The current RAID&nbsp;641 controller is connected to the 6 bay on the server, and the controller is sitting in Slot 3.</P><P>&nbsp;</P><P>We ordered a 642 controller and installed it into slot 5, when reboot the the drives that were on RAID 641&nbsp;moved to a different device number.</P><P>&nbsp;</P><P>I know that the device number on slot 3 is 2, and on slot 5 is 1, so I figured that is why the drive on the 641 had moved. So to the question is, if we moved the 641 controller to slot 5, and the 642 to slot 3 would it cause any issue with the RAID configurations we have?</P><P>&nbsp;</P><P>Thanks</P><P>&nbsp;</P> Wed, 01 Jun 2011 16:58:57 GMT SonosAdmin 2011-06-01T16:58:57Z https://community.hpe.com/t5/proliant-servers-ml-dl-sl/adding-a-second-raid-controller-in-linux/m-p/2386227#M125528 <P>Hello,</P><P>&nbsp;</P><P>I have an HP ML350 G4, that we installed a 2 bay drive cage.
