Hitachi Lightning 9900™ User and Reference Guide 57
Figure 4.3 shows a sample IOCP hardware definition for a 9900 with:
„
2105 ID.
„
Eight (8) ExSA™ (ESCON
®
) channels directly connected to the 9900.
„
Four (4) LCUs with 256 LVIs per control unit.
„
One (1) cu statement per logical control unit.
„
One hundred twenty-eight (128) 3390 base addresses per CU 0 and 1.
„
One hundred twenty-eight (128) 3390 alias addresses per CU 0 and 1.
„
Sixty-four (64) 3390 base addresses in CU 2.
„
One hundred ninety-two (192) 3390 alias addresses in CU 2.
„
One hundred twenty-eight (128) 3390 addresses in CU 3.
„
Sixty-four (64) 3390 base addresses per CU 3.
„
Sixty-four (64) 3390 alias addresses per CU 3.
„
To protect data integrity due to multiple operating systems sharing these volumes, these
devices require FEATURE=SHARED.
Note: If you maintain separate IOCP definitions files and create your SCDS or IOCDS manually
by running the IZP IOCP program, you must define each LCU on a 9900 subsystem using one
CNTLUNIT statement in IOCP. While it is possible to define an LCU on a 9900 subsystem using
multiple CNTLUNIT statements in IOCP, the resulting input deck cannot be migrated to HCD
due to an IBM
®
restriction allowing only one CNTLUNIT definition.
