IOCP definition considerations: If you maintain separate IOCP definitions files and create your
SCDS or IOCDS manually by running the IZP IOCP program, the following definition rules
apply:

Each LCU on a storage system is defined using one CNTLUNIT statement in IOCP. The
unit type is 2105 or 2107 (only 2107 is available if you use XP Compatible Hyper PAV).
Up to 16 LCUs can be defined on a storage system. An LCU is identified by its LCU
Address (CUADDR=x parameter) and is specified as a hexadecimal number in the range
of 0 to F. An LCU is the same as an IBM Logical Sub-System or LSS. While it is possible
to have an LCU on a storage system defined using multiple CNTLUNIT statements in IOCP,
the resulting input deck cannot be migrated to HCD due to an IBM restriction to allow
only one CNTLUNIT definition.

Up to 256 devices may be defined on each LCU. Base device addresses are identified
as unit type 3390B or 3380B. Alias device addresses are identified as 3390A or 3380A.

HCD definition considerations: If you use HCD exclusively to define I/O definitions to z/OS
and OS/390 and to automatically run the IOCP program to create SCDS or IOCDS, the
following definition rules apply:

Each LCU on a storage system is defined as a 2105 or 2107 LCU (only 2107 is available
if you use XP Compatible Hyper PAV).

Base devices are defined as 3390B or 3380B device types. HCD will only allow you to
connect base devices to one LCU. Base device optional parameter definitions in HCD
include the WLMPAV=xxx parameter. The default setting is YES.

Alias devices are defined as 3390A or 3380A device types. HCD will only allow you
to connect alias devices to one LCU. Alias devices have only one optional parameter
definition in HCD. The WLMPAV=xxx parameter defaults to YES.

Administrator access to the Remote Web Console computer is required to perform Compatible
PAV operations. Users lacking administrator access can only view Compatible PAV information.

The WLMPAV parameter value is not relevant when using XP Compatible Hyper PAV.

Remote Web Console computer:

The Remote Web Console computer must be installed and attached to the storage systems
via the storage system internal LAN (see

“Configuring your Remote Web Console

Computer” (page 19)

).

The Remote Web Console software must be installed, and the Compatible PAV options
must be enabled on the Remote Web Console computer (see

“Enabling the Compatible

PAV Option” (page 19)

).
