G.4 Understanding LUNs and Viewing
LUN Information
Each SM module supports up to 64 FC logical unit numbers (LUNs), or 128 after a failover, that are
numbered zero through 63. There are three different types of LUNs: CAPI, EMP, and partition. You can
view information about each LUN. See
The three types of LUNs have the following characteristics:
• CAPI LUN: Allows CAPI to configure the SM module. Each X24 can have a CAPI LUN. You only
196
need to assign a CAPI LUN if you are using CAPI to configure the X24 over a host channel using
SCSI protocol extensions. If you are not using CAPI, you can set the CAPI LUN to NONE. If you are
using CAPI, you can set it to a value of 0-63. For more information about changing the CAPI LUN,
see
G.3, "Configuring the Host Channels", on page
Note: Most UNIX, Linux, and Macintosh operating systems require that the CAPI LUN be set to a
higher value than all array LUNs. Before creating your first array, change the CAPI LUN to a
higher value. If you are using a custom software application to configure and manage the
controller (this application uses CAPI to communicate with the controller), you must have a
CAPI LUN. If you are not using a custom application, and therefore are not using CAPI, select
NONE as the CAPI LUN. This allows your first array to be seen at LUN 0.
