Hello,I'm working with a t4 and an ST3320
I was not able to find an exact procedure on how to:
- configure a single raid 1+0 LD with all the 12 disks;
- mapping it to the same hosts on both channel 1 and channel 3
- having mpxio to manage a multipath towards this single lun.
Following the only document I found ( http://unix.business.utah.edu/doc/hardware/sun/Manuals/3310_Manuals/redundant_3310.txt) with suggestions (together with old st3320 documentation) I was able to:
0- configured the Array in split bus .

1- Assign both controllers to both host SCSI channels to have eventually:
Channel 1, ID 0 & 1 (primary & secondary controller) Channel 3, ID 1 & 0 (secondary & primary controller)
