I have a Dell PowerVault 210s. I added 3 x 36.4 drives to it. There are two SCSI ports on the PowerVault chasis. One of the SCSI ports is plugged into a Dell 2500 with a Perc/DC controller. The other port is plugged into a HP ML350 raid controller. The HP is using a 5300 raid controller. The server plugged into the second SCSI port cannot see the 3 new drives. Should I be able to split the backplane of a PowerValt 210s between two servers? Or, should I only split the backplane using one server?
