We bought a HP DL140 02R X2.8/2M SCSI Server.Which has got a SCSI card on board,which doesn't support raid.
so we bought ML 150 SCSI Raid Controller . I unplugged the SCSI cable that is plugged onto the onboard SCSI card and plugged on the Raid controller.
When I boot the server, The server doesn't detect the raid controller. I am I doing any thing wrong.
