an HBA card has the highest priority over other devices on a SCSI
bus.
Step 4.
Create redundant host paths.
In a mission-critical application,
redundant data paths to different LDs (logical drives) or logical
volumes (LVs) can be created. To do this, logical units (LDs or
LVs) are mapped to both host channels (CH0 and CH1 in
Figure 3-
4.
) This will ensure that if one host computer fails, the second host
computer will be able to access the logical units on that host
computer.
