Failed to get dlm configuration.
The above mentioned commands have in common that they access the Serviceguard
configuration daemon cmclconfd to collect information for them. Basically if the Serviceguard
commands do not get a reply from the daemon they will log messages similar to those above.
There are numerous causes why a reply is not returned to the command. Ruling them out one
after another will usually resolve the problem.
If you have a problem with one of those commands you can follow the steps bellow, to
determine the reason for that.
1. Do you try to run a Serviceguard command on a node not having Servicegurad
configured and that accesses a node that is running in a cluster? E.g. you run
cmcheckconf to add a node that is not currently member of the cluster and you run the
cmcheckconf on the node that is to be added? For Serviceguard A.11.16 and later you
should run the command on the node that has Serviceguard already configured.
Otherwise you would need to change the Role Based Access Policies in the cluster.ascii
of the existing cluster to allow external nodes to modify the configuration.
2. /usr/lbin/cmclconfd exists and has appropriate execution rights. It's cksum and what
string match what is documented (e.g. in patch texts for Serviceguard).
# ls -l /usr/lbin/cmclconfd
-r-xr--r-- 1 bin bin 3725848 Mar 14 2005 /usr/lbin/cmclconfd
3. The hacl-cfg/tcp and hacl-cfg/udp ports are listed in
/etc/services. In a NIS environment the command "ypcat
services" list the ports.
# grep hacl-cfg /etc/services
hacl-cfg 5302/tcp # HA Cluster TCP configuration
hacl-cfg 5302/udp # HA Cluster UDP configuration
4. The hacl-cfg/tcp and hacl-cfg/udp ports are listed in /etc/inetd.conf on HP-UX as
hacl-cfg dgram udp wait root /usr/lbin/cmclconfd cmclconfd -p
hacl-cfg stream tcp nowait root /usr/lbin/cmclconfd cmclconfd -c
5. inetd is running and it registered the ports correctly when it was restarted last
# grep hacl-cfg /var/adm/syslog/syslog.log
