Startup Sequence

To give the server the required information to pass along to the $ZSSI, alter the OBEY
file used to start $ZSVR to:

#FRAME

#PUSH #PARAM

DELETE DEFINE =TCPIP^HOST^FILE

ADD DEFINE =TCPIP^HOST^FILE, CLASS MAP, FILE $system.ztcpip.hosts

#SET #PARAM CSI^HOSTNAME hostname

ZSERVER/NAME $ZSVR,NOWAIT,PRI 199,CPU 2/6

#UNFRAME

Startup Sequence

Along with TCP/IP, $ZSSI also uses RPC services to communicate with the CSI. RPC
must be started to enable $ZSSI to communicate with the CSI. For more information
on RPC, see

Remote Procedure Call (RPC) Facility

on page 8-6.

This is a typical startup sequence as it relates to $ZSSI:

1. Start TCP/IP.

2. Start the portmapper. See

Running the Portmapper

on page 8-4.

RPC and the portmapper depend on TCP/IP.

3. Start $ZSVR.

$ZSVR creates the $ZSSI process when it is requested to communicate with the
tape library

$ZSSI cannot start processing requests until:

1. Connection through TCP/IP is made with the ACSLS library server.

2. Release 3.00 - Version 2 or later of the CSI process (program 300031) on the

ACSLS library server is ready and waiting.

To determine whether the CSI process on the ACSLS library server
TAPES.COMPANY.COM is up and running:

TACL 6>RPCINFO -t TAPES.COMPANY.COM 300031 2

CSI^CONNECT^AGETIME

Optional; # seconds connection aging (default 172800,
minimum 600, maximum 31536000)

CSI^RETRY^TIMEOUT

Optional; per try network interface timeout (default 3)

CSI^RETRY^TRIES

Optional; number of retries (default 5)

DEFINE name

Class

Description

=TCPIP^HOST^FILE

MAP

Optional; if present, the NonStop Kernel TCP/IP
software uses the HOSTS file specified by this
DEFINE to resolve the CSI hostname instead of
using the Domain Name resolver
