Configuring and Using the 9900 Subsystem

Figure 4.2 shows a sample IOCP hardware definition for a 9900 configured with:

 3990 ID.

 Two (2) LPARs called PROD and TEST sharing 4 ExSA™ (ESCON®) channels connected via 2

ESCDs to the 9980.

 Each switch has ports C0 and C1 attached to the 9980.

 Four (4) LCUs with 256 LVIs per control unit.

 Two (2) cu statements per logical control unit.

 To protect data integrity due to multiple operating systems sharing these volumes, these

devices require FEATURE=SHARED.

IODEVICE ADDRESS=(A300,256),CUNUMBR=(A300,A301),UNIT=3390,FEATURE=SHARED

Note: 4096 device addressing requires 16 CU images using CUADD=0 through CUADD=F in the CNTLUNIT statement.
