Most of the above information can be collected using an internal HP support tool, nfsinfo. This
tool is HP’s intellectual property and is proprietary. It should be used outside of HP only in the
context of a support case. This tool does not perform a nettl trace which needs to be run while
recreating the problem. The basic techniques involved in nettl tracing are covered in the
previous chapter of this handbook.
nfsinfo can be found at the following link:

Common errors include:
nfs server … not responding - The answer from the server does not reach the client in
time. It has to be checked, whether the request reaches the server, or the server is unable to
handle the request, to organize the data and to send an answer back to the client, or the answer
reaches the client and the client is unable to handle it.
… access denied- rpc.mountd does not allow the request from the specific client. On the
client use “showmount -e <server name>” to check which file systems are exported by the
server. Login to server from this client to check how the server recognizes the client with “who -
R am I”
AutoFS
The automountd daemon implements AutoFS and replaces the legacy automount daemon. The
automount program is used to install automatic mount points. The intent of AutoFS is to make
mounting of NFS file systems more flexible. Configuration file /etc/rc.config.d/nfsconf:
AUTOFS=1
The central configuration file for the daemon is:
/etc/auto_master
This file contains the information or directs to other alternative files – maps – with the
information regarding the file systems to be mounted.
