Thanks for the update.

Your fix was to be my recommendation.

a) AIX, to boot (quickly) needs to have two IP addresses in /etc/hosts
127.0.0.1 loopback localhost
A.B.C.D hostname

b) for the AIX NFS server both server and client must agree on the name and IP address used by the client to connect (mount) on the server. There was a time that when the client used a shortname and the server a "longname" the mount would fail (I hope the shortname check is enough these days)

In short, when NFS mounts are taking a long time verify the IP address used to connect (especially from multi-homed clients). Back in telnet days I would just telnet in to the server and then use the who command to see what IP address/hostname the server reported. If it was an IP address I knew I needed to do something because the hostname - short or long - was not resolving. It might also be what I considered the alias - again, if not the name the client was announcing - the AIX server will refuse the mount.

Hope this helps your understanding!

showmount

SHOWMOUNT(8)						      System Manager's Manual						      SHOWMOUNT(8)

NAME

       showmount - show mount information for an NFS server

SYNOPSIS

       showmount [ -adehv ] [ --all ] [ --directories ] [ --exports ] [ --help ] [ --version ] [ host ]

DESCRIPTION

       showmount  queries  the	mount  daemon on a remote host for information about the state of the NFS server on that machine.  With no options
       showmount lists the set of clients who are mounting from that host.  The output from showmount is designed to appear as though it were pro-
       cessed through ``sort -u''.

OPTIONS

       -a or --all
	      List  both  the client hostname or IP address and mounted directory in host:dir format. This info should not be considered reliable.
	      See the notes on rmtab in rpc.mountd(8).

       -d or --directories
	      List only the directories mounted by some client.

       -e or --exports
	      Show the NFS server's export list.

       -h or --help
	      Provide a short help summary.

       -v or --version
	      Report the current version number of the program.

       --no-headers
	      Suppress the descriptive headings from the output.

       rpc.mountd(8), rpc.nfsd(8)

BUGS

       The completeness and accuracy of the information that showmount displays varies according to the NFS server's implementation.

       Because showmount sorts and uniqs the output, it is impossible to determine from the output whether a client is mounting the same directory
       more than once.
