Understanding LUNs and Viewing LUN
Information
The RAID controller supports up to 64 SCSI LUNs, numbered
0 through 63. There are three different types of LUNs:
■ Controller LUNs—Assigned when you are using CAPI to
configure the controller over a host channel via SCSI protocol
extensions. If you are using CAPI, set the controller LUN to a
value between 0 and 63. If you are not using CAPI, set the
controller LUN to None.
Note: Most Unix, Linux, and Macintosh OSs require that the
controller LUN be a higher value than all array LUNs.
Before creating your first array, change the controller LUN
to a high value or select None (best choice) if you are not
using CAPI to manage the arrays. This allows your first
array to be seen at LUN 0.
