Controller Configuration
You can use RAID EzAssist to view a controller’s current configuration
settings. Additionally, you can change certain settings on your controller.
Each Mylex Disk Array Controller is shipped from the factory with default
settings which have been found to work well in a majority of applications
and environments. However, no two environments are the same, and you
may want to modify certain settings. The best time to make such changes is
prior to doing your first drive configuration on the controller.
This chapter will discuss the following:
• Viewing Controller Configuration Information
• Changing Global Properties
• Changing SCSI Transfer Properties
• Changing Startup Properties
The following table is a summary of the specific properties you are able to
change along with their default values.
Table 3-1. Summary of Controller Parameters
If you wish to view basic configuration information about the selected
Mylex controller, see the section called “How Do I View Controller
Configuration Information?” on page 3-2.
