Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

a. Enter WHO at the TACL prompt:
> WHO
\HOME.$SYSTEM.SYSTEM 2> WHO
Home terminal: $ZTNP1.#PTYPRAB
TACL process: \HOME.$Z34A
Primary CPU: 2 (NSR-G)
Default Segment File: $SYSTEM.#0000382
Pages allocated: 24 Pages Maximum: 1024
Bytes Used: 32820 (1%) Bytes Maximum: 2097152
Current volume: $SYSTEM.SYSTEM
Saved volume: $SYSTEM.SYSTEM
Userid: 255,255 Username: SUPER.SUPER Security: "AAAA"
Logon name: SUPER.SUPER
The TELSERV process, $ZTNP1, is listed next to the HOME TERMINAL field. Make note
of the TELSERV process.
b. Check all TCP/IP processes to find the one that has your TELSERV process listed as an
opener. This is the process that you do not want to shut down.

c. Make a note of the CIPSAM processes (in this example, $TCPS3, $TCPS1, $ZTC01) so
that you can shut them down in your shutdown procedures (see “Stopping CIP” (page 116).
d. Issue a LISTOPENS PROCESS $process-name on each process listed in the display for
LISTDEV TCPIP until you find the process that is running the TACL prompt of your home
terminal.
The listing shows all the processes depending on $ZTC0:
> LISTOPENS PROCESS $ZTC0
Openers PPID BPID PLFN BLFN Protocol Lport
$ZPRP1 1,304 4 0 TCP echo
$ZPRP1 1,304 5 0 TCP finger
$ZPRP1 1,304 6 0 TCP ftp
$ZTN1 1,305 3 0 TCP telnet
$ZTSM 0,307 22 0 TCP 980
$ZCVP1 0,324 1 0 UDP 548
$ZPMP1 1,266 2 0 UDP 111
$ZPMP1 1,266 3 0 TCP 111
$ZTNP1 1,305 4 0 TCP telnet
$ZNET 0,21 2 0 #ZSPI *
In the Openers column, $ZTNP1 is an opener of the $ZTC0 process. In this example,
$ZTNP1 is the TELSERV process running our home terminal so you must make sure you
do not shut it down. If the process running your home terminal is a CIPSAM process, use
TELNET to connect to another TCP/IP process (conventional TCP/IP or NonStop TCP/IPv6)
if one is available. If you are not running an alternative TCP/IP subsystem, connect to
CLCI by using the OSM Low Level Link. (CLCI provides a primitive terminal emulation
when no other TCP/IP subsystem is available, but has limited functionality.)
2. Determine if any applications are using the CIPMONs and make a note of the application
names. Enter this command at the SCF prompt (a sample display follows this command):
The listing shows all the processes depending on the CIP subsystem:
