booting gets hang at nfs client subsystem

[Eugene_15]

when i boot my hp-ux 10.20 ace, it gets hanged at nfs client subsystem.

any ideas why?

[Steven E. Protter]

Are you saying that prior to installation of the ace, this didn't happen?

Here are some general ideas though some error messages from the console or /var/adm/syslog/syslog.log would be very helpful.

Check networking.

Look for obvioius typos in the file:

/etc/rc.config.d/netconf

A little syntax problem there will produce this your error, take it from someone who has done this to himself.

Check for valid and consistent entries and the presence of the following files:

/etc/nsswitch.conf
/etc/hosts

This is a start. Post some data while I'm still awake and I'll help you finish.

Hi,

Other than the below information, have you got the latest patch bundle for 10.20 loaded?(December 2001)
Here is some general information from the Technical Knowledge Base.

This is a new installation. The system hangs when the NFS CLIENT
or NFS SERVER is started in the startup scripts.

How can this problem be resolved?

CONFIGURATION
New Installation

RESOLUTION
To resolve the problem:

1. Interrupt the boot sequence with CTRL SHIFT | (pipe),
or reboot into single-user mode.

2. Modify the /etc/rc.config.d/nfsconf file:

A. Change NFS_CLIENT=0 from NFS_CLIENT=1.

B. Chnage NFS_SERVER=1 to NFS_SERVER=0.

3. Continue the reboot, or reboot the system.

It is often the case, that the system either is not using NFS at all,
or the NFS Servers listed in /etc/fstab are down, or not responding.
If the system is not intended to use NFS, then these steps should
resolve the issue.

However, if the system is intended to use NFS, then examine the NFS
servers listed in /etc/fstab to determine if they are indeed up and
serving NFS. To prevent down NFS servers from hanging the boot
sequence, the bg mount option should be specified in /etc/fstab.

For example, the following /etc/fstab entry...

test.atl.hp.com:/ /nfs/test nfs rw,suid 0 0

...should be changed to:

test.atl.hp.com:/ /nfs/test nfs bg,rw,suid 0 0

After modifying /etc/fstab, edit NFS_CLIENT=1 in
/etc/rc.config.d/nfsconf so that the NFS client will function at the
next reboot. Afterwards, run the /sbin/init.d/nfs.client start script
to start NFS client, or reboot the system.

Hi,

It usually happens in 11.0

Get in to single user mode.
set the flags of NFS_SERVER/NFS_CLIENT in /etc/rc.config.d/nfsconf to 0
#init 3

after the machine boots, set the flags of the said variables to 1
#/sbin/init.d/nfs.server start
#/sbin/init.d/nfs.client start

will start nfs daemons
