HP StorageWorks XP Disk Array Mainframe Host Attachment and Operations Guide (A5951-96154, September 2010)

For information on supported versions, Linux kernel levels, and other details, 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 VOLID and 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 .
// EXAMPLE JOB
// EXEC PGM=ICKDSF,PARM=NOREPLYU
//SYSPRINT DD SYSOUT=A
//SYSIN DD *
INIT UNITADDRESS (XXXX) VFY(*NONE*) VOLID(YYYYYY) -
OWNERID(ZZZZZZZ)
/*
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
devices. The following table lists ICKDSF commands that are specific to the storage system, as
contrasted to RAMAC.
