Mount AIX NSF filesystem on Linux server

I'm trying to mount an AIX NFS filesystem on a Linux box and am having issues.  We are going to need the mount to be there after rebooting, so it would need to be in /etc/fstab as well.

cscx0461.mydomain.com = AIX box
uscscdve5.mydomain.com = Linux box

Here is what I'm trying to do from the uscscdve5 command line:

mount -o ro,soft cscx0416.mydomain.com:/db2ivr/wavfile/dev /home/dtuser/system/common

Here is the error I'm getting:

[root @ :/root]:> mount -o ro,soft cscx0416.core.spherion.com:/db2ivr/wavfile/dev /home/dtuser/system/common
mount: cscx0416.core.spherion.com:/db2ivr/wavfile/dev failed, reason given by server: unknown nfs status return value: -1

Here is what's in the /etc/exports on CSCX0416:

$ cat /etc/exports
/apps/psoft/eptst/tmp -access=cscx0208.mydomain.com
/db2ivr/wavfile/qa -access=cscx0108.mydomain.com:cscx1901.mydomain.com
/db2ivr/wavfile/dev -access=cscx0106.mydomain.com:cscx1801.mydomain.com:uscscdve5.mydomain

What do I need to put in my uscscdve5 /etc/fstab?

On the AIX box does an 'nslookup IP-of-Linux' return uscscdve5.mydomain.com?
please post result of:

  rpcinfo -p cscx0461.mydomain.com |grep mount

FYI - the "mydomain.com" is not the domain.  The AIX box is in the "core.spherion.com" domain and the Linux box in "spherion.com" domain.  I thought it would be better not to post the real domains initially - but am going to use them in the output below.

$ nslookup

*** uscscipa5.spherion.com can't find host/domain

^^ I guess this may be my problem.... ^^

Yep, I suspect that the lack of a PTR record in the DNS for the Linux box is the problem. You've got three options:

1) Fix the DNS so that the AIX box can resolve the hostname from the IP

2) Add a hosts file record on the AIX box for the Linux machine

3) Change the exports file to use the IP of the Linux box rather than its hostname.

Okay - the mount issue has been resolved.  The AIX admin removed the host entries in the /etc/exports:

$ cat /etc/exports
/apps/psoft/eptst/tmp -access=cscx0208.mydomain.com
/db2ivr/wavfile/qa -access=cscx0108.mydomain.com:cscx1901.mydomain.com
/db2ivr/wavfile/dev -access=cscx0106.core.spherion.com:cscx1801.core.spherion.com:uscscdve5.spherion

$ cat /etc/exports
/apps/psoft/eptst/tmp -access=cscx0208.mydomain.com
/db2ivr/wavfile/qa -access=cscx0108.mydomain.com:cscx1901.mydomain.com
