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

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.
