The device files for both channels of an A7173A adapter are listed in Example 3-11. Both channels
of the A7173A adapter share the same PCI slot. Their hardware paths are the same except for
the last digit. In the example, the SCSI channel associated with device file /dev/mpt14 is in use
and is connected to target devices on a SCSI bus. The SCSI channel associated with device file
/dev/mpt15 is not connected to a SCSI bus or to any target devices.
To view a summary of the SCSI parameter settings for a channel on an A7173A adapter, enter
the mptconfig <device_file> command, where <device_file> is the device file name
of an A7173A adapter channel. For example:
# mptconfig /dev/mpt14
