We have IBM X3400 M3 with SAS controller and and two disk with raid 1. We need extra space without protection. I try to add standart SATA disk to server. It has two SATA port on mainboard. When I connect SATA disk, it can't boot from SAS controller, try to boot from sata. I can't find any option in boot order for SAS controller. I try to adding SAS controller as boot device in bios but no solution.
I try to another option: buying PCIE 2.0 1x sata controller (IO-PCE9215-4I). This card hasn't got rom, only working in operation system. Amber light on near PCIE slot. I try to disable rom boot option and legacy mode for PCIE slot but no solution. System auto restart while detecting booteable adapter step.
I can't find detail about third party PCI Express sata controller or any PCI Express card working or not with IBM server.
I will making plan to test with PCI sata controller.
Is there any way to adding sata disk to this server without new IBM sas/sata controller?
