Hi Som, If your iscsi target doesn't support ALUA, you need check whether your iscsi target can match any one of failover operation types solaris supports. Solaris supports asymmetric/symmetric EMC failover operation, LSI asymmetric failover operation, sun standard symmetric failover and sun standard asymmetric failover operation, 5 types failover operation. Except sun standard symmetric failover types (ALUA), other types match fops by vendor ID and product ID. If your iscsi target cannot match to any type of failover operation set, the mdi_pi_online() always fail. So I think you need make sure the type of your iscsi target, then let we see whether you need add your vendorID and product ID to any specific fops for matching. If you debug more deeper, you would find the mdi_pi_online fails at *sfo_device_probe() routine of struct scsi_failover_ops.
