Host considerations Windows 2000 and Windows Server 2003 notes Drive-letter remapping can occur in the following situations and it can affect access to data by programs you may need to run: • Replacing one server with another. • Replacing an FC HBA in one of your systems. During such a system or adapter changeover, be sure to manually remap drives to drive letters using Disk Manager. This restores proper access to your data. When you replace an FC HBA in a server, you need to reinstall the HBA driver. Windows 2000/Windows Server 2003 automatically reloads the original driver for this adapter and resets many important registry settings. New connections are created on the HSV controller. Assign the new WWNs to the appropriate host. Upgrading from Windows NT 4.0 to Windows 2000 or Windows Server 2003 If you are upgrading from Windows NT 4.0 to Windows 2000 or Windows Server 2003, you must remove the software components installed by the previous version of the Fibre Channel Setup utility: 1. Start the existing version of the Fibre Channel setup utility, and follow the procedures to remove components. Alternatively, you can use the Add/Remove Programs applet. 2. Upgrade from Windows NT 4.0 to Windows 2000 or Windows Server 2003 as instructed by Microsoft® documentation. 3. Reboot. 4. Install the HBA driver upgrade as instructed in the HP SANworks Windows NT/Windows 2000 Kit V2.0 for Enterprise Virtual Array. 5. Run the Fibre Channel Setup utility. Registry growth in Windows The Windows plug-and-play architecture limits the number of plug-and-play devices that are added or removed from the registry. Whenever devices are added or removed, or snapshots are 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, the following error message appears: Failed to load Windows 2000 due to a file missing or corrupt in the \WINNT\SYSTEM32\CONFIG\SYSTEM directory. Refer to the Microsoft Knowledge Base article (Q269075), for more information about the registry growth problem. Known limitations for large LUNs for Windows 2000 In Windows 2000, if any LUN greater than 7 is removed and a subsequent disk scan is performed, the Found New Hardware wizard may ask you to finish the installation of the device that was removed. The Device Manager may show the device with a yellow warning icon on it. A reboot of the system removes the device.
