Using a 39160 with PERC 4 on Dell 1850
Hi guys,
I have a Dell 1850 with built in Perc 4 controller. It does not have any external SCSI ports and I need it to connect to a Dell 220S. I added an Adaptec 39160 card but now that I've added it, my PERC controller quit working. Is there any way to use both of these cards?
What I would like to do is have the PERC controller run the 2 onboard drives in RAID1 and have the 39160 run the 220S in (software) RAID5.
Any help will be greatly appreciated.
THANKS!!

I've had different models of Dells ship to me with both PERC & 39160 cards installed. But do to the internal wiring & backplane, you have to use the internal bays for the PERC, and use external enclosure for the Adaptec. You can't partition the backplane to use both. But the SCSI spec does say that it is a perfectly valid topology to chain two controllers and multiple drives onto the same parallel SCSI cable.
I.e PERC -> DISK -> ... DISKS -> ADAPTEC. Make sure that the two initiators are on unique SCSI IDs, along with everything else. You'd probably have to do something funky to deal with termination, as I don't have the backplane to look at, but electrically this would work. I've done this many times before with two adaptecs running in different systems to allow for sharing of disks between two hosts (with some custom software to avoid data corruption).
This is advanced stuff obviously, and won't be officially supported, but your question was IF there was a way, so the answer is yes.

Apparently there is some type of hardware issue. I tried changing the irq and it still didn't work. I put the card in a different 1850 and it worked without any changes.
Thanks
Thanks
Been a while since I've had to set IRQ's,but that probably the issue.
Also try moving the Adaptec around to a different slot.
