4250 Storage works problem

I have a 4250 storage works enclosure ( 2 scsi ch x 5 disks in each ch ) I have an EMU & Duplex I/O module.
The problem is I cannot "see" disks on one of the scsi channels until the EMU is removed !
When the EMU is removed all seems ok

I have swapped scsi cables , psu's etc but its always the disks on the same channel that I cannot detect. I have replaced the EMU but the fault remains.
I am assuming a harware fault as it has worked correctly in the past but which component would seem to be the best bet ?

Re: 4250 Storage works problem

Do you have anything plugged into the back of the EMU?
The truth is out there, but I forgot the URL..
