client is able to use by issuing the snapadmin add_backup command.

Refer to the HP-UX SNAplus2 Administration Command Reference for

more information about this command.

No Active Nodes Displayed

If the snapadmin query_node_all does not report any nodes, check the

following:

Step 1. Check that the domain name and the name of the server were both

speciﬁed correctly when the client was installed by doing the following:

• Issue the snapadmin query_sna_net command on the server

• Check the sna_clnt.net ﬁle on the client

If the names do not match in both locations then modify the names in the

sna_clnt.net ﬁle on the client so that they do.

Step 2. Check whether the client has been conﬁgured to locate its server using

broadcasts on a TCP/IP network that is not set up to route broadcast

messages from the client to the server. If this is the case then specify the

server name explicitly in the sna_clnt.net ﬁle.

Step 3. Check whether there are any active servers by issuing snap start,

followed by snapadmin status_node on the server.

If you have carried out all of these checks and ﬁxed any problems, and

the snapadmin query_node_all still does not report any nodes then

there may be a problem with the underlying TCP/IP network that

SNAplus2 uses for its client/server communication. In this case you

should consult your System Administrator.

Check that a Windows Client Can See its Server

A Windows client requires the services of a server before it can operate.

Check that the Windows client is started. Refer to the HP-UX SNAplus2

Installation Guide for information about how to check this and how to

start the Windows client.

If the Windows client is started but is still not working, check the

following:

Step 1. Ensure that you have installed and conﬁgured client support on the

server by issuing snapadmin query_sna_net.
