Duplex 642 Controllers

[Craig Forster]

Hi, I have 2 642 controllers in our new dl380 g3. There is a seperate disk array with 2 scsi connectors. What i want to do is to use all the disks in both ports of the disk array to make one big logical drive, but that requires that both the 642 controllers be duplexed. When i go into ACU XE only the onboard 5i controller is listed. In Insight Manager agent there is a field in the 642 properties that says 'not duplexed'. Anyone how how to duplex, or do i need a special duplexing cable??

Thanks in advance folks!
