NOTE: Most UNIX, Linux, and Macintosh operating systems require that
the CAPI LUN, which is the LUN assigned to each SM, 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 EF2800), 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.
The system warns you about the LUN for UNIX and Macintosh, as
above, the first time you create an array. Press <Enter> and the
system asks if you want to be warned again. Select
No
to avoid
receiving this warning again or select
Yes to be
warned the next
time you create an array.
