Problem with network config

Note : a NODE_TIMEOUT value of 2000000 was found in line 111. For a
significant portion of installations, a higher setting is more appropriate.
Refer to the comments in the cluster configuration ascii file or ServiceGuard
manual for more information on this parameter.

Any other thought ?

Re: Problem with network config
First, it is odd (but not necessarily a problem) that the LUNs identified as the CLUSTER_LOCK_LUN is different for the two nodes. Most clusters would have those the same. Are these really the same physical LUN?
Try "cmquerycl -n node1 -C filename" on node1
then try it on node2. This helps determine the source of communication problems.

Re: Problem with network config
Yes, they are same physical EMC devices referenced by different device files on two nodes.
I did the cmcheckconf on both nodes and the error is abosolutely same.
Any other thoughts ?

This is usually an indication of a physical networking issue, not Serviceguard issues.
This could be due to any one of a number of issues.
Is there a router between the two nodes?
Is the subnet mask the same?
Is the Broadcast address the same?

Re: Problem with network config
NIC on both nodes are on the same subnet and they have same broadcast address.
I have even tried with cross over connection between these two nodes but the result is same.
NIC is Broadcom BCM5703 and the driver used is tg3.
Any other thoughts ?

Re: Problem with network config
I didn't see any specific response about my request that you run the cmquerycl on the individual nodes. Did you do that. This can be helpful in identifying whether a node has "permission" to talk to itself over the network. Don't rely on just ssh working.
