WAN Subsystem Problems
Check the state of the default
Subsystem Control Point (SCP)
manager process ($ZNET).
To determine if $ZNET is running, use the
following command at the TACL prompt:
STATUS $ZNET
Typically, there should be a permanent SCP
process called $ZNET on each NonStop S-series
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 process used by the WAN
subsystem.
To determine if the NonStop TCP/IP processes are
running, use the following SCF command:
STATUS PROCESS $process_name
To display the dynamic state of the TCP/IP
SUBNETs, use the following SCF command:
STATUS SUBNET $process_name.*
If the NonStop TCP/IP processes are not running,
they must be started. See the WAN Subsystem
Configuration and Management Manual for details.
Check the state of the Trivial File
Transfer Protocol (TFTP) server
process assigned to each NonStop
TCP/IP process.
To determine if the TFTP server processes are
running, use the following SCF command:
STATUS PROCESS $ZZWAN.#ZFnnn
If the TFTP server processes are not running, they
must be started. See the WAN Subsystem
Configuration and Management Manual for details.
Check the state of the WANBoot
process assigned to each NonStop
TCP/IP process used by the WAN
subsystem.
To determine if each WANBoot process is running,
use the following SCF command:
STATUS PROCESS $ZZWAN.#ZWnnn
If the WANBoot processes are not running, they
must be started. See the WAN Subsystem
Configuration and Management Manual for details.
Check the state of the concentrator
manager (ConMgr) process in each
processor where a WAN input-output
process (IOP) will run.
To determine if the ConMgr processes are running,
use the following 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 for details.
