We then received a confirmation that the new production IODF had been created. We
pressed F3 the number of times needed to return to the ISPF main menu.
We next used the ISPF editor to modify line 2 of member LOAD01 of SYS1.IPLPARM on
ZP4SYS, as shown in Figure 11-20. We changed the ‘07’ to ‘08’ so that at the next IPL the
system would use SYS1.IODF08, the IODF we just created.

We then IPLed the system to ensure that the osasna device was available to VTAM.
11.9 Defining the SSCPs, the subareas, and the network
Before the SSCPs can go into session, they must be named and assigned unique IDs.
Member ATCSTR00 of VTAMLIB contains the VTAM start options. We used the values from
Tables 1-3 to enter the values unique to each system. Every system must specify the same
NETID.
The VTAM starting member for system zos1 is shown in Figure 11-21 on page 168.

The values for SSCPID, HOSTSA, SSCPNAME, and HOSTPU came from the tables we
presented in “Selecting VTAM configuration information” on page 156 and “Developing the
adapter and device matrix” on page 156. We set NETID to an arbitrary string. The remaining
values are CBIPO defaults. The start members for the other systems are shown in
Figure 11-22 through Figure 11-26 on page 169.
