Can you try creating an empty directory on the NFS client and manually mount the NFS filesystem to see if you get the expected behavior in the mount point when Serviceguard and AutoFS are removed from the picture?
You're attempting to list a NFS directory as root.
Most NFS servers will map the "root" user of the NFS client host as equivalent to the "nobody" user.
Usually the right way to deal with this is to make sure your username <-> UID and groupname <-> GID mappings are consistent between the client and the server, assign some meaningful group permissions & memberships, and stop trying to work on NFS filesystems as root.
(In HP-UX, if a user has rwx access to a directory, has CHOWN privilege assigned to him/her in /etc/privgrp, and there is no sticky bit on the directory, then there is not much practical difference between root and that user regarding any files in that directory.)
The lazy/special-case way would be to change the share options at the NFS server to allow root access from that particular client to that particular NFS share. See "man share_nfs" for ideas.
