Asegúrate de que el paquete rpcbind o portmapper esté instalado en el host Linux. Ejecuta:
# rpm -qa | grep rpcbind
Debería devolver algo parecido a esto: rpcbind-0.1.6+git20080930-6.15
Si no ves nada, debes instalar los paquetes con YaST o zypper:
Con YaST: # yast2 --install rpcbind
Usar Zypper: # zypper install rpcbind
Consultar información del cliente NFS desde el host Linux
En el host debe instalarse un paquete y una versión del cliente NFS aprobados por Backup and DR.
Comprueba si el servicio portmapper o rpcbind se está ejecutando. Ejecutar:
# sudo service rpcbind status
Un host Red Hat RHEL 6 o CentOS Linux debería devolver algo parecido a lo siguiente:
rpcbind (pid 1591) is running...
Un host Linux SLES debería devolver algo parecido a lo siguiente:
Checking for service rpcbind running
Si el servicio rpcbind no se está ejecutando en el host de Linux, inícialo con el siguiente comando:
# sudo service rpcbind start
Usa rpcinfo para enumerar los programas o servicios RPC registrados. Portmapper
debe estar registrado y en ejecución.
# sudo rpcinfo -p
program vers proto port service
100000 4 tcp 111 portmapper
100000 3 tcp 111 portmapper
100000 2 tcp 111 portmapper
100000 4 udp 111 portmapper
100000 3 udp 111 portmapper
100000 2 udp 111 portmapper
Comprueba si el host Linux puede hacer una llamada a procedimiento remoto a los programas rpcbind y NFS en el dispositivo de copia de seguridad o recuperación mediante lo siguiente.
# sudo rpcinfo -T tcp <#vm internal IP> rpcbind
program 100000 version 2 ready and waiting
program 100000 version 3 ready and waiting
program 100000 version 4 ready and waiting
# sudo rpcinfo -T tcp <#vm internal IP> nfs
program 100003 version 2 ready and waiting
program 100003 version 3 ready and waiting
Si los comandos anteriores devuelven el resultado que se muestra, significa que la conectividad NFS del host Linux al dispositivo de copia de seguridad o recuperación es correcta.
