3.4 ICKDSF
Once the 9393 is installed and the functional devices are defined on the operator
panel (see Appendix A, “RVA Functional Device Configuration” on page 41) the
only initialization needed for the RVA functional devices is a minimal init,
ICKDSF INIT, with the additional parameters needed to define the VOLID and the
volume table of contents (VTOC) size and location. The CHECK parameter is not
supported, because surface checking is not needed on an RVA. Other ICKDSF
functions for surface checking, such as INSTALL or REVALIDATE, also are not
supported for the RVA.
The RVA internally uses FBA disk drives with internal data error recovery, so
surface checking in this way is inappropriate. If a media surface check is
needed, the IBM service representative can do this on the maintenance panel.
ICKDSF Release 16 with applicable PTFs is needed to support the RVA. To run
the VSE version of ICKDSF in batch mode, submit a job with an EXEC ICKDSF job
control statement.
3.4.1 Volume Minimal Init
In the example in Figure 4 a volume is initialized at minimal level under VSE. A
VSE format VTOC is written at cylinder 32, track 0 for a length of 20 tracks. The
volume is labeled 338001.

// ASSGN SYS002,151
// EXEC ICKDSF,SIZE=AUTO

3.4.2 Partial Disk Minimal Init
In the example in Figure 5, an emulated partial disk is initialized under VSE. A
VSE format VTOC is written at cylinder 0, track 1 for a length of one track. The
volume is labeled AA3380.
