I am attempting to provision a couple of Dell Precision 690 workstations and am running into difficulty. It loads the WinPE image, but in starting the task errors saying it cannot see the drive. I have used this template on several other workstation models, including HP, Dell, and Lenovo machines without fail.
The difference, as far as I can tell, is that these boxes have a Dell SAS 5i integrated RAID controller. I assumed this to be my problem, and so downloaded the driver and added it to my WinPE image. I redeployed PXE reps and this still has not resolved this issue.
I also tried setting the SATA mode from AHCI to Legacy, as I have run into a similar problem on several machines with SATA drives. However, I am still unable to see the drives.
I know the drives and controller are working, because I can boot to the out-of-box image that Dell puts on the workstations.
I am running out of ideas, and thought I would put this out there to see if anyone has run into this issue before, and if they have any additional ideas to resolve it.
