Service Guard Problem
I have a problem when I'm tring to run cmquerycl on a to new nodes runnig Red Hat ES 4 on VMWare server.
The messeage I get is:
Looking for other clusters ... Done
Node lnx3 is refusing Serviceguard communication.
Please make sure that the proper security access is configured on node
lnx3 through either file-based access (pre-A.11.16 version) or role-based
access (version A.11.16 or higher) and/or that the host name lookup
on node lnx3 resolves the IP address correctly.
Failed to gather configuration information.
Nslookup look fine, and ping is flowing well.
I'm attaching my host file:
# Do not remove the following line, or various programs
# that require network functionality will fail.
#### LoopBack Adresses
# IPv4 Lo
127.0.0.1 localhost.localdomain localhost
#### Cluster Member Nodes
# First Cluster Member Node (This Node)
14.0.0.1 rhlnx3.test rhlnx3
# Second Cluster Member Node
14.0.0.2 rhlnx4.test rhlnx4
#### Heartbeat Connections
# First Heartbeat Connection (This node)
13.0.0.1 lnx3
# Second Heartbeat Connection
13.0.0.2 lnx4
#### Packeges IP's
My cmclnodelist looks like that:
############################################################
# Do Not Edit This File
# This is only a temporary file to bootstrap an unconfigured
# node with Serviceguard version A.11.16
# Once a cluster is created, Serviceguard will not consult
# this file, and it's to be removed then.
############################################################
lnx3 root # Cluster1, Node 1
lnx4 root # Cluster1, Node 2
Also the messages log show nothing.
Pleas help me cause I don't have any idea.
Thanks

Re: Service Guard Problem
Please make sure about below things.
1.nslookup, linkloop all should be happned between all NIC Cards.
2.login to other node with out passwd like remsh hostname.
3.service guard should be installed into both the noeds with licence.
then try with
clquerycl -C clustername -n node1 -n node2

Re: Service Guard Problem
check it out in /etc/inetd.conf
auth stream tcp6 wait bin /usr/lbin/identd identd
and also:
hacl-cfg dgram udp wait root /usr/lbin/cmclconfd cmclconfd -p
hacl-cfg stream tcp nowait root /usr/lbin/cmclconfd cmclconfd -c
if you change the file, then reload the info
inetd -c

#### Heartbeat Connections
# First Heartbeat Connection (This node)
13.0.0.1 lnx3

This assumes that the hostnames of the two systems are lnx3 and lnx4.

Some of my "standard response" is here:

This should be a good start.

Re: Service Guard Problem
First of all, thanks for trying helping me.
secomd I will reply each of you.
Suraj: service guard is install on both nodes and i had a problem to rlogin, but i fixed it.
I don't sure I understood your first remark about the nslookup.
can you give an exsample?
Orange_adm: the files you mentioned looks like they should.
John Bigg: I change /etc/hosts like you said and the only change is that i get "Permission denied to 13.0.0.2
Warning: Unable to determine local domain name for rhlnx3" before the message i got before.
Serviceguard for Linux: I made sure that identd works fine and I even tried to disable identd before I possed this thread.
If all of you guy have more idea I will like to hear them
Thanks
