HP NetRAID-4M Configuration and Upgrade Guide (Release 5)

Chapter 9 Issues and Problem Resolution
60
Resolution: Issue listed for information only. No action required.
52 Marathon not supported on Windows NT 4.0
Problem: The Marathon Technologies software architecture is geared towards
working with the standard Microsoft Class/PortMiniport driver stack. In Windows
NT 4.0, the NetRAID-4M has its own Class driver for RAID, which is incompatible
with the current Marathon Technologies software.
Workaround: Windows 2000 will be fully compatible because NetRAID-4M and
Marathon both use the same Windows 2000 Microsoft Class/Port/Miniport driver
stack.
53 Blue Screen with active directory enabled
Problem: Due to a coding error in the caching algorithm, the NetRAID-4M can lose
data when writing a very large number of small files at an extremely high data rate.
The problem has been seen only while converting Windows 2000 servers to Active
Directory, leading to corruption of the registry file and a blue screen on the next
boot. No problem was observed with any operating system other than Windows
2000, or if the controller cache is disabled, or if the Windows 2000 system partition
is on the server embedded SCSI or RAID, or if the server is not a domain controller.
Resolution: The firmware on all NetRAID-4M boards should be updated to level
3978 or newer.
54 Upgrading Windows 2000 NetRAID-4M driver
Problem: There is a problem upgrading the 4M's Miniport driver under Windows
2000. This issue is in two parts. Part one has to do with making a change to the folder
properties. Part two is concerning the use of the Windows 2000 Upgrade Device
Driver Wizard.
Impact to Customer: Customer may unintentionally fail to upgrade the 4M driver
even though customer goes through the proper steps.
Case 1: Device Driver Wizard may not see the new “hpn.inf” file due to default
folder options settings. We found that this is related to Microsoft's default
configuration. By default, the OS will hide all the known file extension for known
file types. We can do nothing about this. When you choose Have Disk in the Browse
window, you can see the .INF files there without file extension, but in the File Name
box, you can see the file with extension. This is confusing because the user might
not know the one in the Browse window is the one shown in the File Name box.
Either you must unhide the file extension or else pick the hpn.inf directly.
