86 MSA1000 Installation Guide
6. Use the SCSI CAM Utility program (SCU) to download the MSA1000
firmware to the right controller.
There are three steps to download the firmware: (a) setting the device nexus
information, (b) determining which bus/target/LUN values to use, and
(c) downloading the firmware.
a. Use the scu sbtl command to set the device nexus information.
The scu sbtl command is a shorthand command for the set nexus
command.
To start the SCU, enter the following command:
/sbin/scu
At the scu> prompt, enter one of the possible bus/target/LUN
combinations that you recorded in step 6.
sbtl 5 1 0
Device:MSA1000, Bus:5, Target:1, Lun:0, Type:Array Controller
b. Use the scu tur command to determine if that bus/target/LUN
combination can be used. The scu tur command is a shorthand
command for the test unit ready command.
At the scu> prompt, enter the following:
tur
If an error message is displayed, go back to step a and use one of the other
possible bus/target/LUN combinations.
If the scu prompt is displayed with out an error message, proceed to the
next step.
c. Download the firmware from the file you copied to your system.
Make sure that you include the save and segment parameters.

The scu utility counts down from 120 seconds, returning to the scu>
prompt when the time delay is complete.
d. When the scu> prompt is redisplayed, enter the exit command to exit the
SCU.
