compaq enclosure DS-SL13R-AA with dual scsi ultra 3.

When I connect this enclosure with a dual adapter card I only get 7 of the slots to work, unless I use to cables from each port to 2 cards for 14 disk to show up. I am using a SE SCSI adapter on Alpha 4100 server side. is there a way to get this shelf to work with all 14 disk and only use one adapter on the server end? When I use a single scsi card all 14 disk show up.

Works as designed.

The dual-port I/O module does not join both busses in the box. If you want to dedicate a single SCSI bus from the server for the entire box, you do need to use a single-bus I/O module.

Thank You very much, I wished I had asked this question yesterday, before my 4 hrs of trouble shooting and PD, and changing whatever I could. Now I will place this to rest and order another single port.
