Node Switch Reasons in HACMP
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 switched to the second node (standby node). I searched in the file /tmp/hacmp.out but I couldn't find why is this happend.
Is there any log file can give me the reason of this switching?
Thanks in advance

load(8) System Manager's Manual load(8)
Name
load - down-line load software to a target node
Syntax
/etc/load [ node ]
Description
The command loads software to an unattended target node. The target node is loaded by the host that executes the command.
The command requires the identification of the service circuit over which the load is performed, the Ethernet hardware address of the tar-
get node, and the service password needed to gain access to the target. This information is included in the nodes database entry for the
target node. A node entry is defined with the command. For further information, see The node is the name or address of the target node.
A node name consists of from one to six alphanumeric characters. For single networks, a node address consists of a decimal integer
(1-1023). For multiple networks, a node address consist of two decimal integers (n.n), where the first indicates the network number
(1-63), and the second indicates the node address (1-1023).
Options
-p Uses the specified service and password (next arguments) in accessing the target node. You can omit a target node's service and pass-
word from the nodes database for security reasons, but you must then specify the service and password in the command line by using the
option.
Examples
# /etc/load bangor -p 130fe
This command causes node to be loaded by the ULTRIX host node executing the command. The ULTRIX host uses the load files specified in the
nodes database entry for node to perform the load.
