Expand-Over-IP Problems
You can diagnose most Expand-over-IP line-handler process problems using
information provided by the Expand subsystem SCF STATUS LINE command with the
DETAIL option. This command provides error information in the Detailed State and
Detailed Info fields. Example 21-7 shows an SCF STATUS LINE, DETAIL command
display. (The Detailed State and Detailed Info fields are shown in boldface type.)

Detailed State Cause/Effect Recovery
BINDING The Expand-over-IP line-handler
process is binding to the local
NonStop TCP/IP process.
This state is normal while the line is
coming up. If the line remains in
this state, an internal error may
have occurred.
If this state persists, contact
your HP support
representative.
CONNECTED A connection has been established. This state is normal. No
recovery is required.
CONNECTING The Expand-over-IP line-handler
process has connected to the local
NonStop TCP/IP process is and is
now attempting to connect to the
remote Expand-over-IP line-handler
process.
This state is normal while the
connection is being established. If
the line remains in this state, the
remote Expand-over-IP line-handler
process may not be operational or
there may be a network problem.
Use the SCF STATS LINE and
SCF INFO LINE commands to
further diagnose the problem.
These commands are
described in Resolving
Expand-Over-IP Connection
Problems on page 21-22.
