Initializing the LVIs

The 9900 LVIs require only minimal initialization before being brought online. Figure 4.21
shows an MVS ICKDSF JCL example of a minimal init job to write a volume ID (VOLID) and
volume table of contents (VTOC).
Note: HPAV base and alias devices require additional definition. For further information,
please refer to the Hitachi Lightning 9900™ Hitachi Parallel Access Volume (HPAV) User and
Reference Guide (MK-91RD047).
// EXAMPLE
//
//SYSPRINT
//SYSIN
INIT UNITADDRESS (XXXX) NOVERIFY VOLID(YYYYYY) -
OWNERID(ZZZZZZZ)
/*
Note: X = physical install address, Y = new volume ID, Z = volume ID owner.

Device Operations: ICKDSF

The 9900 subsystem supports the ICKDSF media maintenance utility. The ICKDSF utility can
also be used to perform service functions, error detection, and media maintenance. Since
the 9900 is a RAID device, there are only a few differences in operation from conventional
DASD or other RAID devices. Table 4.6 lists ICKDSF commands that are specific to the 9900,
as contrasted to RAMAC.
