Users Guide

When a controller is created, a default variable condition, array and disk(s) are created to ensure a valid configuration.
You can choose to leave the controller un-configured with disks set to non-RAID, or you can add arrays or perform other
actions.
Defining Rules With the Array Builder
You can define rules to match configurations based on the following:
• Detected slot number that the controller is in or just the embedded controller, if any.
• Number of disks that are attached to the controller.
• Apply a blanket configuration to any controller the Array Builder finds.
You can also apply configuration rules based on the RAID profiles detected on the server. This allows you to define
different configurations to different servers even if the detected hardware is identical.
Creating a RAID Profile Using Array Builder
To create a RAID Profile:
You can also import an existing profile and modify the configurations using the Array Builder. For more information on
importing a profile, see Importing a Profile.
1. Launch the System Viewer utility, click RAID Configuration → Create RAID Profile.
When you launch the Array Builder, a default embedded controller is created.
2. Type the configuration rule name in the Configuration rule name field.
3. Select the Error handling rule from the drop-down menu. You can choose from:
• Fail the task if any controller does not match a configuration rule — Reports a failure if any of the detected
controllers are not configurable by a rule.
• Fail the task only if the first controller does not match a configuration rule — Reports a failure if the first
controller detected (usually the embedded controller) is not configurable by a rule.
• Fail the task only if none of the array controllers match a configuration rule — Reports a failure only if all of the
controllers in the system fail to match a rule; in other words, none of the controllers are configured. This rule
also fails if a controller does not have sufficient disks to configure a RAID.
4. You can:
• Add new controllers and define rules for them, or edit the default controller and define the rules. For more
information, see Controllers.
• Add or edit variable conditions for the default controller or the controller that you add. For more information,
see Variable Conditions.
• Create new arrays from a variable condition, if required. For more information, see Arrays.
• You can create an array, add additional disks, hot spares, or global hot spares to the array.
5. Click Save to save the profile as a .XML file.
You can also import an existing profile and modify the configurations using the Array Builder. For more information on
importing a profile, see Importing a Profile.
About Creating Array Builder
When you use the RAID profile that you created using Array Builder as part of the operating system deployment of DLCI
for Configuration Manager, it detects the existing controller(s) on the server as well as the disks attached to each
controller. It then tries to match the physical configuration(s) that the utility detected, to the logical configurations you
defined in the configuration rules. These array configuration rules are defined using a graphical, logical layout that
allows you to visualize how your array controllers will be configured. Rules are processed in the order displayed in the
Array Builder tree, so you know exactly which rules have priority.
