Command Errors 

If you are using the interactive capabilities of NS3000/iX and associated
links and receive an error, refer to "NS3000/iX Network Services Error
Messages" in the NS3000/iX Error Messages Reference Manual.

The command errors fit into four categories:

   *   Syntax errors or invalid options.  These errors result from user
       errors when issuing the command.  They are readily corrected by
       checking for the correct syntax and reissuing the command.

   *   Warnings.  If a command is executable but may give unexpected
       results, a warning is issued.  This would occur in a situation
       where conflicting options were specified.  The warning informs you
       which option was actually used (or not used).

   *   Resource Errors.  These errors occur when a system resource needed
       for the execution of the command is not available.  If they occur,
       you can wait and reissue the command later, when the resource may
       be available.  If resource errors happen frequently the
       configuration or resource allocation of the system may be
       inadequate.  The network manager may need to investigate further.

   *   Internal Errors.  These errors indicate that the software
       is malfunctioning.  If they ever occur, notify your HP
       representative.  The network manager should follow the steps
       outlined in appendix B, "Submitting an SR."

For syntax errors and warnings, consult the reference pages in this
manual for that command's correct syntax and options, or refer to Using
NS3000/iX Network Services. 

Line Opening Errors 

There are several reasons why a DSLINE command for opening a
communications line might be rejected.  Some line opening errors actually
occur when a REMOTE HELLO (or DSCOPY, or programmatic RPMCREATE or FOPEN)
is executed, not when the DSLINE is done.  The following list summarizes
the likely causes of line opening failures:

   *   The user made a syntax error in the DSLINE command.

   *   The user specified an erroneous nodename or envid in the DSLINE
       command.  The node name must match the one configured for the
       system the user is trying to reach.  Make sure that all users know
       the correct node names.  You may want to post a map with the
       configured node names for all the nodes on the network.  The
       correct node names can be checked in the network directory (if one
       is being used).

   *   A network was not started by the local console operator, the
       remote console operator, or any intermediate nodes.  Check that
       all required commands have been issued on the local, remote, and
       intermediate nodes.  The network interfaces, the LAN NI, the
       loopback NI, point-to-point NI, X.25 NI, token ring NI, and
       gateway half NI, must be initialized with NETCONTROL START
       commands.  The DTC/X.25 Network Access card in the DTC must be
       started; refer to Using the OpenView DTC Manager or Configuring 
       and Managing Host-Based X.25 Links.  The Network Services must be
       initialized with the NSCONTROL START command.  Some links may also
       need to be started by NETCONTROL ADDLINK commands.  Links can be
       configured not to be started when a NETCONTROL START command is
       executed and be started via NETCONTROL ADDLINK. Links may have
       been closed by NETCONTROL DELLINK or may have been closed because
       an irrecoverable error was detected on the line.

   *   The remote node may not be operational.

   *   The remote operator may have lowered the session limit.  This
       would cause a failure in a REMOTE HELLO or a DSCOPY or RPMCREATE
       that tried to automatically log on to a session.

   *   The local console operator may have used the service list of the
       NSCONTROL command to limit the Network Services to incoming users
       only.  On the remote node, the operator may have limited the
       Network Services to outgoing only.  This would cause a REMOTE
       HELLO, DSCOPY, remote FOPEN, or RPMCREATE to fail, depending on
       which services were not started.

   *   If the line is a dial up line, a failure in a REMOTE HELLO, DSCOPY
       or RPMCREATE can be caused by the following:

          *   If auto dial, the number was busy, wrong, or was never
              answered at the remote computer.

          *   The security strings did not match at either the local or
              remote node (if security was enabled).

          *   The IP address of the remote node was not configured as a
              candidate for use of this link.

          *   If the link is a shared dialup link, a failure will occur
              if the link is connected to a node different than the one
              issued in the DSLINE command.

          *   When a REMOTE HELLO is issued which causes the phone to be
              dialed, there is a window in which subsequent REMOTE HELLOs
              from other users will be rejected.  The window is from the
              time the auto dial starts (or dial request) to when the
              connection is established.

   *   A REMOTE HELLO, DSCOPY or RPMCREATE will fail if the IP address of
       the remote node configured in the network directory does not match
       the IP address of the remote node configured in the NS
       Configuration file.

   *   All virtual terminals on the remote node are already in use, which
       means there are no remote resources available to establish a
       remote session.  This would cause a failure in a REMOTE HELLO or a
       DSCOPY or RPMCREATE that tried to automatically log on to a
       session.

   *   Someone has exclusive access to the specified line or the user
       requested exclusive access to a line that is already in use.

   *   Someone is exclusively accessing a server program.  For example,
       someone is executing the STORE command or a SYSGEN system backup
       on DSSERVER.NET.SYS.

   *   There is a hardware problem - the communications device is not
       responding correctly.

Line Closing Errors 

There are several reasons why a DSLINE command for closing a
communications line might be rejected.  The following list summarizes the
likely causes of line closing failures:

   *   The user made a syntax error in the DSLINE command.

   *   The user specified an erroneous nodename or envid in the DSLINE
       command.  The nodename must match the one configured with NMMGR.
       Make sure that all users know the correct nodenames.  You may want
       to post a map with the configured nodenames for all the nodes on
       the network.

   *   The remote node may not be operational.

   *   There is a hardware problem - the communications device is not
       responding correctly.

NMS Utility Errors 

A file system error (FSERR) may have occurred while attempting to access
the configuration file.  Try to access the configuration file under the
same user ID using NMMGR. Use the NMMGR Error screen to find out what the
underlying FSERR is.  A complete listing of NMS error messages is
available in Using the Node Management Services (NMS) Utilities.  Correct
the problem and retry.
