HP StorageWorks XP Disk Array Mainframe Host Attachment and Operations Guide XP24000, XP20000 (A5951 - 96151, September 2007)
enables high levels of concurrent data access across multiple channel paths. For further information
on TPF and MPLF operations, see the IBM documentation.
Note on 2105 emulation:
There are available PTFs to implement exploitation mode for TPF version
4.1. For further information, see the IBM documentation.
Defining the Storage System to Mainframe Linux
The storage system supports attachment to the following mainframe Linux operating systems:
• Red Hat Linux for S/390 and zSeries
• SuSE Linux Enterprise Server for IBM zSeries (contact HP for availability)
For information on supported versions, Linux kernel levels, and other details, contact your HP
representative.
For details on FICON connectivity, FICON/Open intermix configurations, and supported FCAs,
switches, and directors (for example, McDATA or CNT) for the storage system, contact your HP
representative.
For information on preparing the storage system for Linux host attachment, see the IBM publication:
Mainframe Operations
Initializing the LVIs
The storage system LVIs require only minimal initialization before being brought online. The following
shows an MVS ICKDSF JCL example of a minimal init job to write a volume ID (VOLID) and volume
table of contents (VTOC).
NOTE:
PAV base and alias devices require additional definition. For further information, see the
HP StorageWorks XP24000/XP20000 for Compatible Parallel Access Volumes Software User's Guide

/*
XXXX = physical install address, YYYYYY = new volume ID, ZZZZZZZ = volume ID owner.
Device Operations: ICKDSF
The storage system supports the ICKDSF media maintenance utility. The ICKDSF utility can also be
used to perform service functions, error detection, and media maintenance. Because the XP disk array
is a RAID device, there are only a few differences in operation from conventional DASD or other RAID
