NOTE: For important details about each of the SCSI parameters that can be set online using the mptconfig command, see:

•“About SCSI IDs” (page 24)

•“About the Maximum Data Transfer Rate” (page 24)

•“About Bus Width” (page 25)

Using mptconfig for Online Configuration

The mptconfig command has options for changing each of the user-configurable SCSI parameters. By default, the SCSI ID of the A7173A adapter is “7,” the transfer rate is “ultra320” and the bus width is “wide.”

To see a help screen showing the mptconfig command syntax, enter mptconfig at the system prompt with no additional options:

#mptconfig

Usage: mptconfig [options] <dev_file>

<dev_file> = /dev/mptX

Options:

 

 

-i initiator_id =

0 to 15

-t target_id

=

0 to 15

-r rate

=

ultraultra2ultra160ultra320

-w width

=

narrowwide

-d set default values for scsi bus

default values

are:

initiator_id =

7

rate

=

ultra320

width

=

wide

Note:

 

 

-You must be a privileged user to execute this command. See privileges(5) for more information on privileged users.

-See mptconfig(1M) for tool details.

To use the mptconfig command you will need to know the device file name for each A7173A adapter you want to configure. Use the ioscan -kfncommand to determine the device file name for each A7173A adapter installed in your system. Example 3-11shows a portion of ioscan -kfnoutput that includes an A7173A adapter and a disk array that are on the same SCSI bus:
