which it is assigned. An alias device must be defined to the host as a 3390A or 3380A device
type (for example, 3390A 3, 3390A 9).

The 3390A and 3390B devices are not related to the 3390-3A/B/C multiplatform devices.
Also, the 3380A and 3380B devices are not related to the 3380-3A/B/C multiplatform
devices.

Controller Emulation Type

The IBM 2105 or 2107 controller emulation type is required for Compatible PAV operations. Each
LCU image on the XP24000/XP20000 disk array which contains Compatible PAV base and alias
devices must be set for 2105 or 2107 controller emulation. If you use XP Compatible Hyper PAV,
only 2107 controller emulation type is available.

To configure copy devices and Compatible PAV devices under the same LCU image, see

“Requirements and Restrictions for Compatible PAV” (page 17)

for important information and

instructions. Copy devices include Hitachi TrueCopy™ for Mainframe, Universal Replicator for
Mainframe, Peer to Peer Remote Copy (PPRC), and Concurrent Copy (CC) devices.

Compatible PAV Software and License Key

The Compatible PAV Remote Web Console software enables you to configure the Compatible PAV
devices on the storage systems attached to the Remote Web Console computer. The Compatible
PAV displays the LDEVs in use as well as the unassigned LDEV IDs which are available for use as
aliases, and allows you to assign aliases to base devices and cancel aliases.

Before you can use XP Compatible Hyper PAV, you need to acquire the licenses for both Compatible
PAV and XP Compatible Hyper PAV.

The Remote Web Console computer is attached to and communicates directly with the storage
systems via the storage system internal LAN. For further information on the Remote Web Console
computer, see the HP StorageWorks XP24000/XP20000 Remote Web Console User Guide.

To use XP Compatible Hyper PAV, you need both Compatible PAV software and XP Compatible
Hyper PAV software.

The Compatible PAV will not function for a storage system which does not have the Compatible
PAV option enabled on the subsystem. When enabling the Compatible PAV option, you need a
license key (see

“Enabling the Compatible PAV Option” (page 19)

).

HCD Definitions for the Compatible PAV Devices

The Compatible PAV base and alias devices on the storage system must be defined in the IOCDS
using HCD. The storage system base devices must be 3390B or 3380B devices (for example,
3390B-3), and the storage system alias devices must be 3390A or 3380A devices (for example,
3390A-3). The required controller emulation for each storage system LCU image which contains
Compatible PAV devices is 2105 or 2107 emulation. (only 2107 controller emulation is available
in case of using XP Compatible Hyper PAV).

“Using HCD to Define and View Storage System

Logical Control Units and Compatible PAV Devices” (page 51)

provides sample instructions on

using HCD to define an Compatible PAV device.

The 3390A and 3390B devices are not related to the 3390-3A/B/C multiplatform devices. Also,
the 3380A and 3380B devices are not related to the 3380-3A/B/C multiplatform devices.

For further information on defining Compatible PAV devices to the zSeries and S/390 host, see
the following and other IBM documents:
