Considerations for the PRIMARY Command
Considerations for the PRIMARY Command
•
If the specified CPU is not the CPU of the backup process, X25AM rejects the
command.
•
A non-error completion of the PRIMARY command indicates only that the
subsystem was able to initiate processing for the PRIMARY operation. It does not
necessarily indicate that the operation completed successfully.
•
When using Parallel Library TCP/IP the system manager can force a switch of the
processor or PATH (but not at the same time). To switch the processor (but not the
PATH) use the PRIMARY PROCESS command for X25AM.
•
For Conventional TCP/IP, standard IOP, and TCP/IP configuration (IOP primary,
backup processes, and TCP/IP – ALT TCP/IP processes configured on the same
CPU pair), the PRIMARY command switches the processor to the backup process
and simultaneously switches the PATH.
For other configurations of IOP and TCP/IP, the behavior might be different. The
CONMGR takes decisions on the path to use regardless of the request sent by the
IOP. In this case, a processor switch occurs but the PATH switch might not.
START Command
The START command initiates the operation of an object. The successful completion
of the START command leaves the object in the STARTED state. This is a sensitive
command.
To start an X25AM line for the first time, you must first issue the SCF START DEVICE
command to the WAN subsystem. Refer to the Task 6: Start an X25AM I/O Process on
page 3-8.
After the I/O process is started, you can start the line that it controls using the START
LINE command to the X25AM subsystem.
Command Syntax for the START Command
Syntax:
OUT file-spec
causes any SCF output generated for this command to be directed to the specified
file.
START [ / OUT file-spec / ] [ LINE line-name | SU su-name ]
