NonStop NS16000 Series Planning Guide (H06.11+)

This table lists the FCSA group-module-slot-port (GMSP) and disk group-module-shelf-bay (GMSB)

identification for the factory-default system disk locations in the configuration of four FCSAs, four

Fibre Channel disk modules, and two IOAM enclosures:

Daisy-Chain Configurations

When planning for possible use of daisy-chained disks, consider:
