Software Operation ManualSCSI informationSCSI information is given only for controllers with a SCSI interfacedaughterboard. Equivalent fiber statistics are given for controllers with fiberdaughterboard. See following section.SCSI information is listed separately for the primary SCSI channel and secondary channel, if asecond channel is being used. The following data are shown. Refer to Setting SCSI parametersearlier in Chapter 4 for configuration details.• SCSI ID• Speed• Wide• LUN mapLUN map: YOTTA RAID supports up to 16 logical units in total. Slices must be mapped tological units to be accessible by the operating system. The LUN map shows which slices map tological units. A typical readout may show:LUN Map: (10 11 20 21 12 x x x x x x xx x x x x x x x x x x x x x x x x x x x x xx 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 ofthese as a distinct logical unit. Furthermore, the LUN map shows that the operating system canaccess two separate arrays. Array 1 contains three logical units / mapped slices denoted 10, 11and 12. Array two has two logical units / mapped slices, 20 and 21.Fibre informationFiber information is given only for controllers with a Fiber interfacedaughterboard.
