exportfs -a command fails!

[Amit Mehra_1]

Hello,
I am facing two problems on one of my HP-UX 10.20 machine. Maybe both of them are related, We are not able to find the solution for them yet. Please let us know if anybody has any suggestions for this
First:

The problem occurs when we try to export NFS on this machine.
On giving exportfs -a command it is gives the error, System call fail and causes a Core dump.

We have tried doing the following:
1.We changed the file /etc/rc.config.d/nfsconf and updated the entry NFS_SERVER=1. But no results.
2.Made the file /etc/exports. And added the necessary entry. But no results here too.
3.Started the nfs server using the command nfs.server start butit gave the error bad system calls, core dump!
4.We also checked
that /usr/lib/netsvc/fs automount - f /etc/auto_master, /usr/sbin/rpc.mountd and /usr/sbin/portmap are running but /usr/sbin/nfsd is not running.
Please let us know if anybody has idea about this problem.

Second:
utility software sam is not running properly. We are not able to update many parameters using sam. Because of this we are even not able to start the NFS or modify the kernal parameters.
It gives the error unable to read /stand/vmunix
I have attached the samlog for your reference.

Thanks you..
And Looking forward fro some quick replies..

Hi

As you seem to be getting problems with the actual vmunix I would rebuild the kernel and restart the system first off all.

cd /stand/build

mk_kernel -s system

mv /stand/system /stand/system.old
mv /stand/vmunix /stand/vmunix.old

mv /stand/build/vmunix_test /stand/vmunix

cd /
shutdown -ry now
