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
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.
