Hi All,
I can report, that I solved the issue, but it stays strange:
1. Downgrade of Intel S2400SC Board to BIOS Version based on HCL
2. Test after Reboot, not 10 GB Card detected
3. Load BIOS Defaults (btw. this was not the first time, I tried several times before, but without success)
4. Removed LSI Raid Controller (SAS9271-8i - latest FW) and installed 2 TB WD Disc an only activated the 2 onbard NICs
5. Install VMWare 5.1 without patches
6. Shutdown and insert the 10 GB Card
7. Card is there!
8. Shutdown and add RAID Controller
9. Reboot System from 2 TB Disk
10. RAID Controller, Partitions, and also the 10GB Kard is visible!
11. Shutdown and remove 2 TB Disk
12. Boot from old Installation on LSI RAID
13. 10GB Nic is still there.
I don't know what the root cause was. It stays strange, but I'm lucky that it is working now.
Wish you a nice Weekend.
