WAN Subsystem Problems
Check the state of the default
Subsystem Control Point (SCP)
manager process ($ZNET).
To determine if $ZNET is running, use this
command at the TACL prompt:
STATUS $ZNET
Typically, there should be a permanent SCP
process called
$ZNET on each Integrity NonStop
server that SCF uses by default. If $ZNET is not
running, SCF starts its own SCP process (which is
removed when SCF is stopped).
Check the state of each NonStop
TCP/IP pro
cess used by the WAN
subsystem.
To determine if the NonStop TCP/IP processes are
running, use this SCF command:
STATUS PROCESS $proces
s_name
To display the dynamic state of the TCP/IP
SUBNET
s, use this SCF command:
STATUS SUBNET $process
_name.*
If the NonStop TCP/IP processes are not running,
they must be st
arted. See the WAN Subsystem
Configuration and Management Manual.
Check the state of the Trivial File
T
ransfer Protocol (TFTP) server
process assigned to each NonStop
TCP/IP process.
To determine if the TFTP server processes are
running, use this SCF command:
STATUS PROCESS $ZZWAN.#ZFnnn
If the TFTP server processes are not running, they
must be st
arted. See the WAN Subsystem
Configuration and Management Manual.
Check the state of the WANBoot
pro
cess assigned to each NonStop
TCP/IP process used by the WAN
subsystem.
To determine if each WANBoot process is running,
use this SCF command:
STATUS PROCESS $ZZWAN.#ZWnnn
If the WANBoot processes are not running, they
must be st
arted. See the WAN Subsystem
Configuration and Management Manual.
Check the state of the concentrator
manage
r (ConMgr) process in each
processor where a WAN input-output
process (IOP) will run.
To determine if the ConMgr processes are running,
use this SCF command:
STATUS PROCESS $ZZWAN.#n
ConMgr processes are configured with the number
of the
processor they are to run in. For example,
$ZZWAN.#0 runs in processor 0.
If the ConMgr processes are not running, they
must be started. See the WAN Subsystem
Configuration and Management Manual.
