Hi, Is there any way to allow 2 PCI-E sata controller on DS3617xs? I did one work perfectly by editing grub.cfg with "set extra_args_3617='DiskIdxMap=1000 SataPortMap=24'". However, when I add another sata controller and change grub.cfg to "DiskIdxMap=100005 SataPortMap=244'", all hard drives on sata controllers are gone. What's the correct expression for this situation? I have 3 drives on the old sata controller and 4 drives on new sata controller. Thanks!
