Dot Hill Systems II 200 FC service manual Set up an IP address for the controller

3.Set up an IP address for the controller.

See “Establishing Communications With An Array” on page 4-25.

Note – For detailed information in performing steps 4–14, refer to the SANnet II Family RAID Firmware User’s Guide for optimization mode guidelines.

4.Check the status of the available physical drives.

5.Determine whether sequential or random optimization is more appropriate for your applications and configure your array accordingly.

6.Confirm or change the Fibre Connection Option (point-to-point or loop).

7.Revise or add host IDs on host channels.

The IDs assigned to controllers take effect only after the controller is reset.

8.Delete default logical drives and create new logical drives.

Note – While the ability to create and manage logical volumes remains a feature of arrays for legacy reasons, the size and performance of physical and logical drives have made the use of logical volumes obsolete. Logical volumes are unsuited to some modern configurations, such as Sun Cluster environments, and do not work in those configurations. Avoid using logical volumes and use logical drives instead. For more information about logical drives, refer to the SANnet II Family RAID Firmware User’s Guide.

9.(Optional) In dual-controller configurations only, assign logical drives to the secondary controller to load balance the two controllers.

Caution – In single-controller configurations, do not disable the Redundant Controller setting and do not set the controller as a secondary controller. The primary controller controls all firmware operations and must be the assignment of the single controller. If you disable the Redundant Controller Function and reconfigure the controller with the Autoconfigure option or as a secondary controller, the controller module becomes inoperable and will need to be replaced.

10.(Optional) Partition the logical drives.

11.Map each logical drive partition to an ID on a host channel, or apply a host LUN filter to the logical drives.
