During some tests done with ORION (10.2.0.1) on IBM x3950 server attached to IBM DS80000, I manage to repeatedly crash the server. It usually crashed at the end of 14h long test with ORION running in advanced mode. I decided to run Windows Update and install all fixes on top of Windows 2003 x64 SP2, plus update IBM Subsystem Device Driver Device Specific Module (SDDDSM) from version 2.1.3.0-1 to 2.4.1.2-2. Without a machine type number it’s close to mission impossible to find the driver on IBM web site. I guess they rearrange the site to be worse than it was a year ago when I needed SDDDSM. That’s the reason why I wrote down this note with the link to download section.
