I have a PE2650 with PERC4 installed. The PERC is connected to a PV220s. The enclosure powers up and all drives spin up. When I use CTRL+M to configure the PERC, the PERC does not show any physical disks present in the 220s. When the PERC is scanning the SCSI channels I see it blinking the lights on the disks. The 220s is in shared bus mode with 14x300Gb drives connected. Suggestions?
