Hardware Problem 6
The Gateway-ST loads, but the circuit remains in the on-starting state.
Solutions:
The solutions outlined in this section cover possible hardware and software
problems.
1.
Use the following command to check which line is associated with the
circuit:
SNANCP> SHOW CIRCUIT SDLC-
n CHARACTERISTICS
Use the following command to check the state of the line:
SNANCP> SHOW LINE SYN-
n
To turn the line on, use the following command:
SNANCP> SET LINE SYN-
n ON
2.
Check that the IBM line and PU are active. See the IBM system manager.
3.
Check that you completed Part 2 of the SNACST$CONFIGURE.COM
procedure and that the following file was created:
SYS$COMMON:[SNA$CSV]SNAGATEWAY__gateway-node-name_SNA.COM
4.
Check the IBM parameters against the values specified in the DECnet SNA
Gateway-ST Guide to IBM Parameters. In particular, make sure the NRZI
setting for the IBM NCP LINE macro is the same as the NRZI setting in
the Gateway-ST configuration file.
The following table equates Gateway-ST and IBM NCP NRZI settings:
