NFS server unable to open connection to tcp6/udp6 networks

This document (7011354) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11 Service Pack 2

Situation

When starting the nfs server daemon, the following output is received:
sles11sp2:~ # /etc/init.d/nfsserver start
Starting kernel based NFS server: idmapd mountdrpc.mountd: svc_tli_create:
could not open connection for udp6
rpc.mountd: svc_tli_create: could not open connection for tcp6
rpc.mountd: svc_tli_create: could not open connection for udp6
rpc.mountd: svc_tli_create: could not open connection for tcp6
rpc.mountd: svc_tli_create: could not open connection for udp6
rpc.mountd: svc_tli_create: could not open connection for tcp6
statd nfsdrpc.nfsd: address family inet6 not supported by protocol TCP
sm-notify
done
sles11sp2:~ #

Resolution

To prevent this message, edit /etc/netconfig and disable the lines that configure udp and tcp settings for IPv6:
udp        tpi_clts      v     inet     udp     -       -
tcp        tpi_cots_ord  v     inet     tcp     -       -
#udp6       tpi_clts      v     inet6    udp     -       -
#tcp6       tpi_cots_ord  v     inet6    tcp     -       -
rawip      tpi_raw       -     inet      -      -       -
local      tpi_cots_ord  -     loopback  -      -       -
unix       tpi_cots_ord  -     loopback  -      -       -

Cause

IPv6 was disabled globally in YaST2 but RPC calls still try to establish connections to tcp6 or udp6 networks as configured in /etc/netconfig.
