LD, SYSTEM_MGMT, Logical Disk Driver

LD allows you to create a logical (software emulated) disk device
of a user-specified sizes using backing storage from a disk file; 
it is a form of partitioning.   These logical disks can then be 
used for various purposes, including as staging areas required as
part of mastering CD or DVD media on OpenVMS; as part of using 
recording tools such as CDRECORD (versions are build into V7.3-1
and later, and versions are available for download from various
sources), or the COPY/RECORDABLE_MEDIA command found in V8.3 and
later.

This LD V8.2 kit and its contents are not supported by HP OpenVMS
Engineering.

This is an update to the versions of the LDDRIVER logical disk
device driver kit found on previous Freeware releases, this kit 
installs on OpenVMS Alpha V7.2-2, V7.3, V7.3-1, V7.3-2 and V8.2, 
on OpenVMS IA64 V8.2 and V8.2-1, and on OpenVMS VAX V7.3.

This PCSI installation kit supercedes all LDxxx VMSINSTAL kits, and
the V8.0 and V8.1 PCSI installation kits.

OpenVMS Alpha V8.2 and later, and OpenVMS IA64 V8.2 and later, have 
integrated support for LD.   This kit will update the installed version
of LD to the latest version.  (Formal LD ECO kits may contain newer
software, however.)

Releases OpenVMS Alpha V7.3-1 and later do have all necessary pieces
of LD latent, but the LD command verb is not registered in DCLTABLES by
default prior to V8.2.  Please see SYS$MANAGER:CDRECORD.COM for related
details.)

This kit may or may not operate on releases older than OpenVMS Alpha
V7.2-2, nor on releases earlier than OpenVMS VAX V7.3.  It may however
be possible to build it from the included sources for these releases,
please see the included release notes for details.

Releases LD063 and prior have a hard upper volume size limit of four
gigabytes (4 GB), and larger volumes should not be configured.  This
kit, as well as the integrated LD implementation available in OpenVMS
Alpha and OpenVMS I64 V8.2 and later (and potentially also the most
current LD ECO kits for V7.3-2, if any), do not contain this volume
capacity limit.
