DLA Engine Installation

The DLA engine attempts to update all DLA engine drivers to be the same. These
drivers are the file system engine drivers and have nothing to do with the actual
device drivers from the shared components team. There are two complex issues with
this. The first is to be certain that all of the engine drivers are the new versions. The
second is to make certain that all of the PCONFIG data gets combined into one file.

Each installation has a PCONFIG file. This file indicates what devices are supported
for DLA. However, as a new version of DLA is installed, new devices may be supported
and this needs to be updated. As a version of DLA is uninstalled, some devices may
disappear from the support list while others remain from another installation.

All of this is handled by DLAUNIN.EXE. The normal installer calls “DLAUNIN.EXE –Q
–I –D:” where –Q means quiet mode, -I means install, and –D indicates the
directory to install from where is the directory. Only 1 version of DLA can
be installed on a machine. This is a new feature of the MSI installer

Shared Components Installation

The shared components (drivers used by all products including backup) are handled
by the basic installer. Each component is updated to make certain that only the
newest version is installed. A helper file (PNPWTAPE.EXE for Win9X or PNPNINST.EXE
for NT) handles the plug and play driver installation. This installation is the same
basic installation we use on all products.

Registry

DLA install settings are stored in the registry in
MyComputer\HKEY_LOCAL_MACHINE\Software\VERITAS\Direct
Access\CurrentVersion\All

DLA driver settings are stored in the registry in
MyComputer\HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\* (* =

NOTE:

These settings should not be altered by the user.
