• 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 or ICP IOCP program, you must define each CU image on a storage system using one CNTLUNIT statement in IOCP. While it is possible to define a CU image on a storage system 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.

The HCD procedures for 3990 and 2105 controller emulation types are described as follows. FICON/zHPF interface requires 2105-F20 emulation or 2107. 3990 Controller Emulation: To define a storage system with 64 or fewer LVIs, use the same procedure as for an IBM 3990-6/6E storage system (see Table 10). The hardware definition for a storage system with more than 64 LVIs (see Table 11) is different than that for an IBM 3990 storage system.

Hardware definition using HCD (MVS/ESA)
The HCD utility can be used to define the storage system in an MVS/ESA environment. The HCD
procedures for 3990 and 2105 controller emulation types are described as follows. FICON/zHPF
interface requires 2105-F20 emulation or 2107.
3990 Controller Emulation:
To define a storage system with 64 or fewer LVIs, use the same procedure
as for an IBM 3990-6/6E storage system (see
Table 10
). The hardware definition for a storage system
with more than 64 LVIs (see
Table 11
) is different than that for an IBM 3990 storage system.
