Presenting from EVA to WinNT 4.0 server

[Tom Bruce_1]

Just a quick question....

Any issues with presenting EVA Luns to a WinNT 4.0 server? I heard there are some little issues but wasn't told what they are.
Just need one disk presented for data copy and that is it.

Thanks in advance

Yes, here is what the release notes say:

""Operation on Microsoft Windows NT 4.0

The EVA v3.020 incorporates a new Critical Resource Management function that will send Queue Full responses to SCSI commands before the maximum allowable Queue Depth of 2048 has been reached for a Fabric Port.

It is strongly recommended to run homogeneous Windows NT 4.0 environments and not mix Windows NT 4.0 hosts with hosts running any other operating systems on a given EVA subsystem.

Windows NT 4.0 does not properly handle these queue full responses and I/O errors may result. The Critical Resource Management feature can be disabled by selection a Custom Host Mode for NT 4.0 hosts. This is accomplished by entering the value 000000041F80B8A8 into the Custom mode number window on the Add a Host page of Command View EVA. However, note that the action of disabling the Critical Resource Management feature affects the entire array.""

Same for VCS 3.025

ALthough it is always recommended to drive as specified in the manual....
I have a couple of EVAs VCS3.020 with NT 4 machines and other OSes. I didn't configure the NT servers the way the Release Notes says (as posted by Uwe), almost a year working ok.

So anything special I should look out for?
Any extra parameters need to be set?
