Plain-text description of the adapter
Example 1-1 shows a system with two A7173A adapters installed. The ioscan output
indicates that the adapters have been claimed by the mpt driver. Notice the hardware path
shown in the second column. The A7173A adapter supports two PCI devices or functions
(one per channel). Two lines are listed for each A7173A adapter: one for channel A (denoted
by a 0 as the last digit in the hardware path), and one for channel B (denoted by a 1 as the
last digit in the hardware path). The device file for each channel of each installed adapter is
shown on the second line of each listing; for example, /dev/mpt6.
