Controllers
Controller elements contain variable condition elements. Controllers can be one of several configuration types:
• The embedded controller
• A controller in slot "X"
• Any controller with "X" disks
• Any controller with "X" disks or more
• All remaining controllers
Adding a Controller
To add a controller:
1. Select a controller from the list, or select an embedded controller.
The Controllers drop-down menu to your left is enabled.
2. Click Controllers→ New Controller .
The Controller Configuration window is displayed.
3. Under Controller Selection Criteria, select from the following options:
• Select the controller located in slot — Enter the slot number of the controller.
• Select any controller with < exactly, atleast > < number of > disks attached — Set a rule to select any controller
which matches exactly, or at least the number of disks you have selected.
• Select all remaining controllers in the system regardless of configuration
4. Under Variable Matching Criteria, you can set a rule to apply this configuration only if it matches certain criteria
that you select. Select Apply this configuration only when the variable to enable the rule setting options apply.
5. Click OK.
Editing a Controller
To edit a controller:
Select the controller and click Controllers → Edit Controller. The Controller Configuration window is displayed where
you can make changes to your controller.
Deleting a Controller
To delete a controller:
1. Select the controller and click Controllers → Delete Controller .
A warning informing that all the attached arrays and disks will be deleted is displayed.
2. Click Yes to delete or No to cancel.
NOTE: At least one controller is required on the server. If there is only one controller and you delete it, a
message is displayed that the default controller was inserted because the last controller was deleted.
Variable Conditions
To provide the ability to use the same RAID configuration in multiple logical configurations, variable evaluation is
provided so that a different configuration for arrays and logical drives can be applied to different situations.
Variable condition elements contain arrays and global hot spares, and are of two types:
• No variables defined: This is the default configuration inserted with every controller, and cannot be removed or
moved from last in the order.
• Variables defined: This is where any variable is compared to a value using one of the pre-defined operators.
