I got this problem that I don’t know if anyone else have.

Winservers (x2): Win2008R2, SQL 2008 cluster, sql installed on iSCSI drives (let say G & H I mapped them to)
DSS Machines (x2): 3ware Raid 6 (9650SE-16ML), Open-E, (and of course, I setup the LV for my SQL server)

The problem I keep running into is, I have a program that run restore databases to SQL server. After about 30min to 1hour, the iSCSI drives just disapear. After digging arround to see what the problem were, I nailed it down to the Raid card simply don’t see my hard drives anymore (this happened to 3 different Raid cards). After I shutdown the machine and power it up again, all drives are visible again.

When that happened, the auto failover did not failover (I've talk to Open-E support and they are working on that issue). The 3DM would take forever to open any page I try to open, all it tells me is "No Units", don't show firmware or serial number, nothing, unless I reboot the machine.

The Version of DSS I am running is 6.0up40.8101.4550 64 bit. The Raid card firmware is FE9X 4.10.00.007, Driver 2.26.08.006-2.6.28
