For HBA driver versions above Version x-4.53a7, this value is set automatically by the
Fibre Channel Software Setup included in this release of Solution Software.
For HBA driver Version x-4.53a7, this parameter must be set manually. For all
Windows configurations using this driver version, verify that the ResetTPRLO HBA
driver parameter is set to 1 by using the LPUTILNT utility. Use the following
procedure:
1. Choose Start and then Run.
2. Type
LPUTILNT and select the first HBA.
3. Select Driver Parameters in the Category pane.
4. Click Parameters.
5. Scroll down and double-click ResetTPRLO.
6. Set the value to 1.
7. Select Permanent and Global.
8. Click Change.
You need to follow this procedure for each HBA that uses Version x-4.53a7 drivers in
the system. If you use this method, you do not have to restart Windows after the
registry is modified. The ResetTPRLO parameter is dynamic.
See Customer Advisory OI020510_CW0x for additional information.
Registry Growth in Windows
The Windows plug-and-play architecture has a limitation on the number of
plug-and-play device entries that can be added to the registry. Whenever devices are
added or removed, or SNAPSHOT is created or deleted, entries are added to the
registry by the Plug-and-Play manager, potentially causing the registry to grow
beyond the allowed capacity.
If more than 700 entries are in the registry, the next time the system reboots for any
reason, the following error message occurs before the operating system boots up:
“Failed to load Windows 2000 due to a file missing or corrupt in the
\WINNT\SYSTEM32\CONFIG\SYSTEM directory.”
Please see the Microsoft Knowledge Base article (Q269075), which provides more
information about the registry growth problem.
