SCSI information
SCSI information is listed separately for the primary SCSI channel and secondary channel, if
a second channel is being used. The following data are shown. Refer to Setting SCSI
parameters earlier in Chapter 5 for configuration details.
LUN map: ACS-8990 supports up to 16 logical units in total. Slices must be mapped to logical
units to be accessible by the operating system. The LUN map shows which slices map to
logical units. A typical readout may show:
LUN Map:

x x x x x x x x x x x x x x x x x x x x x x)
In this case, five slices have been mapped. The operating system will be able to access each
of these as a distinct logical unit. Furthermore, the LUN map shows that the operating system
can access two separate arrays. Array 1 contains three logical units / mapped slices denoted
10, 11 and 12. Array two has two logical units / mapped slices, 20 and 21.

SCSI information is given only for controllers with a SCSI interface
daughterboard. Equivalent fibre statistics are given for controllers with fibre
daughterboards. See following section.
