Expand-Over-IP Problems
Resolving Expand-Over-IP Connection Problems
If the SCF STATUS LINE, DETAIL command displays CONNECTING in the Detailed
State field, use the SCF STATS LINE command to obtain more information about the
problem. Example 20-8 shows an SCF STATS LINE command.
If the line is configured to issue active connect requests, determine if Connect
Command frames (Conn Cmd column) are being sent (Send row). If the line is
configured in passive connect mode, determine if Connect Command frames (Conn
Cmd column) are being received (Rcvd row). If no Connect Command frames are
being sent or received, the destination line-handler process can not be operational or
there can be a network problem.
If the Invalid Frames Rcvd counter is greater than 0, frames are being corrupted;
contact your HP support representative.
If the Invalid IP Addr Rcvd counter is greater than 0, the Internet Protocol (IP) address
configured for either the local or destination Expand-over-IP line-handler process can
be invalid. Use the SCF INFO LINE command with the DETAIL option to display the
configured IP addresses and associated NonStop TCP/IP process. Example 20-9
shows an SCF INFO LINE command display
. (The relevant fields are shown in
boldface type.)
SOCKET_SPACE This is an internal state that should
not persist.
Try to restart the line. If this
state persists, contact your HP
representative.
WAIT The Expand-over-IP line-handler
pro
cess is waiting for another
process or subsystem.
The line remains started but is not
rea
dy for data transfer.
For more specific error
in
formation, see the Detailed
Info field. Recovering from
these types of problems is
described further in
