1Hardware path to /dev/mpt14.

2Device file for hardware path 1/0/14/0/0.

3Hardware path to /dev/mpt15.

4Device file for hardware path 1/0/14/0/1.

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
