  • El nodo puede ver los recursos del clúster con: lcmap
root@NWrhelNodeF:~# lcmap
type: NSR_CLU_TYPE;
clu_type: NSR_LC_TYPE;

type: NSR_CLU_VIRTHOST;

  • La salida de lcmap coincide con la configuración de recursos de pcs: pcs resource config

Cause

La dirección IP no se resuelve con el nombre utilizado por la configuración del clúster de NetWorker: 
root@NWrhelNodeF:~# nslookup 192.168.25.28
** server can't find 28.25.168.192.in-addr.arpa: NXDOMAIN
La IP debe resolver el valor NSR_SERVERHOST en el archivo /usr/lib/ocf/resource.d/EMC_NetWorker/Server: 
root@NWrhelNodeF:~# cat /usr/lib/ocf/resource.d/EMC_NetWorker/Server | grep SERVERHOST
                    echo "q" | nsradmin -s ${NSR_SERVERHOST} -i - > /dev/null 2>&1
                        echo "q" | nsradmin -s ${NSR_SERVERHOST} -i - > /dev/null 2>&1
NSR_SERVERHOST=NWrhelClusD.emclab.local
Este valor se establece cuando se ejecuta el script /usr/sbin/networker.cluster.

Resolution

Corrija la resolución de nombres para la VIP. El administrador de AD puede corregir esto en la configuración de DNS o mediante entradas de archivo /etc/hosts en cada nodo involucrado en el clúster. 
root@NWrhelNodeF:~# nslookup 192.168.25.28
28.25.168.192.in-addr.arpa      name = NWrhelClusD.emclab.local.

Una vez que el nombre se resuelve correctamente, se pueden iniciar los servicios de NetWorker:

root@NWrhelNodeF:~# pcs resource cleanup nws
Cleaned up fs on NWrhelNodeF.emclab.local
Cleaned up fs on NWrhelNodeE.emclab.local
Cleaned up ip on NWrhelNodeF.emclab.local
Cleaned up ip on NWrhelNodeE.emclab.local
Cleaned up nws on NWrhelNodeF.emclab.local
Cleaned up nws on NWrhelNodeE.emclab.local

root@NWrhelNodeF:~# pcs resource
  * Resource Group: NW_group:
    * fs        (ocf::heartbeat:Filesystem):     Started NWrhelNodeF.emclab.local
    * ip        (ocf::heartbeat:IPaddr):         Started NWrhelNodeF.emclab.local
    * nws       (ocf::EMC_NetWorker:Server):     Started NWrhelNodeF.emclab.local
