Problem with MC /Service Guard still not resolve!!!

parametrs: HP9000/L2000
OS: HP-UX11.00
MC/ServiceGuard:A.11.09

Host name in files /etc/rc.config.d/netconf and /etc/hosts ->look as "host_name.full_domain_name".
The command "cmquerycl -v -C conf.ascii -n host_name.full_domain_name" creates conf.ascii whith node_name short name /without "full_domain_name"/.
"cmcheckconf" and "cmapplyconf" finished without errors, but "cmruncl":
cmruncl : Unable to determine the nodes on the current cluster
cmruncl : Either no cluster configuration file exists, or the file is corrupted
, or /usr/lbin/cmclconfd is unable to run
...
If I complete in conf.ascii node_name with full_domain_name then "cmcheckconf":
Error: Unable to establish communication to node host_name.full_domain_name
cmcheckconf : Unable to reconcile configuration file conf.ascii
with discovered configuration information.

Where is the problem?
files:/etc/hosts;/etc/resolv.conf;/etc/nsswitch.conf and DNS is correct!!!

Are you running multiple network cards ? (You should be - how many, which ones are for primary lan/heartbeat etc.)

How many, which IP's/subnet/gw on them ?

Are you trying to run multiple IP's on a single network interface ?

I believe that your problem is that you are trying to use a fully qualified name. I personally have never used hostname.full_domain_name in a serviceguard conf file or in the /etc/rc.config.d/netconf file.
The way I setup machines is to use the hostname in /etc/rc.config.d/netconf. Create a /etc/resolv.conf with an entry:
domain full_domain_name
nameserver .
For /etc/hosts
hostname.full_domain_name hostname

note hostname without the domain at the end of the line.

Then in all serviceguard file just use hostname

I sometime add the extra hosts within the serviceguard cluster in /etc/hosts incase the DNS is not available using the same format as above.

Dora,
Have you tried the "Microsoft method"? Reboot each node in the cluster. Sometimes the cmcld daemons get confused.
If you can focus your eyes far and straight enough ahead of yourself, you can see the back of your head.

Stephen Doud and John Waller (see above) gave the answer. follow them and you should be out of this problem. Please remember this will require a reboot too. If you still have problem than post the contents of /etc/hosts, /etc/rc.config.d/netconf, /etc/nsswitch.conf, /etc/resolv.conf.

let me say this again, don't use fully qualified hostname (hostname.domainname) in netconf and conf.ascii!!
Good luck
