Monitoring NFS/TCP Services with

 

 

Serviceguard NFS Toolkit

 

 

In addition to monitoring NFS/UDP services, you can monitor NFS/TCP

 

 

services with Serviceguard NFS Toolkit on HP-UX 11.x. For HP-UX 11.0,

 

 

you need at least Serviceguard NFS Toolkit A.11.00.03 to monitor

 

 

NFS/TCP services. All versions of Serviceguard NFS Toolkit for HP-UX

 

 

11i v1 and v2 can monitor NFS/TCP services.

 

 

 

IMPORTANT

 

You must enable NFS/TCP on HP-UX 11.0 for both client and server.

 

 

TCP is the default transport mode on HP-UX 11i v1 and 11i v2 and thus

 

 

does not need to be enabled on those systems.

 

 

Use the following steps to enable NFS/TCP on HP-UX 11.0:

 

 

Step

1.

Run the configuration command /usr/sbin/setoncenv NFS_TCP 1

Step

2.

Stop the NFS client with /sbin/init.d/nfs.client stop

Step

3.

Stop the NFS server with /sbin/init.d/nfs.server stop

Step

4.

Start the NFS server with /sbin/init.d/nfs.server start

Step

5.

Start the NFS client with /sbin/init.d/nfs.client start

 

 

From the NFS client, use the mount -o proto=tcp command to

 

 

establish a TCP only connection. The mount fails if TCP is not available

 

 

on the NFS server.

 

 

From the NFS client, use the mount -o proto=udp to command to

 

 

establish a UDP only connection. The mount fails if UDP is not available

 

 

on the NFS server.

 

 

To verify you are monitoring NFS/TCP services, run nfsstat -m. A

 

 

return of proto=tcp means you are monitoring NFS/TCP services. A

 

 

return of proto=udp means you are monitoring NFS/UDP services.

 

 

Use the following steps to disable NFS/TCP functionality on HP-UX 11.0:

Step

1.

Enter /usr/sbin/setoncenv NFS_TCP 0 at the command line to sets

 

 

the NFS_TCP variable in the /etc/rc.config.d/nfsconf to 0.
