2.5 Driver Levels of the HDLM and MPIO Drivers
The HDLM and MPIO drivers are positioned at a higher driver level than the SCSI
drivers. In other words, applications that are accessing LUs in storage systems will first
use the HDLM and MPIO drivers, and then use the SCSI drivers, in order to access the
LUs.
Figure 2-6: Driver Levels of the HDLM and MPIO Drivers shows the driver levels
of the HDLM and MPIO drivers.
