Each node is AIX 5.2 & they are clustered with HACMP 5.2. The mode of the cluster is Active/Passive which mean one node is the Active node & have all resource groups on it & the 2nd node is standby.
Last Monday I noted that all resource groupes have been... (2 Replies)

o2cb_ctl
o2cb_ctl(8) OCFS2 Manual Pages o2cb_ctl(8)
NAME
o2cb_ctl - Control program for the O2CB cluster service.
SYNOPSIS
o2cb_ctl -C -n object -t type [-i] [-a attribute ]
o2cb_ctl -D -n object [-u]
o2cb_ctl -I [-o-z] -l manager> [-n object>] [-t type] [-a attribute]
o2cb_ctl -H [-n object] [-t type>] [-a attribute>]
o2cb_ctl -h
o2cb_ctl -V
DESCRIPTION
o2cb_ctl is the control program for the O2CB cluster service. Users are not advised to use this program directly but instead use the O2CB
init service and/or ocfs2console.
OPTIONS
-C Create an object in the OCFS2 Cluster Configuration.
-D Delete an object from the existing OCFS2 Cluster Configuration.
-I Print information about the OCFS2 Cluster Configuration.
-H Change an object or objects in the existing OCFS2 Cluster Configuration.
-h Displays help and exit.
-V Print version and exit.
OTHER OPTIONS
-a <attribute>
With -C, <attribute> is in format "parameter=value", where the parameter is a valid parameter that can be set in the file
/etc/ocfs2/cluster.conf. With -I, <attribute> may be "parameter", indicating an attribute to be listed in the output, or it may be
"parameter==value", indicating that only objects matching "parameter=value" are to be displayed.
-i Valid only with -C. When creating something (node or cluster), it will also install it in the live cluster. If the parameter is not
specified, then only update the /etc/ocfs2/cluster.conf.
-n object
object is usually the node name or cluster name. In the /etc/ocfs2/cluster.conf file, it would be the value of the name parameter
for any of the sections (cluster or node).
-o Valid only with -I. Using this parameter, if one asks o2cb_ctl to list all nodes, it will output it in a format suitable for shell
parsing.
-t type
type can be cluster, node or heartbeat.
-u Valid only with -D. When deleting something (node or cluster), it will also remove it from the live cluster. If the parameter is not
specified, then only update the /etc/ocfs2/cluster.conf.
-z Valid only with -I. This is the default. If one asks o2cb_ctl to list all nodes, it will give a verbose listing.
EXAMPLES
Add node5 to an offline cluster:
$ o2cb_ctl -C -n node5 -t node -a number=5
-a ip_address=192.168.0.5 -a ip_port=7777
-a cluster=mycluster
Add node10 to an online cluster:
$ o2cb_ctl -C -i -n node10 -t node -a number=10
-a ip_address=192.168.1.10 -a ip_port=7777
-a cluster=mycluster
Note the -i argument.
Query the IP address of node5:
$ o2cb_ctl -I -n node5 -a ip_address
Change the IP address of node5:
$ o2cb_ctl -H -n node5 -a ip_address=192.168.1.5
