Hardware Definition Using Hcd (Mvs/Esa); Hcd Definition For 64 Lvis - HP XP20000/XP24000 Operation Manual

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.

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
with more than 64 LVIs (see
