NFS server not responding

Chris Sparks — Mon, 12 Jun 2006 12:35:27 GMT

Just changed IP address on a 10.20 server. When trying to boot a workstation (715/80 running 11.0) that previously connected fine, it hangs at "Start NFS client subsystem" and says "NFS server not responding" and never gets past it. The workstation IP is still in the old range, but I cant get in to change it. I assume I need to get into single user mode and change the IP but not sure how.
Thanks in advance, Chris

If memory serves, SHIFT DEL, or CNTL SHFT | should get you to a prompt so you can make your changes. If not you will need to boot single user.

reboot, hit any key when prompted, boot pri
interact with IPL(Y/N) y
at ipl prompt hpux -is

That should get you into single user mode.

Reboot the workstation (you'll probably have to power cycle it), interrupt the boot process at the 10 second prompt, interact with ISL, and enter "hpux -is". This will bring you up in single user mode, already logged in as root.

A couple of additional points:

control / or is it control \
will break out of the NFS subsystem and continue the boot.

If you come up in single user mode, you might have to issue a mount -a (or just mount specific mount points) in order to have access to all the support files you need to modify the settings.

Is it posible that a router or gateway may be blocking activity to the NFS Server from the NFS Client?

Are you able to mount an exported NFS file system on the NFS Server node to check that it is created properly first before trying to mount it on the network. Then try it from a system that is in the same range (subnet) as the server. If that works then try the original client. If it doesn't work then there is probably a problem in the routing of the NFS traffic.

obviously replace all my ipl stuff above with isl.

Many thanks!!!

Control \ during the error got me to a login prompt and I was able to make the change.

Once again the forums have rescued me.
