You can use ISMF to examine
and manage the characteristics of your
data stored on DASD volumes. Eight line operators are available to
perform the following media maintenance tasks:
- Inspect a subset of a volume for magnetic surface defects.
ISMF
also provides options to help you remedy the problem.
- Examine
a drive and your data to determine if errors exist. This
function helps you distinguish between errors caused by drive problems
and errors caused by media problems.
- Initialize a DASD volume
for use in an MVS system.
- Change the volume label of a DASD
volume. You can specify a new
volume serial number or a new owner ID.
- Generate a job stream
that is used to change a volume from a nonindexed
format VTOC(OSVTOC) to an indexed format VTOC(IXVTOC) or vice versa.
- Reset a device that has been write inhibited, reset an indefinite
status condition, or clear a fence status of a path, a device, or
both.
- Generate a job stream that is used to perform the procedures
necessary
for installation, head-disk assembly (HDA) replacement, and physical
movement of IBM® DASD.
- Perform
the track validation functions of medial initialization
with the problem determination and data verification functions of
the ANALYZE command, and also the INSPECT functions if required.
For information on the ICKDSF functions that ISMF uses
to perform
these functions see Device Support Facilities (ICKDSF) User's Guide and Reference.
