Verifying Network Connections and Services
Verifying Network Connections and
Services
Several line verification tests are available to help you verify the
operation of NS 3000/iX services and link products.
NSLOGON establishes temporary connections to other nodes to verify
that the network transport is operating correctly between the two
nodes using the connection.
XPVAL is an interactive test that uses the NetIPC intrinsics to make
sure that the network transport is working correctly.
QVALNS and NSTEST both perform a quick validation of the Network
Services. QVALNS runs through a job while NSTEST runs interactively.
You can run all of these tests either standalone or through the NETTOOL
utility. Hewlett-Packard suggests that you run them through the
NETTOOL utility to take advantage of its facilities, including online help.
To Check the Network Transport
Perform the following steps to use XPVAL to check the network
transport. (Note that you may also use NSLOGON to establish a
temporary connection between nodes to check the network services. See
Chapter 6, “Using NETTOOL,” for more information.)
1. Make sure the network transport is active on this node and on any
other node that will be a part of this test.
2. Run the NETTOOL utility by entering the program name:
NETTOOL.NET.SYS
The root menu will appear.
3. Enter XPVAL to run the transport validation.
4. XPVAL will run a local program (XPVALLOC) and will prompt you for
the information it needs to perform the validation. To check the local
transport, enter information about the local loopback NI.
5. To check the transport between the local node and a remote node,
make sure XPVAL is running on the remote node as well and enter
information about the remote node.
6. XPVAL will run a one minute connection test to verify the operation
of the transport and report any errors it encounters. See information
on the error messages.
