Configuration Examples

Figure 16 shows a two-way loosely coupled complex, TPFA and TPFB. OSA-Express connections have been defined by entering the ZOSAE command. Each TPF processor connects to the IP network through two OSA-Express cards. Each OSA-Express card connects to its associated Gigabit Ethernet (GbE) switch. Each TPF processor has one static VIPA. A movable VIPA (3.3.3.4) is defined on both processors but is owned by TPFA.

This environment was set up on TPFA by entering the following:

ZOSAE DEFINE OSA-TPFAOSA1 IP-1.1.1.1 MASK-255.255.255.0 PORT-OSAPORT1 READ-E00 DATA-E02
ZOSAE MODIFY OSA-TPFAOSA1 GATEWAY1-1.1.1.3 GATEWAY2-1.1.1.4 NET-GENET
ZOSAE DEFINE OSA-TPFAOSA2 IP-2.2.2.2 MASK-255.255.255.0 PORT-OSAPORT2 READ-722 DATA-725
ZOSAE MODIFY OSA-TPFAOSA2 GATEWAY1-2.2.2.8 GATEWAY2-2.2.2.6 PRIMARY-TPFAOSA1 NET-GENET
ZOSAE ADD OSA-TPFAOSA1 VIPA-3.3.3.3 STATIC
ZOSAE ADD OSA-TPFAOSA1 VIPA-3.3.3.4
 

This environment was set up on TPFB by entering the following:

ZOSAE DEFINE OSA-TPFBOSA1 IP-1.1.1.2 MASK-255.255.255.0 PORT-OSAPORT1 READ-806 DATA-804
ZOSAE MODIFY OSA-TPFBOSA1 GATEWAY1-1.1.1.3 GATEWAY2-1.1.1.4 NET-GENET
ZOSAE DEFINE OSA-TPFBOSA2 IP-2.2.2.26 MASK-255.255.255.0 PORT-OSAPORT2 READ-920 DATA-922
ZOSAE MODIFY OSA-TPFBOSA2 GATEWAY1-2.2.2.8 GATEWAY2-2.2.2.6 PRIMARY-TPFBOSA1 NET-GENET
ZOSAE ADD OSA-TPFBOSA1 VIPA-3.3.3.8 STATIC
ZOSAE ADD OSA-TPFBOSA1 VIPA-3.3.3.4

Note:
Figure 16 shows GbE networks. If you are using Fast Ethernet (FENET) networks, do the following:
  1. Replace the GbE switches with FENET hubs.
  2. Code NET-FENET to replace NET-GENET to define or modify the OSA-Express connections by entering the ZOSAE command with the DEFINE or MODIFY parameter specified.

Figure 17 shows VIPAs that have been swung from connection TPFAOSA1 to TPFAOSA2 on the TPFA processor by entering the following:

ZOSAE SWING OSA-TPFAOSA2
 

The ZOSAE command with the SWING parameter specified must be entered from the processor where the OSA-Express card exists.

Figure 18 shows a movable VIPA (3.3.3.4) that has been moved from processor TPFA to processor TPFB by entering the following:

ZVIPA MOVE VIPA-3.3.3.4 CPU-B

The ZVIPA command with the MOVE parameter specified can be issued from any processor in the loosely coupled complex.
