Hi all If there is a system with a scsi disk and two scsi adaptar, then is it possible to perform IO operation on the same scsi disk using both the adapter. To my understanding: *Each Scsi Adapter(HBA) can control one or more SCSI buses. *Each Scsi bus can have multiple SCSI devices connected to it. i.e a single scsi adapter control all the devices connected to a single bus. please correct me if i am wrong.
