[SunHELP] Fwd: StorEdge 3120 connection in HA environment:

[Yazid]

Info about scsi wiring:
 http://docs.sun.com/source/816-7956-10/ch04_cable.html#10046
 You need to set different scsi initiator id on the second host. Search
sunsolve to get the doc on how to set scsi initiator id, you probably need
contract access to get the document though.
