AIX 5.3 NFS export not mounting, rpcinfo hang/timeout on server

Been trying to get a directory NFS-mounted with no success. I've tried both NFS v3 and v4, but currently trying v4. I can't figure out what's going on here.


server: sbkovwadmd01
Code:
sbkovwadmd01# chnfsdom
Current local domain: edw.dev

sbkovwadmd01# lssrc -a | grep nfs | grep active
 nfsd             nfs              335948       active
 nfsrgyd          nfs              381104       active

sbkovwadmd01# exportfs
/tmp/DOUG -vers=4,sec=sys,rw,root=sbkovwdatd01,access=sbkovwdatd01


client: sbkovwdatd01
Code:
sbkovwdatd01# chnfsdom
Current local domain: edw.dev

sbkovwdatd01# lssrc -a | grep nfs | grep active
 nfsd             nfs              283062       active
 nfsrgyd          nfs              274808       active

sbkovwdatd01# mount -o vers=4 sbkovwadmd01:/tmp/DOUG /mnt
NFS server sbkovwadmd01 not responding still trying

'rpcinfo' shows what one would expect on the client, but on the server, it just hangs and eventually times out. Whatever is causing this is most likely preventing the remote mount from happening as well, I'm guessing.

Code:
sbkovwadmd01# rpcinfo
rpcinfo: can't contact rpcbind: : RPC: 1832-008 Timed out

If I 'truss' it, below is the output after it finishes reading /etc/hosts (the leading close(3) is the /etc/hosts FD closing)

I've set up NFS services on many, many AIX servers before, but haven't run into this before. Wondering what might be getting in the way of rpcinfo/rpcbind

Code:
close(3)                                        = 0

I'm not versed with 5.3 but wasn't there an issue if multiple IP's were assigned in /etc/hosts to the same hostname?

Also, have you tried cycling all the nfs group services? I think lssrc -g nfs works? Sorry, only have 6.1 and 7.1 lpars in my environment.


I know, not much help. Sorry.

Yes, rpcbind/portmap is needed, and rpcinfo -p must show mountd and nfs and their udp/tcp ports.
Please check the following:

Thanks for the reply. Yes, there was an issue in 5.3 with duplicate /etc/hosts entries. I've already checked this is not the case here.

Thanks for the reply. Yes, I'm well aware of what should be happening. The problem is 'rpcinfo' is hanging, then eventually times out. I'm trying to figure out why that is. Whatever is causing this behavior is what's likely causing NFS mounts to also timeout/fail.
