Node is refusing Serviceguard communication
I am busy with a new serviceguard 11.18 installation on HPUX 11.23 (2 node cluster).
I successfully created the cluster (cmquerycl, cmcheckconf, cmapplyconf). Did not configure the packet yet. I had to change the hostnames of both nodes and did it in the following manner:
-Cmhaltcl -v
Both nodes:
-set _parms hostname
-change hostnames and reboot
Node 1 and 2 :
-Changed the /etc/hosts, /.rhosts, /etc/cmcluster/cmclnodelist and /etc/cmcluster/cmclconf.ascii files to reflect the new node names.
-cmcheckconf тАУC cmclconf.ascii
Node olprd1 is refusing Serviceguard communication.
Please make sure that the proper security access is configured on node
olprd1 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 olprd1 resolves the IP address correctly.
cmcheckconf: Failed to gather configuration information
/etc/hosts of both nodes
127.0.0.1 localhost loopback
192.168.250.163 olprd1 #LAN1
192.168.250.164 olprd2 #LAN1
10.10.10.10 hb1 # heartbeat of olprd1 LAN0
10.10.10.11 hb2 # heartbeat of olprd2 LAN0
I тАШve gone through all the forums and checked everything but still the same error. i tried to cmcheckcl тАУC cmconf.ascii on both nodes but no luck. On both node I receive the same error and refers to the same node which is:
Node olprd1 is refusing Serviceguard communication.
I also tried cmquerycl тАУv тАУC cmclconfig.ascii -n olprd1 -n olprd2 on both nodes and recived the same error:
Node1 (olprd1)
Node olprd2 is refusing Serviceguard communication
Node2 (olprd2)
Node olprd1 is refusing Serviceguard communication.
I renamed the cmclconfig binary on both nodes as well but still the same error.
Any advice???

Re: Node is refusing Serviceguard communication
i do not have the syslog entries at the moment but will provide this as well later.
i also tried to remove both nodes from cmclnodelist and only add a +. and also tried to add the nodes and +.
first attempt/try
cat cmclnodelist

olprd2 root
second attempt/try
cat cmclnodelist
olprd1 root
olprd2 root
third attempt/try

Re: Node is refusing Serviceguard communication
The old configuration contains the old host names and may be interfering with your cmapplyconf.
You may have to run "cmdeleteconf" on all your nodes to remove all traces of the old configuration, then cmapplyconf to apply your new cluster configuration as if you were setting up a new cluster.

Re: Node is refusing Serviceguard communication
I would do the following (2 ideas)
A) stop cluster, revert back all nodes to their old name, reboot, then cmdeleteconf
change both servers to new names, reboot.
modify cluster configuration file, packages configuration files, check and apply the new conf.
B) stop cluster if running (?) (cmhaltcl) , then "/sbin/init.d/cmcluster stop"
remove on all nodes /etc/cmcluster/cmclconfig
restart "/sbin/init.d/cmcluster start"
modify cluster configuration file, packages configuration files, check and apply the new conf.
Regards
Eric

Re: Node is refusing Serviceguard communication
You may need to add -i
Then don't forget to inetd -c
Other ideas:
Have you used /var/adm/inetd.sec ?
If so, you will have to tailor it.
Have you commented out any hacl... services in /etc/services?
If you use cmclnodelist then also add 127.0.0.1 root and all the other IP addresses that you want to use (e.g. heartbeat lans etc). Do this on all nodes.
Set the permissions of cmclnodelist to 644 on all nodes.
Check the contents of /etc/rc.config.d/cmcluster
- you will have to change that eventually anyway.

Re: Node is refusing Serviceguard communication
From your HPUX box run a reverse lookup:
nslookup
nslookup
Did it resolve properly ?
If you use DNS (no matter what runs DNS) from a PC command line do the same thing and run a reverse lookup:
Did it resolve exactly the same as the one from HPUX?
Thanks,
Rita

Re: Node is refusing Serviceguard communication
So to avoid wasting time, I think the better way for you is to delete this cluster then create it again. Really.

Re: Node is refusing Serviceguard communication
Mridul
i do not have an entry in my inetd.conf file with -i.
root@olprd1:/etc/cmcluster# cat /etc/inetd.conf |grep -i hacl
hacl-probe stream tcp nowait root /opt/cmom/lbin/cmomd /opt/cmom/lbin/cmm
hacl-cfg dgram udp wait root /usr/lbin/cmclconfd cmclconfd -p
hacl-cfg stream tcp nowait root /usr/lbin/cmclconfd cmclconfd -c
Other ideas:
Have you used /var/adm/inetd.sec ?
If so, you will have to tailor it.
how should i edit this file because i am not using it:
root@olprd1:/etc/cmcluster# more /var/adm/inetd.sec
dtspc allow 127.0.0.1 loopback olprd1
root@olprd2:/etc/cmcluster# more /var/adm/inetd.sec
dtspc allow 127.0.0.1 loopback olprd2
i did reverse lookups and eveything resolved properly
i think i will just reinstall the OS and Serviceguard on both nodes becuase i would like to configure the 2x BL860c with hardware RAID and not software. its a new installation anyway.
thank you guys for your assistance and advice.
much appreciated!!
