NonStop NS16000 Series Planning Guide (H06.11+)

Because the IOAM enclosure contains two modules, one IOAM enclosure can provide fault-tolerant
paths. However, the paths must be configured through both modules. For example, you could
configure these paths through four FCSAs:
SlotModuleGroupPath
0202110Primary
0203110Primary backup
0403110Mirror
0402110Mirror backup
These paths all exist within the same group. But they are divided between two modules, so the
configuration is fault-tolerant. For additional information, see “Fibre Channel Devices” (page 92).
